    Bullerbegränsande åtgärder för byggnation nära befintlig väg2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: When cities grow at a faster rate, new places are needed to build housing.The municipalities that are growing tends to choose build sites that previously wererejected due to noise pollution. There are requirements from the state that the noise maynot exceed certain values. The requirements originate from the fact that over twomillion swedes are exposed to noise daily. Noise can lead to health problems, in theform of sleep disorders and cardiovascular disease. To reduce health problems noiseinvestigations are made, where suggestions are made in how noise levels can bereduced. The purpose of the work is to provide the reader with knowledge of whichfactors influence noise investigations and the approach to the choice of noise reductionmeasures so that construction can be made closer to trafficked roads.

    Method: The methods used are literature studies, document analysis and interviews.The literature gathered consists of scientific articles. The documents consist of noiseinvestigations conducted by different companies all over Sweden. Persons to interviewwere chosen from the conductors of the noise investigations documents.

    Findings: To answer the report's purpose, three questions were raised. The firstquestion deals with noise-reducing technologies and which technologies are used today.The report found that there are several ways to reduce noise. In the following order, themost frequently used are: silent facade, noise screen, speed reduction, distance betweenhouse and roads, vegetation, road moving and quiet asphalt. The second question of thereport addresses the factors that influence the choice of noise reduction measure. Fromthe literature study, absorption, reflection and reduction were found to be importantfactors. In the document analysis, surroundings, traffic and speed emerged as importantfactors. In the interviews, aesthetics and price emerged as important in the choice ofwhich reducing action should be taken. The third question deals with the question ofhow construction can be made closer to the road. In the result it appears that all of thesolutions mentioned earlier have the ability to reduce noise, but how effective they areand how well they reduce noise varies from case to case. Surroundings and trafficvolume are of great importance.

    Implications: Making use of the technical solutions previously described, results in areduced noise level and there for construction near road can be made possible.Executing a noise investigation at an early stage means that later and more expensivechanges can be avoided, which means that construction can take place sooner. Thereport suggests therefore that noise issues should be considered early in projects. It isalso important to get a solution that everyone can accept.

    Limitations: The report's results are limited to a smaller selection of noiseinvestigations and interviews. More investigations and interviews could hadcontributed to a larger spectrum. The report does only consider noise outdoors and whatopportunities for noise reduction there are.

    PREFABRICERADE SMÅHUS PLANLÖSNINGAR: En jämförelse mellan tillverkare och kund2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med arbetet är att analysera utformningen av planlösningarna i prefabricerade småhus. Resultatet ska kunna utnyttjas som underlag vid planlösningsutformning och möjliggöra planlösningar med färre kundändringar.  

    Metoder som används är litteraturstudier, intervjuer och en fallstudie. Fallstudien är gjord med material från företaget Anebyhus som tillverkar prefabricerade småhus. Ur en av deras kataloger valdes tre olika hus med snarlika förutsättningar. Det som analyseras är tillverkares och kunders prioriteringar samt de vanligaste kundändringarna. Problemet är att om kunden ska bli nöjd med den slutliga planlösningen måste kunden och tillverkaren ha liknande kvalitetsprioriteringar. Ändringar som återkommer frekvent är ett tecken på en svaghet i ursprungsplanlösningen.

    Resultaten visar att tillverkare av prefabricerade småhus möter kundernas behov och önskemål genom prioriteringar av livslångtboende och flexibilitet i planlösningen. Kunderna visar prioritering av mer bänkytor i köket, vardagsrummet storlek och samband till köket och att alla i familjen ska få varsitt sovrum. De kundändringar som förekommer mest frekvent är minskning av antalet klädkammare, sammanslagning av teknik och klädvård samt att ändra till en U-formad köksuppställning.

    Socialt hållbart boende2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    We need more research about what gives man good conditions for quality of life in a home environment. Social sustainability is a topic that is cherished more than ever in the world of architectures. The goal is to develop a knowledge base based on the experiences of users, architects and clients that can be used for the design of residential areas with apartment buildings.

    To achieve the goal there are questions to be answered as: "How is socially sustainable housing valued, according to architects and clients, when residential areas with apartment buildings are designed?" and "How are the values of social sustainability perceived, in residential areas with newly constructed apartment buildings, of the residents?" The questions are answered by means of an survey and several of interviews which together constitute a qualitative research.

    The results show that social sustainability can be seen from different angles. It is common to observe social sustainability from a community perspective and from an urban perspective according to scientific references. As an overall summary it is the beautiful shape and appearance of a building and its functionality weighed in with a reasonable cost that creates a socially sustainable housing according to interviews with architects and clients. It is about balance between beauty, functionality and economy, which together create a housing that lasts over time and confirms the human social dignity. According to those living in the area of Nysäter in Mölnlycke as the studied phenomenon, socially sustainable housing stands for comfort, security, privacy and community. Access to nature and outdoor activities, fresh air and good neighbourship are other factors that are highly valued. Socially sustainable housing has therefore connections to both physical parameters as well as non-physical qualities that needs to be linked with each other.

    The summarized results highlight the essential aspects that should be included in the planning of a new residential complex for it to be socially sustainable for residents. The knowledge base has a logical order from analyzing an unspoilt area with its qualities to analyze how the private residence must meet human needs for well-being.

    The Report is wide in its choice of subject tough it is limited to man's relationship to the dwelling and residential area in social contexts, how individuals perceive their environment both in and outside their home. With additional constraints had a deeper research been able to implement on a specific theme.

    Uppvärmning och miljöpåverkan: -en jämförelse mellan fjärrvärme och bergvärme i villa2008Independent thesis Basic level (professional degree), 10 points / 15 hpStudent thesis
    Abstract [en]

    Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.

    The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.

    Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affects

    on the environment compared to several other heating methods.

    This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.

    We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.

    Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.

    We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.

    Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.

    Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.

    The results have thereafter been analyzed and discussed from different angles.

    Uppgradering av prefabricerad villa till passivhus, baserad på en husmodell från Götenehus AB2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Rising energy prices, growing energy use and the current climate debate is a major contributing factor to today's search for new, more economical ways to use energy. The Swedish national building and planning department (Boverket) places greater demands on energy use in new housing. Local governments also place specific requirements on certain residential housing projects in addition to the requirements of Boverket, i.e. only passive houses may be built in certain areas. The terms passive house, zero-energy house and plus-energy house are becoming increasingly common in the construction industry and house manufacturers want  to offer products that meet these new requirements.

    This thesis examines whether it is possible to upgrade a pre-fabricated house so that it meets the requirements to be classed as a passive house according to FEBY (translated - Forum for energy-efficient buildings). The study is based on established calculation and production techniques used in Götenehus AB, a manufacturer of prefabricated homes. A case study based on the upgrade of a house from Götenehus is performed and the results are compared with the original house from energy and economic points of view. The production stage is also taken into consideration to see if the engineering solutions required for the upgrade can be produced with the methods in use today.

    The methodology used to process the subject have been literature studies, a case study, own calculations and consultations with staff at Götenehus and other people, who have knowledge on the subject. Energy calculations have been made using the energy  calculation software TMF-Energy v2.1, which Götenehus currently uses to calculate the energy performance of their houses. The results show that it is possible to upgrade the original house to meet the requirements for passive houses with changes made in the building envelope and heating and ventilation systems. The solution presented includes changes in all parts of the building envelope and replacement of the ventilation and heating systems. Instead of the exhaust air heat pump in the original house, a district heating system in combination with solar panels are used. The ability to combine different systems has been limited to the combinations that were available in the calculation software. The results also show that the investments needed for construction and installations are not financially justifiable. Also, the running costs for the passive house are bigger. The energy consumption for the passive house remains the same as in the original house.

    A more efficient way of building in a developing country, influenced by industrialized building: A case study in Leticia, Colombia2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose:The purpose of this study is to approach a solution to reduce housing shortage, by using inspiration from an industrialized building concept, which can lead to the opportunity for underprivileged people to get a livable housing. The aim is to study how knowledge from industrialized building could be used for a more efficient way of building in developing countries similar to Colombia.

     

    Method:Utilizing literature studies for achieving abutment to published research also giving the authors an observant mind. With this knowledge, participatory observations were made as action research to explore the prevailing procedure when establishing a house. Operating analyzes, interviews were held in Leticia for understanding observed decisions. To be able to critically analyze the results from the interviews and observations, collected data were compared with knowledge based on the authors’ reference frames.

