Engineering change management refers to modifications made to projects that are already underway. Such changes are almost inevitable during the execution of construction projects and can significantly impact project management. They often cause delays, loss of investment control, increased rework, and reduced efficiency of labor and machinery. So, how is BIM applied in managing engineering changes? Let’s explore this topic.
Application of BIM in Engineering Change Control during the Decision-Making Stage
BIM plays a vital role in the decision-making phase by providing feasibility studies that assess the technical and economic aspects of construction projects. It enhances the accuracy and reliability of these studies. By offering a comprehensive model, BIM enables construction teams to analyze and simulate project plans effectively. This process helps reduce costs, shorten construction timelines, and improve overall project quality.
Application of BIM in Engineering Change Control during the Design Phase
BIM technology revolutionizes traditional, segmented design collaboration—which previously relied heavily on manual coordination and fragmented communication—by enabling parallel, interactive workflows. The design of a construction project involves multiple disciplines, including general layout, architecture, structural engineering, plumbing, electrical, HVAC, power systems, and specialized subcontractors such as curtain walls, grid structures, steel frameworks, intelligent systems, and landscaping.
Implementing BIM for comprehensive coordination significantly reduces design changes. Project teams can develop implementation plans tailored to specific project characteristics by building BIM models that cover modeling, quantity calculation, and cost data. Throughout the project management process, BIM supports maintenance, updates, and data provision. It also facilitates tasks such as rebar cutting and bending, clash detection, settlement auditing, and entering engineering data to establish BIM-based project archives. Moreover, BIM offers on-site data services and engineering technology data support.
Application of BIM in Engineering Change Control during the Construction Phase
During construction, when changes inevitably occur, sharing and managing BIM models enables effective oversight and dynamic control of design modifications. The virtual building model generated by BIM serves as a comprehensive database containing all building information. By integrating the 3D model with scheduling and cost data, a 4D virtual construction simulation can be created to assess the feasibility of construction plans before actual work begins.
This approach helps construction teams better understand design intent and project requirements, reducing errors caused by miscommunication. It breaks down information barriers, improves construction progress and quality, and allows real-time model updates to reflect engineering changes. This dynamic control ensures efficient management of engineering changes throughout construction.
In summary, while engineering changes can heavily impact construction projects, the effective and reasonable application of BIM in engineering change management allows many potential issues to be anticipated and minimizes losses to the greatest extent possible.
