Description

Technical Field

[0001] The present invention relates to the technical field of project investment amount verification, and in particular to a settlement amount verification and analysis method based on progress milestones and contract lists. Background Art

[0002] In the field of engineering management, physical measurement is often used to calculate the settlement amount during the settlement of contract progress payments. For temporary projects or civil engineering projects with short construction periods that are difficult to measure, the contracting parties negotiate and estimate the settlement amount before settlement. Party A guarantees that the overall amount for each individual item does not exceed the contracted upper limit. However, physical measurement requires on-site measurement and confirmation of each work item in the contract list before contract settlement. Since the list of construction contracts is usually large, the on-site verification process is extremely cumbersome. This tedious measurement process requires a large investment of human resources, and the accuracy of the results is difficult to guarantee. For example, for EPC contracts or lump-sum projects, the use of physical measurement may result in differences between the results and the original quotation, leading to settlement disputes. This is not conducive to reducing ineffective investment by all parties involved in the construction and is detrimental to Party A's control over the contract cost.

[0003] Therefore, the present invention provides a settlement amount verification and analysis method based on progress milestones and contract lists. Summary of the Invention

In order to avoid information disorder, establish corresponding milestone items for each progress node, and then establish BOQ items according to the contract list. By matching the milestone items and BOQ items, the amount accounting items corresponding to each progress node are generated. The milestone items of the same BOQ item are further aggregated to generate the corresponding milestone group. The amount accounting items corresponding to the milestone group are calculated to determine the amount of each progress node. The contract stipulates the amount, and further determines the amount sharing ratio between different progress nodes based on the logical relationship between different milestone groups, thereby determining the legal amount range of each progress node. Finally, the legal range is used to analyze whether the actual settlement amount of the corresponding progress node is legal, and generate the corresponding accounting report. In this way, the tedious measurement process can be avoided. For lump-sum projects, settlement disputes caused by the difference between the physical quantity measurement results and the original quotation are avoided, which is beneficial for all parties involved in the construction to reduce invalid investment and for Party A to control the contract cost. It can also reflect the work progress and settlement amount at the same time, which is more suitable for the settlement of design contracts and procurement contracts themselves, and can establish a good relationship with the plan, making the cash flow calculation more in line with reality.

[0056] Other features and advantages of the present invention will be described in the following description, and in part will become apparent from the description, or will be understood by practicing the present invention.

[0061] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0062] Example 1

[0063] This embodiment provides a settlement amount verification and analysis method based on progress milestones and contract lists, such as Figure 1 As shown, including:

[0064] Step 1: Acquire real-time construction data of the construction site, establish a real-time construction progress of the construction site, identify several progress nodes of the real-time construction progress, and establish corresponding milestone items;

[0065] Step 2: Create several BOQ items based on the EPC contract list, match the milestone items with the BOQ items, and obtain several amount accounting items corresponding to each progress node;

[0066] Step 3: Create milestone groups for each BOQ item, and calculate the contract amount corresponding to the progress node based on the multiple amount accounting items corresponding to each milestone group;

[0067] Step 4: Determine the amount sharing ratio between corresponding progress nodes based on the logical relationship between different milestone groups, and determine the legal amount range for each progress node based on the contract amount corresponding to each progress node;

[0068] Step 5: Determine the actual settlement amount corresponding to each progress node based on the real-time construction data, generate and display a settlement report for each progress node based on the corresponding legal amount range.

[0069] In this example, real-time construction data refers to data generated during the construction process of a construction site;

[0070] In this example, the progress node represents the result of dividing the construction progress into segments, which is set in advance;

[0071] In this example, the real-time construction progress represents the sum of the current construction progress and the historical progress. Since the real-time construction progress is constantly changing, the progress nodes corresponding to different times are different.

[0072] In this example, the milestone item is a tool used to track key information in the progress node, and generally represents the construction time point corresponding to the progress node;

[0073] In this example, the EPC contract list is a document that details the work content, required materials, quantities, unit prices, description of the project, and relevant units of measurement at the construction site;

[0074] In this example, the BOQ item represents the result of integrating the quantity, specifications, unit price, and total price of materials, labor, equipment, and other resources required for construction of an item in the contract bill;

[0075] In this example, the amount accounting item represents the accounting item of construction expenditure included in a progress node;

[0076] In this example, the milestone group represents the result of aggregating all milestone items corresponding to a BOQ item;

[0077] In this example, the contract stipulated amount represents the investment amount for each progress node derived from the contract list;

[0078] In this example, the amount sharing ratio indicates the amount sharing ratio generated when the same amount is used at different progress nodes. For example, if progress node 1 requires 1.5 tons of cement and progress node 2 requires 2.5 tons of cement, then when progress node 1 needs to purchase cement, the cement required by progress node 2 is also purchased at the same time. The amount sharing ratio between progress node 1 and progress node 2 for cement is: 1.5 / (1.5+2.5):2.5 / (1.5+2.5);

[0079] In this example, the legal amount range indicates the legal range of the actual settlement amount of a progress node;

[0080] In this example, the accounting report shows the actual settlement amount of a progress node and the evaluation of whether the actual settlement amount is legal.

