In recent years, BIM technology has been favored by the public. The use of BIM technology can support and improve many business practices in the architectural design and construction process, and solve more complex problems in the construction process. It is indispensable to owners, design units, and construction parties. Benefits of substitution. Today I will bring you the Category II results of excellent BIM technology application in Tianjin construction projects - BIM technology application in Tencent Tianjin High-tech Cloud Data Center project.
Project Overview
This project is located in Tianjin Binhai High-tech Zone, adjacent to Huixian Road to the north, Tianhuan East Road to the west, Shenzhou Avenue to the south, and Gaoxin 8th Road to the east, with a total construction area of approximately 144,800 square meters. The steel structure project includes a total of 8 single workshops from 1# to 8#. Among them, the structural form of factory buildings 1#~4# is a steel frame structure, with a total height of a single factory building of 23.66m, and a construction area of approximately 20,000 square meters; the structural form of factory buildings 5#~8# is a portal steel frame, with a total height of a single factory building. It is 9.94m, with a construction area of approximately 12,700 square meters.
Major and difficult points of the project
First, there are many intersections of professions. There are many intersections between steel structure engineering and civil engineering, mechanical and electrical, curtain wall and other professional work, and there are many collisions. The owner requires high installation accuracy.
The wall purlins conflict with the wall panels
Secondly, the construction schedule is tight, and 8 steel structure units are constructed in parallel. After reversing the construction period, the steel structure major needs to complete the construction of the main structure and envelope structure within 85 days. Resource organization is the difficult part.
During the design and construction phase,
1 construction floor plan
was used to carry out forward design of the construction site layout through BIM. By simulating the layout in advance and calculating the technical and economic indicators of various layout plans, in order to meet the basic requirements of the civilized construction regulations of the project department, The best solution to achieve less land occupation, less secondary transportation, and less temporary facilities was further optimized.
2BIM construction simulation technology
uses BIM technology to simulate on-site construction organization, on-site implementation and other stages. Construction simulation can discover problems in resource organization, technical solutions, safety measures, etc. in advance to guide project management to further optimize construction organization. , reduce project risks and provide effective support.
3 Drawing inspection
There are many professional interfaces related to large data centers. Using BIM technology, the interfaces between steel structures and other majors can be checked in advance to avoid conflicts and collisions with other majors. At the same time, the installation sequence and installability of steel structure components can also be checked in advance, and drawings with errors or omissions can be modified in a timely manner to help achieve rapid construction on site.
4 Progress Management (Visual Verification of Progress Plan)
uses BIM technology for progress management, which can effectively promote the integration of progress management and resource organization. According to the progress plan of the project site, the processing time, arrival time, installation time and other information of the relevant components are added to the BIM model, so that the on-site progress can be sensed and monitored in a timely manner and refined progress management can be achieved.
5 Quality Management
The BIM model contains not only material information such as component cross-section dimensions and material properties, but also process information for technical quality management such as installation requirements and process flow. The integration and "visualization" of the two types of information in the BIM model have been greatly improved. Improve the project management personnel's ability to control project quality.
6 Cost Management
uses BIM software to quickly generate an actual cost database, greatly reducing the workload of project managers in statistics, collection, and summary. In addition, cost data can be analyzed in multiple dimensions such as time and space to enhance cost control by project managers. ability.
Summary of application results
BIM technology produced the following results in this project:
1. Saving 17% of temporary construction costs and 20% of temporary land area through optimizing site layout design.
2. 17 late-stage risks were discovered through simulated construction simulation technology.
3. Drawing inspection found 36 errors, omissions and collisions in advance.
4. Save the construction period by 25 days and reduce the cost by 2 million.
5. Won the 2021 Tianjin Excellent BIM Technology Application Class II Achievements in Construction Projects.
