Application of BIM technology in supervision project work

1. General idea

1. Management philosophy of supervision work

(1) Quality control: deepening of complex nodes and animation simulation of on-site construction.

(2) Safety management: edge protection statistics, edge protection and high-altitude operation safety warning animations, hazard source identification, and assistance in normalized safety management.

(3) Auxiliary communication: regular work meetings; visual construction briefings.

(4) Progress control: progress backfill, comparison of plan and actual, weekly task release.

2. Overall application program

(1) Implement the “one model” concept and smoothly transition from design BIM to construction BIM.

(2) Deepen the application of 3D models to avoid repeated modeling and maintain information transfer.

(3) Deepen it in conjunction with the needs of "4D progress control" and "guidance of construction".

(4) Actively explore 5D applications and development and try primary applications.

2. Technical preparation

1. Clarify the responsibilities of all parties involved in the project

(1) Owner: Proficient in model browsing, query, annotation and other functions; implement daily work application of BIM technology (regular construction meetings, progress control, construction quality control).

(2) Consultant: technical support (training, participating in writing plans according to needs); participating in summarizing standards and processes.

(3) Construction: Maintain the BIM model to ensure consistency with reality; regular application of BIM: simulation of construction of important and difficult points; electromechanical deepening to guide construction; review of changes...

(4) Supervision: organize regular BIM meetings every week, analyze and evaluate the implementation of BIM, and coordinate the work of various units in a timely manner; track the status of the model to ensure the authenticity and timeliness of the model and the site; be familiar with BIM technology and assist the owner in BIM implementation manage.

2. Improve the work system: release weekly supervision meeting tasks

3. Normalized management of BIM supervision

1. Review the depth of civil engineering model establishment

Build a professional model with an accuracy of LOD400, and check the model accuracy (created with Revit software). After checking some complex nodes such as stairs, building side elevations, and bathrooms in the civil engineering major, drawings will be produced.

2. The civil engineering professional 3D model is used for visual presentation by the project supervision department and review of the construction plan.

3. Use models combined with aerial photography technology to manage on-site layout

4. Review the in-depth establishment of electromechanical professional models

The mechanical and electrical professional model is built with a model accuracy of LOD400, and the model accuracy is checked to see if it meets the requirements.

5. Review and supervise the construction unit to model and use mobile devices to conduct on-site explanations

The construction unit is required to set up three-dimensional node diagrams and comprehensive pipeline diagrams in accordance with the drawing requirements to guide on-site construction and inspection and acceptance.

6. Require factory-supplied equipment to be incorporated into the model

7. Use collision detection to conduct comprehensive pipeline reviews, resolve on-site pipeline conflicts, and conduct on-site inspection and acceptance

8. Establish and review curtain wall models

9. BIM4D construction progress simulation analysis

After reviewing the progress plan, the WBS refinement task was issued. The detail of multiple floors and dozens of days was refined into the detail of a single floor and within a week. The construction unit is required to split the model according to the construction flow section and WBS.

Through simulation, it was discovered that the WBS preparation was unreasonable, and the construction unit was required to make reasonable modifications. The actual progress of the site is backfilled in a timely manner (model) every week, and Synchro is used to compare the construction progress plan.

4. Summary

Achievements: Civil engineering, electromechanical, steel structure, and curtain wall modeling reached LOD400, and detailed drawings were produced to guide construction on site. Visually and accurately guiding construction can reduce the chance of problems caused by structures colliding with each other. Through BIM technology, management efficiency and management processes have been optimized, comprehensive resource adjustment and program preview of the project have been completed, and considerable economic benefits have been achieved.

Disadvantages: In view of the wide range of electromechanical construction and the construction process and process requirements of many points, bottlenecks are encountered in the 4D simulation application process, making it relatively difficult to implement. The application of BIM5D is generally difficult, and it is still limited to monthly progress payment reports for concrete, large electromechanical pipelines, equipment, etc., while there is a lack of research on other majors and BIM, Internet of Things, and IFD library expansion.