     

    Findings:Keystones identified as the overall concept are applicable on establishments in the western world, since the concept is designed after similar conditions. Capital is required designing a building system as well as establishing a factory for prefabrication of elements, conditions limited in developing countries. Climate conditions and prevailing corruption prevents implementation of the concept. Identified weaknesses during the observations, noted repetition of unnecessary and non-value adding activities. One conclusion is not to implement the entire industrial building system, only practice the mindset. Initially keystones are implemented such as planning, exchange of information and reflection of performed projects, in order to improve upcoming projects. These keystones require no direct capital, merely a mindset that should be implemented.

     

    Implications:The outcome of this study is to enlighten the subject, since obvious weaknesses were noticed, with capacity for development. Further research is realistic because, in a long term it will help solving the housing situation. For example, using this result as underlay for education like creating more efficient building, enlightening planning for reducing unnecessary non value-adding activities. As a conclusion of the study, identified weaknesses during the establishment affects the efficiency, creating unnecessary costs. A developing country should focus upon emphasizing reduction of costs, since their economic status is already declining.

     

    Limitations: The observations during the case study have been concentrating on one small-scaled project in Leticia, Colombia. No further observations have been made but complements such as literature studies and interviews. Due to lack of time and language barrier, the amount of collected empirical data was too limited to provide durable conclusions for question formulations. Since only observations were performed on one establishment, a general result cannot be submitted.

    Varför vill inte fler vara skyddsombud på byggarbetsplatser?2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: A stated problem in the construction industry is to recruit and keep safety officers. The lack of willing and engaged safety officers could result in lower safety at construction sites. The purpose of this report is to examine how the safety officers are currently experiencing their work environment and examine what can be changed to improve the situation. 

    The aim of this thesis is to find out what can be improved for more people to want to be a safety officer. This is examined by the main question: Why do not more people want to be a safety officer? The main question is answered by two sub-questions:

    • Which difficulties exists in the role as a safety officer? 
    • What changes needs to be done to improve the situation?

    Method: To reach the aim of the report a case study was performed. The case is Skanska Hus Väst and is limited to the profession safety officers. The method of investigation is interviews and questionnaires, which are qualitatively conducted. The interviews are conducted with the chief safety officers. The chief safety officers can see the broad picture of the situation since they continuously keep contact with all the construction sites in their district. The questionnaires are sent to all the local safety officers in all the districts in the entire region. 

    Findings: One reason for the lack of engaged safety officers is that they do not receive the necessary respect and response from their coworkers. It makes them feel alone. There is no acceptance for safety work and the time that is needed, which give the safety officers a bad conscience when they are forced to leave their work partner. To improve the situation the safety officer’s must receive more respect from their coworkers. Knowledge and acceptance concerning safety must be improved among all workers on the construction site. The safety officers need to feel that they can, and are allowed to, influence the project. 

    Implications: To solve the problem the current safety officer’s situation must be improved. If the existing safety officers are pleased they will give a positive picture of the role to their coworkers, the potential new safety officers. The safety officers’ situation can be improved by the points that follows:

    • The safety officers must receive more respect from others in the construction site. 
    • The safety officers should advantageously be placed separate from the time plan of the project.
    • The safety officers should be involved in an earlier stage of the project. 

    Limitations: The report has been limited to only examining the role of the safety officer and their own perspective. The views of safety officers from the perspective of other roles at the construction site has been omitted from the thesis. The report does not investigate how to perform the changes.

    Kartläggning av sex kommuners planering av kollektivtrafiken i nya bostadsområden inom Jönköpings län2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: Today we can see a steady increase in population, which calls on the municipalities to plan new residential areas and develop the old ones. This in turn leads to pressure on public transport with a focus on environmental issues and a desire for a different way of transport than by car becomes more and more relevant. The purpose is to give an overview and to understand the planning of public transportation today for six municipalities in Jönköping County.

    Method: The report has been conducted using qualitative studies in the form of interviews and literature studies. Document studies have also been used and have been downloaded from the municipalities' websites. Findings: When planning new residential areas, the municipalities try to bring public transport into account. In some municipalities, public transport has a more significant part in planning. If the municipality fail to achieve the aims of public transport planning, it will mainly result in negative environmental impacts. For the municipality to develop and make sure that the number of inhabitants increases, public transport should be an important part of the planning. When it comes to the cooperation between Jönköpings Länstrafik and the municipalities, they focus on public transport and that It will cover the need for travel in the municipalities. It is important that you already in the early stages of planning make sure that there is room for the public transport that is required.

    Implications: Public transport must continue to be a major part of planning and focus should be on realizing what is planned for public transport. Although the municipalities are planning public transport, there are residential areas that could have a significantly better access to public transport.

    Limitations: As time was not enough for a study covering all 13 municipalities in Jönköping County, it was decided to focus only on six municipalities with different circumstances and varying sizes.

    Abstract [en]

    Abstract

    Purpose: The purpose of this thesis is to map the level of knowledge and demand that the clients in today's construction industry have of the BIM aid. This will be achievedby identifying the possibilities and obstacles they believe that BIM causes the project.The aim is to develop a proposal on how to increase the use of BIM in the Swedish construction industry.

    Method: This thesis covers an analysis of the current situation regarding the client’s knowledge of a specific topic, qualitative interviews were chosen to enable the respondents’ answers to be developed after their personal experiences. Both interviews and literature studies were conducted to identify the pros and cons of BIM since a comparison could be made between the client's assumptions against the theory. In order to develop a proposal on how to increase the usage of BIM, all the previously collected data was combined to develop a foundation that is then built up with the collected empirical and theoretical data for the specific question.

    Findings: BIM is a foreign term for most of the clients in today’s industry, which makes the demand for correct BIM-models minimal or non-existing. Although the benefits of BIM creates more efficient, productive and quality-proof projects, the lack of knowledge, competence and proven projects in the Swedish construction industry creates a fear that makes the actors wait to make an investment. Therefore, the clients usually choose the visual short-term profits over the long-term profits.In order to streamline the usage of BIM an increased understanding of the potentials that BIM holds is needed. Competence development, training, a show of BIM completed projects in the Swedish construction industry, an appointed BIM coordinator in the early stages of the design processes and a standardization of a fileformat.

    Implications: BIM has a great potential in the construction industry. The use would mean a simpler and clearer process for the involved actors, which would benefit the engineers’ work, since safer and more effective calculations would be presented. This could result in lower overall costs, reduction and prevention of errors. However, the competence and knowledge of many of the clients are lacking at present and the use of BIM is considered unrealistic as one needs to readjust the entire market and perform an intensive learning process during the boom.

    Limitations: The thesis has been carried out in the Småland region and is limited to the client's perspective and a few entrepreneurs' perspective of BIM.

    Keywords: BIM, Clients, Developers, BIM streamlining.

    Abstract [en]

    This report will try to evaluate the use of rented concrete casting moulds, which are used to build walls and system of joists. The evaluation is only examining the economical aspects.

    The cost of using concrete casting moulds is a big part of the total production expenses. Therefore it is important that the calculated price not exceeds the final costs of the casting moulds. The calculated price is the price used in the process of making an offer.

    The evaluation consists of a comparison of the calculated price and the final costs for three building projects. It also evaluates the exploitation of the concrete casting moulds for each project.

    The report is made by Sven Gynne and Anders Alexandersson at School of Engineering, Jonkoping University, in cooperation with PEAB Jonkoping. The evaluation is strictly based on the calculated price and final cost of rented concrete casting moulds, only the moulds themselves, not the labour costs.

    Educational visits have been made to the three projects gathering facts. The conclusions we have drawn are that the difference between the calculated price and the final costs are considerable, especially one project have a greater difference than the others. The reasons for that are among other things tight building ground and a complicated building construction.

    Klassificeringssystem för hållbar stadsutveckling2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The urbanization is increasing while there is a comprehensive climate change in the world. The cities stands for 70 percent of the global carbon emissions and two-thirds of the world's energy use. Half the world's population live in cities. Because of this, it is necessary that cities are sustainable. Therefore, there are various classification systems for neighborhoods that facilitates the creation of a sustainable city. However, there is no Swedish system but Breeam Communities is adapted to Swedish conditions.

    The objective of the report is to contribute to the development of methods that support sustainable urban development. By first identifying the classification systems, these could be compared with each other to see which criteria’s recurred. Parallels could be drawn as to which was more important, as the majority made use of these criteria. A sketching was made to find out what criteria should be included in the Swedish system and the regular criteria of the investigated classification systems were also very helpful.

    The systems that have been investigated are Breeam Communities, Casbee for Cities, One Planet Communities, Green Star Communities and Leed for Neighborhood Development. The systems measure sustainability usually infactors/criteria of social, economic and ecological aspects. Classification systems have different requirements or goals of what needs to be achieved within each factor. The systems are very different designed which complicated the comparison process.

