[0001] The present invention belongs to the technical field of BIM, and in particular relates to a method and system for optimizing a construction plan based on BIM model changes. Background Art

[0002] In the traditional construction field, the planning and resource allocation of engineering projects are often based on experience or starting from scratch, which not only consumes a lot of manpower and time, but is also likely to lead to chaos and inefficiency in construction due to improper planning or miscalculation, and may even cause serious economic losses. Therefore, how to optimize the construction plan scientifically and efficiently is the goal that the construction industry has always pursued.

[0003] In recent years, with the rapid development of information technology, BIM technology has gradually been widely used in the construction industry. By creating a virtual model of a building, BIM technology can achieve full information integration, thereby improving construction efficiency and reducing construction costs. However, the existing construction plan optimization method based on BIM technology often ignores various changes that may occur during the construction process, such as design changes, construction errors, and construction delays. Once such changes occur, the original construction plan will be seriously disrupted. Summary of the invention

[0004] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a method and system for optimizing construction plans based on BIM model changes, which solves the construction problems caused by model changes through the interaction of model change acquisition and reminder, construction period adjustment and plan rescheduling.

[0008] This technical solution adopts the dual insurance measures of message queue and API interface to ensure that accurate and timely data can be obtained under any circumstances, and synchronize the latest data of the BIM model in real time after receiving the message of BIM model change.

[0022] Existing construction plan optimization based on BIM technology often ignores various changes that may occur during the construction process, resulting in serious disruption of the original construction plan due to changes, affecting the construction process. To this end, the present invention proposes a construction plan optimization method based on BIM technology specifically for model changes during the construction process. Through the interaction of model change acquisition and reminder, construction period adjustment and plan rescheduling, the construction problems caused by model changes are solved, ensuring the smooth progress of the construction project.

[0023] In some processes described in the specification and claims of the present invention and the above-mentioned drawings, multiple operations appearing in a specific order are included, but it should be clearly understood that these operations may not be performed in the order in which they appear in this document or may be performed in parallel. For example, step 1, step 2, etc. are only used to distinguish different operations, and the sequence number itself does not represent any execution order. In addition, these processes may include more or fewer operations, and these operations may be performed in sequence or in parallel.

[0024] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example 1

[0025] This embodiment provides a method for optimizing construction plans based on BIM model changes, which is used to optimize construction plans after model changes and ensure the smooth progress of construction projects.

[0026] like Figure 1 As shown, the method includes: Step 1: Obtain the change information and latest engineering quantity data of the BIM model.

[0027] In one implementation, a message queue (MQ) and API interface synchronization are combined to efficiently obtain changes and the latest data of the BIM model. This solution is highly reliable and flexible, and can meet various business needs, ensuring that the BIM model can be accurately obtained after changes, such as Figure 2 shown.

[0028] Specifically, by using message queues, you can monitor model changes in real time and ensure the real-time nature of data. This MQ-based real-time monitoring mechanism ensures that the latest model data is obtained in a timely manner so that you can respond when needed.

[0029] In order to avoid the failure of data acquisition due to MQ problems, the API interface is added as a backup solution. In this way, even if MQ fails, the change data of the BIM model can still be obtained through the API interface.

[0030] This double insurance measure ensures that accurate and timely data can be obtained in any situation. After receiving the message of BIM model change, the latest data of the BIM model is synchronized in real time.

[0031] Step 2: Providing a change reminder based on the change information.

[0032] For changes to the BIM model, users need to be reminded in a timely manner so that they can understand the details of the changes and take appropriate countermeasures.

[0033] Specifically, changes in the model will automatically trigger the calculation, and push reminders to users to remind them to pay attention to the changes.

[0034] To achieve this goal, we can do so in the following ways: a) Message reminder: Users can be reminded of changes in BIM models by sending in-site messages, SMS or email notifications. These messages may include the time, reason, scope of impact and model status after the change. In addition, personalized message reminder services can be customized according to the actual needs of users to better meet their needs.

[0035] b) Model content change reminder: In addition to message reminders, model content change reminders can also be used to let users know the details of BIM model changes. Specifically, some marks or prompts can be added to the model to inform users which parts have changed and the impact these changes may have on the project.

[0036] Through the above methods, users can be informed of BIM model changes in a timely manner and ensure that they understand the details of the changes. These reminder methods help improve user participation and project team collaboration efficiency, thereby better promoting the smooth progress of the project.

[0037] Step 3: Based on the change reminder and in combination with the latest engineering quantity data, calculate the labor, materials and construction period required for the changed project.

[0038] Based on the BIM model, detailed engineering quantity data of all processes can be obtained. These data cover key factors such as labor quota, material quota and construction period quota. By carefully analyzing these data and performing reasonable calculations and evaluations on them, accurate data on labor, materials and construction period required for the changed project can be obtained.

