[0002] BIM model is a comprehensive management system based on digital three-dimensional model. It integrates various relevant information of construction projects into a building model database. It not only includes the geometric information of the building, but also covers non-geometric information such as material properties, component costs, construction progress, operation and maintenance, forming an integrated information resource library, providing a basis for collaborative work for all participants in the entire life cycle of the building.

[0060] The construction calculation unit and the data acquisition unit are connected to the data evaluation unit by circuits, the data evaluation unit is connected to the data coordination unit by circuits, and the data coordination unit is further connected to the data comparison unit by circuits.

[0061] The construction progress plan compiled in the construction calculation unit and the on-site construction progress in the data acquisition unit are transmitted to the data evaluation unit for comparison. The data evaluation unit then compares whether the construction plan is consistent with the on-site construction progress. If they are inconsistent, they are coordinated through the data coordination unit. Finally, the data comparison unit compares whether the total time required for the construction plan and the total time consumed for the on-site construction are the same, so as to determine whether the entire bridge construction progress is successfully completed within the planned time. If the on-site construction time is less than or equal to the time required by the construction plan, the entire bridge construction progress is successfully completed. If the on-site construction time is greater than the time required by the construction plan, the entire bridge construction progress is not successfully completed.

[0062] In addition, the respective operating procedures within the construction calculation unit, data acquisition unit, data evaluation unit, data coordination unit and data comparison unit are set according to the situation.

[0063] Example 2

[0064] Based on Example 1, Figure 2 The present embodiment provides a bridge construction progress management method based on a BIM model, comprising the following steps:

[0065] Step 1): Establish a construction plan; among them, prepare a construction schedule to clarify the specific construction tasks and construction goals of the construction personnel in each cycle (one week, one month or one quarter);

[0066] Step 2): Obtain the construction progress on site in cycles; obtain data on the number of construction personnel, technical level of construction personnel, work attitude of construction personnel, and construction quality in each cycle to ensure that the project can be completed according to the predetermined construction tasks and construction goals;

[0067] Step 3): Compare the construction plan and the on-site construction progress; wherein, according to the comparison, establish a progress reward mechanism; wherein, in step 3), according to the comparison, establish a progress reward mechanism, reward the construction personnel who complete the construction task on time or ahead of schedule, and warn the construction personnel who delay the construction period. The comparison of step 3) can be set according to the program inside the data evaluation module;

[0068] Step 4): Establish a construction progress coordination mechanism for each cycle, clarify the construction tasks and construction goals of each construction personnel in the construction progress of each cycle, and facilitate the coordination of the construction progress of each cycle;

[0070] Among them, in step 5), the on-site construction time and the time required by the construction plan are judged. If the on-site construction time is less than or equal to the time required by the construction plan, the entire bridge construction progress is successfully completed. If the on-site construction time is greater than the time required by the construction plan, the entire bridge construction progress is not successfully completed.

[0071] Example 3

[0080] In formula (1), , and They represent weekly time periods (i.e. how many days a week there are), monthly time periods (i.e. how many days a month there are), and quarterly time periods (i.e. how many days a quarter there are). To distinguish the time section, , and Distinguish the weekly time periods Monthly time festival and quarterly time , that is, to distinguish between weekly time festivals Monthly time festival and quarterly time ;

[0081] Execute command for time section selection, Ability to select weekly time periods Monthly time festival and quarterly time Any time period in

[0082] For weekly time Monthly time festival and quarterly time Set the time of each session (i.e. set the specific number of days per week, set the specific number of days per month, and set the specific number of days per quarter), and then select the specific number of days per week from the weekly time session. Monthly time festival or quarterly time period Select a time node from any time node in For weekly time Monthly time festival and quarterly time The setting function of A selected time section.

[0083] From formula (1), it can be known that the construction progress can be intelligently obtained at a certain time node in a weekly, monthly or quarterly period by setting a weekly, monthly or quarterly time. For example, the construction progress can be obtained on a weekly, monthly or quarterly basis.

[0084] Furthermore, the target data node method is used to obtain the construction progress data. The data target node method is as follows:

[0085] (2);
