The construction industry is struggling with declining productivity. As Sweden’s largest public-sector purchaser of constructions services, the Swedish Transport Administration launched a programme aimed at increasing productivity. One important component of this programme was the introduction of design-build procurement to increase the leeway provided to contractors to identify innovative and efficient solutions. In this case study of the programme, which focuses on design-build contracts, we have conducted 27 interviews with Swedish Transport Administration project managers, contractors, and consultants to examine how successful the implementation of some of these measures has been and what hurdles they have encountered.
