“…The DB method has become increasingly common in the architecture, engineering, and construction industry (Everest & Malloy, 2000;Fathi & Shrestha, 2020;Gransberg & Senadheera, 1999;Jide, 2003;Toosi et al, 2019), and findings show the efficacy of DB in providing superior cost and schedule outcomes over the DBB method (Ameyaw, 2009;Franz et al, 2020;Goftar et al, 2015;Park & Kwak, 2017;Sanvido & Konchar, 1999). The airport construction is no exception (Gad et al, 2019;Noguchi et al, 2015;Rosner, 2008;Touran et al, 2009). Since 2020, runways and buildings in airport have been delivered by using the DB method in China; however, the limited applications do not reach its full value, and the development of the DB method in CAIPs falls far behind other industries.…”
