Description

Technical Field

[0001] The present application relates to the technical field of building construction progress management, and in particular to a construction progress management method and system based on BIM space ternary mapping. Background Art

[0002] In the construction progress management scenario, BIM technology has been widely used in progress planning. Existing solutions generally only associate the work breakdown structure (WBS) with BIM components to manage work progress. These existing solutions have many problems: First, the association relationship is static and one-way, which makes it difficult to adapt to dynamic changes in construction; second, the on-site progress feedback lags during the plan execution phase, which may lead to disconnections and conflicts between multi-level plans; third, when multiple teams work in the same space, the lack of dynamic verification of spatial topology logic can easily lead to spatial conflicts and process confusion. Currently, no effective solution has been proposed for the problem of how to improve the efficiency of construction progress management based on building information modeling in related technologies.

[0020] The present invention provides a construction progress management method based on BIM space ternary mapping. Figure 1 This is a flowchart of the steps of the construction progress management method based on BIM space ternary mapping according to an embodiment of the present application, such as Figure 1 As shown, the method includes the following steps: Step S102: Based on the component information of the BIM model, physical spaces with actual construction significance are divided and spatial topological logical relationships between the physical spaces are constructed; Step S102 specifically includes the following steps: Step S1021: parsing the BIM model in the BIM model library to extract component information of each model component in the BIM model, wherein the component information includes geometric information and non-geometric information; Step S1022: dividing the BIM model based on the component information of the model components to obtain a physical space with actual construction significance, wherein the physical space includes rooms, floor areas, and functional areas; Step S1023: constructing spatial topological logical relationships between physical spaces based on the component information of the model components, wherein the spatial topological logical relationships include adjacent relationships, inclusion relationships, and connectivity relationships.

[0021] It should be noted that Figure 2Schematic diagram of the structure of the BIM model according to the embodiment of the present application. Figure 2 As shown, in step S1021, it is necessary to import these BIM models in the BIM model library and parse them to accurately extract the geometric information and non-geometric information of all components (constituent entities) in the model, wherein the geometric information includes coordinates, size, and shape, and the non-geometric information includes type and system; Figure 2 As shown, in step S1022 and step S1023, the physical space with actual construction significance (such as Figure 2 In the example, space-001 and space-002 are represented by a physical space, including rooms, floor areas, functional areas, etc., and a topological logical relationship is established between the spaces, including adjacent, contained, connected, etc.

[0022] Step S104: constructing a ternary closed-loop mapping relationship between WBS construction tasks, BIM model components, and physical space based on the physical space and spatial topology logical relationship; Step S104 specifically includes the following steps: Step S1041: Bind each WBS construction task to at least one BIM model component using a preset matching rule to obtain a first mapping matching relationship; Specifically, in step S1041, the preset matching rules include component type matching rules and component coding rules; If the preset matching rule is a component type matching rule, the type of the required BIM model component is determined according to the work content and requirements of the WBS construction task, and then the corresponding BIM model component is matched from the BIM model according to the type and bound to obtain a first mapping matching relationship; If the preset matching rule is a component coding rule, a unique type code or component code is assigned to each BIM model component, and then the WBS construction task is bound to the corresponding component according to the code to obtain a first mapping matching relationship.

[0023] It should be noted that Table 1 is an example table for constructing a mapping between WBS and BIM model components according to an embodiment of the present application. For the binding of WBS construction tasks → BIM model components, each WBS task item is directly associated with one or more target components (as shown in Table 1, taking Revit modeling software as an example) through preset matching rules (such as component type matching rules and component coding rules). The preset matching rules include component type matching rules, component coding rules, etc., among which the component type matching rules refer to determining the type of required components based on the work content and requirements of the WBS task, and then matching the corresponding type of components from the BIM model; the component coding rules refer to assigning a unique type code or component code to each BIM component, and the WBS task item is directly associated with the corresponding component through the code. Through the binding method in step S1041, the precise association mapping between the WBS construction task and the BIM model component is achieved, ensuring the accuracy of the subsequent construction progress control using the ternary closed-loop mapping relationship.

