| Summary: | Despite increasing use of BIM and automation technologies in construction, reliable estimation and management of project costs is still a challenge for contractors. Although contractors are able to schedule and plan their project costs with the current estimating and planning tools during estimation stage, most analysis approaches that compare resource, sequence and method alternatives during pre-construction remain manual and based on experience. This limitation frequently causes contractors not to consider cost-efficient alternatives and even to lose a bid. Furthermore, the reasoning behind these decisions is not properly captured for use later in the project or future projects. Even with BIM use, 4D/5D tools primarily visualize the project with pre-determined cost and time information rather than using a simulation model. This paper shows a structured alternative comparison approach on a BIM and resource integrated discrete-event simulation platform (GSimX) to improve project cost analysis. With this approach, the simulation model on BIM helps compare possible crew, equipment, and other resource alternatives by time and cost while satisfying method, capacity, and spatial constraints. We demonstrate how contractors can improve pre-construction planning with structured pre-construction alternative evaluation on the geometry-integrated planning approach of GSimX. |