    The regular criteria in all systems are carbon, water consumption, water pollution, food, wildlife and nature, floods, waste management, developed land, physicalactivity, accessibility, health and welfare, culture and heritage, transport, greenspaces, community involvement, light pollution, local economy and employment.

    Since Sweden has its own climate and its own standards, a foreign system is not adapted so easily to Swedish conditions. The criteria that should be part of a Swedish system is partly based on the global and national goals for Sweden as wellas those returned in the analyzed systems. In addition to the criteria that reappeared in the systems (some of the criteria has been renamed) it should also contain noise, nature, traffic, mixed development, security, maintenance and education.T

    There are many factors within the three perspectives to be analyzed and utilized to achieve a well-organized and good classification system of neighborhoods. There are many benefits of a classification system. For example, it facilitates informed choice, collaboration and communication between actors, but most of all a better society to live in.

    Effektivisering av en tjänsteleverantörs processer: Genomfört som en fallstudie på köksprojekt2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Produktionskostnaderna i byggbranschen ökar ständigt och i en rapport utgiven av

    Sveriges byggindustrier kartläggs att uppemot 30-35 % av den totala

    produktionskostnaden i ett byggprojekt kan betraktas som slöseri.

    Slöseri kan beskrivas som de förbrukade resurser som inte skapar något värde för

    kunden, såsom förflyttning av material, väntan, avbrott, lagerhållning och

    överproduktion.

    Studien är genomförd på köksprojekt där Peab byggservice agerar tjänsteleverantör och

    bistår Ikea med monteringstjänster. Studien baseras på ett rikstäckande avtal som rör

    all typ av montering av Ikeas sortiment, dock har i denna studie endast monteringen av

    kök studerats. De förbättringsområden som har identifierats i rapporten har sedan

    analyserats och diskuterats med hjälp av verktyg från Lean. I rapporten benämns Peab

    byggservice som tjänsteleverantör och Ikea som leverantör.

    Syfte: Syftet med arbetet är att effektivisera en byggtjänsteleverantörs processer för att

    uppnå en ökad lönsamhet.

    Metod: För att uppnå målet och besvara frågeställningarna har arbetet utförts som en

    fallstudie av köksprojekt. Kvalitativa intervjuer och dokumentinsamling har använts

    som metoder och har varit en del av fallstudien. För att inhämta stöd i teorin och

    metoder som lämpar sig i det aktuella fallet har en litteraturstudie gjorts.

    För att identifiera slöseri i den befintliga processen har en värdeflödesanalys uppförts,

    det är ett verktyg från Lean med syfte att synliggöra köer, och andra icke värdeskapande

    aktiviteter.

    Resultat:

    I rapporten har:

    ● Processen gällande ett köksprojekt kartlagts.

    ● Olika former av slöseri identifierats.

    ● Verktyg från Lean analyserats för att minimera slöseri.

    Detta har lett till förslag på:

    ● Reducerade ledtider genom kombinerade aktiviteter.

    ● Kortare processtider genom effektivisering.

    ● Metoder för långsiktiga lösningar för att på sikt uppnå en effektivare process.

    Konsekvenser: Utifrån rapportens resultat konstateras möjlighet till förbättring. Slöseri

    har identifierats och förbättringsåtgärder med hjälp av framtagna teorier bedöms vara

    möjligt.

    Begränsningar: Resultatet är kopplat till generella problem och ger förslag på

    förbättringsarbete i de fall där en entreprenör agerar tjänsteleverantör åt en leverantör.

    Nyckelord: Processeffektivisering, Lean Production, Slöseri, Värdeflödesanalys.

    En utredning av kommunala markanvisningspolicyer: Påverkan av lag 2014:8992016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det är sedan tidigare tydligt att det funnits problem och delade åsikter kring arbetet med markanvisningar innan lag 2014:899 trädde i kraft. Arbetets syfte var att undersöka om arbetet har förändrats efter att lag 2014:899 trädde i kraft. Målet med arbetet är att utreda de valda kommunernas markanvisningspolicyer och deras erfarenheter av arbetet med dessa. Förbättringsåtgärder föreslås efter att ha belyst svagheter i de markanvisningspolicyer som undersöktes, med utgångspunkt i lag 2014:899 samt punkter specificerade av Caesar et al. (2013). 

    Ett dokument med förslag till vad en markanvisningspolicy bör innehålla har tagits fram. Dokumentet kan underlätta kommuners arbete med markanvisningspolicyer i fortsättningen.

    Mindre kommuners arbete med LOU och deltagandet av små byggentreprenörer2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The problem is that small building entreprenuers generally don’t participatein public procurement since they are experiencing the process to be time-consuming,expensive and complicated. The main objective is to produce a proposal for howsmall municipalities can work to make the participation of small buildingentreprenuers in public procurement easier.

    Method: The main objective has been achieved with qualitative enquiries such asinterviews. These interviews have been made with three small municipalities and onesmall building entrepreneur.

    Findings: To make it easier for small building entreprenurs to participate in publicprocurement small municipalities can work with simplifying the administrativeregulations with the help of frequently asked questions from the entreprenurs. They can procure total contracts, partnering-projects or split contracts which afterward iscombined to a coordinated generalcontract. They can also try to keep a good contactwith their local entreprenuers. They can identify which documents that are necessaryto demand at the tendering and which they can submit afterwards. Another initiativeto increase the entreprenuers interest is to organize a gathering where the municipalitycan inform and answer questions about public procurement.

    Implications: The problem is not demarcated just in Sweden but throughout theEuropean Union. The proposal can be used in other member states but needs furtherdevelopment to make a greater difference during a longer perspective. Svenskt Näringsliv (2014) earlier warned that an increase of the direct procurement limitwould affect the competition badly. The essay clarify that the increase did not bringany difference to the competition since the municipalities uses internal guide-lines.The internal guidelines involves internal monetary limits for the municipalities. Thisis to ensure a good competition when procuring direct awards. Hopefully the proposalwill help to solve the overall problem that small building entrepreneurs generallydon’t participate in public procurement.

    Limitations: The essay only covers municipalities with a population ofapproximately 30.000 people, but the problem is most likely present in bigmunicipalities as well. It was a suitable boundary that was made becausemunicipalities with approximately 10 000 people often cooperate with bigmunicipalities. Such a small municipality would not contribute to the empirics thatwere necessary to fulfill the main objective.

    Keywords: Public procurement, Act (2007:1091) on public procurement,Municipality, Contract, Building entrepreneur.

    KOMMUNIKATION MELLAN PROJEKTÖR, BYGGLEDARE OCH ENTREPRENÖR I EN GENERALENTREPRENAD2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of the survey is to investigate the communication between the contractor and the consultant in a construction project with general contract as a procurement form. Communication is lacking in previous research, which has contributed to negative aspects in terms of economics and time. This survey will result in improvement proposals to reduce communication problems.Method: The problem of the study was based on a literature study on communication problems in construction projects. The literature study has also been used to build the theoretical framework. Semi-structured interviews formed the basis for answering the questions in depth. In order to strengthen the interview response.Findings: The survey results in communication problems between the contractor and the consultant and the problems affect the projects negatively. The survey also found that the proportion of general contracts is decreasing.Implications: The conclusion of the survey is that through an increased opportunity for a two-way communication that contributes to improved communication opportunities between the participating players. Recommendations to increase the opportunity are:

    • Use of video calls gives the parties a two way communication.
    • Direct contact between contractor and consultant on technical issues (general contract) provides more efficient technical solutions and reduces the risk of misinterpretation.
    • More importance in providing feedback to all parties.
    • Allow the consultant (projector) to participate throughout the production phase allows for better upcoming actions.

    Limitations: The work is limited to communication between contractor and consultant in a general contract. Interviews were limited to Pontarius AB and NCC Construction with regard to the work time frame. The survey is generally adapted to other companies in the industry.