[0024] Table 1

[0025] Step S1042: Based on the physical space and the spatial topological logical relationship, determine the BIM model components contained in each physical space to obtain a second mapping matching relationship; Specifically, step S1042 determines the BIM model components contained in each physical space based on the spatial topological logical relationship through the spatial inclusion relationship judgment algorithm, that is, the physical space is used as the geographical fence of the BIM model components to determine the BIM model components of each physical space and obtain the second mapping matching relationship.

[0026] It should be noted that for the attribution of physical space to BIM model components, each physical space determines the set of all BIM model components it contains through spatial topological logical relationships. Specifically, using the spatial topological logical relationships established above, the physical space is used as a geographic fence for BIM model components. The spatial inclusion relationship judgment algorithm is used to determine the BIM components contained in each physical space, thereby accurately determining the attribution relationship between physical space and BIM model components, ensuring the accuracy of subsequent construction progress control using the ternary closed-loop mapping relationship.

[0027] Step S1043: Based on the first mapping matching relationship and the second mapping matching relationship, a ternary closed-loop mapping relationship among the WBS construction task, the BIM model component, and the physical space is obtained.

[0028] It should be noted that Figure 3 is a schematic diagram of a ternary closed-loop mapping relationship according to an embodiment of the present application, such as Figure 3As shown, the first mapping matching relationship is the mapping matching relationship between WBS construction tasks and BIM model components, and the second mapping matching relationship is the mapping matching relationship between physical space and BIM model components. By using these two sets of mapping matching relationships, a ternary closed-loop mapping relationship between the three can be constructed: WBS construction tasks - BIM model components - physical space.

[0029] Step S106: managing the construction progress of the construction master control plan based on the current construction master control plan and the ternary closed-loop mapping relationship.

[0030] Step S106 specifically includes the following steps: Step S1061: Based on the construction project requirements and the ternary closed-loop mapping relationship, the current construction master control plan is divided and compiled to generate corresponding monthly construction plans; Specifically, step S1061 determines the corresponding BIM model components and the physical spaces to which the BIM model components belong through a ternary closed-loop mapping relationship based on the WBS construction tasks involved in the current construction master control plan; Based on the construction project requirements and physical space, the WBS construction tasks are divided and compiled, the corresponding monthly construction plan is generated, and the start time, end time and dependency relationships of each monthly construction plan are set.

[0031] It should be noted that step S1061 is one of the steps in dynamically coordinating plans using a ternary closed-loop mapping relationship. Specifically, the construction master control plan (level 1 plan) is developed by the project management team based on the overall project objectives, key milestones, and overall resource constraints. The construction master control plan clearly defines the project's macro timeframe, key milestones, and overall resource budget. Figure 4 : is a flowchart of collaborative feedback of multi-level plan preparation according to an embodiment of the present application, such as Figure 4 As shown in the figure, the monthly construction plan (secondary plan) is based on the construction project requirements (such as project logic, resource constraints and engineering experience), combined with the ternary closed-loop mapping relationship (such as Figure 4 As shown in the figure, the ternary closed-loop mapping relationship between WBS, BIM, and physical space in the BIM model space topology mapping is used to automatically introduce physical space to construct the spatial fence of BIM components. In order to subdivide the WBS construction tasks and corresponding BIM components of the first-level plan in dynamic plan collaboration and generate the corresponding second-level plan), the overall construction control plan is divided and compiled to refine the spatial tasks. The determined monthly construction plan clearly defines the time window (planned start and end dates) and scope of each spatial task (such as "air conditioning installation in room 101").

[0032] It should be further explained that when the general construction control plan triggers the execution of the division and compilation instructions, the system automatically starts the constraint verification process, calls the BIM model components bound to the task from the mapping rule library, and filters out the physical space to which the above components belong based on the ternary closed-loop mapping relationship. Operations on the bound components are only allowed within the filtered physical space. Through the above process, a strong constraint chain of "WBS task → target component → limited space" is formed to ensure the spatial uniqueness and component accuracy of task execution.

[0033] Step S1062: Based on the construction team information and the ternary closed-loop mapping relationship, the monthly construction plan is divided and compiled to generate corresponding construction team plans; Specifically, step S1062 determines the physical space that the construction team is responsible for based on the construction team information in the monthly construction plan, and determines the BIM model components and WBS construction tasks contained in the physical space through a ternary closed-loop mapping relationship; Based on the construction team information and BIM model components, the WBS construction tasks are divided and compiled, the corresponding construction team plan is generated, and the planning-related information of the construction team plan is calculated.

