Technical Field
[0001] The present invention relates to the technical field of engineering project management, and particularly to a method, device, equipment and medium for EPC project schedule and measurement management. Background Art
[0002] An EPC project (Engineer Procure Construct Project) refers to a project in which the owner entrusts the entire design, procurement, and construction of the project to an engineering general contractor, and the general contractor is fully responsible for the project. The general contractor can subcontract part of the design, procurement, and construction tasks to subcontractors, and the subcontract contracts are signed between the general contractor and the subcontractors.
[0003] In traditional EPC project management, on the one hand, schedule and measurement management are independent of each other and have no connection, resulting in inconsistent measurement amounts and schedule output values for each period; on the other hand, during the process of schedule measurement management by the general contractor, there is also a lack of connection with the schedule measurement of each subcontracting unit of the project, resulting in a lack of restraint on subcontract measurement.
[0004] Existing engineering project management platforms or business models do not deeply study the management characteristics of EPC projects, ignoring the management requirements of the general contractor and subcontractors in terms of schedule - measurement. The following problems occur in actual business: data needs to be repeatedly sorted: after each subcontractor reports the schedule and measurement quantities, the general contractor needs to re - sort the output value and amount to the owner according to the general contract unit price corresponding to the quantities; data inconsistency: due to the lack of correlation between schedule and measurement data, when measuring each contract, it is inconsistent with the current schedule output value, and problems such as over - measurement and early measurement often occur, and the project cost is out of control; subcontract measurement is out of control: there is no connection between the subcontract schedule output value and the general contractor schedule output value, and there is no conversion between them, resulting in the subcontract measurement to the lower level not being restricted by the general contractor's measurement to the owner, and it often occurs that the settlement with the subcontractor exceeds the charge to the owner, bringing great business risks to the project.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The following will specifically describe the preferred embodiments of the present invention with reference to the drawings. The drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention.
[0019] The present invention discloses an EPC project progress and measurement management method, device, equipment, and medium, which can be used in a computer. The method, equipment, or computer-readable storage medium involved in the present invention can either be integrated with the above-mentioned equipment or be relatively independent.
[0020] A specific embodiment of the present invention discloses an EPC project progress and measurement management method, which can be executed by a computer, specifically by one or more processors of the computer. Figure 1 As shown, the EPC project progress and measurement management methods include: S101, constructing a construction deepening model of the EPC project, and determining a component tree of the BIM model based on the construction deepening model, wherein the EPC project includes a general contractor, subcontractors, and subcontract contracts; S102, based on the component tree, the general contractor, the subcontractor and the subcontract contract, obtain the general contractor work breakdown structure and the subcontract work breakdown structure, attach the leaf node of the subcontract work breakdown structure to the leaf node of the general contractor work breakdown structure, and obtain a detailed project schedule; S103. Fill in and measure the subcontract list items in the detailed project schedule to obtain the measured engineering quantity and measured amount of the EPC project.
[0021] Among them, the leaf node of the subcontract work breakdown structure is attached to the leaf node of the general contractor work breakdown structure, so that the general contractor can be associated with the progress measurement of each subcontracting unit of the project during the progress measurement management process, and the subcontract measurement can be constrained.
[0022] Compared with the prior art, the EPC project progress and measurement management method provided in this embodiment constructs a construction deepening model of the EPC project, determines the component tree of the BIM model based on the construction deepening model, wherein the EPC project includes a general contractor, a subcontractor and a subcontract contract; based on the component tree, the components of the general contractor and the subcontractor are compiled respectively to obtain the general contractor work breakdown structure and the subcontract work breakdown structure; with the BIM model as a link, the contract bill of quantities is deeply bound to the BIM model to generate a progress WBS, the leaf node of the subcontract work breakdown structure is attached to the leaf node of the general contractor work breakdown structure, and the project detailed schedule is obtained, so as to solve the problems of data duplication, data inconsistency and uncontrolled in the progress and measurement of the general contractor and the subcontractor, fill in and measure the subcontract list items of the project detailed schedule, obtain the measured engineering quantity and measured amount of the EPC project, realize the data connection from the progress output value to the measured amount, realize the progress output value conversion of the subcontractor and the general contractor, and realize efficient and accurate progress and measurement management.
[0023] In some embodiments, in step S101, a construction deepening model of the EPC project is constructed. Based on the construction deepening model, the component tree of the BIM model is determined. The construction deepening model of the EPC project is constructed through BIM technology, and the construction deepening model is analyzed to obtain the BIM (Building Information Modelling) model code. Based on the BIM model code, the component tree (MBS) of the BIM model is constructed. Among them, the component tree of the BIM model includes a first-level structure, a second-level structure, a third-level structure, and a fourth-level structure. The first-level structure is a unit project, the second-level structure is a sub-project, the third-level structure is a sub-item project, and the fourth-level structure is a component. Each MBS code corresponds to an entity component of the BIM model. The component tree M of the BIM model is a multi-level tree structure, and its multi-level tree structure is as follows: , the general structure of M is unit project - sub-project - sub-item project - component. Among them, the component is the leaf node of M, and its component is ; the EPC project includes a general contractor, subcontractors, and subcontract contracts. The general contractor corresponds to multiple subcontract contracts and multiple subcontractors, that is, one general contractor has multiple subcontract contracts and subcontractors, which is a one-to-many relationship.
