BIM forward design process
The BIM forward design process starts with the architectural major (generally, the architectural major first determines the floor elevation, axis network, main plane layout, and facade shape), and then other majors intervene and perform collaborative design based on the architectural professional model. At the same time, each professional BIM forward design also has its own specific processes and methods. The model of the architectural major is the basis for collaboration with other majors. Each major should also work closely with the architectural model to realize its usage functions, and achieve collaborative design with other majors while ensuring the existing design deepening process of this major.
Advantage
(1) Based on the three-dimensional visualized BIM model, designers can more fully control the design effect.
(2) Based on multi-professional three-dimensional BIM model collaborative design, it effectively improves the quality of professional cooperation.
(3) The two-dimensional and three-dimensional linkage and digital-analog linkage of BIM models can effectively reduce drawing errors and improve drawing quality.
(4) The forward design mode can completely solve the problem of "drawing and model consistency".
(5) Highly structured model information can achieve automatic review of compliance to a certain extent.
(6) Based on the design BIM model, more design results can be derived, such as visualization results and performance analysis results.
(7) The digitally delivered design BIM model can be applied in the construction and even operation and maintenance phases, which is also the future development direction.
(8) The statistical results of engineering quantities can be carried out to increase the added value of the design.
Architectural professional BIM forward design process:
The architecture major is the "leading major" and closely cooperates with all other majors, so its design process is relatively complex. The following is the conventional forward design process for the architectural profession to intervene starting from the plan. If the timing of BIM intervention in the actual project is different, you can refer to the adjustment:
In the planning stage, the floor elevations are established, the scheme model is established, the plane layout and facade modeling are refined, and various building performance simulations and analyzes are conducted based on the scheme BIM model to optimize the scheme.
The plan is finalized and the first stage of initial design is entered. Other majors are ready to intervene, and the architectural major determines the axis network.
Divide building components and structural components.
(If the building structure is collaborated in separate files, the structural components need to be split into independent structural models; if the building structure is still collaborated through a workset in a Revit file, the structural components need to be assigned to a dedicated workset. At this time, you should There are no structural beams yet)
The construction major initially determines the fire protection zones and marks the rooms
The mechanical and electrical major intervenes, creates a new file, links the construction model, copies the floor elevation and axis network of the architectural major through the copy/monitor function, sets the base map of each floor, and starts the professional design of the machine room layout and shaft requirements to the architectural major.
After structural calculation, structural beams are added, structural columns, walls, slabs, etc. are refined and adjusted, and the adjusted model is provided to various majors through links in real time.
Entering the second stage of initial design. The architecture major continues to conduct in-depth design of key items such as core walls, doors, windows, curtain walls, floor (elevator) elevators, and ramps.
Cooperate with the mechanical and electrical majors to adjust the plane of the machine room and shaft, and provide the adjusted model to each major through links in real time.
The mechanical and electrical major made suggestions for the location of fire hydrants, drainage ditches, floor drains, etc., and the architectural major made modeling
In addition to the continuous deepening of each part of the major, the construction major also needs to check the integrated models of each major at any time, control the net height and spatial effects, and coordinate each major to complete the preliminary pipeline synthesis based on the electromechanical main line.
Adjust the architectural model to its basic shape, produce preliminary design drawings such as horizontal, vertical, and cross-section plans, and complete the preliminary design.
In the construction drawing stage, the design of each detail will continue to be deepened, and at the same time, the mechanical and electrical major's funding for reserved holes will be coordinated and implemented.
Draw large-scale drawings of walls, core tubes, bathrooms, doors and windows, etc.
Continuously integrate models, control net height, coordinate all majors based on mechanical and electrical pipelines, and complete pipeline synthesis at the end
Complete construction drawing models and drawings
Structural professional BIM forward design process:
There is an obvious difference between the BIM forward design of the structural profession and other professions, that is, the BIM model is separated from the structural calculation model. Although the BIM model is theoretically consistent with the structural construction drawings, the construction drawings do not originate from the BIM model. Therefore, the BIM model’s contribution to the structural profession itself seems to be small, but more to “contribute to the overall professional coordination of the project.” The participation of structural professionals is crucial to BIM forward design. Most cooperation issues between professionals can be solved during the design stage, so later modifications, changes, on-site processing and other matters are also reduced. At the same time, it also significantly improves the design quality of the structural profession itself.
At this stage, the process of BIM forward design for structural professionals is roughly as follows:
After the architectural professional plan is determined, the structural components will be split into independent structural models or classified into structural work sets, depending on the collaboration mode determined in the planning stage.
According to the architectural plan drawings, the structural major uses structural software such as PKPM or YJK to establish calculation models and carry out structural system selection optimization and calculation analysis.
According to the calculation results, the structural BIM model is adjusted and provided to various majors for collaborative design.
In the preliminary design stage, the calculation model and BIM model must be adjusted according to the funding provided by other majors, and it is necessary to ensure that they are carried out simultaneously to avoid omissions.
Participate in preliminary comprehensive pipeline design, working with other disciplines to ensure clear height requirements are met.
In the construction drawing stage, continue to deepen the BIM model and refine the structural components in conjunction with the building walls and other parts.
The construction formwork drawings are formed based on the BIM model and ensure consistency with the construction drawings of structural beams, slabs and columns.
Enter the steel bar information into the structural components and draw the drawings according to the flat method.
Professional BIM forward design process for water supply, drainage and HVAC:
The BIM design application of the mechanical and electrical major has been quite mature in the past in terms of three-dimensional pipeline synthesis, so there is no need to pay too much attention to modeling. The focus is on professional settings, graphic expressions and cooperation with other majors.
The BIM forward design processes of the water supply and drainage major and the HVAC major are relatively similar, and can be roughly summarized as follows:
Split and organize new Revit projects according to the projects in the overall planning, link the civil engineering model and copy the floor elevation, axis network, etc. to the electromechanical Revit file through the copy/build function
Establish plan views for each floor, each electromechanical major and its sub-majors, and apply view templates respectively.
Various calculations were carried out based on the initial model of the building, and the requirements for the area and location of the pump room, tube well location, riser location, etc. were submitted to the architecture major through a new financing view in Revit and followed up for implementation.
After the building plan is stabilized, the professional equipment layout, pipeline routing, terminal design work, etc. will be carried out. In the preliminary design stage, only the supervisor model is established, participating in the preliminary pipeline comprehensive coordination, and determining the supervisor route.
In the construction drawing stage, improve the layout of branch pipes and terminals, and participate in the comprehensive coordination of pipelines in the construction drawing stage.
During the design process, collaboration with civil engineering, equipment and other majors can be carried out by raising funds for other majors through the funding view and linking the funding views of other majors to accept funding.
In the drawing stage, pipelines, equipment information, descriptions, etc. are marked in the drawing views of each major to form drawings, which are finally produced through PDF and exported to CAD.
BIM forward design process for electrical majors:
The electrical major is often the last major to accept funding from other majors. Therefore, its BM forward design process is slightly different from that of the plumbing and heating majors. A brief list is as follows:
Check the linked civil engineering model and capital raising information.
Predict the system, identify electrical-related machine rooms and provide funding to the construction profession.
During the preliminary design phase, the main route of the bridge is drawn.
Participate in preliminary design pipeline synthesis and review the main routing of the bridge.
During the construction drawing stage, we will accept funding from civil engineering, water supply and drainage, and HVAC majors.
Arrange terminal equipment.
Line connection.
