In the embodiment, the engineering construction progress plan management and control method based on the BIM model; the BIM model management and control system is used for carrying out BIM coding, BIM model management and control, BIM plan generation, BIM progress feedback, BIM progress simulation and plan correction; referring to fig. 1, the method comprises the following steps:
s1, establishing a unified BIM coding standard;
referring to table 1, the unified BIM coding standard includes project information, workshop information, service information, professional information, spatial region information, floor information, category information, device coding information, and the like.
TABLE 1 base Material Properties and product Properties
For within a BIM model, a model building block code may be represented as: XXX.002.ER.BA.DB1.1F.PR.PR01
S2, building a BIM model
And building the three-dimensional model in BIM modeling software according to professional requirements and BIM standard specifications, and integrating the built three-dimensional model into a complete BIM model according to factories and workshops. The code standard information is automatically contained in each component, and when the component is clicked, the specific code classification data and the relevant attributes of the component can be looked up from the database.
S3 plan generation based on BIM model
The invention provides an attribution relation expression of a BIM (building information modeling) model attribute definition component in a planning task based on BIM coding parameters by combining the engineering construction characteristics so as to flexibly express the complex logic relation of the engineering construction task. The project construction plan tasks can be automatically generated according to the plan task affiliation relationship, and meanwhile, the model performs light mapping in the system, so that the one-to-one correspondence between construction and tasks is realized.
1) Defining a set T of tasks T ═ { T1, T2, … }; t is ═ v, w, s, d >, v refers to the version, w refers to whether the change is made, s refers to the task state, and d refers to the programming time; in the storage model, there are multiple records for a task, but there is only one valid tree structure for a plan instance in the case of versioning.
Referring to table 2, a task in the database includes two records, and the task attributes include a task code, a task name, a pre-task, a construction period, a weight, a project amount, a scheduled start time, a scheduled finish time, an actual start time, an actual finish time, and the like. The latest version and state (state 1, version number V2) are read at the time of task loading.
TABLE 2 planning of collaborative tasks
2) Definition task t-level representation method
And (3) determining a task attribute hierarchy association set according to the step 2 of the specification, wherein the task attribute hierarchy association set is used for quickly generating a plan table, a plan tree can be obtained through one-time query, and the problem of long time consumption of recursive operation is solved.
The method for representing the association set is as follows:
{x＝value|(S01,1),(S02,2),(S03,3),(Si,k))}(i,k>0)；
where X represents a specific class attribute, value is a value representing a given attribute value, SiIndicating the task code and k the hierarchy of tasks.
Referring to fig. 2, a task association set is sorted out according to an engineering construction management and control method and a task attribute hierarchy association method. For each BIM model, all sets are traversed and automatically collected under specific parent and child planning tasks.
S4 plan display and compilation based on BIM model
And (3) displaying the BIM model and the planning task by adopting a lightweight method. The BIM model can be browsed on a browser after being converted through light weight, and the planned task level relation and the content are displayed on the browser end (hereinafter referred to as a Web schedule) through a Web front-end development method. Because the BIM and the plan both contain the same task code (Si), the BIM can position the specific member ID according to the task number, and the database can position the specific plan task ID according to the task code, thereby realizing the mapping between the BIM and the plan task.
And the planning engineer adds corresponding logic association to the task at the browser end and formulates a planning start time and a planning completion time. The logic relation can be dragged and labeled on the BIM, and can also be a planned task connecting line on a Web plan table, and based on the mapping relation between the BIM and the planned tasks, the logic relation between the BIM data and the planned tasks is unified after the data is stored.
Referring to fig. 3, the BIM model and the planning task show effects on the browser, and the BIM model and the planning task can be linked. The plan editor edits the logical association on the interface, as well as the planning time.
S5, BIM model modification
The BIM model is changed to some extent due to various reasons, model components and attributes thereof are changed by adding, deleting and modifying, and the planning task needs to be readjusted. The planning task needs to obtain the latest data according to the BIM model component version number.
