BIM technology has proven to be highly effective during both the design and construction phases of building projects, with particularly notable benefits in the construction phase. It helps ensure better control over project costs, schedules, and quality.
(1) Cost Management
1) Quantity and Price Calculation: During construction, BIM enhances the efficiency of quantity takeoffs and pricing. Thanks to BIM’s parametric capabilities, contractors can quickly and accurately verify the quantities of completed work. Based on this progress, cost data can be retrieved directly from the BIM database, enabling precise calculation of project costs at each stage. This approach significantly streamlines cost management during construction.
2) Managing Engineering Changes: Construction projects often face numerous unforeseen factors leading to changes. BIM models incorporate interconnected and shared data systems, so when changes occur, project managers simply update the relevant data. Costs are adjusted promptly based on revised quantities, helping minimize deviations between actual and target costs.
(2) Progress Management
BIM technology allows simulation and analysis of data from various construction stages to optimize the use of labor, equipment, and site resources, providing valuable insights for decision-making. Progress management through BIM integrates 3D parametric models with project schedules to create 4D BIM models. These models enable real-time comparison between actual site progress and planned timelines, facilitating detailed control over construction scheduling.
(3) Quality Management
Building component details such as size and materials can be embedded within the BIM model to support quality control efforts. If non-compliant materials are used, quality managers can quickly identify affected components using BIM and ensure timely rework. Additionally, BIM’s visualization capabilities assist technicians by simulating construction processes in advance, allowing potential issues to be detected and prevented before they occur on site.
(4) Safety Management
Safety is a critical aspect of construction management. Despite existing hazards on construction sites, many frontline workers lack adequate safety awareness, and some companies neglect safety training, leading to frequent accidents. BIM technology helps identify potential risks early, eliminate safety blind spots, and reduce accidents during construction. Furthermore, BIM provides visual tools for safety briefings, enhancing communication and awareness.
