How does BIM transform the traditional construction change management?

The key to the application of BIM in construction change management is process reengineering, and zero change in construction is just a beautiful vision. However, it will be more valuable to change the change management process from the traditional low efficiency, long cycle and high cost to efficient, timely and dynamic cost control and orderly management.

Engineering change refers to the change of the project that has been formally put into construction. During the implementation of the project, according to the procedures agreed in the contract, some or all of the projects are changed in terms of materials, processes, functions, structure, dimensions, technical indicators, quantities and construction methods. Engineering changes are mainly engineering design changes, but changes in construction conditions and progress will also cause engineering changes.

Design change refers to the change and modification of the design standards expressed in the original construction drawing design documents by the design department.

Design changes and on-site visas are completely different in nature. On-site visa refers to the signing and certification made by the owner and contractor on the implementation of additional construction contents beyond the contract price during the construction of the project according to the contract. It is temporary and irregular, covering a wide range, such as design changes, concealed works, material substitution, changes in construction conditions and so on. It is one of the key factors that affect the project cost. Any kind of design change must be treated as a design change and cannot be solved by on-site visa.

First, the criteria for deciding whether to change.

1. Risks brought to the project by implementing changes;

2. Risks brought to the project by not implementing the change;

3. Impact of the implementation of the change on the project (schedule, cost and quality).

Second, the content of the engineering change

1, change the elevation, position and size of relevant parts of the project;

2. Increase or decrease the quantities agreed in the contract;

3, increase or decrease the project content agreed in the contract;

4. Change the quality, nature or type of the project;

5. Change huxing, building height, floor height, etc.

6. Change the construction sequence and progress of related projects;

7, engineering changes and technical disclosure put forward at the meeting of the blue prints.the design;

8. Complete any additional work required for the project.
