Policy makers in the UK and other parts of Europe are refocusing attention on early supplier involvement to increase levels of off-site, but there are few recent case studies. To understand the situation more clearly this research considers projects with standardised layouts where there are varying scenarios of supplier-driven and client-led designs. Off-site and on-site construction quantities are measured and compared with other quantitative and qualitative data to understand the conditions of their selection. In projects where the layouts were the most standardised with a highly commoditised brief, early supplier input did lead to a more economic off-site option being introduced. However, despite this early involvement, no clients chose to contract directly with a supplier. Further studies are needed, but it is believed that these conditions are not uncommon in the industry. Suppliers have significant barriers to overcome with existing commercial trends for design and build contracting and future research needs to focus on the actual scenarios encountered in practice to see how these conditions could be improved.
