[0022] To address the aforementioned technical problems, this disclosure provides an information management system for the project construction process. Figure 1 The diagram illustrates a schematic representation of a project construction process information management system. This system can be applied to the unified management of any engineering project and can be deployed on terminals such as mobile phones or computers. It can be accessed through a webpage or a standalone application. (Reference) Figure 1 As shown, the project's construction process information management system mainly includes the following modules: The project information management module 110 is used to establish project overview information, determine the project participants and the personnel management permissions of each participant, and realize project coordination management among the participants based on the project overview, participants and personnel management permissions, decompose the contract content into the project construction process, and perform process management on the execution of the contract to realize contract management. The project planning information model processing module 120 is used to determine the component unit elements of the project based on the project data, and to construct the project planning information model based on the component unit elements and logical relationships. The project planning information model is used to optimize the schedule and cost in the project construction organization plan, and to perform virtual simulation of the project construction process to determine key data of the construction process to guide the project construction process. The construction process management module 130 is used to manage one or more of the following aspects of the project construction process: progress management, quality management, cost management, and site and safety management. It determines the actual construction process data based on the key construction process data provided by the project planning information model, determines the deviation status of the project evaluation indicators based on the actual construction process data, and performs dynamic management of the project construction process and risk warning based on the deviation status.

[0023] The technical solution provided in this disclosure realizes contract management and project work coordination management among project participants through the project information management module; the project planning information model processing module can perform virtual simulation of the project construction process; the construction process management module can perform progress management, quality management, cost management, and site and safety management of the project construction process; the construction process management module can be adjusted based on the deviation status feedback of the actual construction process data, thereby accurately guiding project construction, increasing the information dimension of management, realizing unified management of multi-dimensional information, realizing the comprehensiveness of the project construction process information management system, improving the efficiency of project operation, and enabling timely risk warning.

[0024] Next, the project construction process information management system in the embodiments of this disclosure will be described in detail with reference to the accompanying drawings.

[0025] The project information management module 110 is used to establish project overview information, determine the project participants and their personnel management permissions, and realize project coordination management among the participants based on the project overview, participants and their personnel management permissions. It also decomposes the contract content into the project construction process and manages the execution of the contract to achieve contract management.

[0026] In this embodiment of the disclosure, the project overview information is used to describe the basic information of the project, which may include, but is not limited to, the project name, construction location, construction scale, total construction period, quality objectives, investment amount, engineering type, and key milestone plan. The key milestone plan may include commencement, completion and acceptance, etc. In addition, the project overview may also include document information such as the project feasibility study report, project approval, and planning permit.

[0027] The project participants can be any entity involved in the project, such as multiple participating units. Participating units may include the main construction unit and one or more subcontractors. Information for each participating unit may include its full name, unified social credit code, qualification level, contact information, project liaison department, and core business scope. After determining the project participants, a relationship network can be constructed based on a relationship network building module. For example, based on the collaborative and contractual relationships among multiple participating units, associated participating units corresponding to each participating unit are determined. Associated participating units refer to entities that have a relationship with a participating unit. Using the project as a node, each participating unit is treated as a secondary node, and the next-level node is determined based on the associated participating units corresponding to each participating unit to construct the relationship network. Contractual relationships can be determined based on signed formal contracts, while collaborative relationships can be determined based on project management responsibilities or business cooperation needs. For contracts between participating units, the main rights and obligations of the contracts can be broken down to key nodes in the project construction process.

[0028] In the relationship network, information about the relationships between participating entities can be labeled. This relationship information is used to determine relationships based on contractual or collaborative relationships. The relationship network can also be linked to data such as contract content, management personnel information, and coordination records, integrating these elements into the network's nodes. When a click on a participating entity's node is detected, the corresponding contract, management personnel information, and historical collaboration records can be viewed. If new participating entities are added during project construction, the constructed relationship network can be updated in real time based on these new entities. The project information management module can also store and manage participating entities' contracts according to the contract management module; for example, contracts with similar relationships can be stored together. For instance, the relationships between participating entities can be solidified to generate a visual relationship network interface, allowing managers to view the execution status at any time. The visual relationship network interface supports user clicks. If a click is detected on any node in the visual relationship network interface, the contract content, collaborative matters, and management personnel list for that participating entity can be displayed.

