Investigating the effect of initial scope establishment on the performance of a project through system dynamics modelling

摘要

Traditional construction procurement is generally used for projects with no unusual features and a well-established scope. In this method, work progresses sequentially because each step is completed before the next step is started. As such, making changes during construction is problematic and expensive. Design and build (D/B) method allows the client to introduce the contractor's design at any stage resulting in the possibility of having different levels of initial scope establishment. Consequently, the project can gain benefit through buildability and the integration of design and construction. The client's main criteria for selecting D/B procurement are to reduce the time and cost of projects through one point responsibility.
