Description

Technical Field

[0001] The present invention belongs to the field of BIM technology, and in particular relates to a method, device and medium for setting a buffer zone for a general contractor management construction plan. Background Art

[0002] In engineering projects, general contracting management plays a pivotal role, covering the entire process from design concept formation to construction completion. However, during the actual construction phase, various possible problems, such as design changes, material supply shortages, construction errors, etc., may lead to delays in the project progress. In order to ensure that the project can be completed on schedule, the general contracting management plan must include strategies for optimizing and adjusting possible construction delays or progress lags.

[0003] Although it is necessary to adjust the plan, too frequent adjustments often disrupt the original construction rhythm and have an adverse impact on on-site operations. Therefore, in order to avoid these potential delays from affecting the entire project, a certain buffer zone is usually set up during the construction phase. However, how to effectively set up and manage these buffer zones so that they can cope with emergencies while maintaining a stable construction schedule has always been a major challenge in general contracting management.

[0004] The traditional general contracting management method is usually to set up a buffer in each sub-project and then manage it separately. Although this method can subdivide the tasks, it also leads to a lot of duplication of work and makes it difficult to effectively allocate and manage resources at the project level. In addition, due to the lack of a unified management mechanism, the buffers between sub-projects may not be coordinated or even conflict, which further affects the stability of the project progress and the overall benefits of the project.

[0005] Therefore, there is an urgent need for a method for setting up a construction buffer zone in the general contractor management plan, which can effectively solve the above problems and improve the efficiency of engineering management and the overall benefits of the project. Summary of the invention

[0006] In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a method, device and medium for setting a construction plan buffer zone for general contractor management, and realizes accurate setting of the construction plan buffer zone through quantitative calculation of the buffer zone.

[0007] According to one aspect of the present invention, there is provided a method for setting a buffer zone for a general contractor management construction plan, comprising:

[0008] Obtain the mapping relationship between the process and the component according to the BIM model, and calculate the engineering quantity of each process according to the mapping relationship;

[0009] According to the engineering quantity of each process, combined with the construction period index quota database, the duration of each process is calculated, and the construction period of the entire project is calculated based on the duration of each process;

[0010] According to the engineering quantity of each process, combined with the labor index quota database, the man-days of each process are calculated, and the man-days of the entire project are calculated based on the man-days of each process;

[0011] According to the relationship between the construction period and working days and the buffer zone safety time, the buffer zone safety time of each process is calculated, and the buffer zone of the entire project is set according to the buffer zone safety time of each process.

[0012] The above technical solution uses BIM model data and related quota management database to quantify the buffer zone to ensure more accurate setting of the construction plan buffer zone. By setting the construction buffer zone, it reduces the trouble of frequent adjustment of the construction plan and improves the efficiency and accuracy of project management.

[0013] As a further technical solution, when setting the buffer of the entire project, it also includes:

[0014] Determine the start and end time of each process based on the precedence and precedence relationship of each process and the arrangement of parallel construction;

[0015] According to the start and end time of each process and the construction period requirements, the buffer zone safety time of each process is dynamically adjusted to form an executable construction plan.

[0016] After obtaining the buffer zone set according to the calculation results, the above technical scheme can dynamically adjust the buffer zone safety time in combination with the front and back relationship of the process, the parallel construction arrangement of multiple lines and the construction period requirements, so as to obtain a relatively accurate construction plan, which can not only meet the construction period requirements, but also improve the construction efficiency and quality.

[0017] As a further technical solution, after setting up the construction buffer zone, it also includes: monitoring the consumption rate of the buffer zone, and triggering an early warning when the consumption rate reaches a threshold range.

[0018] The above technical solution can monitor the project construction progress, timely discover possible problems in the project construction process, and conduct corresponding early warning analysis, which helps to ensure the project construction progress and quality, while improving construction efficiency and management level.

[0019] As a further technical solution, monitoring the consumption speed of the buffer further includes:

[0020] Monitor the remaining buffer and remaining man-days of the project, and trigger an early warning when the ratio of the remaining buffer to the remaining man-days of the project is less than the ratio of the total buffer to the total man-days of the project.

[0021] As a further technical solution, monitoring the consumption speed of the buffer further includes:

[0022] Monitor the buffer used by the current process, and trigger an alarm when the buffer time used by the current process is greater than the remaining buffer time minus the sum of the buffer times of all processes after the current process.

[0023] According to one aspect of the present invention, there is provided a device for setting a buffer zone for a general contractor management construction plan, comprising:

[0024] The engineering quantity calculation module is used to obtain the mapping relationship between the process and the component according to the BIM model, and calculate the engineering quantity of each process according to the mapping relationship;

[0025] The construction period calculation module is used to calculate the duration of each process based on the engineering quantity of each process and the construction period index quota library, and calculate the construction period of the entire project based on the duration of each process;

[0026] The man-day calculation module is used to calculate the man-days of each process based on the engineering quantity of each process and the labor index quota library, and calculate the man-days of the entire project based on the man-days of each process;

[0027] The buffer setting module is used to calculate the buffer safety time of each process according to the relationship between the construction period and working days and the buffer safety time, and set the buffer of the entire project according to the buffer safety time of each process.

