With the advent of BIM modeling, a detailed 3D model can be created for every node of an entire project, accurately representing both primary and auxiliary materials for each component. Compared to traditional measurement methods, BIM offers a clear computational advantage. As housing installation and construction systems grow increasingly complex, with a rising number of items, project cost calculations become more intricate. This complexity often leads to overlooked cost items during estimation. Similarly, omissions during construction are common, causing costly and time-consuming rework. BIM’s quantitative calculation capabilities deliver fast and precise results, enabling thorough analytical checks. This makes it a vital tool for overall project management and progress tracking, helping relevant stakeholders strengthen investment control through BIM technology.
BIM technology provides a more accurate approach to investment control compared to traditional methods. Conventional engineering measurements rely heavily on manual calculations, numerous formulas, and on-site experience, resulting in slower and less precise outcomes. BIM distinguishes itself through its inherent metrological advantages, combining traditional flat measurement with visually intuitive 3D models. It automatically extracts the bill of quantities and applies corresponding pricing items, enabling a comprehensive project cost calculation based on drawings in a much shorter time frame. This efficiency is crucial for effective investment and schedule control.
During project execution, it is essential to compare and analyze cost data in near real-time alongside project progress. A key aspect of cost control involves the use of value engineering to evaluate three main cost types: budgeted cost, target cost, and actual cost. Timely problem identification and resolution prevent recurring issues, effectively managing the project’s total cost. By integrating BIM-generated cost data and corresponding cost attribute models, project teams can accurately analyze quantity limits and generate precise bills of quantities.
Currently, BIM technology is actively applied in civil engineering and installation sectors. In ongoing project management, the actual on-site workload is referenced to determine overall construction quantities. The collected data supports on-site construction management by providing detailed quantities for each project area. Project managers can access updated engineering quantity data in real time through the BIM information service platform, facilitating efficient data sharing. This comprehensive coverage throughout the project lifecycle enables effective responses and solutions for specific project management challenges.
