Abstract
Nominated Subcontractor (NSC) has been widely used to select subcontractors for construction project in Singapore. As taking into account Employer's requests, it is an useful subcontracting system. In our previous research, the unilateralism of NSC system among project participants has dealt with comparing standard contract forms. However, most of related researches are not clarified the actual condition of NSC system in Singapore. Thus, it is necessary to clarify the actual condition of NSC system.
This paper introduces the actual condition of the NSC system in Singapore. The questionnaire was conducted a survey of 34 Japanese experts and 18 building construction projects, executed by Japanese general contractors. In result, first the responsibility of NSC problem is distributed on all participants, but the distribution of responsibility is different in accordance with participant's roles and contact conditions. Second, the average ratio of NSC selection is calculated at 16.1%, but the actual ratio of each project is much different from average. Third, DSC has many advantages, in terms of management aspects such as quality, cost, time, with comparing NSC.
