Traditional methods of project introduction and construction technology disclosure often face challenges in interpreting complex drawings, leading to low efficiency. In contrast, BIM technology offers a 3D visualization that provides participants with a clearer and more intuitive understanding of their responsibilities and the steps required to complete them. By incorporating 4D models that include construction process management, it is possible to simulate construction plans and schedule site access for each phase, allowing for easier plan adjustments. Optimizing these combinations helps achieve the most efficient schedule. Based on this, personnel assignments and construction plans can be developed, with the timing of materials, workforce, and equipment arrivals carefully coordinated to avoid delays or rushed work. This approach enables the construction team to better monitor overall progress.
Since the BIM model integrates detailed information about the shape, size, and process requirements of all components, qualified project suppliers can prefabricate parts off-site according to this data. These prefabricated components are then transported to the site and installed as needed. Customized to meet engineering specifications and site requirements, these parts offer high applicability, reduce installation time, minimize on-site storage and processing space, improve space utilization, and ultimately help lower overall project costs.
When it comes to refined management, traditional methods struggle to quickly and accurately access engineering data, relying heavily on experience and often leading to resource wastage during construction. BIM technology allows managers to rapidly retrieve precise information, enabling them to develop accurate resource plans tailored to actual needs. This reduces waste, eases logistics and storage pressures, and promotes efficient project management.
In collaborative construction, all stakeholders update their professional models on a shared platform. Due to the interconnected nature of these models, updates automatically reflect on the overall project. This real-time information sharing allows all parties to access and utilize the latest data as needed, fostering effective collaboration. Upon project completion, the platform aggregates all information into a comprehensive as-built model, which serves as a valuable resource for the operations team during maintenance. Throughout the project lifecycle, BIM technology supports construction companies in controlling costs, monitoring progress, and ensuring quality. It also provides technical support for informed planning and orderly execution, helping achieve optimal economic outcomes.
Regarding quantity takeoff, traditional methods require manually matching attributes across multiple 2D drawing lines. Different construction elements involve varied calculation methods, making the process cumbersome and error-prone, with low efficiency and significant time consumption. BIM overcomes these challenges by linking the designed model with component attributes such as beams, slabs, and columns. Using this quantifiable data, quantity calculations can be automated, greatly enhancing both accuracy and speed.
During project settlement, BIM’s embedded process data effectively reduces disputes caused by conflicting settlement figures. High-quality design solutions and thorough model analyses minimize engineering changes, accelerate progress payments, and improve the efficiency of final settlements, saving both time and costs.
Throughout construction, numerous documents—including contracts, schedules, supply lists, and data files—accompany the model information like drawing parameters. Extracting necessary information from these documents can be labor-intensive, often leading to coordination and scheduling conflicts. BIM technology streamlines access to essential information for all parties, reducing communication difficulties, minimizing unnecessary blame-shifting, and lowering project risks.