[0029] The project information management module may also include a permission determination module. This module identifies multiple participants for each participating entity and determines the level of personnel management permissions for each participant. Personnel management permissions include access permissions and operational permissions. Each participating entity can have multiple participants. Based on this, different levels of permissions can be assigned to each participant within each participating entity according to their level or position. Participants with Level 1 permissions can view the project overview, information on each participating entity, all contracts, and full coordination records; approve contract changes, claims, and settlement applications; initiate major thematic coordination meetings; adjust permission settings, and modify the constructed project planning information model. Participants with Level 2 permissions can view relevant information from their own unit and collaborating units; initiate daily coordination communications and thematic coordination meetings; submit / review contract payment and change applications; and update progress and quality records within their scope of responsibility. Participants with Level 3 permissions can view basic information related to their own work; submit progress completion status and material request applications; upload construction records, material acceptance forms, and other relevant documents; and receive and provide feedback on coordination instructions. Participants with level four access permissions can only view specified project information and have no operational permissions. Specified project information may include, for example, viewing contracts, settlement documents, and quality and safety records.

[0030] In some embodiments, the project information management module further includes a priority determination module, used to determine the instruction issuer and instruction implementer in the construction process from the corresponding construction processes of the participating entities. For example, from the relationship network of project participants, all associated participating entities related to the tasks to be performed in the project are screened, the rights and responsibilities of each associated participating entity in the tasks to be performed are clarified, and the instruction issuer and instruction implementer are determined based on these rights and responsibilities. When there are multiple instruction issuers for a task to be performed, the participating entity with the highest level or the professional participating entity is selected as the instruction issuer.

[0031] In this embodiment of the disclosure, based on the relationship network, mutual supervision and inspection among multiple participating entities can be realized, thereby achieving project coordination and management among the participating entities.

[0032] The project information management module may also include a contract management module for creating, storing, and managing contracts for all participating parties. It manages contract execution based on key contract events and milestones, enabling online review and signing. Specifically, key contract events can be linked to nodes in a relationship network, binding key events to nodes. Upon execution of any node, the bound key contract events are displayed. By establishing connections between the relationship network and nodes, contract content is broken down into project construction processes, allowing for process management of contract execution and thus contract management. Furthermore, it manages the contract performance process and provides an online contract signing platform. The project information management module also handles project-related approval procedures, online meetings, and notifications, achieving unified management of project information.

[0033] The project planning information model processing module 120 is used to determine the component unit elements of the project based on project data, and to construct the project planning information model based on the component unit elements and logical relationships. The project planning information model is used to optimize the schedule and cost in the project construction organization plan, and to perform virtual simulation of the project construction process to determine key data of the construction process to guide the construction process.

[0034] In this embodiment, project data includes architectural construction drawings, structural construction drawings, electromechanical installation drawings, etc. A component unit refers to the basic building block of the project planning information model, specifically, it can be a component derived from the project entities in the project data according to classification standards. Each component unit possesses component unit elements, based on which the project planning information model can be constructed according to the component unit elements and logical relationships. The project planning information model is used for virtual simulation of the project construction process. The simulation results obtained from the virtual simulation may include, but are not limited to, schedule simulation results, cost simulation results, resource allocation simulation results, and risk warning simulation results.

[0035] Component unit elements include one or more of the following: component identification code, component dimensions and spatial location information, component time and logical relationship, component quantity information, material category, quantity and pricing information, and component accessory information. Other information may also be included, depending on actual needs. The component identification code uniquely identifies the component unit. The component time can be the component's construction time. Pricing information can include material unit prices, management fees, comprehensive prices, etc. Component accessory information can include electronic scans or file links to contract information, component certificates of conformity, test reports, drawings, quality acceptance records, and specification clauses.

[0036] Using BIM (Building Information Modeling) software, three-dimensional geometric models of each component unit are built, and the component units are assembled. Using the component identifier code in the component unit elements as an index, the component unit elements are logically linked to their corresponding component units to construct a project planning information model. This project planning information model can be a three-dimensional project planning information model. After the three-dimensional project planning information model is constructed, it can only be adjusted when an adjustment operation at the target level is received. The target level permission can be either level one or level two, depending on the actual needs; no specific limitation is made here. It should be noted that geometric verification and information verification can also be performed on the constructed three-dimensional project planning information model. Geometric verification ensures that there are no spatial conflicts between component units. Information verification ensures the integrity, logical rationality, and relevance of component unit elements, such as matching component dimensions with component quantity information and ensuring that the component construction sequence matches practice. The model that passes both geometric and information verification is used as the three-dimensional project planning information model.

