Design-Build: How to Increase Its Usage and Its Impact on Architects and Contractors in Singapore

Abstract

The purpose of this paper is to explore the ways to increase the usage of design-build (DB). The scope covers how project managers (local and foreign) can play a role in increasing DB usage in Singapore. It is found that owners would adopt DB if their requirements can be properly met. This is achieved by having clear and comprehensive bid documents, having sketch designs prepared by client appointed consultants, and engaging experienced DB contractors. Clients also need to engage project managers and consultant quantity surveyors to manage the DB projects, but the liability for design rests on DB contractors. Clients want DB contractors to provide warranty for fitness for purpose. The conclusion is that clients welcome the use of DB if some concrete steps are taken to make it meet their needs better. This study also concludes that consulting and contracting companies welcome DB, as this procurement method does not have a significantly negative impact on them.
