The application of BIM technology in construction can be primarily observed in the following key areas:
(1) Cost Management
1) Quantity and Price Calculation: During the construction phase, BIM enhances the efficiency of quantity takeoffs and pricing. Leveraging BIM’s parameterization capabilities, contractors can quickly and accurately verify the quantities of completed work. Based on the project’s progress, cost information can be retrieved directly from the BIM database to summarize the stage-wise project costs. This significantly improves cost management efficiency during construction.
2) Engineering Change Management: Construction projects often face extended timelines and unpredictable factors, leading to inevitable engineering changes. The BIM model integrates a correlation and sharing system, allowing project managers to update related data immediately upon changes. This enables timely adjustments in costs based on the revised quantities, helping to minimize deviations between actual and target costs.
(2) Progress Management
BIM technology allows for simulation and analysis of data throughout various stages of construction, helping to allocate human resources, machinery, and site assets effectively. Progress management using BIM integrates 3D parameterized models with project schedules to create BIM4D models. These models enable real-time comparison and analysis of actual site progress against planned timelines, facilitating precise control over construction schedules.
(3) Quality Management
BIM embeds detailed information such as scale and materials of building components within the model, assisting quality control personnel in overseeing the project. If non-compliant materials are used, BIM enables quick and accurate identification of affected components, allowing timely remediation. Additionally, BIM’s visualization capabilities help technicians guide construction processes by simulating operations in advance, identifying potential issues early, and preventing problems before they occur.
(4) Safety Management
Safety is a critical aspect of construction management. Despite numerous hazards on construction sites, many workers lack adequate safety awareness, and some companies neglect safety training, leading to frequent accidents. BIM technology helps identify potential hazards in advance, eliminate safety blind spots, and avoid accidents during construction. Furthermore, BIM provides visual tools for safety briefings, enhancing communication and awareness among workers.