[0037] In this embodiment of the disclosure, a three-dimensional project planning information model is constructed by using multiple elements as component unit elements, which can improve the accuracy and comprehensiveness of the three-dimensional project planning information model and increase the dimensionality of the model.

[0038] The constructed project planning information model is used to optimize the schedule and cost in the project construction organization plan, and to conduct virtual simulation of the project construction process to determine key data to guide the project construction process. The project planning information model can be a three-dimensional information model of project construction planning, specifically a three-dimensional BIM information model of project construction planning, used to plan and schedule the project construction process to obtain the target construction plan. The target construction plan refers to the optimal construction organization plan obtained by comprehensively optimizing the project construction planning three-dimensional information model while taking into account factors such as project schedule and cost.

[0039] For example, network diagrams and critical path theory can be used to optimize construction schedules, and Gantt charts can be used to display the dynamic allocation of resources during the construction process. Earned value management theory can be used to comprehensively control schedule and cost during the construction process, and data-driven schedule-cost-risk analysis can be achieved to optimize the schedule and cost in the project construction organization plan. It should be noted that the optimization objectives may differ for different projects. For example, cost may be the optimization objective, schedule may be the objective, or both cost and schedule may be the optimization objective. No specific limitations are made here.

[0040] Virtual simulation of the project construction process can include one or more of the following: schedule simulation, cost simulation, resource allocation simulation, and risk warning simulation. For the critical path, specialized virtual simulations can be conducted to simulate the operational processes, the coordination of personnel and machinery, and the simulation effects of safety protection measures. It can also analyze potential risks during construction, such as schedule delays, cost overruns, quality and safety risks, and resource shortages. For risks identified in the simulation analysis, different display states are used in the project construction planning 3D information model to highlight the risk location, risk level, and recommended risk handling methods. The risk location can be the component unit where the risk is located, and warning information is automatically pushed to relevant management personnel. The display state can include display color, transparency, or size, etc. Targeted countermeasures are developed based on the risk type. For non-critical paths, one or more of the following can be used: schedule simulation, cost simulation, resource allocation simulation, and risk warning simulation. In the risk warning simulation of non-critical paths, only potential risks are simulated.

[0041] Virtual simulations visually present the progress and cost changes of the construction process at different stages, and can be displayed intuitively in the form of icons.

[0042] When constructing a 3D information model for project construction planning, a 3D project information model can be established based on the project overview information and personnel management permissions, as well as the design and project construction organization plan, thereby forming a 3D information model for project construction planning based on component unit attributes. Specifically, project overview information, personnel management permissions, and project construction organization plan can be bound to component identification codes to configure the attributes of each component unit according to the project overview information, personnel management permissions, and project construction organization plan, thus forming a 3D information model for project construction planning. Based on the spatial and logical relationships of components, the 3D information model for project construction planning can dynamically optimize the project construction organization plan based on different permission subjects for engineering indicators such as schedule and cost. It can also display the main indicators of the optimization process, realizing a visual dynamic simulation of the project construction process, and dynamically displaying the project's usage indicators over time. These usage indicators may include one or more of labor, materials, machinery, and cost.

[0043] After establishing a three-dimensional information model for project construction planning, relevant clauses of current standards can be embedded into the model to standardize the construction process. Based on the content of the standards, process management such as construction quality inspection / spot checks can be carried out to form corresponding quality management construction data.

[0044] The 3D information model for project construction planning can also generate target construction organization plans based on key construction process data provided in the model, thereby guiding the project construction process and facilitating its actual execution. The target construction organization plan refers to the optimal construction plan theoretically constructed based on the key construction process data in the 3D information model, and may be optimized based on actual implementation. Specifically, it can compare and analyze construction progress control and project cost accounting based on pricing elements, and update in real time to obtain the target construction organization plan.

[0045] For example, based on the construction time elements and logical relationships of component units in the project construction planning 3D information model, a preliminary construction schedule is automatically generated, and the construction schedules and priorities of the critical path and non-critical paths are determined. Further adjustments to the preliminary construction schedule can be made based on the critical path or actual schedule conflicts to obtain the final construction schedule. Based on parameters such as the quantity of work, material quantity, and pricing information of component units in the project construction planning 3D information model, the project cost is automatically generated. Schedule and cost are collaboratively optimized, and the solution that meets both cost and schedule requirements is selected as the target construction organization solution. This target construction organization solution is the optimal construction solution determined based on the key construction process data in the project construction planning 3D information model.

