Technical Field

[0001] The present invention relates to the technical field of building construction management, and in particular to a building construction supervision method and system based on BIM. Background Art

[0002] The technical field of construction management involves planning, coordinating and controlling the process of construction projects from inception to completion, ensuring that the project is completed efficiently and safely within the established time frame and budget. This field emphasizes the criticality of project management plans, including cost management, time management, quality management, contract management and safety management. Construction management also involves the use of various tools and technologies, such as BIM (Building Information Modeling), to improve project transparency, efficiency and communication effectiveness, while minimizing resource waste and improving safety.

[0003] Among them, the construction supervision method focuses on supervising and inspecting the execution of construction projects to ensure that all work complies with project specifications, design standards and regulatory requirements. The main purpose of the method is to prevent errors and omissions in the construction process, ensure the quality of the project, and at the same time ensure construction safety and avoid accidents. The supervision method usually includes on-site inspections, progress tracking and resource allocation monitoring, as well as the use of technical means such as BIM tools for real-time data analysis and decision support, thereby optimizing the construction process and project management.

[0004] Existing technologies have obvious shortcomings in dynamic resource allocation and real-time progress feedback. Traditional methods rely on predetermined static plans during the construction process. Once deviations occur, it is difficult to make quick and accurate adjustments. This approach leads to low resource utilization, construction delays, and even quality problems. The lack of flexible task scheduling and resource reconfiguration capabilities leads to the postponement of key tasks due to insufficient resources, affecting the progress and safety of the entire project. Existing technologies lack effective real-time data analysis support, making it difficult for project managers to grasp the real-time status of the project and make optimal decisions.

[0061] See also Figure 1 The embodiment of the present invention provides a construction supervision method based on BIM. The processing flow of the method may include the following steps:

[0062] S1: Analyze construction task information based on the BIM model, extract task resource requirement values, space constraint values, and priority values, analyze and record the dependencies between tasks, sort the task priorities according to the space constraints, match the dependencies with the sorting results, and group them to generate a construction task priority grouping diagram;

[0063] S2: Based on the construction task priority grouping diagram, analyze the resource usage of the tasks in the group, compare the task priority ranking with the available resource usage, classify the resource allocation and space arrangement data of the grouped tasks, and generate a construction resource and task allocation table;

[0064] S3: Based on the construction resource and task allocation table, extract the task execution status and interruption signals in the real-time monitoring data, analyze the resource occupancy status of the interrupted tasks, adjust the resource demand values ​​of the unfinished tasks, match the resource allocation and dependency order of the priority tasks, combine the adjusted task status with the monitoring data, and generate a dynamic construction task reconstruction plan;

[0065] S4: Based on the dynamic construction task reconstruction plan, extract the resource occupancy values ​​of critical path and non-critical path tasks, analyze the construction period occupancy of critical path tasks, compare the resource utilization rate of non-critical path tasks with the current available resources, optimize the resource occupancy of critical path tasks, adjust the resource allocation ratio of non-critical path tasks, and generate critical path optimization and resource balancing results;

[0066] S5: Based on the results of critical path optimization and resource balancing, extract the status and resource utilization of task groups, analyze the differences in construction completion rates between tasks, classify and integrate the resource coordination status and construction schedule planning status of grouped tasks, and obtain the overall coordination planning results of the construction.

[0067] The construction task priority grouping diagram includes task grouping, priority sorting results, and spatial dependency identification. The construction resource and task allocation table includes resource type classification, grouped resource quantity, and spatial allocation details. The dynamic construction task reconstruction plan includes resource reconfiguration, priority adjustment, and dependency update. The critical path optimization and resource balancing results include critical path optimization measures, resource allocation ratio, and non-critical path resource efficiency. The overall construction coordination planning results include resource coordination plan, construction period planning status, and task completion rate analysis.