[0028] As a further technical solution, the buffer setting module is also used to execute the following instructions:

[0029] Determine the start and end time of each process based on the precedence and precedence relationship of each process and the arrangement of parallel construction;

[0030] According to the start and end time of each process and the construction period requirements, the buffer zone safety time of each process is dynamically adjusted to form an executable construction plan.

[0031] As a further technical solution, the device also includes an early warning module for monitoring the consumption speed of the buffer zone and triggering an early warning when the consumption speed reaches a threshold range.

[0032] According to one aspect of the present invention, there is provided a computer storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of a method for setting a buffer zone for a general contractor to manage a construction plan.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The present invention utilizes BIM model data and related quota management database to perform quantitative calculations on the buffer zone to ensure a more accurate setting of the construction plan buffer zone.

[0039] In view of the inconvenience of setting up existing buffer zones, the present invention proposes a solution for optimizing the construction plan buffer zone in the general contractor management plan. The uniqueness of the solution lies in that the BIM model is combined to obtain the construction period and working day data of the general contractor management project, and a unique calculation method is used to set the buffer zone. Furthermore, through the setting of the construction buffer zone, the trouble of frequently adjusting the construction plan is reduced, and the efficiency and accuracy of project management are improved.

[0040] It should be noted that:

[0041] The construction period index quota library refers to the duration of each process under the standard engineering quantity, and the labor index quota library refers to the work efficiency index of the type of work required for each process under the standard engineering quantity. The data of these quota libraries are derived from industry standards, historical project data, research by professional institutions, and accumulation within the enterprise. The specific data may be confidential, but the existence and use of these quota libraries can be considered to be known to those skilled in the art.

[0042] The buffer zone refers to a period of safe time, which is set up to prevent construction delays from affecting the project. This period of safe time can cope with construction emergencies without affecting the stability of the construction progress.

[0043] 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.

[0044] 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.

[0045] Example 1

[0046] This embodiment provides a method for setting a general contractor management construction plan buffer zone, which is used to obtain the construction period and working day data of the general contractor management project in combination with the BIM model, and set the buffer zone based on the construction period and working day data.

[0047] like Figure 1 As shown, the method includes:

[0048] Step 1: Obtain the mapping relationship between processes and components according to the BIM model, and calculate the engineering quantity of each process according to the mapping relationship.

[0049] Specifically, the logical relationship between each process is extracted and parsed from the BIM model to form a process tree containing all relevant information, thereby clarifying the interdependence and sequence constraints between each process, and determining the mapping relationship between each process and the corresponding component.

[0050] Furthermore, the BIM model data and the engineering quantity of each component are obtained. According to the engineering quantity of each component, the engineering quantity of each process is calculated in combination with the mapping relationship between the process and the component.

[0051] For technical personnel in this field, after determining the construction project, the various processes required for the construction project are clear, and the component information corresponding to the process is retrieved from the component library of the BIM model. Since the engineering quantity of each component is determined, the engineering quantity of each process can be calculated.

[0052] Step 2, calculate the duration of each process according to the engineering quantity of each process and the construction period indicator quota library, and calculate the construction period of the entire project according to the duration of each process.

[0053] This step uses the construction period quota library (i.e. the duration of each process under the standard engineering quantity) to calculate the duration of each process, thereby determining the construction period of the entire project. This method not only takes into account the engineering quantity of each process, but also the duration of each process, so it can more accurately predict the construction period of the project.

[0054] The total construction period is calculated as follows:

[0055] Where G is the total construction period (assuming that all processes are serial), n is the number of processes, is the total amount of engineering work for a single process, It is the standard engineering quantity of the process in the construction period quota database. Duration of the process under standard engineering quantity, It is the artificial experience coefficient (the coefficient may be inconsistent between different processes).

[0056] Step 3, calculate the man-days of each process according to the engineering quantity of each process and the labor index quota database, and calculate the man-days of the entire project based on the man-days of each process.

[0057] Similar to the method of calculating construction period, the overall working days of the project can be further calculated by using the labor index quota library (that is, the work efficiency indicators of the types of work required for each process under the standard engineering quantity). Combined with the BIM model, the total amount of engineering work for different processes can be obtained, thereby calculating the total working days required for each type of work.

[0058] The calculation formula for each process day and the total project day is:

[0059] in The method of calculating working days for a single process and a single type of work is as follows: is the total amount of engineering work for a single process, It is the standard engineering quantity of the process in the labor quota index library. It is the work efficiency index for different types of work; It is the calculation method of the total man-days of the project, i represents different processes, j represents different types of work, and k represents the number of different types of work in the same process.

[0060] Step 4: Calculate the buffer safety time for each process based on the relationship between the construction period and working days and the buffer safety time, and set the buffer for the entire project based on the buffer safety time for each process.