[0046] The construction process management module 130 is used to manage one or more of the following aspects of the project construction process: progress management, quality management, cost management, and site and safety management. It determines the actual construction process data based on the key construction process data provided by the project planning information model, determines the deviation status of the project evaluation indicators based on the actual construction process data, and performs dynamic management of the project construction process and provides risk warnings based on the deviation status.

[0047] In this embodiment of the disclosure, after obtaining the three-dimensional information model of the project construction plan, the project construction process information dynamic management model can be iteratively determined from the three-dimensional information model of the project construction plan. The project construction process information dynamic management model refers to the management model used to manage the project construction process, guide the implementation of the project construction process, and obtain actual construction process data.

[0048] During project construction, the planned construction process data obtained from the model is compared with the actual construction process data in real time. Deviations in project evaluation indicators are tracked through component identification codes. These indicators can be all or part of the data from the actual construction process, such as cost, schedule, and quality. They can also include quality or other indicators suitable for project evaluation. If deviations occur (such as delays in component construction or material overruns), the causes are analyzed based on simulation results. Authorized personnel then adjust the model and update the target construction organization plan to ensure the project construction proceeds according to the adjusted model's output construction organization plan.

[0049] For example, in terms of cost management and schedule management, construction can be carried out according to the key data of the construction process in the 3D information model of the project construction plan to obtain the actual construction process data. Since the 3D information model of the project construction plan may only contain construction process data for some construction units, for construction units whose construction process data is included in the 3D information model of the project construction plan, construction is guided by the key data of the construction process in the model to obtain the actual construction process data. For example, project schedule can be used as an important parameter, specifically using the time parameter in the model as key data to analyze its status. Cost management of the project construction process can be used as another parameter. Specifically, phased costs are reasonably decomposed into sub-projects and assigned to specific sub-projects. The cost of each sub-project is compared with the cost in the project planning information model to analyze cost deviations and determine the risk status. Key characteristics affecting costs may include engineering attribute characteristics, environmental condition characteristics, or process requirement characteristics, etc. For example, engineering attribute characteristics may include structural type, component size, construction location, and quantity of work. Process requirement characteristics may include material type, construction accuracy requirements, and schedule milestone requirements. For construction units that do not contain construction process data in the three-dimensional information model of project construction planning, key construction process data can be determined based on the historical data of the construction unit.

[0050] For construction process quality and on-site safety, the control parameters are mainly process data collected through the specifications and clauses. The data includes, but is not limited to, on-site photos and reliable third-party data, as well as the prescribed information on the construction process records.

[0051] After obtaining key construction process data, the 3D information model of the project construction planning, with parameters representing this key data, is defined as the dynamic management model for project construction process information. The project construction process can be executed according to this key data, and process documents such as construction-specific plans and safety plans can be prepared with the assistance of artificial intelligence tools, thereby obtaining actual construction process data. Specifically, the key construction process data can be fitted using artificial intelligence tools via an interface to obtain construction-specific plans and safety plans, thus obtaining actual construction process data. After obtaining the actual construction process data, the PDCA process in quality management can be executed, feeding the actual construction process data back to the model. The actual construction process data is compared with the planned construction process data in the model. Based on this, the deviation status of engineering evaluation indicators such as progress, cost, quality, and safety in the actual construction process data can be displayed. The key construction process data in the dynamic management model is updated according to the deviation status to ensure consistency with the actual construction status, and an optimized target construction organization plan is generated, realizing progress management, cost management, site and safety management, and quality management. The deviation status of different indicators can be represented using different display formats, such as different colors, for easy differentiation and viewing. Furthermore, it can provide handling methods for deviations. For deviations, information can be pushed to relevant personnel so they can promptly understand the situation and handle it according to their permissions. The optimized target construction organization plan guides construction process management, assigning elements such as planned time, contingency time, engineering consumption, and cost to component units. Engineering consumption includes the types and quantities of labor, materials, and machinery required for component unit construction. Based on the optimized target construction organization plan, construction can continue to obtain actual construction process data, and then key construction process data such as the construction period can be adjusted based on this data. (Reference) Figure 3 As shown, the dynamic management model for project construction process information can be adjusted according to the deviation status.