To facilitate the management and control of the planned task change, step S5 includes the following sub-steps:
s51, changing BIM model does not affect the existing planning task hierarchy
If the BIM model component is added, the change state is marked in the planning task table directly added according to the component coding attribute.
For example, a concrete column is added to a certain floor, and if the original scheduled task table does not have the task, the concrete column needs to be added to the scheduled task table when the task table is loaded.
If the BIM model component attribute is modified, the latest version number data is stored in the database, the project task table acquires the component attribute value of the latest version, such as engineering quantity and the like, and the change state is marked.
For example, the work load of a concrete column is modified on a certain floor, the task is in the original scheduling task table, the task logic relation and scheduling time are not influenced, the overall scheduling progress is only influenced, and the work load of the concrete column needs to be modified when the task table is loaded.
S52, changing and influencing planning task level of BIM model
If the BIM model component is deleted, the original hierarchy and task logic are changed, corresponding examination and approval processes need to be installed to carry out relevant adjustment on the planned task, and a change state is marked in the planned task.
Referring to fig. 4, when a task in the original planned task list is deleted, the related logic condition associated with the deleted task needs to be redefined to ensure the accurate planning, and the marking is performed on the interface (the deleted task is added, and a horizontal line is added).
S6, progress feedback and simulation
After plan editing is completed, the actual progress needs to be fed back in real time, and the project construction progress can be conveniently and comprehensively mastered by a plan management and control worker.
Preferably, the BIM progress feedback includes the following sub-steps:
and S61, acquiring an actual progress model of the engineering site by adopting BIM technical means, such as a 3D scanner, an unmanned aerial vehicle aerial photography and other technical means, comparing the actual progress model with the plan BIM model, calculating the actual completion percentage, and feeding the actual completion percentage back to the plan task list through an interface.
For example, after scanning a key workshop by a comes RTC360 scanner, a video is processed to generate a Revit model, and then the percentage of completion of each part is analyzed according to an algorithm.
And S62, calculating the actual completion progress according to the intelligent camera feedback picture of each site and a preset progress threshold value by adopting a computer deep learning (video algorithm), and feeding back the actual completion progress to the scheduled task list through an interface.
For example, the progress of the position of a floor in the marked picture is 30%, the progress of the specific equipment above the floor is 50%, the picture captured by the camera returns to the intelligent algorithm server, and the actual progress is calculated through deep learning.
And S63, feeding back by adopting the mobile APP terminal, generating a two-dimensional code or a record for each planned task, clicking on the APP terminal to confirm after the constructor finishes, and feeding back the data to the planned task database.
For example, an APP code scanning function is developed, a constructor or a patrol inspector performs code scanning feedback on the completion content, and the completion time automatically enters the database.
S7 plan progress simulation
And performing progress simulation by combining the BIM model and the planned progress data, simulating engineering construction, civil engineering, installation and the like in an exact time period, finding out planned tasks which are delayed and possibly over-timed by comparing planned time and actual progress, and marking different early warning colors on the BIM model from a component level. The reason is analyzed for the overdue tasks in the system, the plan is revised, and the final plan is ensured to be completed according to the reason.
Referring to fig. 5, the column represented by 2 will be indicated in red for severe overrun and the roof represented by 1 will be indicated in yellow for early warning. According to the progress simulation feedback result, the engineering construction management and control personnel analyze the associated task logic from the system, find out the subjective and objective reasons influencing the task lag, adjust the task plan and ensure that the task is finished finally.

The plan is then revised to ensure that the final plan is completed as it is.
For example, an overdue for a planned task may be due to design errors, quality issues with procurement equipment, delays in logistics delivery, or other associated task delays, such as a delay in compliance with a piece of equipment, or may be due to a lack of compliance with the equipment infrastructure. Thereby starting to solve the problem from the source of the delay of the planning task.