    Jämförelse av fyra trärena fasadpaneler beträffande utseende, miljöpåverkan, beständighet och kostnad2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Trä är ett förnyelsebart material som bidrar till mindre miljöpåverkan än andra material. Klimatförändringen leder till ökad nederbördsmängd som ställer högre krav på beständighet hos fasader, samtidigt ska ytterligare miljöpåverkan undvikas i bästa mån. Denna rapport utreder modifierat trä, ett sätt att förbättra träs beständighet som inte kräver underhåll och är ett alternativ för framtiden. Målet är att jämföra tre modifieringsmetoder, acetylering, furufrylering och värmebehandling, med cederträ beträffande beständighet, miljöpåverkan, kostnad och utseende för att öka användandet av modifierat trä som trärent fasadmaterial. Metod: Litteraturstudie visade på forskningsfronten för modifieringsmetoderna och dokumentanalysen gav kompletterande data om produkternas miljöpåverkan, utseende och beständighet. Intervjuer gav inblick i aktörernas roller vid valet av fasadmaterial samt klargjorde kostnader för metoderna. Ytterligare intervjuer gav kompletterande data till dokumentanalysen och visade skillnaden mellan beständighet och miljö- påverkan för modifieringsmetoderna. Observationer gjordes för värmebehandlat trä och furfurylerat trä. Resultat: Arkitekter och förvaltare har en stor påverkan på valet av fasad men det är beställaren som fattar beslut. För beställaren är priset den viktigaste parametern och därför skulle de flesta byggherrar välja värmebehandlat trä, det billigaste alternativet. Dock rangordnade de flesta miljöpåverkan som den viktigaste parametern som visar på att aktörerna går mot att använda metoder som är bra för miljön. Acetylerat trä visade sig vara det alternativet som forskare föredrar ur beständighetssynpunkt. Det är viktigt att veta vilka parametrar som är väsentliga för byggnaden och utifrån dem avgöra om fasaden är värd kostnaden som modifierat trä medför. Konsekvenser: Att använda modifierat trä är dyrt, men ett billigare alternativ än cederträ. Aktörerna tycker dig se en framtid för dessa metoder, men eftersom metoderna är dyra är marknaden begränsad till nischade beställare eller detaljplaner och främst användbara i mindre projekt. För att öka användandet av modifierat trä krävs större kunskap på marknaden, flera referensobjekt som kan hjälpa beställare att välja metoden samt tid och pengar i projekt för att utvärdera och välja modifierat trä. Begränsningar: Dokumentanalysen gav användbar empiri, men utbudet var begränsat då det fanns gott om information om vissa behandlingsmetoder och mindre om andra. Intervjuerna gav mycket empiri men visade på en okunskap om metoderna ute i branschen, trots avgränsningen till aktörer som aktivt arbetar med trä i byggnaden, vilket gjorde sista frågeställningen svårbesvarad. Överlag är en begränsning att det endast finns ett fåtal fasader med modifieringsmetoderna att utreda, vilket gjorde observationerna svåra.

    Abstract [en]

    The purpose of this thesis has been to signify what creates quality for the dwellers. By

    creating a definition of the term we have showed how well the quality

    criteria’s has been fulfilled in the newly built one family house area Pumpkällehagen in Viskafors.

    The questions the thesis gives answers to is: What is quality for the dwellers in

    housebuilding of today? and How well have these quality aspects been carried out in tract

    housing areas? These questions have taken us to our main goal: To describe what quality

    for the dwellers is and how well it has been carried out in a certain area.

    The literature review is describing what was published before the making of this thesis.

    From four different publications within the concept of quality an analysis template has

    been enacted. This template has been used for our case study, but is also supposed to

    work in future analysis of tract housing areas.

    Interviews was carried out with the areas architects; Ola Nylander and Mattias Karlsson,

    as well as the client; Mikael Bengtsson. From these we have gathered their point of view

    on the background of the area, as well as their view on the term quality for the dwellers.

    Our work has brought us to enact nine different quality aspects, which we consider

    creates quality for the dwellers:

    • The Non-measurable properties

    • The rooms relative connections

    • Sufficient and user-friendly property complements

    • The property complements connection to the apartment

    • Location of the apartment and connections to the environment

    • Opportunities of outdoor activities

    • Orientation and transportation within the area

    • The social unity

    • The cost of the apartment and its form of tenure

    From the case study, using the analysis template, we can state that Pumpkällehagen is a

    very successfully built area where most of our assessment criteria’s and quality aspects

    have been fulfilled. That makes the quality for the dwellers as a total very high.

    We reach the conclusion that quality for the dwellers is what make you feel comfortable

    in your home, and therefore makes you stay.

    Abstract [en]

    This thesis is ordered by Peab Sweden AB Regional Jönköping and concerns of warranty inspections.

    The intention is to work out a basis, which show the most common complaints is the warranty inspections, and make a small analysis on what causes them to be. The report also presents possible solutions to prevent the occurrence of defects. It also covers the issue of how the client looks at Peabs way to overcome the objections of warranty inspections. The report has the following issues:

    •What are the most common errors observed during the warranty inspection?

    •What are the causes of complaints?

    •What can be done to reduce the number of complaints?

    •How the customer thinks that the complaints be addressed?

    Twenty-five Guarantee survey records from the projects Peab has done in recent years has been the starting point for the investigation. In the protocols, we have categorized the remarks and made a compilation of common remarks. Through interviews with inspectors, buyers, site managers and Peab's inspection team the results have been analyzed and interpreted.

    These survey methods have resulted in various proposals for measures that can reduce the remarks. An example may be to inform professional workers in the building about what the most common remarks are and how to guarantee that these can be prevented.

    The compilation is categorized according to the most common complaints, construction types, actors and types of buildings.The compilation of inspection protocols showed that the cracks are the most common complaints. The interviews gave confirmation that the survey compilations of protocols were equivalent to reality.

    The conclusion is that the most common complaints are mainly cracks in the wall corners, roof angles and doors that need to be adjusted. These remarks are mainly due to the tight construction times, sloppy and wet materials that are installed. But there are also many other factors contributing to many of the common faults of warranty inspection that cannot be defined as a single cause. Interviews with clients revealed that they are satisfied with the way Peab remedy defects observed at guarantees, while the survey does not disturb the residents/production.

    Underhåll av levande väggar: Möjligheter och utmaningar i ett svenskt urbant klimat2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: A slow development of living walls in Sweden is partly due to lack of experience and knowledge in the construction industry. Former studies point at challenges of adapting the technique in a Swedish climate and the importance of planning, knowledge and cooperation for the maintenance. The objective of the study is to analyse a sustainable maintenance by technique and maintenance planning of the system living walls in order to answer these challenges.  

    Method: The study is based on a qualitative approach where the methods are document analysis, interview and observation. Document analysis gives a status report of the implemented living walls in Sweden and introduces strategies for maintenance planning. Interview with relevant participants contributes with experiences concerning technique, maintenance and maintenance planning. Observation confirms the information about the technique.

    Findings: The study shows that none of the observed solutions can be considered completely sustainable, though they do have some sustainable qualities. Living walls have strong social and ecological benefits, where the vegetation contributes to increase ecosystem services in urban environment. A less use of resources is necessary for a sustainable technique where the use of stormwater, local resistant plants, lasting construction and recycled components promotes a sustainable environment and economy. The felt system is simpler in its design while the modular system is more flexible. A common objective among the observed projects is to create a maintenance-free solution as possible. Acceptance for resting plants during winter can lower the demands of the maintenance. Technical monitoring facilitates the maintenance but the manual handling of living walls is crucial. The frequency of the maintenance varies from each project where the client’s choice, placement of the wall, type of solution, size, plant choice and season affect. Therefore, it is important with planning and constantly evaluating a walls needs. The majority of the observed projects do not have a maintenance plan but the study shows success by a common objective, site analysis, goal-oriented maintenance plan and experience feedback.

    Implications: The conclusion of the study is that the technique of living walls needs to be evolved to leave a smaller footprint on the environment and the economy. The development is towards a maintenance-free solution but the manual handling can not be replaced by advanced technique. Every projects individual conditions demands thorough planning and continuous evaluation of the wall.

    Limitations: The study discuss living walls in the Swedish urban climate, where the result is based on experiences from projects developed in the southern part of Sweden. Other geographical placement causes different conditions for technique and maintenance. General assumptions can be made concerning the maintenance planning. More interviews with maintenance staff can contribute with other aspects to the analysis.

    Effektivisering av 3d-projektering2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: Sweden's construction industry is facing great challenges in form of increased housing with the increasing demands on the environment and economy, this combined with the current low unemployment today and many upcoming retirements. To meet these challenges, it requires development and changes which BIM is considered to handle if it is correct performed. 3d planning is an important part of BIM, where it lays the ground for further step in the building process following two steps, production and management.

    Method: Selected methods of this thesis is a literature review, semi-structured interviews and document analysis. In the literature review writings about, or related to, 3d planning was studied. The interview method gave more detailed information about the problems that planners experience in reality. The document analysis created a deeper understanding of how 3d design work.

    Findings: The results show that with simple means it is possible to avoid common problems. Which leads to streamline of 3d design and the entire construction process. This in the form of aspects including economy, the environment and sustainable construction.