[0052] For example, if the schedule deviation in the deviation status does not meet the deviation requirements, the planned time of the delayed components can be adjusted to generate a new schedule, ensuring that the total project duration remains unchanged. If the cost deviation in the deviation status does not meet the deviation requirements, the actual cost data is entered into the component attributes, the cost data is updated, and cost forecasting and allocation are re-performed based on the updated cost data. The specific deviation requirements can be determined according to the actual project needs. In addition, the plans for personnel, machinery, and materials can be adjusted based on the resource usage in the actual construction process data, such as increasing the number of construction personnel for delayed processes, changing materials, etc. To achieve accuracy, the key data of the actual construction process can be updated multiple times, and the subsequent construction process can be guided by the dynamic management model of project construction process information. The process of acquiring actual construction process data, determining deviation status, and updating model parameters is executed cyclically until the project is completed, so that the project construction process reaches the optimal state of cost and duration. By adjusting the model parameters of the dynamic management model of project construction process information, the accuracy of the simulation is improved. During the adjustment, non-critical paths may also be adjusted to critical paths, and the model can be further adjusted on this basis. The process of building and adjusting the model can be performed on a computer to improve processing efficiency.

[0053] Based on the project planning information model, construction specifications for construction units are embedded. Actual progress, cost, and quality data from the construction site are collected and compared with the planned construction process data in the project construction planning 3D information model. Deviations are identified by comparing and analyzing the time and cost indicators included in the 3D information model. Model parameters are optimized in real time based on these deviations, and subsequent work is adjusted and optimized as needed, such as adjusting work schedules and optimizing resource allocation. After these iterative updates, the project construction planning 3D information model is updated into a project construction process information management model, realizing the transformation from planning simulation to dynamic control of the entire construction process.

[0054] The project construction process information management model in this embodiment establishes a three-dimensional information model based on project design data, and assigns basic attribute data, time elements, and logical relationships of construction process to the model component units in conjunction with the project construction organization plan. It can use network planning technology to optimize the project construction organization plan, output and display a visual Gantt chart, and show the dynamic change trend of the construction process based on the model.

[0055] A construction process management model can be established based on the 3D information model of the project construction plan. This model can then be used to implement one or more of the following: schedule management, quality management, cost management, and site and safety management. The construction process management model is essentially an information management model for the project construction process. Schedule management, quality management, cost management, and site and safety management can be the management of the schedule, quality, cost, and site and safety conditions according to the model plan. For example, schedule management can be a schedule plan, including start time, finish time, and construction sequence logic. Quality management can be based on collected site photos and measurement data, linking quality specification clauses to quality indicators determined by component units through component identification codes. Safety management is based on safety protection standards and risk levels. Cost management is based on the cost parameters of each component unit and construction unit. Specifically, based on the construction schedule plan generated by the project construction planning model, the core schedule parameters for each task or component unit are determined: planned start time, planned finish time, duration, prerequisite tasks, responsible person, and required resources, thereby achieving schedule management. Quality parameters, construction process standards, and acceptance specifications of component units generated by the project construction planning model can be embedded into the project construction process information management model to achieve quality management. High-risk areas at the construction site, generated based on deviations between the dynamic management model of project construction process information and the embedded project construction planning model, are associated with corresponding safety protection standards to achieve safety management. Based on the component quantities in the project construction planning model, the cost of each sub-item is automatically calculated, generating corresponding cost budget lists. Costs are broken down according to the construction schedule, forming cost control targets for multiple periods, which are then embedded into the dynamic management model of project construction process information to achieve cost management.

[0056] Specifically, the dynamic management model for project construction process information may include the following modules: a construction process progress management module, used to analyze the deviation between actual construction process data and planned construction process data determined by the project construction planning 3D information model, confirm or adjust the construction time of subsequent sub-projects, and optimize and execute subsequent work according to corresponding permission instructions. For example, the construction time of sub-projects can be brought forward or postponed. Personnel from each participating entity can issue instructions according to their own personnel management permissions or perform subsequent work according to received instructions.

[0057] The construction process cost management module is used to decompose and categorize construction costs, perform cost adjustments and management, and analyze and predict cost control risks. Specifically, it can break down construction costs into each sub-project, compare the cost of each sub-project with the planned cost output by the model, adjust the costs of subsequent sub-projects based on cost deviations, and predict cost control risks.