[0034] It should be noted that step S1062 is also one of the steps for performing dynamic planning collaboration using the ternary closed-loop mapping relationship. Figure 4 As shown, the ternary closed-loop mapping relationship among WBS, BIM, and physical space in the BIM model space topology mapping is used to generate a space task package organized by physical space, which contains the corresponding BIM model components and WBS construction tasks, as well as a unique associated QR code; the physical space that the construction team is responsible for is determined based on the construction team information (for example, the construction team scans the QR code of the physical space through a mobile device, the system pushes the corresponding task package, and the scan activates the action to confirm the receipt of the task package); and then combined with the actual situation of the construction site (such as labor, materials, environment, etc.), as shown Figure 4As shown, in dynamic planning collaboration, the third-level plan is associated with the corresponding second-level plan to generate the corresponding construction team plan (third-level plan). Its time window is limited to the time window of the corresponding second-level plan, and the planning-related information of the construction team plan is calculated. The specific calculation rules are as follows: ① Input and obtain data: extract the remaining planned duration and remaining project volume of the WBS construction task from the monthly construction plan; then obtain the current cumulative completion rate and actual consumed working hours; retrieve the preset standard labor efficiency value (unit: project volume / person-day) from the quota database; ② Generate the default team number: calculate the minimum positive integer that satisfies "standard labor efficiency value * number of people * remaining planned duration ≥ remaining project volume", and round up if it is not an integer; ③ Generate the default target completion rate: calculate the sum of the current cumulative completion rate and the incremental value, and the incremental value is "standard labor efficiency value * default team number * number of days in the planning cycle ÷ remaining project volume" (number of days in the planning cycle: 1 day for daily planning and 7 days for weekly planning). If the result exceeds 100%, only 100% is taken; It is further necessary to explain that if Figure 4 As shown, the construction team plan also includes a default indicator calculation and decision-making support mechanism. Specifically, the first is the manual review and adjustment process: the system pre-populates the plan form with the default team size and target completion rate. The team then adjusts the parameters based on a four-dimensional set of on-site factors, including available labor allocation, material arrival schedule, construction environment interference, and process connection technical conditions. Second, real-time support for auxiliary decision-making: ① Construction period pressure warning: Based on the user-adjusted team size and target completion rate, the construction period is predicted by reverse deduction (remaining construction volume ÷ standard labor efficiency value ÷ adjusted team size). When the predicted construction period is greater than the remaining planned construction period, an overdue days alarm is automatically generated (overdue days = predicted construction period - remaining planned construction period); ② Component construction volume verification: In response to the user's operation of selecting components in the BIM model: the percentage of the total weight of the selected component set to the total weight of the current spatial task (the component weight is determined by the construction volume or complexity) is automatically calculated, and the theoretical working time requirement of the selected component is output (this percentage * remaining construction volume ÷ standard labor efficiency value); ③ Historical work efficiency benchmarking: Display the historical work efficiency reference data set (minimum, average, maximum), calculate the planned work efficiency value and compare it with the historical reference value, and output the quantitative result (for example, "the current value reaches 92% of the historical average").

[0035] In addition, if Figure 4As shown, the construction team plan also features a backend spatial simulation mechanism. After the team submits its plan, the system automatically triggers a backend spatial feasibility simulation to check for physical or resource conflicts between WBS construction tasks. If approved, an execution instruction is issued; if not, a conflict alert is issued, triggering a conflict detection and two-way adjustment mechanism. The construction team plan also features a conflict detection and two-way adjustment mechanism: it continuously monitors and immediately responds to submissions or updates to construction team plans (third-level plans). Conflicts (such as advances, delays, and scope changes) between the constraints (time windows) set by the third-level plan (planned time) and its associated second-level plan (monthly plan) are automatically detected. Approved (or authorized) and reasonable changes to team plan details allow for upward adjustments to the corresponding second-level plan (for backward compatibility). Alternatively, if there is a significant discrepancy between the team plan and the overall objectives of the second-level plan, batch adjustments to the second-level plan are made, and the parent (e.g., the first-level plan) is promptly notified of potential impacts.

