How to solve the problems of preliminary planning and design through BIM Technology, connect the information flow between design stage and construction stage, and solve the difficulties in construction stage are the key requirements of project management.
🔶  There are many subcontracts and it is difficult to manage.
On this basis, other units prepare BIM project guidelines, BIM schedule, implementation plan, management manual, bim5d application plan and other documents of each discipline to clearly guide the implementation of BIM work and responsibility implementation of the project.
Field problems are archived through the built-in problem library of the platform, and common problems are obtained through data analysis.
For example, in the project planning stage, based on the planning requirements of construction land, the design unit uses BIM Technology to plan and simulate the building itself and its surrounding environment, so that the design results can meet the traffic requirements, building form requirements, public supporting facilities configuration requirements, fire protection requirements, etc.