[0081] In this example, the construction site refers to an area where construction is being carried out.

[0082] The working principle and beneficial effects of the above technical solution: In order to construct a construction investment accounting method that can reflect the contract quotation, reflect the work progress, and can organically combine the contract settlement with the work progress, first establish the real-time construction progress of the construction site based on the real-time construction data of the construction site, and determine the progress nodes corresponding to the progress. In order to avoid information disorder, establish corresponding milestone items for each progress node, and then establish BOQ items based on the contract list. By matching the milestone items and BOQ items, the amount accounting items corresponding to each progress node are generated. The milestone items of the same BOQ item are further aggregated to generate the corresponding milestone group. The amount accounting items corresponding to the milestone group are calculated to determine the amount accounting items of each progress node. The contract stipulates the amount, and further determines the amount sharing ratio between different progress nodes based on the logical relationship between different milestone groups, thereby determining the legal amount range of each progress node. Finally, the legal range is used to analyze whether the actual settlement amount of the corresponding progress node is legal, and generate the corresponding accounting report. In this way, the tedious measurement process can be avoided. For lump-sum projects, settlement disputes caused by the difference between the physical quantity measurement results and the original quotation are avoided, which is beneficial for all parties involved in the construction to reduce invalid investment and for Party A to control the contract cost. It can also reflect the work progress and settlement amount at the same time, which is more suitable for the settlement of design contracts and procurement contracts themselves, and can establish a good relationship with the plan, making the cash flow calculation more in line with reality.

[0083] Example 2

[0084] Based on Example 1, the settlement amount verification and analysis method based on progress milestones and contract lists, step 1, includes:

[0085] Step 11: Acquire real-time construction data of the construction site, construct a real-time construction model of the construction site in a preset virtual space based on the real-time construction data, deduce the overall construction project of the construction site based on the real-time construction model, and traverse the real-time construction model using the overall construction project to obtain a number of constructed sub-projects;

[0086] Step 12: Sort the constructed sub-projects, establish a real-time construction progress of the construction site based on the project end time corresponding to each constructed sub-project, obtain the completed results corresponding to each constructed sub-project in the real-time construction model, locate each completed result in the real-time construction progress, and obtain a number of progress nodes;

[0087] Step 13: Identify the progress event of each progress node and establish an event attribute, identify the progress moment corresponding to each progress node and establish a moment attribute, and establish a milestone item corresponding to the progress node according to the event attribute and the moment attribute.

[0088] In this example, the preset virtual space represents a virtual three-dimensional space;

[0089] In this example, the overall construction project represents all the construction projects that need to be carried out to produce the results presented after the construction site is completed;

[0090] In this example, the constructed subproject represents a completed construction project;

[0091] In this example, the project termination moment is the moment when a constructed project is completed;

[0092] In this instance, constructed results represent the results presented after completing a constructed project;

[0093] In this example, a progress event represents an event completed by a progress node, and an event attribute represents an attribute corresponding to a progress event.

[0094] The working principle and beneficial effects of the above technical solution are as follows: by constructing a real-time construction model of the construction site to analyze the overall construction project of the construction site, and then sorting the constructed sub-projects to determine the real-time construction progress of the construction site, and further determining the corresponding progress nodes based on the construction results of each constructed sub-project, and then summarizing the moment attributes and event attributes corresponding to the progress event of each progress node to construct a milestone item for each progress node. In this way, a progress node segment suitable for this construction site can be constructed, and corresponding milestone items can be set for it, so that the allocation of each progress node and the allocation of milestone items are in line with the actual situation of the construction site, and subsequent settlement and verification can be better carried out.

