Engineering changes are an almost inevitable part of construction project implementation. They significantly impact project management, often causing delays, loss of investment control, increased rework, and reduced labor and machinery efficiency. How can BIM Technology be effectively applied across different stages of engineering changes to minimize losses or keep them within a controllable range?
1. BIM in Engineering Change Control during the Decision-Making Stage
During the decision-making phase, BIM plays a crucial role by providing feasibility studies that assess both technical and economic aspects of construction projects. This enhances the accuracy and reliability of study outcomes. BIM offers a comprehensive model that allows construction teams to analyze and simulate project plans, ultimately reducing costs, shortening construction timelines, and improving overall project quality.
2. BIM in Engineering Change Control during the Design Stage
Traditionally, design processes were fragmented and relied heavily on manual coordination and segmented communication. BIM technology revolutionizes this by enabling a collaborative, parallel interaction approach. Design involves multiple disciplines — including general layout, architecture, structural, plumbing, electrical, HVAC, power systems, as well as specialized subcontractors such as curtain walls, steel structures, intelligence systems, and landscaping.
Using BIM for comprehensive coordination significantly reduces design changes. Implementing BIM throughout the project involves:
- Developing project implementation plans based on specific project characteristics.
- Building BIM models for tasks such as modeling, quantity calculation, and cost estimation.
- Maintaining, updating, and providing data throughout the entire project management process.
- Managing rebar cutting and flipping operations.
- Conducting clash detection and settlement audits.
- Entering engineering data to establish BIM-based archives.
- Offering BIM-based technical data services, including on-site data support.
3. BIM in Engineering Change Control during the Construction Stage
In the construction phase, even when changes occur, sharing and managing BIM models enables effective oversight and dynamic control of design modifications. The virtual building model created by BIM serves as a comprehensive database containing all building information.
By integrating the 3D building model with time and cost data, a 4D virtual construction simulation can be created. This helps verify the feasibility of construction plans before actual work begins. Furthermore, it aids construction personnel in better understanding design intentions and project requirements, reducing errors caused by information miscommunication.
This approach breaks down information barriers, improves construction progress and quality, and allows real-time updates of the model in response to engineering changes. As a result, dynamic control and effective management of engineering changes are achieved.
How is BIM applied across various stages of engineering changes? As highlighted above, the widespread adoption and in-depth application of BIM Technology enable better control over engineering changes throughout the project lifecycle.