[0068] Specifically, if Figure 2 As shown in the figure, the steps of parsing construction task information based on the BIM model, extracting the resource requirement value, space constraint value, and priority value of the task, recording the dependency relationship between tasks, sorting the task priorities, matching the dependency relationship with the sorting results, and generating the construction task priority grouping diagram are as follows:

[0069] S101: Analyze construction task information based on the BIM model, extract resource requirement values, space constraint values, and priority values ​​of construction tasks, analyze logical relationships between tasks, record dependency relationships and constraint rules, and obtain task information dependency data;

[0070] The construction task information is parsed through the BIM model to obtain the resource demand value, space constraint value and priority value of each task, and the quantity of materials, equipment and labor resources required for each task is calculated and recorded in the task resource table. The space constraint value extracts the restriction conditions of each task in the spatial layout, such as space occupancy, traffic flow lines or overlapping of construction areas, by parsing the relationship between the space nodes and structural elements in the model. The priority value is extracted based on the time requirements, resource constraints and predecessor task requirements of the task to form a preliminary priority sorting of the tasks, analyze the dependencies between the tasks, determine which tasks are predecessor tasks and which are subsequent tasks, record the dependency data, extract the constraint rules of the construction tasks, such as time restrictions, resource sharing constraints, etc. The data is integrated to form task information dependency data, which provides a basis for subsequent task scheduling and sorting.

[0071] S102: extracting the spatial constraint value of the task based on the task information dependency data, adjusting and classifying the task priority value according to the constraint rules, and obtaining the task sorting data;

[0072] First, the spatial constraint value of each task is extracted from the task information dependency data. Combined with the resource requirements and time constraints of each task, a spatial constraint table is constructed. The spatial conflicts of each task are compared to determine which tasks cannot be executed in parallel due to spatial constraints. According to the constraint rules, those tasks with greater spatial constraints are adjusted first, and their priorities are lowered or their time is rearranged to ensure the optimal use of spatial resources. According to the adjusted priority and combined with the logical dependencies between tasks, the task priority values ​​are classified. By evaluating the tasks one by one and comprehensively considering the time, space and resource dependencies between tasks, the tasks are divided into multiple priority groups to form task sorting data, which not only reflects the order of task execution, but also reflects the interdependence of tasks and the adjusted priorities.

[0073] S103: Based on the task sorting data, group and classify the task priorities, match the dependency relationship and the grouping rules, assign the tasks to priority groups, and generate a construction task priority grouping diagram;

[0074] The tasks are divided into multiple groups according to the adjusted priorities. The grouping is based on factors such as the task's time window, resource availability, and space constraints. For example, tasks with higher priorities are assigned to the first group to ensure that the tasks can be started and completed as soon as possible, while tasks with lower priorities are placed in subsequent groups. According to the dependencies between tasks, the execution of tasks in each group is ensured to be non-conflicting. For example, tasks assigned to the first group cannot rely on the unfinished tasks in the second group. Based on the grouping rules, each task is assigned to the corresponding priority group, and a construction task priority grouping diagram is generated to clearly show the grouping of each task and its dependencies. This grouping diagram not only helps to control the overall construction process, but also provides an intuitive basis for resource scheduling and time scheduling in actual construction.

[0075] Specifically, if Figure 3 As shown in the figure, based on the construction task priority grouping diagram, the steps of comparing the task priority ranking and resource usage, classifying the resource allocation and space arrangement of the tasks, and generating the construction resource and task allocation table are as follows:

[0076] S201: Based on the construction task priority grouping diagram, extract the construction resource requirements and occupancy of the task, count the total amount of grouped resources, compare the current resources, record the resource constraints and task relationships, and obtain task resource occupancy data;

[0077] Extract the building resource requirements and occupancy of the task according to the formula:

[0078]

[0079] Calculate the resource usage of the task, where R task Represents the building resource usage of the task, R j represents the demand for the jth building resource, T j is the occupancy coefficient of the corresponding resource, and m is the number of resource types;

[0080] Detailed explanation of the formula and the process of formula calculation and derivation:

