BIM model verification points

On the premise of meeting the modeling accuracy standard requirements and model planning requirements, the following points should be paid attention to during the modeling process:

1) Professional structural modeling: It is required that the cross-sectional dimensions and positioning dimensions of beams, plates, and columns must be consistent with the drawings; if pipelines pass through beams, walls, or plates, the designer needs to provide detailed reinforcement drawings, and BIM will make them Reserve hole settings and nodes.

2) Architectural professional modeling: It is required that the dimensions, ceiling height, etc. of stairwells, elevator shafts, tube wells, distribution rooms, air-conditioning rooms, pump rooms, heat exchange station pipe corridors, etc. must be accurately positioned.

3) Water professional modeling requirements: the naming of each system must be consistent with the drawings; some water pipes that need to increase the slope must be built with slopes according to the drawings; various valves between systems must be added according to the positions in the drawings.

4) HVAC professional modeling requirements: The naming of each system is required to be consistent with the drawings; some equipment and ends that affect the pipeline integration must be built according to the drawings, such as fan coils, air outlets, etc.; HVAC water system modeling requirements are the same Water professional modeling requirements are consistent;

Comprehensive pipeline management and control requirements

1) Pipeline synthesis should be completed once in the construction drawing stage and in the construction professional deepening stage.

2) During the pipeline synthesis process at the construction drawing stage, the design unit and BIM consulting unit should collaborate closely and work together using BIM models. The design unit should adjust the two-dimensional drawings based on the three-dimensional situation reflected in the final BIM model.

3) The BIM pipeline synthesis in the professional deepening stage of construction should be carried out on the basis of the results of the design stage, and the pipeline models of relevant professional deepening should be added to optimize and adjust the contradictory parts. The professional detailed design unit should adjust the two-dimensional drawings according to the three-dimensional situation reflected in the final detailed BIM model.

4) During the pipeline synthesis process, if it is found that a certain system is prevalent and affects reasonable pipeline synthesis, it should be submitted to the design unit for review of the whole system design.

BIM model depth and information requirements at each stage

BIM model depth and information requirements in the design stage

Project design stage

In the scheme design stage, a BIM outline model is established, which contains geometric information of the building, structure, curtain wall facade, and site, and has the function of analyzing and statistics of the functional space of the building.

preliminary design stage

The preliminary design stage is the process between the scheme design stage and the construction drawing design stage, and is the stage where the scheme design is refined. During the preliminary design process of this project, communication, discussion, and decision-making can be carried out around the visual architectural model. The architectural model can be refined and improved, and the structural modeling can be used to verify the design. Use BIM software to establish a three-dimensional solid model, check the consistency of planes, elevations, and sections, cut the revised model, and generate large-scale drawings of planes, elevations, sections, and nodes to form buildings and structures in the preliminary design stage. Models and preliminary design 2D drawings. The detailed schedule generated by the BIM model can reflect the main technical and economic indicators of the construction project in a timely and dynamic manner, including the number of building floors, building height, total building area, various area indexes, number of residential units, number of rooms, number of parking spaces, etc. In order to achieve the goal of improving architectural and structural design plans, we provide BIM models and design basis for construction drawing design.

Construction drawing design stage

Construction drawing design is an important stage of construction project design and is the bridge between project design and construction. This stage mainly expresses the design intention and design results of the construction project through construction drawings, and serves as the basis for on-site construction production of the project. The BIM model in the construction drawing design stage is a complex process for each professional model to build and optimize the design. Information models for various majors include architecture, structure, water supply and drainage, HVAC, electrical and other majors.

BIM model depth and information requirements during construction phase

After receiving the BIM model from the design stage during the construction stage, the constructability should still be continuously checked and the BIM model should be continuously revised according to the on-site construction conditions. In addition, we continue to collect construction information in key construction areas and compile equipment manufacturer information, certificates, warranty times and other relevant data. This will facilitate the delivery of a complete record model after completion for subsequent development and application of the facility management platform.

Model depth and information requirements at the completion stage

Entering the completion stage, the model is revised to complete the completed version according to relevant completion drawings and information, which can assist the construction site in engineering inspection work and ensure that the construction party completes the construction project. Confirm the mechanical equipment with contract specifications, and import the brand, model, specification, supplier, agent, construction manufacturer, maintenance manufacturer and other information into the model, so that the information can be quickly checked during operation and maintenance.

Modeling specifications

architecture

General requirements

Modeling content: building walls, scattered masonry, doors, windows, steps, stairs, railings, handrails, ramps, elevators, escalators, parking spaces and accessories, floor openings, wall openings, rooms, drainage ditches

Modeling method

A. Use system families such as walls, slabs, stairs, railings, handrails, etc. to create models of building masonry walls, floor slab names, stair surfaces, railings, handrails, steps, etc.

B. The modeling of the waterproof layer must meet the following requirements:

a. Separate modeling of exterior wall waterproofing; b. The foundation floor waterproof cushion is modeled separately; c. If the engineering practices of bathrooms, roofs, etc. include waterproofing practices, use the following modeling method: Ground: According to the engineering practice, the ground surface layer is divided into three layers for modeling, that is, it is divided into three layers: waterproof lower layer, waterproof layer, and waterproof upper layer. The corresponding engineering practice is also divided. Wall According to the engineering practice, the wall surface layer is divided into three layers for modeling, that is, it is divided into three layers: waterproof lower layer, waterproof layer, and waterproof upper layer. The corresponding engineering practice is also divided. The following is an example of how to decorate the bathroom wall: The bathroom wall design is interior wall 18 and 19, so the walls here are divided into: Interior wall 18-face brick waterproof wall-20-waterproofing, including interior wall 18 practices 1~3 Interior wall 18-face brick waterproof wall-20-waterproof, including interior wall 18 method 4 Interior wall 18-face brick waterproof wall-20-under waterproofing, including interior wall 18 method 5 Note that the height of the wall waterproof layer model is 1800.

C. Create corresponding building component models using component families such as doors, windows, roller shutters, and elevators.

D. The drainage ditch of the building should be built using walls, boards or self-created families according to the method in the drawing. In addition, the ground surface layer with drainage ditches will not be sloped.

E. Create rooms for all functional spaces and label the room names. The functional spaces that need to be created include: tube wells, stairwells, equipment rooms, bathrooms, etc.

F. The equipment foundation is a structural member and is built in the structural model, but the surface layer of the equipment foundation is built in the architectural profession;

G. Parking spaces are modeled as a family, and parking spaces need to be numbered. Parking space lines of adjacent parking spaces should not be modeled repeatedly to avoid repeated calculation of calculation amounts;

H. The ramp is first modeled using the "Floor" function to facilitate the input of ramp construction method information;

I. Due to the part-based modeling of structural stairs, architectural stairs need to be modeled separately. The staircase model does not need to be stored separately and is saved with each floor.

Notice:

1. Due to cost calculation requirements, the stairwell is built according to the boundaries of the inner walls, and the stair number in the drawing is used as the room name.

2. The room should be closed.
