ProduktionBygg is a research program run by the departments of structural engineering and production and computer-aided design from Luleå University and avdelningaran of Product and Production Development and Civil and Environmental Engineering at Chalmers University of Technology together with NCC Construction, Lindbäcks Construction, BoKlok Housing and Peab.

The construction industry needs to find new production methods that increase efficiency, without compromising the flexibility of different buildings produced. Several Swedish construction company therefore wonder: how do we work to combine standardization and flexibility effectively? The solid industry has long worked with the standardization and repetition, but stands today inquiring into how to effectively produce more flexible in short series. Production Build aims to create a synergy between production areas in the construction and manufacturing industries to increase productivity in residential construction. The goal of Production Construction is to develop new construction production that balances flexibility and standardization in the Swedish building construction for increased quality and reduced construction costs. The program will develop the following new production methods that handle standardization and flexibility:

  • 3D printing of construction parts reduces manufacturing costs for special solutions. Material selection remains to inventory, but both concrete and wood pulp has great potential. The technique can be exportable to countries that need to build their housing stock in war-affected areas.
  • Robots on the construction project involves replacing the tasks that are environmentally and are heavy, and find information that may be located outside of normal working hours. The savings consist of an increased production rate and increased accuracy. A reduction in production time by 5% corresponds to a saving of about 2 million in a normal residential projects.
  • Geometry Assurance increases the final product perceived quality of the end customer. How to meet a variety of surfaces in an attractive way and how should materials be selected to enhance the sense of quality, but maintain production efficiency? Customer satisfaction generates minor complaints, fewer retakes and corrections, which reduces the total construction cost.
  • Big Data approach to environmental data for building materials and components leads to greater predictability in the planning phase of a building construction. The right choice of materials also depends on the production method that is linked to the material. The client can be an early indication as to the balance between production efficiency and environmental impact, leading to greater customer satisfaction and more precise control of the building project. The 20% of the cost of a construction project that is added in the preparation and planning controls the size of the entire final sum, therefore early stages crucial for good economy and green sustainability.

On the 26th of march 2015 ProduktionBygg organized the first annual Swedish day for Production in Construction. The current goal is to develop ProduktionBygg into a larger programme that can move on to step 2 of the VINNOVA initiative Challenge-driven Innovation. The application is due on the 31st of august 2015.