[0039] Drawing changes will lead to changes in the amount of work, that is, model version drawing differences. It is known that the amount of work = labor quota * number of people * construction period. By determining two of the values, the other can be accurately calculated. The labor quota is fixed, that is, how much work a person can complete in a day. The construction period is within a range for the project. The construction period can be adjusted by adjusting the construction plan, and the adjustment of the construction plan is mainly the adjustment of labor. For example, if it takes 15 days to complete a certain work standard, the time can be shortened by adding labor, but it must not be less than 7 days.

[0040] Specifically, labor quotas can help plan and manage human resources by understanding the actual number of workers required to complete a specific process. Material quotas provide the number of materials and equipment required for each process, making it easier to purchase and manage inventory in advance. Duration quotas provide the time required to complete each process, helping to develop a reasonable and efficient project plan and ensure that the project is completed on time.

[0041] Step 4: Optimize the calculated construction period.

[0042] Through step 3, we can obtain the preliminary expected duration of the project, and then fine-tune and optimize it by using various complex construction relationships. These relationships include the connection between each process, cross-operation, and parallel construction of multiple work lines. In addition, we need to fully consider various factors in the actual construction process, such as environmental conditions, resource allocation, personnel arrangements, etc., in order to make fine adjustments to the duration.

[0043] Step 5: Based on the optimized construction period, the construction plan is replanned in combination with the labor and materials required for the changed project to obtain an optimized construction plan.

[0044] After the adjustment of the construction period, the construction plan needs to be re-planned and arranged. This process involves the following steps, such as Figure 3 As shown: a) Comprehensively evaluate the current plan: Conduct a comprehensive evaluation of the existing construction plan to identify its strengths and weaknesses. The evaluation should be considered from multiple perspectives such as project progress, resource utilization and cost-effectiveness.

[0045] i. Collect data: Collect all relevant data about the current construction plan, including project progress, resource usage, cost expenditure, etc.

[0046] ii. Analyze progress: Compare actual progress with planned progress and identify causes of delays and potential risk points.

[0047] iii. Evaluate resources: Analyze the efficiency of resource utilization, including human, material, and financial resources, and identify areas of waste or shortage.

[0048] iv. Cost-Benefit Analysis: Compare the actual cost with the target cost to evaluate the economic benefits of the project.

[0049] b) Determine the rescheduling objectives: clarify the direction and objectives of the new construction plan. These objectives may include optimizing the project schedule, reducing costs, and improving resource utilization efficiency.

[0050] i. Clarify goals: Based on the evaluation results, clarify the goals that need to be achieved in the new plan, such as shortening construction period, reducing costs, improving quality, etc.

[0051] ii. Prioritize: Prioritize goals based on the overall project strategy and stakeholder needs.

[0052] c) Analyze influencing factors: Carefully analyze various factors that may affect the new construction plan, such as weather conditions, policy changes, resource supply, and actual on-site conditions.

[0053] i. External factors: Analyze the impact of external factors such as weather, policies, and market environment on the construction plan.

[0054] ii. Internal factors: Evaluate the project team’s capabilities, technical level, resource supply and other internal factors.

[0055] iii. Risk identification: Identify potential construction risks, such as technical difficulties, supply chain disruptions, etc. d) Develop a new plan: Based on the previous assessment and the determined rescheduling goals, develop a new construction plan. This plan should take into account various influencing factors and try to optimize various indicators to achieve the established goals.

[0056] i. Critical Path Method (CPM): Identify the critical tasks in the project and ensure that these tasks are completed on time to ensure the progress of the entire project.

[0057] ii. Resource balance: According to the availability and demand of resources, reasonably arrange the start and end time of each task to avoid resource conflict or waste.

[0058] iii. Risk Management: Consider risk mitigation measures in the plan, such as backup suppliers, emergency plans, etc.

[0059] iv. Comparison of multiple options: Develop multiple alternative options and select the best option by comparing the advantages and disadvantages of different options.

[0060] e) Review and revise the new plan: The new plan needs to be rigorously reviewed and revised to ensure its feasibility in practical operations. This may require discussions with members of the project team and necessary revisions and improvements to the plan.

[0061] i. Team discussion: Organize project team members to discuss the new plan and collect their opinions and suggestions.

[0062] ii. Simulation test: Use project management software to conduct simulation tests to evaluate the feasibility of the new plan in actual operations.

[0063] iii. Revision and improvement: Based on the results of team discussions and simulation tests, make necessary revisions and improvements to the new plan.

[0064] iv. Approval for release: After review and revision, the new plan is approved by the relevant responsible persons and released.

[0065] In general, the present invention presents an innovative solution based on the optimization of the construction plan of the general contractor management after the BIM model is changed.
