Effect of registration on performance of construction subcontractors in Singapore

Abstract

The construction industries of many countries rely heavily on subcontracting. As a result, the quality of subcontractors is important as it has a direct bearing on the performance of the main contractor on projects. A large proportion of construction work in Singapore is subcontracted. Despite the well‐known and widely regretted deficiencies in the traditional subcontracting system, only recently have attempts been made to reform it. The most significant of these efforts is the Singapore List of Trade Subcontractors (SLOTS). This study sought to investigate whether or not the performance of subcontractors has been improved following the introduction of the SLOTS scheme. The research was based on a survey of project managers of main contractors. A major finding was that the SLOTS‐registered contractors were perceived to perform better than nonregistered ones. Suggestions for improving the SLOTS scheme are offered in this paper.