[0081] In the above formula, R j Indicates the number of resources required by each resource type in the task, T i It is a coefficient obtained based on the priority and allocation ratio of the task. The resource occupancy is calculated by multiplying the demand for each resource by the corresponding occupancy coefficient. The coefficient T jDepending on the criticality and priority of the task, for Task A, the resources need to be accurately measured in order to be reasonably allocated. If Task A requires three types of resources, namely personnel, machinery and materials, with R1 = 10, R2 = 5, and R3 = 8, respectively, and the occupancy coefficient of each type of resource is T1 = 1.2, T2 = 0.9, and T3 = 1.0, the resource occupancy is calculated by the following formula:

[0082] R task =10·1.2+5·0.9+8·1.0=12+4.5+8=24.5

[0083] The result shows that the resource demand of Task A is 24.5 units. The resource occupancy data can be used as the basis for subsequent resource allocation and scheduling to ensure that resources are not excessive or insufficient during the construction process. Based on this occupancy, it is also necessary to compare it with the available resources in the existing resource pool to further determine whether the resources are sufficient and whether the resource allocation needs to be adjusted. This calculation can provide necessary data support for subsequent resource arrangement and scheduling in the early stages of construction.

[0084] S202: Based on the task resource occupancy data, extract the building resource demand information, verify the resource allocation rules, gradually compare and adjust the resource demand and available quantity, record the resource allocation and remaining situation, and obtain the group resource allocation data;

[0085] Extract the building resource demand information required for each task from the task resource occupancy data to ensure that the resource demand items of each task are clear and matched with the actual available resource pool. This involves the accurate extraction of different resource requirements in the task, ensuring the accurate estimation of the resources required for each task, avoiding the impact of incorrect resource demand data on subsequent resource allocation, and verifying according to the existing resource allocation rules to ensure that the resources required for the task do not exceed the upper limit of the available resources in the resource pool. Use the verification rules to compare resource requirements and available quantities, and adjust the resource demand data one by one to avoid improper allocation or resource shortages. The comparison of resource requirements and available resources can effectively detect problems in resource allocation and make adjustments on this basis. By recording the specific situation of each resource allocation, it is ensured that the subsequent resource scheduling work can be based on real-time and accurate allocation data, and all remaining resources can also be reasonably recorded and adjusted, so as to more efficiently redistribute or schedule resources. Obtaining resource allocation data will provide a clear resource allocation plan for each task to ensure the smooth execution of tasks without resource bottlenecks.

[0086] S203: based on the grouped resource allocation data, extract the spatial parameters of resource allocation, analyze the spatial demand value, compare the spatial arrangement with the resource location, adjust the spatial distribution, and generate a construction resource and task allocation table;

[0087] According to the completed group resource allocation data, the first task is to extract the space demand parameters of each resource. The space occupancy of each resource type in construction is the basis for formulating the space allocation plan. Therefore, it is necessary to extract specific information about space occupancy from the task resource allocation to ensure that the space demand of each type of resource is accurately measured. For example, personnel need a certain amount of activity space, mechanical equipment needs sufficient operation area, and materials need to reserve storage area. The space demand will be parsed into specific space demand values ​​to facilitate subsequent space optimization. It is necessary to compare the space demand with the existing space arrangement to analyze whether the location allocation of existing resources can meet the space demand. If it is found that there is a conflict or mismatch between the space arrangement and the location of the resource, the space distribution needs to be adjusted to allocate appropriate space for each task, which involves the reconfiguration of space to ensure that resources can be arranged efficiently and safely at the construction site. The adjusted space distribution plan will generate a construction resource and task allocation table through accurate data records. The table provides detailed space resource arrangement information for actual construction operations to ensure that each task can proceed smoothly during the execution process, while avoiding resource congestion or waste.