    Implications: Development and improvements in 3d design leads to more effective planning which in contributing to more effective construction. Increase of efficiency can now be justified by the savings in the economy and the environment. But visions of development potential in the further step exists today. One step further, for example, be monitoring the working environment in the planning phase. More education in BIM at all levels of the construction industry should create a better understanding of each other and alleviate the communication gaps that currently prevails.

    Limitations: This thesis is limited to the design phase of the building process conducted with 3d modeling.

    Valmöjligheter i samband med prefabricerade badrum2007Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    This report deals with prefabricated bathrooms and the advantage, during the production process, they have compared to ordinary produced bathrooms.

    The work is done together with the building company JM. The common task is to investigate if the manufactures, in spite of standardized design can meet the concept of JM, i.e. high flexibility and adjustment towards the customer. In JM they are doubtful to the method, as they did not yet worked with prefabricated modules and think that the choises for the costumer will be limited.

    There will be a short resume of the progress of the bathrooms and its importance as sanitary and wellbeing.

    The recent problems with damage caused by damp in bathrooms. Have resultade in regulations. These rules, will be briefly reported.

    There will also be a short review of some interviews with persons who have experience of prefabricated bathrooms.

    Different manufacturing methods will be reviewed and how different modules will be installed in to the houses.

    Concerning the economy we have accepted the figures of the manufactures.

    Prefabricated building is a method to shorten the production time on the working site. It will be done through manufactoring buildingblocks in factories. The blocks could be simple beams or complete modules. Therer is a great deal of advantages for instance the productions will not be depending of the weather.

    The quality will also be more uniform, since each part is produced independent of earlier parts.

    We have learned about the planning process, construction and installing and we think that not only JM but also other building companies could have a lot to win in this way of building

    The problems we have noticed are:

    • Very accurate planning is required from the contractors

    • The transporting factors restrict the flexibility and the size of the modules

    • The modules take more space than the ordinary way to build

    • The modules required depression in the ground beam layer in the area where it should be placed. This will be calculated for during the constructing period.

    Problematik och lösningar vid våtrumsstambyten2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Litteraturstudier visar att det mellan år 1961 och 1970 byggdes 600 000

    flerbostadshus i Sverige, tiden är nu inne för en renovering av dessa byggnaders

    våtrumsstammar. De tekniker som konkurrerar om de stora renoveringsarbetena

    är den klassiska stambytesrenoveringen, Relining och Prefab-badrum. Huvuddelen

    av denna uppsats utgörs av en undersökning av de tre teknikerna men rapporten

    beskriver också problem som kan uppstå vid renoveringar av våtrumsstammar och

    den ger en allmän redovisning för Sveriges byggnadsbestånd.

    Den klassiska stamrenoveringsmetoden, då det gamla badrummet rivs ut och ett

    nytt badrum byggs upp utifrån den gamla stommen, är ett omfattande och

    tidskrävande projekt. För att minimera bland annat kostnader, byggtid och

    byggavfall har man tagit fram nya, mindre tidskrävande tekniker.

    Så sent som år 1990 gjordes den första Relining renoveringen i Sverige. Denna är

    idag intakt vilket tyder på att livslängden för denna typ av renovering är minst 18

    år. Tack vare att rören gjuts får de nya rören varken fogar eller skarvar, vilket

    minskar risken för fuktskador. Efter ett stambyte då man använt sig av Relining

    kan dock en mindre kunnig konsument tro att badrummet är intakt och kommer

    att så vara en lång tid framöver, men eftersom endast ledningarna renoveras, skulle

    detta kunna leda till att ett tätskikt kan fortsätta att läcka utan något ingrepp görs.

    Prefab-badrummen, vars teknik också är ny, bygger på att ett nytt badrum byggs i

    det gamla, vilket minimerar rivningsarbetet. När Rum i Rum AB renoverar

    badrummen använder de sig utav en ventilationsspalt för att eventuell framtida

    fukt ska kunna ventileras ut genom öppningen vid tröskeln in till badrummet.

    Detta är en prisvärd renovering som innefattar ett framtidstänkande, då eventuella

    läckor kan upptäckas direkt så några skador inte hinner bildas. Det finns dock en

    risk för en ”prefab” känsla ges, det vill säga mindre valmöjligheter när det gäller

    utformningen.

    Nu när miljonprogrammet kommer att behöva en stamrenovering anser jag att

    Prefab-badrummen är det bästa alternativet. De flesta av dessa badrum har

    liknande eller till och med samma utformning, vilket skulle gynna den utvecklade

    logistiken som finns inom Prefab-badrummen för att då hinna med all renovering

    som behövs.

    Prefabricerade Passivhus2011Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    European Union has made a new decision that all new built houses by 2020 shallbe near-zero energy houses. Boverket’s definition of near-zero energy housesintends buildings with good energy performance in which a proportion of theamount of energy that must be added to the building is made of renewable energy.Passive House is a set of requirements from FEBY designed to build energyefficient buildings. This is achieved by reducing loss of heat through the buildingenvelope and to take advantage of the passive heat from solar radiation,installation and heat sources like people living in the house.This project has been made with help of Anebyhus and one of their model houseshave been examined from the report’s issues, including Anebyhus’s energyperformance, requirements for the manufacturing and assembly, how theenvelope must be improved to fulfill the requirements for the Passive House andwhat energy calculation programs are available on the market.The report aims to provide solutions for energy efficient houses that are adaptedfor production of house building.Two visits to Anebyhus has been done to study their manufacture and assemblyof building elements. The Energy calculation programs that have beeninvestigated calculates the specific energy consumption of a building.Anebyhus manage today BBR’s requirement of 55 kWh/m2 and year, but has notbegun designing or building any Passive Houses. They have no specialrequirements for the design of their houses only that it should be possible to buildusing their present manufacturing and assembly process. The dimentions of thebuilding elements is mainly restricted by the ability to transport the items on thetruck to the construction sites.The important part of prefabricated construction is the assembly because it isimportant that the house is built tightly so that no moisture or air leakage gets into or out of the building. This is particularly important in Passive House buildingas the construction making demands higher accuracy.The focus of the report is on the building envelope to Anebyhus’s model house.To manage the stricter requirements that Passive House needs the whole buildingenvelope needs to be replaced with better insulated constructions. Also theheating and ventilation systems must be changed to handle the requirements.Energy calculations were made both by hand and by using the energy calculationprogram TMF. The results show that the Passive House we studied just manageFEBY’s demands for a Passive House, which is 50 kWh/m2 and year when solarpanels are installed on the roof to cover the needs for hot water in the summer.The conclusion is that Anebyhus doesn’t have a particularly long way to go in thePassiv House technique, as the house Sadelvägen, which we studied, basicallyfulfill the requirements for a low-energy house. To meet the requirement withoutthe solar panels, extra insulation would be needed, though the machines atAnebyhus aren’t capable of that today.

    Etablering av turistboende i fjällmiljö2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Sälen is the biggest ski resort in northern Europe and is under development to meet the tourist requirements. Skistar AB own and manage ski resorts in Sweden and Norway. Skistar AB is planning for a new Skilodge in Hundfjället housing 300 beds to enhance the area as a ski resort.The purpose of our final thesis work is to gather knowledge about how tourist housing in ski resort works. The aim is to investigate controlling factors when you exploit a tourist housing in the mountains. This will end up in a proposition of a Skilodge in the centre of Hundfjället.

    After meetings with Skistar AB diagrams with wanted functions and spaces have been worked out. Inventories of the area have been done at the site in the centre of Hundfjället where buildings and surroundings have been inspected.Reference projects have been studied in literature and on the Internet, but also on site in Sälen. Different types of housing have been studied to get an understanding about housing in the mountains. Laws and rules have been investigated as well as the expression “Storslagen Fjällmiljö” because these resorts lies in sensitive ecological environments and animals and environments needs to be taken under consideration.

    Based on these conditions and the troll theme in Hundfjället a proposition of a Skilodge has been designed. This proposition will later on be presented for Skistar AB.

    Tourist housing in the mountains are often located in remote locations and that influences the functions to be compared with regular apartments, houses etc. and its functions. Natural material as wood and stone are reflected in the buildings.

    Dagvattenhantering inom starkt hårdgjord radhustomt med jord av begränsade infiltrationsegenskaper.2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The problem with hard surfaces, as for example asphalt and roofing, is that they do not absorb enough rainwater. Furthermore, this leads to that grass surfaces and other absorbent surfaces around having to take care of all stormwater that the hardened surfaces cannot infiltrate. Flooding in urban environments has become increasingly common due to heavy rain and a high proportion of hard surfaces. This leads to an overload of the pipe line for rainwater. Therefore well-functioning balancing trays close to source needed to mimic natural drainage of nature. The goal was to investigate witch countervailing magazine mainly should be applied in heavily paved small terraced plots, where the soil has limited infiltration properties, in terms of efficiency, cost and maintenance.

