Scale-up of configurator for mass customization of flexible single-family houses based on customer participation, digitized integrated collaboration from design, via building systems to construction

The construction sector currently has problems with low profitability, low productivity, high crime, high climate impact, poor working environment with a high proportion of occupational injuries and poor inequality why it needs to change and introduce new innovations.The idea behind this project is that flexible single-family houses should be made possible with predefined building components that can be configured with current customer and functional requirements and that are managed in a digitized design and production system.

The system means that the selected building system is connected to digital design and, by extension, automation via small-scale agile robotics.The results of the project include increased productivity, lower construction costs, higher freedom of choice, lower climate impact and safer, more gender-equal construction sites.The project is based on two basic hypotheses, firstly that digitalization provides the opportunity to improve customer participation, the quality of the built, the work environment and the efficiency of construction, and secondly that the fragmentation of the construction sector is a major obstacle to improvements.The digitalisation takes place in collaboration between industry and researchers at the Faculty of Engineering (LTH) and the Technical University of Denmark (DTU) and is based on the principles of mass customization, a rule-driven digital technology linked to the concept of Industry 4.0, is used in almost all other industries.Completed work within Formas project 2021–00334, ongoing work at DTU and within the Centre for Construction Robotics at LTH have used the business model in the construction of 16 single-family houses, which has also confirmed that the technology is also applicable useful in the construction sector.The aims of the continuation project are;provide conditions for innovation in the sector as inspiration and experience base for the sectorto verify that the technology is nationally and internationally scalable, with other materials and also to larger buildings and infrastructure.To streamline customer participation, design calculations, climate declarations in a life cycle perspective for a number of commercial applications.Certification of masonry robots according to the EU Machinery Directive is important as it currently prevents the commercial use of construction robotics.
