“…The former can be described as factual, and is often embedded in "procedure manuals, organisation maps, work break-down structure, document management systems, collaborative intranets and extranets" (Dave & Koskela, 2009: page 894), whereas the latter is subjective, derived from individual experience and judgement, and is exchanged between people (Choo, 1998;Choo et al, 2000). Arenius et al (2003) argue that sharing both types is important for the successful outcome of the project, while others suggest that success and innovation in the Architecture, Engineering and Construction (AEC) industry depend on "on-the-job experience" (Dave & Koskela, 2009;Kamara et al, 2002;Styhre et al, 2006;Styhre & Gluch, 2010), and therefore, effective and efficient KE involves sharing of tacit knowledge. Hardwick et al (2013), and Schilling and Phelps (2007) suggest that trust enables the transition from exchanging codified and explicit knowledge to more contextualised tacit knowledge.…”
