Purpose: Several studies show that work motivation in a workplace affects the individual's ability to perform and this may result in construction errors such as unnecessary economical costs and additional work hours. The aim of this study is to investigate the link between construction errors and work motivation as well as its impact on the quality of an apartment building. Method: To complete the objective of this study literature studies, questionnaires and interviews were conducted. The literature study includes scientific articles, doctoral dissertations and encyclopedias. These are taken from, among other things, the university library databases. The surveys consist of 21 questions based on Herzberg's two-factor theory. The interviews are semi-structured and the questions are based on the results of the survey. Findings: The results show that the link between work motivation and construction errors depends on knowledge, experience, commitment, stress and time shortage, communication, chord, salary, benefits and lack of leadership. In the construction companies that were included in this study, there is a lack of motivation among professionals, and the reasons for this are mainly due to benefits from the company and chord wages. The building-related consequences that result from motivation decline prove to be economical and time-consuming. The economic consequences show huge error costs. The time suggests that errors and shortcomings in homes lead to additional working hours in order to correct the errors that occurred during the production period. Restrictions: The study includes ongoing housing projects in Jönköping where supervisors and occupational workers are current. Question one is generally answered when it is not considered corporate, as is the last question. Issue two, on the other hand, only applies to these investigated projects.
