The possibility of using KM in construction projects has been analyzed in research projects such as Know Biz (P.M. Carrillo et al., 2003), CSanD (M.M.A. Khalfan, 2003), Clever (J.M. Kamara, 2002), e-Cognos (C. Limaet al., 2002), Klicon (T.J. McCarthy, 2000), and Capricon (C.E. Udeaja et al., 2008). Most KM research in the construction industry focuses on architecture, engineering and construction (AEC) rather than on sharing and disseminating research results, and no research has been carried out for specific construction subsectors such as underground construction.