[0088] Specifically, if Figure 4 As shown in the figure, based on the construction resource and task allocation table, the resource occupancy of the interrupted tasks is analyzed, the resource requirements of the unfinished tasks are adjusted, the resource allocation and priority dependency order are matched, and the steps of generating a dynamic construction task reconstruction plan in combination with the monitoring data are as follows:

[0089] S301: Based on the construction resource and task allocation table, extract the task execution status, analyze the task identifier and execution mark, match the task resource occupation parameters, check the resource type and quantity, record the mapping relationship between the task and the resource, and obtain the interrupted task resource occupation data;

[0090] Through task identification, the execution status of each task and its associated resources can be accurately identified to ensure real-time updating of resource occupancy. The types of resources required for each task can be compared to ensure that resource allocation is consistent with the task execution plan. The types and quantities of resources can be checked in detail to ensure the accuracy of the number of resources required for each task. The resource occupancy data will be continuously optimized through the verification and validation process to ensure full utilization and scheduling of resources during the execution of various tasks. The mapping relationship between tasks and resources is recorded so that the relevant resource occupancy can be quickly retrieved during the execution of subsequent tasks, and the resource occupancy data of interrupted tasks can be obtained. Through the mapping relationship between tasks and resources, the dynamic changes of each task's resources can be accurately traced to ensure that the task status information is in a controllable state throughout the process and provide a true and reliable basis for resource scheduling.

[0091] S302: based on the interrupted task resource occupancy data, extract the resource requirements of the unfinished tasks, compare the resource occupancy details with the available resources, update the resource allocation parameters, update the task resource allocation and execution order based on the priority, and obtain the task resource and dependency adjustment data;

[0092] First, it is necessary to confirm which tasks have been interrupted for some reason, find out the resource demand data of the unfinished tasks, and analyze the data in detail, compare the resource occupancy details of the tasks with the currently available resources, and check the remaining availability of each resource. Through comparative analysis, readjust the resource allocation parameters to ensure that each resource is reasonably and effectively scheduled to avoid waste or overuse of resources. In the process of updating resource allocation parameters, tasks with higher priority should be given priority to resource support, and the resource allocation ratio should be adjusted according to the criticality of the task. Combined with the task priority, the task resource allocation and execution order are gradually updated to ensure that high-priority tasks can be smoothly carried out as planned and to avoid task delays due to insufficient resources. Through real-time comparison and adjustment of resource occupancy and task requirements, task resource and dependency adjustment data are obtained so that each task can be accurately scheduled and executed in the subsequent execution process.

[0093] S303: Based on the task resources and dependency adjustment data, a dynamic priority resource optimization algorithm is adopted, combined with the task execution status, the task identification and status record are updated, the resource allocation and dependency order are remapped, the execution arrangement of the priority tasks is adjusted, and a dynamic construction task reconstruction plan is generated;

[0094] The formula of the dynamic priority resource optimization algorithm is as follows:

[0095]

[0096] Calculate the priority limit of the task;

[0097] Among them, P new Represents the priority limit of the task, W r Represents the resource optimization weight coefficient, T d represents the expected completion time of the task, T o Represents the current estimated completion time of the task, T r Represents the total duration of the available time window of the task resources, R a represents the complexity of task resource requirements, W t represents the time sensitivity weight coefficient, D i represents the initial dependency order of tasks, D f Represents the task dependency order;

[0098] Detailed explanation of the formula and the process of formula calculation and derivation

[0099] This formula is used to calculate the new dynamic priority value P of the task new, whose calculation takes into account task resource optimization, time scheduling sensitivity, and changes in task dependency order;

[0100] W r is the resource optimization weight coefficient, which reflects the impact of the optimization degree of task execution resources on the priority. This value is set according to the urgency and complexity of the task resources in the project. After analysis, W r =0.8, the setting value indicates that the weight of resource optimization is higher, which is suitable for scenarios where most tasks rely on strong resources. As the availability of task resources increases, W r will gradually decrease;

[0101] T d is the expected completion time of the task, which indicates the target time when the task should be completed. According to the output of the project scheduling management system, the expected completion time of the task is: T d = 48 hours, which is obtained from the plan through the project time management tool;

[0102] T o It is the current estimated completion time of the task, which indicates the estimated time of the task execution progress. The current estimated completion time of the task is calculated as: T o = 54 hours, which is dynamically updated by the task tracking system based on the task execution status;

[0103] T r It is the total duration of the available time window of the task resources, reflecting the total time that the resources can be used for the task. According to the calculation of the resource scheduling system, the available time of the task is: T r =72 hours, this value takes into account the impact of resource allocation tasks;

