The construction industry is being challenged to be more innovative in
order to better satisfy the needs of clients and to enhance business competitiveness.
Off-site production (OSP) offers significant opportunities for achieving improvements
in process and productivity performance, especially in terms of delivering high
quality, defect-free construction. Indeed, OSP is increasingly seen as a key part of the
solution to improving the quality of construction and addressing skills constraints.
However, many industry stakeholders have not realised that OSP requires systematic
and strategic integration if these benefits are to be realised. In addition, many remain
sceptical of the potential of OSP technology, particularly given the past failings in
OSP practices. There is also an apparent lack of knowledge how to appropriately
integrate different OSP techniques into the design process. After reviewing the
concept of innovation, different levels of OSP techniques, and the current practices of
UK architects and designers, this paper explores the drivers and barriers inherent in
integrating OSP into the UK housing sector. This was examined through a range of
interviews with architects and other designers. The findings reveal that barriers to the
acceptance of OSP are centred around human perceptions grounded in the historical
failure of off-site practices to deliver improved performance, technical difficulties
(e.g. site specifics, delivery issues, interfacing problems, cost), lack of opportunities
for benefiting from economies of scale, and the fragmented structure of the
construction supply chain. This paper also discusses traditional and improved design
processes (DFMA) in which major changes in the design role and the composition of
the design team are called for. The findings of this study form part of a three-year ongoing
study which aims to explore the successful integration of OSP in the UK
housing sector