[0095] Example 3

[0096] Based on Example 1, the settlement amount verification and analysis method based on progress milestones and contract lists, step 2, includes:

[0097] Step 21: Obtain the EPC contract list, determine several expenditure item information for the construction site, calculate the unit price and quantity of each expenditure item information, obtain several BOQ amounts for the construction site, and obtain the expenditure characteristics corresponding to each expenditure item information to obtain several BOQ types for the construction site;

[0098] Step 22: Create several BOQ items for the construction site based on the BOQ amount and BOQ type corresponding to the same expenditure item information, determine the construction event corresponding to the progress node based on the milestone item, build a material consumption list for the construction site based on the event expenditure corresponding to each construction event, map each BOQ item to the material consumption list, and obtain several material consumption information corresponding to each BOQ item;

[0099] Step 23: Mark each material consumption information in the real-time construction progress, determine the overlap relationship between each BOQ item and the milestone item based on the progress node corresponding to each material consumption information, generate multiple project matching pairs, and count the multiple BOQ amounts and multiple construction events included in each project matching pair;

[0100] Step 24: Determine the project expenditure cost corresponding to the progress node based on the multiple BOQ amounts included in each of the project matching pairs, determine the project progress speed corresponding to the progress node based on the multiple history events included in each of the project matching pairs, and establish the amount accounting item corresponding to the progress node based on the project expenditure cost and the project progress speed.

[0101] In this example, the expenditure item information represents expenditures at the construction site;

[0102] In this example, the BOQ amount represents the total amount of all work items on the construction site;

[0103] In this example, BOQ types include: traditional BOQ, simplified BOQ, detailed BOQ, BOQ classified by project stage, measurement BOQ, abstract BOQ, comprehensive BOQ, material BOQ, quantity adjustment BOQ and standard BOQ;

[0104] In this example, the material consumption list represents a statistical table of materials consumed by an event expenditure. For example, an expenditure event is: lawn mowing, and the materials consumed include: grass seeds, planting tools, and soil;

[0105] In this example, the item matching pair represents the result of matching a BOQ item and a milestone item having an overlapping relationship.

[0106] The working principle and beneficial effects of the above technical solution are as follows: by decomposing the contract list of the construction site, several expenditure items of the construction site are determined. Then, based on the unit price and quantity of each expenditure item, the BOQ amount of the construction site is established. At the same time, several BOQ types of the construction site are determined to generate corresponding BOQ items. Then, the material consumption of the construction site is analyzed to determine the material consumption information of the BOQ item. Each material consumption information is further analyzed in the real-time construction progress. Milestone information with the same milestone attributes are aggregated to construct a milestone information set for the BOQ item. The overall construction results of the BOQ item are further analyzed and the corresponding relationship between the milestone items and the amount accounting items is combined to construct the amount accounting item. The transaction transactions are further integrated to avoid the phenomenon of multiple calculations for the same transaction. The valid transactions of each BOQ item are determined. Finally, a visual map of the transaction transactions is created to determine the contract amount of the progress node. In this way, the relationship between the BOQ items and the milestone items can be deeply analyzed to determine the valid transactions of the construction and the contract amount corresponding to each progress node. This method can ensure the accuracy of the contract amount and improve the effectiveness of subsequent settlement and verification work.

[0107] Example 4

[0108] Based on Example 1, the settlement amount verification and analysis method based on progress milestones and contract lists, step 4, includes:

[0109] Step 41: Generate a sequence matching rule based on the corresponding sequence of different milestone items, obtain the starting point information and the end point information of each milestone item, and determine the project association rule between different milestone items based on the end-start point overlap characteristics between different milestone items;

[0110] Step 42: Establishing a logical relationship between milestone groups based on the sequence matching rule and the project association rule, analyzing the group sharing amounts between different milestone groups based on the logical relationship, establishing the item sharing amounts between different milestone items using the project association rule, and generating the amount sharing ratio between corresponding progress nodes based on the group sharing amounts and the item sharing amounts;

[0111] Step 43: Establish an amount data axis for each progress node based on the contract amount corresponding to each progress node, calculate the shared amount using the amount sharing ratio corresponding to each progress node and the corresponding contract amount, mark the calculation result in the corresponding amount data axis, and generate a legal amount range corresponding to each progress node.

[0112] In this example, the relationship between BOQ items, milestone items and milestone groups is as follows: Figure 2 As shown, the contract BOQ is the BOQ item of the present invention;

[0113] In this example, the order matching rule represents a rule for arranging milestone items in order of progress;

[0114] In this example, the project association rule represents a rule for arranging milestone items with association relationships;

[0115] In this instance, the group shared amount represents the amount that can be shared within a milestone group;

[0116] In this example, the item shared amount represents an amount that can be shared by two or more milestone items.

[0117] The working principle and beneficial effects of the above technical solution: In order to further determine the legal amount range of different progress nodes and improve the intelligence of accounting work, the logical relationship between milestone groups is generated by analyzing the sequential matching rules and project association rules between different milestone items, so as to determine the group sharing amount between different milestone groups and the item sharing amount between different milestone items, and the amount sharing ratio between different progress nodes is determined according to the relationship between the group sharing amount and the item sharing amount, so as to make corresponding adjustments to the corresponding contract amount, and determine the legal amount range of each progress node. In this way, a legal amount range can be matched for each progress node, which fundamentally avoids the impact of amount fluctuations caused by uneven sharing between different progress nodes on the verification results, and improves the user experience.

