The construction sector in Sweden released 21% of the country’s CO2-e emissions in. With aggressive climate and pollution goals these emissions cannot be allowed to increase. There is therefore a need for more efficient construction methods and techniques in the Swedish construction sector. The construction sector is today split up between industrial construction and traditional construction. Industrial construction handles the construction process with a strong emphasis on the process and allocates all its efforts toward streamlining the process and removing wasteful steps and elements. Traditional construction places more focus on the individual project. It has one major advantage, which is its exceptional ability to adapt the specific project according to the wishes and demands of the customer and the project’s other unique circumstances. The IHB-model is the theory of industrial construction used in this study. This study seeks to find out which parts or mindsets from the IHB-model that can be applied to a traditional construction company, OF Bygg in Umeå, to increase its efficiency. This is done by studying the current use of industrial methods by OF Bygg, their views of industrial construction and comparing this to the IHB-model and looking at what parts can be applied to OF Bygg without fundamental shakeups in the company’s structure. The study of OF Bygg is mainly done through interviews with respondents from the company. During the interviews, a sense of general positivity towards industrial construction was given off by the respondents. It also became apparent that OF Bygg was partially industrialised in some areas, but that there remains big possibilities for improvement. Off-site manufacturing is used today in the shape of “field factories” and supply deals with industrial suppliers. Both of these are great industrialised methods and should be expanded upon whenever possible. Developed technical systems are used in most projects during certain stages. Efforts should be put into using these more extensively. ICT-tools are also used in most of OF Bygg’s areas but vertically integrating these tools further should be explored. Long term relations between OF Bygg and other market participants are rare since they’re considered detrimental to the health of the local market. Supply chain management is being handled through deals with logistics companies. OF Bygg could become their own logistics company with a centralised material warehouse to ease the logistics and enable use of JIT. Planning and control of the process is mostly handled through general project schedules. The Last Planner system alongside stricter routines is suggested. Customer focus is currently unnecessary for OF Bygg to bother with due to restrictions in the local market. Performance measurement and re-use of experience often get under prioritized often due to lack of time. The transfer of responsibility from the project or site management to a role specified to handle performance measurement and re-use of experience is encouraged.
