Abstract

Constructability has been defined as the optimum integration of construction expertise at different development stages so as to accomplish the overall project goals. This implies that in the process of achieving constructability, a balance has to be struck among various client's requirements to avoid over-emphasis of one factor at the expense of others. In reality, however, it is not easy to arrive at an equilibrium position where constructability and other client expectations are optimally achieved. The obstacles are attributable to the imperceptible interlinking relationships amongst different client requirements. Added to these, the benefits of constructability are abstract and not directly measurable. The predominant culture and practice in the construction industry also resist changes that entail a more disciplined working approach. Whilst realising that contract consultants play a significant role in advising on suitable procurement methods, this paper explores the intricate effects of different procurement methods, such as Design-Bid-Build, Design and Build, Develop and Construct, Management Contracting, etc. on constructability, based on structured interviews with experienced contract advisors. Results show that early involvement of contractors in the design stage, allowing enough time for design and tender activities, undertaking a Constructability Review before tendering and ironing out discrepancies among design documents would enhance constructability.
