Another important dispute factor is identified as variations in many dispute related studies (Watts and Scrivener, 1992;Heath et al, 1994;Bristow and Vasilopoulos, 1995;Kumaraswamy and Yogeswaran, 1998;Cheung et al, 2001;Chan and Suen, 2005b;Cheung et al, 2006;Love et al, 2010). Likewise, previous researches also revealed that any contradictory and error of information in the contract documents cause disputes between the parties (Bristow and Vasilopoulos, 1995;Fenn et al, 1997;Kumaraswamy and Yogeswaran, 1998;Mitropoulos and Howell, 2001;Cheung et al, 2006;Abeynayake, 2008).…”
