“…This new challenge has been given priority by the social actors (i.e., firms, institutional organizations, and researchers) of the construction industry. Some construction firms have been very keen in meeting this new challenge and have opted to develop and implement a "structured approach" (i.e., formal knowledge management systems) to manage their knowledge resources, whereas most construction firms have opted to adopt the "ad hoc approach" to manage their knowledge resources (Tan et al, 2010;Carrillo et al, 2004;Carrillo and Chinowsky, 2006). Several knowledge management techniques (i.e., lessons learned systems, post project reviews, communities of practices, training, forum, reassignment of people, mentoring) and technologies (i.e., groupware, expert directory, project extranet, podcasts social bookmarks, video sharing, social networks, blogs and micro-blogs) have been used by construction firms to acquire, disseminate, share, process and create new knowledge.…”
