The following document is an introduction to Building Offsite. Funded by the UK Commission for Employment and Skills (UKCES). The content was produced by an industry and academic collaboration of CCG (OSM), Stewart Milne Timber Systems, Edinburgh Napier University and Heriot Watt University in partnership with Architecture and Design Scotland (A+DS) (Figure 1). The wider UKCES project remit was to create a Scottish Offsite Construction HUB as a centre of expertise, responsible for defining and showcasing skills requirements and ensuring collaboration between professions. Following the success of the UKCES project, the HUB concept is to be taken forward by the Construction Scotland Innovation Centre (CSIC) to ensure companies across the industry have an understanding of the interaction between the principles of design, construction, manufacturing and engineering, and that they are all maintaining high standards. The CSIC Offsite HUB will continue to develop practical and interactive learning material to share sector-wide, applying the process developed via the project (Table 1), upskilling the workforce and creating high level training on managing and delivering offsite construction. This document provides a starting point for raising awareness of the principles of offsite construction among various stakeholders, in particular clients and designers. This was identified as a clear need through the project’s skills needs analysis.
