A ROADMAP FOR INTEGRATION OF DESIGN-CONSTRUCTION DECISION MAKING

Abstract: It is a well-known fact that the design phase is fragmented from the construction phase primarily due to the differing insights of the two phases. In any construction project, the decisions in design take place without anticipating the constructability issues thereby resulting in changes, redesign, rework, errors, omissions, repetition or iteration. The ideal solution to overcome this issue is to integrate these two phases which are expected to be NP-Hard. Thus, the objective of the present study is to investigate an integration mechanism for construction projects. Integrated Project Delivery (IPD) is the recent buzz word in construction firms that has the potential features to integrate teams, processes and information. Although researchers had identified BIM (Building Information Modeling) as one of the potential IPD tools for addressing the design integration issues, still it is inadequate. Hence, in this study, two methods: point-based and set-based design are evaluated with the help of a hypothetical tall building design and construction case example. The pros and cons of these two approaches were also elaborated in this paper. A conceptual framework for integrating design and construction is proposed and challenges to implement Set-based design principles are discussed