[0024] In some embodiments, in step S102, based on the component tree, the general contractor, the subcontractors, and the subcontract contracts, the general contractor work breakdown structure and the subcontractor work breakdown structure are obtained. Taking the component tree of the BIM model as a reference, the general contractor prepares the WBS (Work Breakdown Structure) of the EPC project to obtain the general contractor work breakdown structure. Among them, the general contractor item list is used as the work package of the component in the general contractor work breakdown structure; by the general contractor preparing the overall WBS of the project, the general contractor will decompose the EPC project layer by layer according to the overall scope and objectives of the EPC project, combined with the component tree of the BIM model, to obtain the general contractor work breakdown structure. The general contractor work breakdown structure covers the whole process of the EPC project from design, procurement to construction and commissioning services, and clarifies the main tasks and sub-tasks at each stage, as well as the logical relationship between these tasks; when preparing, based on the component tree M of the BIM model, the components are decomposed downward, and the general contract project quantity item list is used as the work package under the component, , each leaf item list has a corresponding unit price, quantity, and total price; the general contractor work breakdown structure is a new tree structure , , the leaf nodes of the general contractor work breakdown structure , and there are multiple leaf nodes; With reference to the component tree of the BIM model, the WBS of the subcontractor is compiled based on multiple subcontract contracts and the general contractor work breakdown structure to obtain a subcontract work breakdown structure, wherein the subcontract list items are used as work packages under the subcontractor components. After the subcontractor obtains the subcontract contract, the WBS of the subcontractor is compiled according to the scope of work and responsibilities stipulated in the subcontract contract and the part of the general contractor work breakdown structure related to the subcontractor to obtain the subcontract work breakdown structure, that is, the WBS of each subcontractor is compiled separately to form multiple subcontract work breakdown structures , for Combine into a new tree structure , , is the subcontract number, The bill of quantities for each subcontract, It is a leaf list item. The leaf nodes of the subcontract work breakdown structure are: ; The leaf nodes of the subcontract work breakdown structure are attached to the leaf nodes of the general contractor work breakdown structure to obtain the detailed project schedule. In the preparation of the detailed project schedule, the general contractor work breakdown structure is used as the overall schedule WBS of the EPC project. On this basis, the following steps are taken to decompose the structure downwards: the characteristic values of the components of multiple subcontract work breakdown structures and the components of the general contractor work breakdown structure are determined. When the characteristic values of the components of the general contractor work breakdown structure are the same as those of the components of multiple subcontract work breakdown structures, the leaf nodes of multiple subcontract work breakdown structures are attached to the leaf nodes of the general contractor work breakdown structure to obtain a new tree structure. The new tree structure is unit project-divisional project-sub-project-general contractor list-subcontract list. The planned start time and the planned completion time are added to the leaf nodes of the new tree structure to obtain the detailed project schedule P. The leaf nodes of the subcontract work breakdown structure are subcontract list items, and the leaf nodes of the general contractor work breakdown structure are general contractor list items. The detailed project schedule P is: , the leaf nodes of P are ; Since it is too cumbersome to attach the leaf nodes of the subcontract work breakdown structure to the leaf nodes of the general contract work breakdown structure, the batch processing mechanism is used to treat the components with the same general contract list items and subcontract list items under the same subcontract contract as having the same characteristic values. Once some of the subcontract list items are attached to a general contract list item under a certain component, the components with the same characteristic values will be batch attached in the same way. For the first schematic diagram of attaching subcontracts to general contracts, please refer to Figure 2 ,like Figure 2 As shown, the subcontract work breakdown structure The first subcontract list item C011 of the intermediate component m001 is attached to the general contractor work breakdown structure When it comes to the following situation, it is determined that the component m002 also has a subcontracting item list C011 under the first subcontract. At this time, the subcontracting item list c011 under the subcontracted component m002 can be attached to the general contract item list m002 of the general contract component through batch processing. Since the general contract item list under the component m003 is c004 and does not include the general contract item list c001, the subcontracting item list c011 under the subcontracted component m003 cannot be attached through batch processing. For the second schematic diagram of subcontracting attached to the general contract, please refer to Figure 3 , such as Figure 3 shown, when attaching the subcontracting item lists c021, c021, and c023 under to the general contract item list of the component in , when the characteristic values of the general contract and subcontract components are the same, and the characteristic values of the subcontracting item lists of the subcontract are the same, batch processing is used for attachment. When the characteristic values of the subcontracting item lists are different, batch processing cannot be used for attachment.