[0104] R a It is the complexity of the task resource requirements, reflecting the specific requirements of the task for resources. This value is determined according to the specific requirements of resource planning and task execution, and is calculated as: R a = 25 units of resources, determined based on actual resource consumption and task complexity data in project scheduling;

[0105] W t is the time sensitivity weight coefficient, which reflects the impact of the criticality of task time on priority. This value is set based on the sensitivity of the task schedule. t =0.9, indicating that task time has a greater impact on priority. As the time of task dependency approaches, the weight coefficient should increase;

[0106] D i It is the initial dependency order of the task, reflecting the dependency relationship before the task is executed. The initial dependency order is calculated as: i =3, based on the logical relationship between tasks in the project management system, the execution order of tasks in the project is set to 3;

[0107] D f is the task dependency order, which indicates the dependency order updated after the task is executed. The final dependency order is calculated as: f =2, the task dependency order has changed, and the new execution order is 2;

[0108] First calculate the resource optimization part:

[0109]

[0110] Then calculate the time-sensitive part:

[0111]

[0112] Finally calculate the priority threshold:

[0113] P new =0.8×0.07792×1.45=0.09047

[0114] The result shows that the new dynamic priority value of the task is P new =0.09047. This value indicates the new state of the task's execution priority after adjustment. According to the task priority sorting strategy, the task with a smaller value will be executed first. The value of 0.09047 indicates that the priority of the task is relatively high, and it has a strong impact on the adjustment of resource optimization and time scheduling.

[0115] Specifically, if Figure 5 As shown in the figure, based on the dynamic construction task reconstruction scheme, the resource occupancy values ​​of critical and non-critical path tasks are extracted, the duration occupancy of critical path tasks is analyzed, the resource occupancy of critical path tasks is optimized, and the resource allocation ratio of non-critical path tasks is adjusted. The specific steps to generate the critical path optimization and resource balancing results are as follows:

[0116] S401: Based on the dynamic construction task reconstruction plan, extract the resource occupancy values ​​of the critical and non-critical path tasks, analyze the resource usage status of the critical path tasks, count the duration of the construction period, record the resource distribution ratio, and obtain the path task resource and construction period data;

[0117] First, the dynamic construction tasks are allocated and adjusted through the task scheduling system, and the critical path tasks and non-critical path tasks are identified. For critical path tasks, the resource occupancy of each task is obtained through the system's resource management module, including the allocation of equipment, personnel and materials. The resource requirements of each task are determined according to the type, duration and stage allocation of the task, so as to obtain the resource occupancy value, analyze the resource usage status of the critical path tasks, and calculate the occupancy time of each task in combination with the actual construction period, and record it in the database. The resource distribution ratio is determined by the ratio of the resource requirements of each task to the total resources, so as to clearly understand the contribution of each task to the total resource requirements. For non-critical path tasks, the resource occupancy value is extracted in the same way, and by comparing it with the resource requirements of the critical path tasks, the resource allocation plan is further optimized to obtain the path task resource and construction period data. All data are recorded in the path task resource and construction period data table for subsequent analysis and adjustment.

[0118] S402: Based on the path task resources and duration data, compare the resource utilization of non-critical path tasks, analyze the duration requirements of critical path tasks, adjust resource usage, modify resource requirement parameters and task priorities, and obtain optimized path resource allocation data;

[0119] A detailed comparative analysis of the resource utilization of non-critical path tasks is conducted. The resource utilization is calculated by the ratio between the actual resource usage of each non-critical path task and the scheduled resource demand. The differences between tasks are compared, tasks with low resource utilization are identified, and marked as potential optimization objects. The duration requirements of critical path tasks are deeply analyzed to determine whether there is a risk of delay or room for optimization. By comparing the existing resource requirements of tasks with the duration requirements, the resource usage of critical path tasks is adjusted, and the resource requirement parameters are dynamically modified according to the analysis results. For example, if the duration requirement of a critical task is too long, the resource allocation ratio of the task is automatically increased to speed up the progress, otherwise the resource allocation amount is reduced. The task priority will be modified accordingly according to the resource requirements and duration adjustment, giving priority to ensuring the smooth completion of critical path tasks that have a greater impact on the duration, and obtaining the optimized path resource allocation data so that the construction team can adjust the construction plan according to the new resource plan.

