“…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.…”

Despite the reduction in cost and schedule, and the improvement of quality and safety, the design-build (DB) method in China’s civil aviation infrastructure projects (CAIPs) has not been widely used and not reached the full value. To know what the development expectation gap is,it is necessary to determine the disparity in developmental prospects of the DB method in China's CAIPs. To this end, this paper first conducted a survey to know what the development expectation is through 69 subjects working in CAIPs. After that, 25 cases data were collected to get the actual development of the DB in CAIPs.The key findings from the comparison between the expectation and actual development show that the design institutes play a leading role in the popular form of consortium in the DB mode, and the DB method is mainly used in CAIPs with small investment. In addition, this paper also analyzes how some causes contributed to the development gap and presents three strategical actions. This study not only shows the development status of the DB method in CAIPs, but also presents the reasons contributing the development expectation gap, along with the potential strategic actions, which can be as a reference for scholars and practitioners.