    Method: The methods used to meet the objective is analysis of documents, qualitative interviews and a case study. The document analysis serves as a basis for the case study and interviews serve as empirical input for the case study.

    Findings: The countervailing magazine that is preferred is the pipe magazine when the plant surface is limited and the soil has limited infiltration properties.

    Implications: The problem statement treats the issue with an increasing number of floodings in urban environments due to the paved surfaces and the heavy rains. Furthermore, it is disclosed that the management system therefore risks becoming overloaded. This problem was also confirmed in the interviews. The work did not identify which countervailing magazine that is preferred for all kinds of cases, but only in the cases where land space is limited and where the soil has limited infiltration properties. The solution is therefore that pipe magazine is the magazine preferred for local disposal of stormwater in those circumstances. It is recommended when applying this result real life, to use the cost per meter and countervailing volume per meter available in efforts to work out how long stretch pipe magazine needs to be built on to achieve the desired equalization volume. Rating systems made for maintenance can however be used for other cases.

    Limitations: The result is applicable in similar scenarios as for the case study, which is at a row house site where the surface for the magazine is limited and where the soil has limited infiltration properties. A graph has been developed for the work where the construction cost per meter is described for each countervailing magazine and also has a graph with stormwater volume per meter been developed. These diagrams can therefore be applied to other cases with small areas but with other measures of the plot. Therefore the result also is applicable to other cases.

    Analys av kommunikation under projektering i partnering2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: During the planning phase of a construction there are many participants

    involved; architects, building contractors, constructors, developers and so on.

    Communication problems occur between these participants and may lead to wrong

    planning and high costs. Partnering focuses on relationship-building, transparency and

    trust, which in theory should reduce the problems for a project. The objective of this

    study is to analyse the communication in the planning phase to identify how

    communication problems can be prevented in a partnering.

    Method: To achieve the objective, literature studies and interviews have been

    selected as methods. The interviewees were selected from two partnering projects that

    Skanska was involved in.

    Findings: Results show that partnering reduces communication problems and create a

    greater involvement and commitment of the project planners. However, some problem

    still exists such as the use of project portals, choice of communication channels,

    coordination and information transfer on a formal and informal level.

    To prevent these problems, literature studies and interviewees contributed a few

    examples; a detailed meeting agenda, add comments on the blueprints, production

    personnel should participate in planning meetings and economic incentives. The

    interviewees have felt that partnering has worked well which has produced good

    results during the project planning.

    Implications: To create an effective planning group and remove the participants own

    interest, partnering should be applied. Planners should work with one project at a time

    and should be located with each other to benefit the work and communication at

    formal and informal level. Planners should work in a project portal that they are

    experienced and comfortable with.

    Limitations: This thesis will only analyze the planning stage. The two analyzed

    partnering projects were under planning stage during the thesis, which made it

    impossible to continue the research on the handover phase from planning to

    production. The interviewees have been limited to architects, contractors,

    constructors, developers, electrical and plumbing planners.

    Keywords: Planning stage, communication, partnering, communication problems

    Integration genom fysisk planering: Ungdomars inflytande i byggprocessen2011Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    We live in a time where the influence of citizens is taking a larger role in the spatial 

    planning. The Swedish laws, such as PBL, deals with matters of citizen participation 

    which advocates that the youth should be included in the consultation circuit, but there is 

    no directive given.  

    The report's purpose is to demonstrate methods for how to get the young people's 

    influence included in the spatial planning, with a main focus on the ages between 13 and 

    21. On the base of literature and two case studies, the goal is to illustrate how to integrate 

    young people through a meeting place in Jonkoping, Sweden. 

    The report is structured along with an analysis based on the literature, two case studies 

    from previous projects and discussions/interviews with young people from four selected 

    areas in Jonkoping.  

    The case studies from Malmo and Gothenburg show how the cooperation between 

    different participants can be organized during the planning and how to give the users a 

    greater involvement. 

    Based on literature and case studies, we carried out a field analysis of the four most 

    segregated areas of Jonkoping; Osterangen, Oxnehaga, Ekhagen and Raslatt. Young 

    people in these areas were interviewed, as a basis for a proposal for a new all-activity 

    center at the expended location of Kungsang School. 

    During this project, the following three issues were investigated:

     

    In what need are young people of a meeting place in Jonkoping?  

    Our research has proved that there is no greater connection between the young people in 

    Jönköping, because the young people appear generally in their own neighborhoods. 

    Therefore, segregation patterns are created and there is a need for a common meeting 

    place, a place in the municipality of Jönköping would be of great value to promote 

    integration between young people. 

    What can an all-activity house contribute to in Jonkoping? 

    An all-activity house which is available for everyone would contribute to what young 

    people are missing, by being a meeting place for everyone in the municipality of 

    Jonkoping. 

    Based on literature studies we believe that an all-activity house will break the segregation 

    pattern and reduce the distinction between "us" and "them", which will result in a more 

    integrated environment. By involving young people from the beginning until the end of 

    the projects, their influence will increase and it will give a wider understanding of their 

    neighborhoods and needs. This should be done through meetings and open dialogues 

    between users and planners. To assessment the degree of influence, Arnstein’s step 

    model can be used. An all-activity house with a wide range of activities benefits the 

    participants’ health by making them active and enabling conditions for movement. 

    School activities are not sufficient for young people to fully develop competencies, such 

    as sport accomplishments, playing instruments and artistic abilities. To have an activity 

    benefiting a person's health, the requirements is to gradually develop the person's abilities 

    based on active learning, engage in various types of exercises and have clear goals. The 

    school's activities do not have this kind of structure and it is therefore important that 

    young people have the opportunity outside of school and in the very neighborhood. 

     

    How can you precede the work of involving the youth in the spatial planning? 

    In real practice, the young people’s influence is not included during the whole planning 

    stage, only in the very beginning. This is considered as manipulation. To fulfill the co- 

    degree of influence, it requires that young people are involved and enthused through the 

    implementing-, planning- and management stage. The best way to capture young people's 

    thoughts, ideas and experiences is to use methods such as recreational centers, mental- 

    maps, walking trips or internet communication.

    Integrerat brounderhåll2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Trafikverket is responsible for the public traffic network in Sweden. The traffic

    network contains around 15 500 bridges that constantly are exposed of different

    kinds of degradation. The bridges must therefore be maintained at regular

    intervals both to keep bridges in good condition and to prevent the degradation

    accelerated.

    During the last years Trafikverket has developed a new procurement method of

    bridge maintenance. The method involves that all bridges maintenance of a region

    is being bundled to one contract that an entrepreneur handles for five years, a socalled

    bridge maintenance package. A bridge maintenance package exists of

    preventive maintenance, remedial maintenance and emergency maintenance.

    The purpose of this paper is to follow up the new form to procure bridge

    maintenance in package. The goal is to clarify the gains or losses made in

    efficiency since the introduction of bridge maintenance in package.

    Methods used in the creating of this thesis are literary studies, meetings and

    interviews along with analysis, calculations and comparisons.

    The result lays the foundation for the client, contractor and consultant working in

    the bridge maintenance package and further what has changed from the way they

    were working on bridge maintenance earlier.

    The largest efficiency gains are administrative. Because a bridge maintenance

    package is a turnkey contract the majority of responsibility is put on the

    contractor, instead of the client, which gives the client time for other tasks.

    Nowadays the bridge maintenance is in a separate contract which lasts for a longer

    time which gives the client a more qualified contractor for that kind of work

    which is reducing the number of fundamental questions and gives the client extra

    time. The contractor will get more operating freedom and at the same time more

    time to plan maintenance work. Through frequent communication between client

    and contractor decision-making paths becomes shorter which gives more

    efficiency throughout the entire process.

    The package in the region Skaraborg was one of the first bridge maintenance

    packages and it differs a lot from later maintenance packages. The biggest

    difference is in the contract documents. The package in Skaraborg was based on a

    fictional bridge while the more recent maintenance packages documents addresses

    the real action which the contractor will perform during the contracted period.

    Abstract [en]

    Purpose: In Sweden, a municipal plan monopoly is used to regulate what, how and where you can or cannot build. How the plans, in the shape of comprehensive and detailed development plans, are formed is in turn regulated by the Planning and Building Act (PBL). Throughout history, Swedish building regulations have gone through many more or less extensive changes with the overall goal to improve our built environment and simplify or streamline the planning and building processes. From this comes the term small deviation, which in PBL is used to allow building permits that deviate from the detailed development plan, provided that the deviation is small. There is, however, no explanation in the law as to what this might mean in practice, and so there are large differences in terms of interpretation and application.

