| Construction planning information is based upon the data required for cost estimation, scheduling, and cost control systems. Cross-functional data acquisition, sharing, and reuse are important challenges for the engineering and construction (E & C) industry. However, they have been largely ignored. The objectives of this research are to analyze the fundamental problems of data acquisition, sharing, and reuse in the current construction planning processes and to maximize data sharing and reuse. As a result, the author develops a data model for building projects, "A Collaborative Construction Planning Data Model." This model is based upon two new concepts, "Work Packaging Using Design Components" and "Top-Down Collaborative Construction Planning Data Acquisition." This model is implemented by developing a prototype system, "CM Planner," for engineering, procurement, and construction (EPC) firms. |