[0058] The construction site and safety management module is used to manage the allocation of construction personnel, materials, and machinery entry for subsequent construction content in the project's 3D construction planning model. It leverages big data to assist in developing specialized plans based on construction characteristics, records the execution process of construction document signing and approval, and manages the fulfillment of construction contract content. Specifically, the construction site management module can manage the quantity of personnel, materials, and machinery entry time for subsequent construction content based on key data output from the model. It can also manage construction plans, technical briefings, quality inspections, and process construction data, including on-site process management based on recorded images and videos. Furthermore, the project construction process information management system can be integrated with a big data module, inputting construction characteristics to enable specialized plan predictions. Additionally, it can automatically record the execution process of construction document signing and approval based on uploaded images and manage the fulfillment of construction contract content. Safety management can identify high-risk areas on the construction site based on deviations between the dynamic management model of the project construction process information and the embedded project construction planning model, and associate them with corresponding safety protection standards to achieve safety management.

[0059] The construction process quality management system is used to embed different construction contents of sub-projects into relevant current quality management standard clauses. It matches actual construction data with the standard clauses to conduct construction quality assessments, thereby achieving quality management. Different construction contents can embed different current quality management standard clauses, and construction quality assessments are conducted based on comparisons between on-site data and the data specified in the clauses. Through dynamic management of the project construction process, corresponding permission instructions can be adjusted.

[0060] The dynamic information management model for project construction processes can also be used for on-site management during project management. Specifically, it can connect to the on-site management interface based on the information management model for project construction processes to achieve facial recognition, attendance and training management, and can also perform on-site management and safety monitoring. For example, the on-site management module includes a construction site personnel management module and a safety hazard identification module. The construction site personnel management module is used for real-name personnel management, which includes at least construction process attendance, wage payment, safety technical briefings, and training. For example, attendance can be recorded based on personnel sign-in records or facial recognition results, and wages can be paid accordingly. In addition, safety technical briefings and training information can be provided to personnel based on their specific circumstances and positions.

[0061] The safety hazard identification module can acquire on-site images of the construction site through the on-site management interface. Based on these images, it performs intelligent image analysis and uses the results to monitor vehicles and equipment at the construction site, identify and issue warnings for potential safety hazards. Specifically, it can acquire monitoring images of the construction site from a fixed-location monitoring system with AI recognition capabilities. Based on these images, it manages and monitors the construction process and automatically identifies safety hazards, including smoking in the construction area and entering the construction area without protective gear. Safety monitoring refers to managing vehicle access and monitoring the safety of critical equipment at the construction site, such as tower cranes, elevators, and tall scaffolding. When a safety hazard is identified, a warning can be issued. In addition, drones can be controlled to periodically inspect the construction site along a preset route, acquiring inspection images through methods such as area photography, video capture, or scene scanning. Element analysis of inspection images determines the hazard level of the construction site. Based on the hazard level, a corresponding early warning signal is issued, and an alert is sent to the responsible personnel to facilitate timely intervention and minimize losses. Furthermore, the early warning signal can pinpoint hazardous locations within the construction site and provide suggested solutions. For example, an application installed on a terminal can be used to send the early warning signal to the responsible personnel to improve timeliness.

[0062] The aforementioned construction process management module may also include a data display module. The project construction process information management model can automatically compile daily construction list data. This data can include the manpower, material types and quantities required for each day's construction, as well as the types and quantities of machinery. Furthermore, it can generate and dynamically display the daily list data and the daily construction plan for each participating entity, distributing them to the corresponding entities to assist them in executing construction preparations. Different construction entities may have different daily construction plans. The daily construction plan includes the tasks to be completed, execution priorities, and project targets.

[0063] In some embodiments, the actual construction process data collected at the construction site can also be transmitted to the dynamic management model of project construction process information for storage and analysis, so as to facilitate access or issue instructions based on the data analysis results.

[0064] The dynamic management model for project construction process information can also standardize the construction process, implement the approval procedures for construction process supervision, and simultaneously organize construction data during the construction process to form a final archived electronic version of the construction data for storage.

[0065] Figure 3 The diagram illustrates the elements and processes involved in determining construction process management. (Reference) Figure 3 As shown, the project construction process is first planned based on the 3D information model of the project construction plan. Then, the project construction process is executed according to the dynamic management model of the project construction process information. Finally, the actual construction process data is checked, and the results are processed accordingly. Throughout the entire construction process management, factors such as schedule, cost, quality, and safety can be considered.

[0066] In this embodiment of the disclosure, the project planning information model processing module can perform virtual simulation of the project construction process. The construction process management module can adjust the construction process management module based on the deviation status feedback of the actual construction process data, thereby accurately guiding the project construction, improving the efficiency of construction process management, and enabling timely risk warning.