    The goal of this study is to analyse how the term small deviation according to PBL, chapter 9 § 31b is interpreted and applicated in building permit trials.

    Method: The methods used in this study are interviews (with building permit officers) and document analysis (of building permit decisions from quarter two, 2016, and court cases from the Land and Environment Court of Appeal).

    Findings: How deviations are interpreted does indeed vastly differ, and while the municipalities do work in a similar manner to determine whether a deviation could be considered small, there are significant differences. Only in the matter of built area on a property, the three studied municipalities all have different practices in what size of violation may be considered small, and the building permit officers in one of these municipalities still deviate from this. In eight out of 13 court cases, the Land and Environment Court of Appeal judged differently from the previous authorities. Only in one did all authorities agree.

    Implications: The findings implicate the following:

    • There are remarkable differences in how small deviation is assessed.

    • De biggest differences are between the local building permit officers and the Land and Environment Court of Appeal.

    • The factors that affect the assessment on a municipal level the most are experience, precedent cases and discussion with colleagues.

    Limitations: A wider study containing more information from several municipalities and an analysis of the material accessible to the municipalities for guidance to assess deviations would provide a clearer answer as to what affects the interpretation.

    Keywords: PBL, Planning and Building Act, building permits, law interpretation, interpretation, deviation, small deviation, deviation from detailed development plan, sensemaking, the Land and Environment Court of Appeal

    Tillgänglighet i flerbostadshus från 1990 till nutid: Analyser av projekt i Uddevalla2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The built environment should be accessible for everyone. A residence shall be functional without creating a handicap for people who have a disability from birth, caused by an accident or of old age. A residence that is accessible creates equal conditions for everyone.

    In this report the accessibility of newly built blocks of flats in Uddevalla city from 1990 until today are interpreted. One project that is yet to be built is interpreted and compared with the already existing projects. The apartments of seven projects have been analyzed according to today’s regulations of accessibility. The Swedish politics regarding disablement and a historical overview of the building regulations from the 1980’s till 2010 give the foundation of the analyses of the projects. One type-apartment in each project has been furnished to be able to interpret how the accessibility demands are fulfilled.

    In the study the conditions of the seven projects are different. Two of the projects, that have been built 8 years apart, are two-story apartment blocks. These projects separate from the other projects that are four-seven story apartment block buildings. One of the buildings has the concept of being able to keep living in and using the apartment when ageing. The four project that remains are all block of flats with 26-45 apartments each, with the difference of when they were built, or is going to be built.

    The result of how accessible the different apartments are in each project depends on how well thought-out the floor plan is. The oldest project is comparable to and even better than two of the younger projects when it comes to accessibility. A neutral hallway or accessing a bedroom from the living room is a recurring design that is found in five of the seven projects. In three of the projects a failing design or different building regulations causes the bathroom to fail the accessibility demands. The recurring center- to- center distance between the toilet and washbasin in each projects determines if the accessibility demands are achieved. When a kitchen, dining area and living room are in an open connection with each other they create practicability, but depending on the measurements of each space the accessibility demands can be fulfilled or shattered by collisions, created when furnishing.

    Abstract [en]

    More than half a million people in Sweden are affected by some sort of disability. During recreational activities in nature areas, these people might encounter difficulties such as inadequate accessibility. The Swedish society requires that all citizens should have the same possibilities. The purpose of this thesis is to improve the accessibility for people with disabilities. The aim is to examine occurring flaws in accessible nature reserves and suggest possible improvements.The questions that will be answered are as follows:• What flaws do accessible nature reserves have, and how do they affect the visitors?• What improvements can be made in nature reserves to increase accessibility?To answer the questions, a case study was done, where five different nature areas were visited. During the case study, various flaws in the accessibility were observed and analysed. Prior to the case study, requirements and scientific research regarding accessibility was studied. Using this, suggestions for improving the accessibility were made. . Most of the improvements that could be made in the studied nature reserves were presumed to be applicable in other nature reserves in Sweden.With the case study in mind, the accessibility was considered in need of various improvements. The accessibility was studied from three out of four of the Swedish disability association’s categories; physical, communicative, and informative accessibility. The flaws that were encountered in the studied areas were due to incorrect design, or insufficient maintenance. Most of the flaws could be corrected in simple ways, but the flaws that were due to incorrect design or planning would require more work. After the case study it was discovered that supposedly “accessible” trails, according to different websites, had varying levels of accessibility. An accessible recreational area will benefit all types of visitors, not only people with disabilities. It will be more convenient and enables visits with strollers. An area cannot be made accessible for all types of visitors, but can be made accessible for as many visitors as possible.

    Abstract [en]

    This report is written in cooperation with the Swedish National Road Administration South-Eastern Region in Jönköping. The report is a result of the evaluation to give an answer to the question about how well the function contract has been carried out on the E4 in Östergötlands and Jönköpings län. The evaluation is divided in two hard parameters and one soft.

    The Swedish National Road Administration is interested in knowing how the standard on the road have been changed during the functions period, which is the reason why the first hard parameter is considering road standard. To evaluate the standard there have been a comparison of values from measures taken every year on the current road stretch. The second hard parameter considers economy. The Swedish National Road Administration wants to know if there are any economic reasons to continue this sort of purchasing, which only contains requirements of functions. The third and last parameter contains experiences from each part of the function contract and what each part thinks about this kind of contract.

    The result of the research dealing road standard indicates a clear increase of standard ensuring roughness and road markings. In an economic point of view the function contract shows many benefits, one of them is that the Swedish National Road Administration South-Eastern Region has paid a smaller amount of money compared to the calculated cost of purchase the same measures in a traditional contract. Based on the answers from the interviews the overall opinion of the function contract is very good, from each part of the function contract.

    The final conclusion is that this kind of contract suits very well for this sort of project and that the Swedish National Road Administration South-Eastern Region should use this kind of contract for the E4 also in the future.

    Effektivisering av ekologisk dagvattenhantering i stadsmiljö2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the city of Jönköping problems with the irregular flow, erosions and transport of sediment materials are recurring in the brook Strömsbergsbäcken. The problems is somewhat caused by an increased flow of storm water in the brook, which leads to high flow peaks in some parts of the brook since the original furrow is not dimensioned for the increased amount of water. The purpose of this project work is to make ecological drainage management in urban environments with a high amount of storm water discharge more efficient. The objective with the report is to create valuable material of how to accomplish ecological drainage management in urban areas and that the report will be useful for future similar connections. To fulfill the objective, the following three questions have been designed as a significant part of the final project report:

    • How can the load on the general drainage system be reduced?
    • How can the pollution effects of storm water runoff in urban areas be reduced?
    • Which treatments are appropriate to enhance the ecological storm water management in Strömsbergsbäcken ?

    The methods that have been used to solve these questions are document- and literature studies, and also a case study.The thesis results shows that the storm water flows from four of the nine areas that has its outlets in Strömsbergsbäcken, need to be treated through some kind of a solution or method that delays the water flow. The treatment could be performed in the area, before the storm water reaches the storm water network, which leads to Strömsbergsbäcken. The storm water flows can also be reduced by treatments adjacent to the outlets in the brook, where the largest flow peaks occurs. For example an essential solution to decrease the flows in Strömsbergsbäcken is to reconstruct the old dam located near one of the outlets into a basin, which will delay the stormwater flows.

    Abstract [en]

    Safety in the construction industry has become a question of top priority in recent years. Despite a massive investment of time, money and knowledge, the occur-rence of fatal accidents in Sweden alone is around one a month.

    The purpose of this study is therefore to improve the safety on the construction site. By an examination of the role of the safety agents and their cooperation with the construction workers and supervisors as well as examine how safety agents can improve safety on the construction site, which is the goal of the study.

    Four questions were formulated based on the purpose and the goal of the study.

    The methods used to answer the questions were a questionnaire survey, multiple interviews, a literature review and a document analysis.

    The report describes the safety agent’s role as a complex one with many different tasks. The role of the safety agents is regulated in the health and safety law, but it can sometimes be difficult to interpret and the agents can therefore interpret their role differently. Some of the tasks and the rights that the law describes is the right to stop a dangerous task, and the right to affect the employer. The safety agents should also participate in the early planning and carrying out safety inspections.

    The surveys show that safety agent’s cooperation with both construction workers and supervisors worked well at the examined places. A major area for improve-ment is in the early planning, where the safety agents should participate, which they rarely do.

