Step 102: associating the BIM model of the current task with the construction plan of the current task according to the mapping relation; the mapping relation is the mapping relation between the BIM and the construction plan; and the mapping relation is constructed according to the initial BIM model and the initial construction plan. In practical application, the BIM model is associated with a control plan (construction plan) according to the mapping relation, and the BIM model is uploaded to a BIM-based control platform, so that engineering implementation is known.
Further, the mapping relationship is constructed according to the initial BIM model and the initial construction plan, and specifically includes:
and acquiring an initial BIM model and an initial construction plan.
Decomposing the initial BIM model into a plurality of components.
Decomposing the initial construction plan into a plurality of inspection lots.
And associating the component with the inspection batch by using the task number to obtain a mapping relation.
In actual application, a mapping relationship is constructed, as shown in fig. 3. The method comprises the steps of carrying out model decomposition on a BIM model, decomposing the BIM model into a floor and a professional system, obtaining a plurality of members according to the floor and the professional system, carrying out engineering decomposition on an engineering entity, sequentially decomposing the engineering entity into unit engineering, subsection engineering and project division, finally obtaining a plurality of inspection batches, and associating the members with the inspection batches through task numbers. One task may correspond to 1 to n inspection lots, such as: 1 cast-in-situ bored pile task corresponds to 1 pile foundation inspection lot, and 1 concrete structure task corresponds to 5 inspection lots of a template, a reinforcing steel bar, prestress, concrete pouring and cast-in-situ structure; one task may correspond to 1 to n members, for example, 1 bored pile task corresponds to 1 pile foundation member, and 1 concrete structure task corresponds to a plurality of floors, beams, and columns.

The model component information change comprises component design parameter modification, component addition, component deletion, component combination model group and component model group splitting.
Wherein, the modification of the component design parameters comprises the change of positioning information, system information and technical information. If the identity information changes, the change is classified as the deletion and the addition of one component of the original component.
The newly added component is a component which is newly added with unique identity information; deleting the component, namely deleting the unique identity information; the component combination model group is to combine a plurality of components with unique identity information into a new model group with unique identity information, and the unique identity information of each component before combination needs to be deleted; the component model group splitting is to split a component model group with unique identity information into a plurality of components with unique identity information, the unique identity information of the split model group needs to be deleted, and the unique identity information of each split component is newly added; the addition and the reduction of the components in the model group only affect the design parameters of the model group and do not affect the unique identity information.
Further, the step 104 specifically includes:
and if the change condition is the modification of the component design parameters, not updating the construction plan of the current task.
And if the changed condition is a new component, adding a plan associated with the new component in the construction plan of the current task according to the mapping relation, or associating the new component to the existing construction plan.

And if the change condition is that the component model group is split, deleting the plan associated with the model group from the construction plan of the current task according to the mapping relation, adding the plan associated with the split component, or associating the split component to the existing construction plan.
In practical application, the attributes of the changed BIM model are extracted and then updated to the construction plan. Specifically, the component which has not changed the unique identity information inherits the original plan attribute. The change of the unique identity information occurs: the method comprises the following steps: (1) adding a new component, and adding unique identity information of an unallocated plan; (2) deleting the component, and deleting the plan associated with the component represented by the unique identity information in the construction plan; (3) the model group is combined, the unique identity information of each component before combination is deleted in the plan, and the unique identity information of the model group to be distributed is newly added; (4) and (3) component model group splitting: and deleting the unique identity information of the model group before splitting in the plan, and adding the unique identity information of each component to be distributed.
Step 105: and if the construction plan of the current task changes, updating the BIM model of the current task through a BIM-based control platform according to the changed construction plan and the mapping relation. The change condition of the construction plan of the current task comprises a plan time change and a plan content change; the plan content change comprises an addition plan, a deletion plan and construction content change contained in the plans.
Further, the step 105 specifically includes:
and if the change condition is the plan time change, updating the component time attribute associated with the plan of the time change in the BIM model of the current task through a BIM-based control platform according to the mapping relation.
And if the change condition is a new added plan, adding a member related to the new added plan in the BIM model of the current task through a BIM-based control platform according to the mapping relation.
And if the change condition is a deletion plan, releasing a component associated with the deletion plan into an empty task in the BIM model of the current task through a BIM-based control platform according to the mapping relation.
And if the change situation is the change of the construction content contained in the plan, deleting the components related to the construction content contained in the plan before the change in the BIM model of the current task according to the mapping relation, and adding the components related to the construction content contained in the plan after the change.
In practical applications, the planning time is changed only by adjusting the planning time, and the attribute of the BIM model can be changed accordingly. The changes in the plan content include addition plans, deletion plans, and changes in the construction content included in the plans. The newly added plans can be automatically associated only by hanging the members of the BIM model to the construction plan; after the plan is deleted, all components related to the plan are automatically released; the change of construction content contained in the plan requires that the original components not in the new plan are deleted, the newly added components are hooked, and the original components are reserved. The updating of the construction plan in the BIM model can be realized.
Step 106: and guiding engineering construction according to the updated construction plan or the changed construction plan. And forming a completion BIM (completion model) and control data until completion of the project, and storing the completion BIM and the control data into a completion file.
And if the BIM model is not changed and the construction plan is not changed, guiding engineering construction according to the BIM model of the current task and the construction plan of the current task.