[0120] S403: Based on the optimized path resource allocation data, calculate the resource allocation optimization coefficient of the critical path task, check the resource usage ratio of the critical path task, compare the resource and duration distribution of the non-critical path task, update the resource allocation details and duration arrangement, and generate the critical path optimization and resource balancing results;

[0121] The formula for calculating the resource allocation optimization coefficient of the critical path task is as follows:

[0122]

[0123] Among them, Z represents the resource allocation optimization coefficient of the critical path task, r i represents the resource usage of the i-th critical path task, d i represents the duration of the i-th critical path task, w1 represents the critical weight coefficient of resource usage, w2 represents the critical weight coefficient of duration, w3 represents the resource adjustment coefficient, w4 represents the duration adjustment coefficient, and n represents the total number of critical path tasks;

[0124] This formula is used to calculate the resource allocation optimization coefficient (Z) of the critical path task. This coefficient reflects the resource optimization effect under multi-task, limited resources and duration arrangement. The optimization coefficient Z determines the resource and duration distribution optimization result of the critical path in this step. By adjusting the weight coefficients w1, w2, w3 and w4, resource allocation and duration arrangement can be optimized to better balance the time and resource utilization of task execution;

[0125] r i : The resource usage of the i-th critical path task is determined by monitoring and collecting data on the amount of resources required for each task of the project. For example, it is quantitatively measured by monitoring the equipment, number of personnel, materials and other resources used in the project. The unit is resource unit;

[0126] d i : The duration of the i-th critical path task. Obtained through the project schedule and actual construction cycle data, the duration of each task is determined based on the actual project needs and expected progress, in days;

[0127] w1: The weight coefficient of resource usage, which reflects the criticality of resource allocation in optimization. It is set by the project manager's judgment on the urgency of resource demand. Setting w1 = 0.6 reflects the high criticality of resource demand.

[0128] w2: weight coefficient of the duration, which reflects the optimization requirements of each task duration. The setting value w2 = 0.4 means that duration optimization is relatively less important, and resource optimization is relatively more critical.

[0129] w3: Resource adjustment coefficient. This coefficient is used to adjust the flexibility of resource allocation between tasks. It is set by the adjustment range of actual resource allocation. Setting w3=3 means that higher flexibility allows wider adjustments.

[0130] w4: Construction period adjustment coefficient, which is used to control the flexibility of construction period adjustment. When w4=2 is set, it means that the adjustment of construction period is allowed to fluctuate within a certain range, but will not deviate too much from the original plan.

[0131] There are 3 critical path tasks, and the resource and duration data are as follows:

[0132] Task 1: resource usage r1 = 100 resource units, duration d1 = 5 days;

[0133] Task 2: resource usage r2 = 80 resource units, duration d2 = 6 days;

[0134] Task 3: Resource usage r3 = 120 resource units, duration d3 = 7 days;

[0135] Substituting into the formula:

[0136]

[0137]

[0138] The calculated Z≈0.7204 reflects the comprehensive effect of resource allocation and schedule optimization of the critical path under the existing resource and schedule arrangements. The value is close to 1, indicating that the resource and schedule allocation is relatively balanced, but there is still room for further optimization. Based on this value, project managers can adjust resource allocation and schedule arrangements to ensure more efficient use of resources for critical path tasks and avoid waste of resources for non-critical path tasks.