[0118] Example 5

[0119] Based on Example 1, the settlement amount verification and analysis method based on progress milestones and contract lists, step 5, includes:

[0120] Step 51: Acquire a real-time construction image of the construction site, establish a plurality of construction dynamics of the construction site based on the real-time construction data, map the construction dynamics into the real-time construction image, and generate a dynamic construction model of the construction site;

[0121] Step 52: Run the dynamic construction model to obtain the material consumption details corresponding to each progress node, determine the actual settlement amount corresponding to each progress node, and determine the effective settlement amount corresponding to each progress node based on the contract amount and legal amount range corresponding to each progress node;

[0122] Step 53: Calculate and evaluate the corresponding actual settlement amount based on the effective settlement amount, obtain the settlement legal details corresponding to each progress node, generate and display the corresponding accounting report.

[0123] In this example, the dynamic construction model refers to a real-time construction model with dynamic presentation.

[0124] The working principle and beneficial effects of the above technical solution utilize real-time construction images and real-time construction data of the construction site to establish a dynamic construction model of the construction site, thereby determining the material consumption details of the progress nodes and clarifying the actual settlement amount of each progress node. At the same time, the effective settlement amount of the progress node is determined based on the contract amount and the legal amount range, thereby analyzing the legality of the actual settlement amount based on the effective settlement amount and making a corresponding accounting report. Users can understand the investment situation of each progress node by referring to the accounting report, helping users make different investment decisions.

[0125] Example 6

[0126] Based on Example 4, the settlement amount verification and analysis method based on progress milestones and contract lists further includes:

[0127] Determine the hierarchical relationship between different milestone items in each milestone group according to the logical relationship, and establish a corresponding classification code for each milestone item based on the hierarchical relationship;

[0128] Determining the subordinate shared attributes corresponding to each milestone item using the hierarchical order corresponding to the hierarchical code;

[0129] The sharing ratio of the milestone group is set to 1, and a corresponding sharing ratio is assigned to each milestone item based on the subordinate sharing attribute corresponding to each milestone item. The item sharing amount corresponding to each milestone item is determined in combination with the corresponding group sharing amount.

[0130] In this example, the hierarchical code represents a distinguishing code established according to the progressive relationship between different milestone items;

[0131] In this example, the "lower-level sharing" attribute indicates that the amount of a milestone item (a higher-level milestone item) can be shared with the next lower-level milestone item (a lower-level milestone item). Conversely, a lower-level milestone item cannot share amounts with the higher-level milestone item. For example, if Milestone A is building a swimming pool and Milestone B is tiling the pool, then Milestone A can share amounts with Milestone B.

[0132] In this example, the sharing ratio is set to 1 for the purpose of facilitating calculation.

[0133] The working principle and beneficial effects of the above technical solution: In order to better share the amount, a hierarchical code is established for the milestone item according to the hierarchical relationship of different milestone items in a milestone group, and the corresponding attributes are set for the milestone item according to the hierarchical order. Then, the group sharing amount is allocated according to the sharing ratio, and the item sharing amount of each milestone item is determined. In this way, a reasonable item sharing amount can be allocated to each milestone item.

[0134] Example 7

[0135] Based on Example 1, the settlement amount verification and analysis method based on progress milestones and contract lists further includes:

[0136] Determine the excess amount corresponding to each progress node according to the accounting report;

[0137] When the excess amount exceeds the prescribed limit, an alarm reminder message is generated and a corresponding alarm is issued.

[0138] In this example, the prescribed amount represents 1.5% of the eligible prescribed amount.

[0139] The working principle and beneficial effects of the above technical solution: an alarm will be issued when the settlement amount of a progress node is too high.

[0140] Example 8

[0141] Based on Example 7, the settlement amount verification and analysis method based on progress milestones and contract lists further includes:

[0142] Based on the dynamic construction model corresponding to the construction site at different construction times, a chart of the actual settlement amount of the construction site is generated and displayed.

[0143] The working principle and beneficial effects of the above technical solution: Generate a settlement amount chart for user reference, which can help users make the next decision.

[0144] Example 9

[0145] Based on Example 8, the settlement amount verification and analysis method based on progress milestones and contract lists further includes:

[0146] estimating the actual settlement amount of the construction site according to the actual settlement amount chart;

[0147] Calculate the planned investment amount for the construction site based on the contract amount corresponding to each progress node and the corresponding legal amount range;

[0148] A candidate investment amount is generated and displayed based on the difference between the actual settlement amount and the planned investment amount.

[0149] The working principle and beneficial effects of the above technical solution are: by generating a reserve investment quota, users are reminded to replenish funds to avoid insufficient funds.

Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
