ED - Pasquire, Chrisitne L. AB - Project delivery methods have tremendous influence over the amount of design changes and revisions realized during the course of construction. Studies have found that early collaboration with cross-functional teams during design can eliminate considerable waste during construction through impeccable coordination of the construction documents. However, the traditional design-bid-build approach has notoriously produced the opposite of that, that is, projects that result in numerous document revisions creating significant schedule delays and substantial variation to work flow. To counter the negative ramifications that this approach has during construction, the Last Planner System™ (LPS™) can provide a systematic methodology to improve reliability in an environment inundated with variation. The main hypothesis of this paper is that the use of the LPS™ can bring benefits to the planning process in design-bid-build projects and ultimately to its production trades. In order to deliver in 22 months an exceedingly unique 280,000 SF cast-in-place laboratory replacement project, which employed the traditional design-bid-build approach, the LPS™ was used. The LPS™ provided a structure to assist the team in improving planning on a project that had double the amount of revised drawings than the original bid set.
