Abstract [en]

The house building industry has been characterised as less productive compared to the manufacturing industry with numerous and challenging activities including a complex integration process. For the last 20 years, industrialised house building has gained increased research and industry attention and is identified as a potential way to improve the overall house building productivity. In the overall process, the design phase has been identified as the bottleneck with several disciplines which have to be coordinated to generate a design solution that meets various customer and market requirements. Many aspects of a building's performance depend on the decisions taken in the early design process. These decisions can have a substantial impact on the overall design, lead time, cost and quality of the final product. However, there are many other important factors which need to be considered by designers during the design phase. Less attention has been paid to the identification of these factors within the design phase of the industrialised house building. Thus, the main purpose of this paper is to identify challenges and outline the critical success factors to be considered in the design phase of the Swedish industrialised house building. Qualitative research was conducted in combination with literature reviews and multiple case studies linking three Swedish house building companies. Empirical data were gathered from 20 semi-structured interviews. The study identified common challenges in the house building industry and 20 critical factors that should be addressed in the design phase from both literature and practitioners view. The result shows that fixed production is crucial for identifying the critical factors rather than a building system. Also, many challenges identified from this study could be managed by developing a platform-based approach with support tools and methods for critical factors in the design phase.

Abstract [en]

Swedish house building companies currently face many challenges in terms of fluctuating market demand, need for flexible product offering, non-uniform governmental regulations, high costs, and long lead times. These challenges affect both internal and external efficiency of companies. Product platforms have been used for more than a decade in this industry to improve both internal and external efficiency. However, the industry is still criticized for its inefficient and costly process. Smart manufacturing has emerged as means to improve the efficiency of internal processes and the question is if and how smart manufacturing can complement and support product platforms in industrialized house building. The aim of this study is to explore the potential of smart manufacturing to complement and support product platforms in theory and practice in the context of industrialized house building. A literature review and a multiple case study were chosen to fulfill the study objective. In total fourteen semi-structured interviews were conducted in two timber house building companies. The data was analyzed within and across cases using four platform assets for categorization: components, processes, knowledge and relationships. The results show that the smart manufacturing technologies are in both theory and practice mainly supporting the process platform asset through developing vertical and horizontal IT systems integration, definition and digitalization of flexible building systems, and transferring explicit drafting and engineering knowledge into parametric modelling tools.

Abstract [en]

With a glulam-based post-beam building system, a variety of building solutions is offered on the market for multi-story buildings. The building system must be adaptable to the demands of each project. However, short lead-time, efficient manufacturing and assembly must be ensured. The use of product platforms has been acknowledged as an enabler to manage external (customer) and internal (production) efficiency. The building system cannot be locked to a set of standard components as a high level of customisation is required. A set of methods and tools is needed to support the design work and to ensure that solutions stay inside the boundaries of the platform definition. The aim of this work is to map the state-of-practice in the design phase for a glulam building system from a platform theory perspective and outline a path forward for applying a sustainable platform development in companies where a component-based product platform does not suffice. Empirical data were gathered from an on-going product platform development including interviews and document analysis. The results show the lack of definition in platform-based product development from a theoretical perspective and need for development of support methods for design that align with different production strategies
