Key points for civil engineering modeling: 1) modeling requires high-precision modeling.
At present, more and more projects are facing many challenges, such as complex construction process, tight construction period requirements, huge amount of information…
Key and difficult points of project construction (technical part) 1) the excavation depth of foundation pit and 1# floor core area pit is up to 9.00m, with high requirements for earthwork excavation and support; 2) The continuous concrete pouring volume of the bottom plate is 6700m ³、 High technical requirements for crack control of mass concrete; 3) The building height of the first # building is 149.90m, which requires high precision for the three-line control of construction setting out; 4) 2 ##.
6) The BIM team of the project shall periodically submit the results to the headquarters.
Hardware configuration (III) BIM application method 1.
Party A has very tight requirements for the construction period, and the project is positioned as a “Luban Award” and “national AAA standardized construction site”, with high engineering requirements.
▼ list of project services 2.
5) Project training system: The resident personnel of the project shall provide regular or irregular BIM technical training to the personnel of the project department.
3.
6) Formulate project implementation plan and scheme.
At present, there are still many problems in the application of Bim in construction enterprises: how can BIM be applied in the project? How to visualize the value of BIM? Today we recommend BIM project application cases.
2) Project staffing（ Select one person in charge among the resident personnel) preliminary stage: 2-3 civil BIM personnel (resident, according to the project situation) 1 commercial BIM personnel (semi resident mode) 1 Mechanical and electrical BIM personnel (not on site, tracking service) intermediate stage: 1-2 civil BIM personnel (on site, according to the project progress) 1 commercial BIM personnel (on-site service) 1 electromechanical BIM personnel (on-site service) later stage: 0-1 civil BIM personnel (semi on-site) 1 commercial BIM personnel (on-site service) 1-2 mechanical and electrical BIM personnel (on-site service) requirements: 1-2 personnel shall be arranged at each stage of the project to track the BIM Technology Application in the whole process and participate in the implementation of BIM Technology Application（ 4） Main application points of BIM implementation 1.
2) It is suggested that the modeler should professionally select personnel with practical experience as the modeling director, and the model construction personnel should regularly cross check the model, check and fill in the gaps, sort out the drawing problems, and use the model for field application after the compliance confirmation of the modeling director in the early stage of model delivery, so as to ensure the accuracy of the basic data of model engineering and help the fine management and control of the project.
Establish system guarantee company level system guarantee 1) weekly and monthly report system: The project leader shall submit BIM implementation results, BIM progress, application problems, next week and monthly implementation plans to the project department and the design institute every week and month.
Compared with the past, it can more intuitively present the project site layout, improve the communication efficiency, and effectively solve the difficult problems of project site layout, It is conducive to green construction and national standardized acceptance.
3 # building has many ultra-high, over span and over limit parts, of which the maximum span of steel beam of indoor basketball hall in 3 # building is 33.2m, which has high technical requirements for steel structure frame assembly and hoisting; 5) 1 # building large section column and inclined column of transfer floor have high requirements for formwork installation process; 6) The facade of the 1# building structure is changeable and presents a multi-level retraction form, with high requirements for the erection of external frames; 7) The facade of curtain wall is complex and requires high installation accuracy; 8) The basement area has complex structure, large volume, many electromechanical disciplines and complex pipeline direction, which requires high requirements for the accurate layout of machine room, channel pipeline and the installation of supports and hangers（ 2） BIM device configuration 1.