[0036] Step S1063: Manage the construction progress of the monthly construction plan and the overall construction control plan based on the construction progress of the construction team plan.

[0037] Specifically, step S1063 calculates the progress deviation of the construction team plan based on the actual construction progress and expected completion time of each construction team plan, and based on the progress deviation, controls the construction progress of the corresponding monthly construction plan and the overall construction control plan step by step.

[0038] It should be noted that regarding the dynamic collection and processing of construction team progress plans, once a team activates a task package, the system locks associated components based on a ternary mapping rule library. The target component is highlighted on the mobile progress reporting interface. The team then clicks or boxes to select completed components. The system then calculates the task completion rate based on the component's weighted quantity and updates it in real time to the BIM model and plan libraries. Furthermore, the system continuously monitors the overall deviation between the secondary plan and actual construction progress. When the deviation exceeds a preset threshold (e.g., time deviation > 3 days, quantity progress deviation > 5%, or a threat to the critical path), the secondary plan is adjusted (by rescheduling nodes and reallocating resources), and a risk alert is issued to the primary plan. The system also continuously monitors WBS construction tasks currently underway or about to be constructed within the same physical space. Based on ternary mapping rules, task progress, dependencies, and BIM model coordinate data, it detects physical space conflicts (coordinate collisions) and process logic conflicts (dependencies, progress, and time overlaps). It then provides warnings, coordination suggestions, or automatically triggers fine-tuning instructions to ensure smooth construction.

[0039] Through the above steps in the embodiment of the present application, multi-level dynamic closed-loop management of the construction master control plan is achieved by utilizing the ternary closed-loop mapping relationship, which can effectively deal with the disconnection and conflict between the actual construction progress and the expected progress, effectively coordinate possible process confusion and operation conflicts between multiple construction teams, and solve the problem of how to improve the construction progress management efficiency based on the building information model.

[0040] The preferred embodiment of the present application provides a construction progress management method based on BIM space ternary mapping, and the method of the preferred embodiment includes the following steps: Step 1: Model processing: Obtain the basement BIM model and extract the spatial coordinates and boundaries of each room. Associate each sub-project of the mechanical and electrical installation (such as piping and duct installation) with BIM components and map them to the corresponding room spaces. For example, associate all fire protection piping components in room R001 with the WBS item "Fire Protection Pipe Installation."

[0041] Step 2: Generate a secondary plan: The system automatically lists the required mechanical and electrical installation tasks for each room (for example, room R001 requires fire protection piping and cable tray installation). Based on this list of tasks, planning engineers create a secondary (monthly) plan in the project management software, setting the start and end times and dependencies for each task.

[0042] Step 3: Team task collection and three-level plan generation: The construction team uses the mobile app to enter the basement room R001. They click the spatial positioning button in the app, and the app automatically obtains the current location. The system displays the tasks to be performed in the room (fire protection pipe installation, cable tray installation). The preferred embodiment uses positioning means to determine the corresponding physical space, while step S1062 of the above embodiment uses scanning a QR code to determine. There are many ways to determine the physical space, which will not be detailed here. The team leader selects the "Fire Protection Pipe Installation" task. Based on the pipe length (project quantity) associated with the task and the work efficiency data for "Pipeline Installation" in the quota library (for example, each person can install 20 meters per day), the system automatically calculates the required working days (for example, 100 meters requires 5 man-days) and generates a three-level plan (weekly plan / team plan).

[0043] Step 4: Progress verification: Teams report their progress daily in the app (for example, "20 meters completed today"). The system automatically calculates progress deviations (planned completion minus actual completion) and uses the BIM 3D collision engine to verify spatial topology. It checks to see if other teams are performing conflicting tasks in the same space (for example, ceiling installation and plumbing work at the same height) and checks process logic (for example, piping installation should be completed before wall plastering).

[0044] Step 5: Plan revision: When the deviation exceeds a threshold (e.g., a 10% delay in progress) or a spatial conflict is detected, the system triggers a correction mechanism: it recalculates the installation duration for the remaining piping in that room (taking into account the current progress and remaining work load) and automatically adjusts the start time of subsequent related tasks in the secondary plan. Simultaneously, the system pushes a conflict alert to the relevant teams.
