Abstract:
Absent an overarching general model incorporating variables of activity resources, materials, and labor, as well as a clash detection and building visualization, large constructions projects are vulnerable to material waste and inefficiencies of resource allocation and the attendant risk of cost and time overruns.
Building information modeling (BIM) offers a powerful tool to tackle this project coordination problem. Despite the advantages of BIM, however, its implementation in project planning faces challenges due to the time-consuming manual process of entering parameters and updating models.
This research focuses on development of a method to create 4D models by BIM-based scheduling using constraint-based simulation. The proposed framework reduces manual work by using Iran national management standards as input data. This model also generates outputs of time, cost, material, and resources to enhance the quality of project plan. This model can produce the set of required resources based on financial constraints through a genetic algorithm process. This framework, therefore, may be used as a decision-making tool for project management or as a control tool during the construction period for updating the existing plan based on information gathered from construction operations and provides visualization data for external applications.
In this thesis, the literature related to the research subject will be reviewed, and the modeling method will be explained. The, capabilities of the proposed model and details of the modeling process will be demonstrated and described through a case study.