[0139] Specifically, if Figure 6 As shown in the figure, based on the results of critical path optimization and resource balancing, the status and resource utilization of task groups are extracted, the differences in the completion rates of tasks are analyzed, the resource coordination status and schedule planning status of tasks are integrated, and the steps to obtain the results of the overall coordination planning of construction are as follows:

[0140] S501: Based on the results of critical path optimization and resource balancing, extract the status parameters and resource utilization of task groups, count resource consumption and remaining resources, analyze the differences in duration completion rates, classify and record duration status, and obtain task group resource and duration status data;

[0141] Statistics on the resource consumption of each task grouping are obtained by extracting the resource usage of each task, including the computing resources, storage resources and execution time consumed by the task, and then calculating the remaining resources of the task. Combined with the current task progress, the status of each task is analyzed to determine whether the task is proceeding as planned. Resource consumption data can be obtained through real-time monitoring tools and compared with the maximum amount of resources required for the task to calculate the proportion of remaining resources. The completion rate of the construction period can be analyzed by comparing the difference between the planned construction period and the actual completion period. The completion status of each task is further refined. By recording the start and end time of each task, the changes in the construction period progress are statistically analyzed. For different task groups, tasks need to be classified into different construction period status categories according to resource status and construction period completion status. The basis for classification can be completion progress, resource consumption ratio, remaining resource status, etc., to obtain task group resource and construction period status data, to facilitate subsequent task adjustment and resource optimization.

[0142] S502: Based on the task grouping resources and duration status data, analyze the duration completion rate and resource status, integrate resource coordination parameters, adjust resource allocation for low-utilization tasks, update duration and resource matching results, and obtain grouped task coordination and planning data;

[0143] First, by comparing the completion rate of the construction period with the resource status, we analyze whether there is any waste or shortage of resources in the task, evaluate whether the resources are fully utilized, integrate the resource coordination parameters, and adjust the resource allocation of low-utilization tasks. If there is excess resources in low-utilization tasks, resources need to be reallocated to the tasks. The reallocation of resources can be done by comprehensively considering the resource dependencies between tasks, the priority of tasks, and the remaining resources of the current tasks. The resource allocation ratio is adjusted using the optimization method. The construction period adjustment also needs to be carried out simultaneously. By updating the construction period and resource matching results of the task, ensure that the progress of the task is not affected by the resource adjustment, and obtain the coordination and planning data of the grouped tasks as the basis for subsequent resource allocation and task scheduling.

[0144] S503: Based on the grouped task coordination and planning data, extract resource coordination status and construction period planning records, integrate global task resource allocation and construction period adjustment, adjust resource ratios and construction period planning parameters, and generate construction global coordination planning results;

[0145] First, extract the resource coordination status and construction schedule records, combine the resource allocation of each task with the construction schedule for global analysis, and integrate the resource allocation and construction schedule of all tasks to find resource conflicts or construction delays between tasks, and adjust the resource ratio and construction schedule parameters in time. The resource ratio adjustment is based on factors such as the priority, completion progress, and remaining resources of each task. At the same time, the adjustment of construction schedule parameters needs to consider the gap between the actual execution of the task and the target construction schedule. It is necessary to increase resources for certain tasks, or appropriately extend the construction schedule of some tasks to generate a global construction coordination planning result to ensure the matching of resources and construction schedules and achieve the optimization of the overall task progress.

[0147] The task information analysis module analyzes the construction task information based on the BIM model, calibrates and calibrates the task resource requirements, space constraints and priorities, maps the dependencies between tasks based on the cross-data, and obtains the task dependency analysis results;

[0148] The task priority grouping module uses the task dependency analysis results to sort out the task priorities, combines the spatial relationship between spatial data processing tasks, sorts the priorities of tasks and logically groups them to obtain the task priority grouping results;

[0149] The resource and task allocation module analyzes resource utilization efficiency based on the task priority grouping results, adjusts the resource allocation plan and matches the task priority and space requirements, and obtains resource allocation and space planning data;

[0150] The task status monitoring module uses real-time data monitoring technology to track task execution status and interruption according to resource allocation and space planning data, analyze resource utilization efficiency, and update task progress and resource status to obtain task execution status and resource occupancy data;

[0151] The task dynamic reconstruction module re-evaluates and adjusts resource allocation according to task execution status and resource occupancy data, optimizes the execution order of tasks and matches real-time monitoring feedback to generate dynamic task adjustment and allocation plans;
