“…In general, scholars have significantly explored the stages of design, bidding, logistics and construction. Particularly, the risk assessment of construction contracts (Kartam and Kartam, 2001;Zaghloul and Hartman, 2003;Haddad, 2007;Hameed and Woo, 2007), supplier-contractor collaboration (Bemelmans et al, 2013;Rahman et al, 2013) and approaches to determining the lower limit of the bid for a project (Chao and Liou, 2007) have been investigated extensively and thoroughly. In addition, some scholars have studied construction risk assessment from the perspectives of schedule (Nasir et al, 2003;Huang and Wang, 2009;Luu et al, 2009;Wang and Huang, 2009;Liu, 2011), quality (Ortega and Bisgaard, 2000;Andi and Minato, 2003) and safety (Hu et al, 2011;Wu et al, 2015;Zhou et al, 2015).…”
