Examination of Design-Assist Subcontracting

Abstract

The literature is absent a practical framework for understanding the effect of design-assist (D-A) subcontracting on project outcomes. This paper puts forth such a framework and develops an inventory of unresolved issues that should be addressed by academicians, industry groups, and practitioners. The D-A process pushes the architect and engineer in the direction of the construction manager and subcontractors, fostering a greater appreciation of construction means, methods, costing, and constructability. Likewise, the construction managers and subcontractors are pushed (or pulled) in the direction of the architect and engineer—resulting in the possible unintended assumption of design responsibility. Several thought-provoking questions are put forth vis-à-vis the use of D-A. Industry groups, insurers, and the legal community are called to awaken to this increasingly common practice of subcontracting. Practitioners benefit by gaining an understanding of the unanswered questions surrounding its use, in addition to the potential risks and benefits.