    To improve the safety on the construction site the safety agents can lead by exam-ple as role models in safety. They can also use their right to stop a dangerous task and their right to affect the employer to improve the safety.

    Creating a safe construction site requires that everyone works together. There should be a safety approach through the whole project, from the people who con-duct the early planning to the people involved in the production. Everyone must work actively to achieve a good working environment. The knowledge of the safe-ty agents should be used in all steps of the construction process, not just in the production.

    I rapporten behandlas cykelvägsproblematik. Detta främst ur cyklisternasperspektiv då rapporten fokuserar på deras problem i dagens svenska samhälle.Cykelnätet är underprioriterat och nya ansatser behövs för att lyfta denna viktigafråga. Målet och syftet med rapporten är att öka medvetenheten om bristerna icykelnätet, visa på lösningar som kan höja nätets standard och öka cyklandetsattraktion. Rapporten besvarar frågeställningarna: Vilka brister i den fysiskautformningen är vanliga i svenska tätorters cykelnät? Hur kan problemen lösas?Metoden som valts för att finna brister och problem i cykelnätet är en fallstudie itätorten Skara. Bristerna sammanställs, generaliseras och övergripande lösningarföreslås.Cyklister önskar snabba, trafikseparerade, kontinuerliga och säkra cykelvägar. Deviktigaste kvalitetsanspråken är trafiksäkerhet och trygghet, framkomlighet ochtillgänglighet, orienterbarhet och tydlighet, miljöskydd och kretsloppsanpassning,estetik och gestaltning, samt underhåll och vinterväghållning. Delen avcykelvägsutvecklingsprocessen som behandlas i rapporten är principutformningmed konsekvensbeskrivning. Många åtgärder för att lösa problemen i den fysiskutformning finns tillgängliga.De huvudsakliga bristerna som fanns i cykelnätet vid granskningen var: onödigahastighetsreglerande åtgärder, undermålig beläggning och underhåll, bristandekontinuitet, bristande överfarter och korsningar, saknade cykelvägar, samt saknadskyltning och orienteringsproblem.Felaktigt utförda hastighetsreglerande åtgärder innebär en onödig risk ochobehaglighet som ofta går att lösas med bättre fysisk planering och i vissa fall intebehövs. Det är viktigt att cykelnätet är komplett och kontinuerligt. För detta krävsgod planering och kunskaper om möjliga åtgärder för att kunna utföra kreativalösningar. Korsningar och passager innebär stora säkerhetsrisker som kan lösasmed bland annat kontrasterande beläggning, upphöjda övergångar,cirkulationsplats och planskild korsning. För att kunna utnyttja nätets fullakapacitet är en förutsättning att god skyltning och kartor finns tillgängliga somhålls uppdaterade.Cykelnätet kan utvecklas på många punkter. Det är viktigt att på politisk nivå vågasatsa mer pengar på den miljövänliga infrastrukturen. Trafikverket jobbar med attgenerera material till stöd för kommunernas planering. Samarbeten mellankommuner, övriga intressenter och framför allt andra länder är viktiga för ensnabb utveckling.

    Cyklisters situation på 2+1-vägar2006Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    In this report the situation for cyclists on 2+1-roads is analysed and studied. These

    roads are often the old 13-meter roads that have been changed into 2+1 to increase

    the security. Two road sections outside Motala in Sweden has been deep studied

    and analysed. The different parts in the planning process show how the progress

    goes. To begin with the change should be within the old 13 meters but after the

    pilot study was circulated for comments the result became a broadening to 13,75

    and 14,00 meters. These new broadth gave a wider roadside and a safer situation

    for cyclists.

    The reconstruction outside Motala is an unusual solution since broadthening of

    the road area rarely is done. The biggest reason to this broadthening is probably

    the cycle races Vätternrundan and Tjejvättern and all the practice that takes place

    before these events. The township of Motala wants to promote cycling in their

    municipality. This whish where probably an important factor during the

    commenting period.

    The rapport also analyses different control documents used in the planning

    process. These are VGU (Vägar och Gator Utformning) and Inriktningsdokument

    för 13-metersvägar inom Vägverket Region Sydöst.

    Ledarskap för ökad effektivitet i byggproduktion2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The population of Sweden is steadily increasing, which raises the need for new infrastructure and new buildings. To meet these demands the construction industry must become more efficient. According to several researchers, better leadership can be a part of accomplishing this. Discussions regarding leadership are mostly from the leaders’ perspective and usually the decisions about what kind of leadership is needed is made by the leaders themselves. Not very often do the followers get a chance to share their thoughts on what they need to become more efficient. Earlier research shows a correlation between motivation and efficiency. Therefore, this study attempt to find out what motivates construction workers.

    This study intended to examine what type of leadership construction workers think they need to become more efficient. The study’s aim was to contribute knowledge about how leadership can increase the efficiency on the construction site.

    Method: Two methods for data collection were used. A literary review based on effective leadership and interviews with construction workers about their thoughts on what type of leadership would increase their motivation and efficiency.

    Findings: This study has, by answering the research questions, contributed knowledge about how leadership can increase the efficiency on the construction site. The construction workers are of the opinion that their leaders have a big impact on their efficiency. The leaders’ knowledge and experience of the production phase as well as their ability to communicate and plan ahead were all seen as factor that affect their efficiency.

    The literary review for this study found 23 effective leadership traits. According to the construction workers the leadership skills that contribute the most to their motivation and efficiency are humility, relationship-management, and self-awareness.

    Connecting the construction workers responses to the efficient leadership theories showed that the most relevant theories for increasing the workers motivation and efficiency are Transformational and Servant Theory. The theory of Servant is the most relevant since it focuses on the followers.

    Implications: To increase the efficiency one must focus on the people in the industry. By changing the leadership based on the construction workers' opinions their efficiency can be increased. Therefore, it is recommended that leaders on the construction site work with the leadership theories Transformational and Servant and that they develop the effective leadership traits, especially the traits the construction workers find most important.

    Limitations: This study was limited to the leadership from the site supervisor to the construction workers. The focus was on what type of leadership the construction workers wanted to become more motivated and efficient. Furthermore, the study was limited to four leadership theories and effective leadership traits.

    Keywords: Efficiency, motivation, effective leadership traits, Contingency Theory, Transformational Theory, Transactional Theory, and Servant Theory.

    ARBETSLEDARROLLEN - UR ARBETSLEDARNAS PERSPEKTIV2012Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This bachelor thesis is intended to point out differences within the supervisors’ role and contribute in making the role more attractive. At present the information about how the supervisors’ perspective varies on the supervisors’ role and the introduction to it depending on work experience and education is unknown. Further it was investigated why the supervisors’ role is seen as an entrance to the building industry and how to develop the role to encourage the supervisors to stay longer within it.

    In the collection of data we have been interviewing supervisors and studying literature. In total we have interviewed 14 supervisors in the region of Jönköping and the result of the literature study has subsequently been used to substantiate the outcome of the interviews. The selection of interviewees was partly based on the supervisors’ work experience and educational level but consideration regarding sex and age was also taken.

    The result showed that the supervisors experience their role as a diverse, social and coordinating role and the main work involves staking, preparation for upcoming activities, answering questions and solving problems that occur. Furthermore it appeared that the supervisors’ role varies in work tasks as well as what is considered positive, negative and difficult. Moreover varies the role in the vision of the leadership and the experience of response from co-workers. Although it also appeared that the variations may not always depend on work experience and education level but also on the supervisors’ personality. The supervisors, who have experience from being craftsmen, were considered to have several advantages, for example concerning practical understanding, detecting inaccuracies and delays and that they more easily get accepted by the co-workers.

    The result indicated that the supervisors are experiencing their first months in the role differently depending on work experience and educational level. Most of them also believe that there are opportunities for improvement concerning the introduction period. The supervisors who have experience from being craftsmen felt prepared for the role to a greater extent than those supervisors who have an engineering degree. It were primarily those with an engineering degree who feel the need of a mentor but the majority of the supervisors reckons that if mentorship is to be used the mentor should be working at the same place as the supervisor.

    In addition, it was shown that the supervisors enjoy their role but the supervisors who have an engineering degree see the role as more attractive than those with a background as craftsmen. Possible enhancements mentioned were improved wage development, increasingly greater responsibility, better economic planning and more variation in the types of projects and tasks.

    The conclusions drawn were that the supervisors’ role varies in the aspect of the role itself and of the experience from the introduction period as well as that there are certain requests for mentorship and that there are opportunities to introduce changes which may make sure that the supervisors remain longer in their role.