[0061] like Figure 2 As shown, the buffer zone is the safety time of the process, and a safety time is set between two adjacent processes as a buffer zone.

[0062] Assuming that all the processes in the construction plan are serial (the next process starts after the previous process is completed), then according to Figure 2 The following formula can be obtained:

[0063] , i is the process index,

[0064] in They are the estimated duration, safety time (buffer zone) and actual duration of each process; G, S and T are the estimated duration, buffer zone and actual duration of the project respectively.

[0065] In safe time When setting, according to actual experience, the process safety time is roughly proportional to the process duration, which can be obtained Calculation method: ,in To calculate the coefficient of process safety time based on the construction period, the coefficients of different processes are different, so it is necessary to calculate the coefficients based on actual experience. to set it up.

[0066] In the actual construction process, in addition to paying attention to the impact of the construction period of the process, it is also necessary to fully consider the impact of the working day. According to actual experience, the setting of the process safety time is roughly proportional to the working day, and the relationship is: ,in To calculate the coefficient of process safety time based on working days, the coefficients of different processes are different, so it is necessary to calculate the coefficients based on actual experience. to set it up.

[0067] Based on the above effects of duration and working days on process buffer settings, and considering the relationship between process duration and working days, the safety time setting takes the minimum value, and the final calculation method for setting the process is obtained:

[0068]

[0069] The buffer zone setting of the entire construction plan can be derived from the above formula:

[0070]

[0071] As an implementation method, in the process of obtaining the construction plan, it is necessary to fully consider factors such as the front-end relationship of the process, the parallel construction of multiple lines, and the construction period requirements based on the buffer setting relationship derived above. Through a comprehensive analysis of these factors, the buffer time can be dynamically calculated to ensure that the construction period requirements are met and a relatively accurate construction plan is obtained.

[0072] Specifically, it is necessary to reasonably determine the start and end time of each process based on the dependencies between processes and the arrangement of parallel construction. At the same time, it is also necessary to consider the construction period requirements to ensure that the construction plan can be completed on time. When calculating the buffer time, it is necessary to make dynamic adjustments based on actual conditions to ensure the feasibility and accuracy of the construction plan.

[0073] Through dynamic adjustment of the buffer zone, a more accurate construction plan can be obtained to meet the requirements of the construction period, while also improving construction efficiency and quality.

[0074] It should be noted that: the dynamic meaning here is to manually adjust the buffer results calculated previously according to the relationship between the processes and the parallel situation of multiple lines. Just as an example, if there are two work lines, the duration of work line A is longer and the duration of work line B is shorter, if the deadlines for completion of lines AB are the same, then based on the buffer safety time obtained above, the buffer time of each process of work line B can be artificially increased and adjusted appropriately without having a significant impact on the entire construction.

[0075] This embodiment introduces the detailed method of setting up a construction buffer zone in the general contractor management plan. By combining the BIM model, the construction period and working day data of the general contractor management project can be obtained, and a unique calculation method can be used to set the buffer zone. At the same time, the buffer zone can be dynamically adjusted to obtain a more accurate construction plan.

[0076] Example 2

[0077] Based on the same inventive concept as in Example 1, Figure 3 As shown, in this embodiment, when a construction buffer zone has been set, the construction progress of the project is closely tracked, and the relationship between the actual process construction time, the remaining working days and the construction buffer time is analyzed.

[0078] Specifically, early warning analysis can be performed in the following ways:

[0079]

[0080] Among them, S and P are project buffer and total working days respectively. They are the remaining buffer and remaining working days of the project respectively; is the buffer used by process m, The remaining buffer is set for the unfinished processes after process m.

[0081] Specifically, in formula (1), when the ratio of the remaining buffer to the remaining man-days of the project is less than the ratio of the total buffer to the total man-days of the project, an early warning is required. This indicates that if the actual progress of the project lags behind the planned progress, then it is necessary to be vigilant and take measures to speed up the construction progress to ensure that the project can be completed on time.

[0082] In formula (2), when the buffer time used by process m is greater than the remaining buffer time minus the sum of the buffer times of all processes after process m, an early warning is required. This means that if the buffer time of a process exceeds the buffer time that can be used by the process, then it is necessary to be vigilant and take measures to adjust the construction plan to ensure that the project can proceed smoothly.

[0083] By using these two formulas, possible problems in the project construction process can be discovered in a timely manner and corresponding early warning analysis can be carried out, which will help ensure the construction progress and quality of the project while improving construction efficiency and management level.

[0084] In the above warning methods based on the two formulas, a warning can be triggered if any of the formulas is met.

[0085] This embodiment analyzes the buffer zone according to the actual construction progress, and if it is found that the consumption rate of the buffer zone exceeds the preset ratio, an early warning will be triggered immediately. This early warning mechanism helps to timely discover and prevent the buffer time from being consumed prematurely, thereby ensuring the smooth progress of the project. Example 3