[0025] In some embodiments, in step S103, the subcontract list items of the detailed project schedule are reported and measured to obtain the measured engineering quantity and measured amount of the EPC project. The measured engineering quantity is closely related to the project progress. The engineering quantity measurement is an important basis for project progress control. In engineering projects, the engineering quantity measurement refers to the process of accurately measuring, calculating and verifying the various engineering quantities in the project. This process is of great significance to the cost control, resource allocation and progress control of the project. Firstly, accurate engineering quantity measurement can provide an important basis for the project budget, thereby reasonably estimating and controlling the cost of the project and avoiding the cost overrun problem caused by inaccurate engineering quantity estimation. Secondly, the engineering quantity measurement can provide an important basis for the project budget, thereby reasonably estimating and controlling the cost of the project and avoiding the cost overrun problem caused by inaccurate engineering quantity estimation. Project quantity measurement can also help evaluate the construction progress and ensure that the project can be successfully completed according to the planned time nodes; project progress control is one of the key links in project management, which involves tracking, monitoring and adjusting the project progress. During the project execution process, regular project quantity measurement can grasp the progress of the project in real time and compare it with the planned progress, so as to find deviations and problems in time, which will help project managers take effective measures to make adjustments and ensure that the project can be smoothly carried out according to the predetermined schedule and milestone nodes; in addition, project quantity measurement also provides project managers with an important basis for formulating project schedules and conducting project risk assessments. Accurate project quantity information can help project managers more effectively Rationally arrange the construction sequence, allocate resources and formulate a schedule, so as to reduce project risks and improve the success rate of the project; fill in the subcontract list items of the project detailed schedule, and measure the subcontract list items after filling in, and obtain the measured engineering quantity and measured amount of the subcontract list items, specifically: determine the subcontract list items in the leaf nodes of the project detailed schedule, divide the project detailed schedule based on the subcontract contracts corresponding to the subcontract list items to determine the planned task list corresponding to the subcontracting unit, fill in the completion status of the subcontract list items based on the planned task list, and summarize the engineering quantity and output value corresponding to the subcontract list items to the leaf list items of the subcontract list items through downward measurement, and obtain the subcontract list items. The measured quantity and amount of the subcontract list items; when filling in the subcontract progress report, each subcontracting unit fills in the completion status of its own planned task items, queries the subcontract list items in all leaf nodes in the project detailed progress plan P, and divides P according to the subcontract contracts to which the subcontract list items belong. After the division, each subcontracting unit has its own planned task list Pn. The construction personnel of the subcontracting unit fill in the completion status of each subcontract list item of each component according to Pn. The completion status includes "unfinished" and "completed". According to the unit price, quantity, and total price corresponding to the subcontract list items under the component, the progress output value of the day is automatically calculated; when measuring downward, query each subcontract list item according to the start time and end time of the measurement period. The components associated with each leaf item in the list, and summarize the quantities and output values reported for the progress into each leaf item in the list, serving as the quantities and measurement amounts for the subcontract item list in this period. After obtaining the measured quantities and measurement amounts for the subcontract item list, summarize the measured quantities and measurement amounts for multiple subcontract item lists to obtain the measured quantities and measurement amounts for the general contract item list. Through upward measurement, summarize the measured quantities and measurement amounts for multiple general contract item lists, summarize the quantities and measurement amounts within the measurement period time segment, and then summarize to , forming the quantities and measurement amounts for upward measurement in this period to obtain the measured quantities and measurement amounts for the EPC project. When filling in the general contract progress, it is divided into two parts. One part is the general contract item list in Plan P that has not been split into other subcontract item lists. Such planned tasks are regarded as the part self-constructed by the general contractor unit. Therefore, manual filling is required according to the on-site construction. The other part refers to the general contract item list in Plan P that has been split into other subcontract item lists. These general contract item lists are regarded as having been constructed by the subcontractor unit. Therefore, the general contractor cannot fill in the form. The corresponding progress output value of the general contractor should be deduced based on the subcontract progress filling. For the specific deduction rules, please refer to Figure 4 , as Figure 4 shown, when all subcontract item lists under the general contract item list are in the completed state, the status of the general contract item list is completed. When the subcontract item list under the general contract item list is in the uncompleted state, the general contract item list is uncompleted; Calculate the upward measurement quantities and amounts within the time segment (sdate, edate). First, calculate the measured quantity of the leaf item of the general contract item list. The calculation formula for the measured quantity of the general contract item list is: , where is the measured quantity of the general contract item list, is the component of the project detailed progress plan, is the leaf item of the general contract item list, is the quantity, is the time segment; Secondly, calculate the measurement amount corresponding to the measured quantity of the leaf item of the general contract item list. The calculation formula for the measurement amount of the general contract item list is: , where is the measurement amount corresponding to the measured quantity of the general contract item list, is the unit price of the general contract item list; According to The measured amount is summed up level by level according to the tree structure of the general contractor's work breakdown structure, and finally the measured engineering quantity and amount of the EPC project can be obtained.
[0026] According to the measured engineering quantity and amount of the EPC project, the progress of the BIM model is statistically analyzed, including: statistics on the completion status of the components. When all the general package lists under the component are completed, the component is completed, otherwise it is not completed; statistics on the execution status of the component. If the current time is greater than the planned completion time of the component and the component is not completed, the component is delayed, otherwise it is normal.
