That is, the obtained project cost not only includes the total cost evaluated according to the engineering drawings, but also includes the additional costs required during the construction of the project to be evaluated, so that the cost of the project to be evaluated is more in line with the actual situation, thereby improving the accuracy of the project cost evaluation.

[0047] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0048] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0049] The main solution of the embodiment of the present application is: after receiving the engineering cost evaluation instruction, the equipment capable of realizing the engineering cost obtains the engineering drawings of the project to be evaluated; then the engineering drawings are input into a preset cost evaluation model to obtain the engineering cost of the project to be evaluated, and the preset cost evaluation model is obtained by training the to-be-trained model based on annotated historical engineering drawings, and the annotated historical engineering drawings are historical engineering drawings that are annotated with additional costs that will be incurred during the construction process according to actual working conditions.

[0050] In this embodiment, for the convenience of description, the following description is made with the equipment capable of realizing the engineering cost as the execution subject.

[0051] In order to ensure the accuracy of the project cost, the existing technology usually combines the design requirements of the project and the design scheme as the basis to calculate the project cost according to different design schemes in order to select a more reasonable construction scheme and the best design scheme. However, due to external factors, the construction site cannot be strictly constructed according to the construction scheme. Therefore, even if a reasonable construction scheme is determined according to the design scheme, the accuracy of the project cost will decrease due to the actual construction situation.

[0052] The present application provides a solution, which is to obtain the engineering drawings of the project to be evaluated after receiving the evaluation instruction of the project cost, so as to use the preset cost evaluation model to evaluate the engineering cost of the project to be evaluated corresponding to the engineering drawings according to the engineering drawings. Since the preset cost evaluation model is combined with the waste consumption required by the actual working conditions during training, when the project cost is evaluated by the preset cost evaluation model, the additional costs that will be required during the construction of the project to be evaluated will be evaluated to obtain the project cost of the project to be evaluated. That is, the obtained project cost not only includes the total cost evaluated according to the engineering drawings, but also includes the additional costs required during the construction of the project to be evaluated, so that the cost of the project to be evaluated is more in line with the actual situation, thereby improving the accuracy of the project cost evaluation.

[0053] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device that can realize the above functions, a device that can realize the engineering cost, etc. The following takes the device that can realize the engineering cost as an example to illustrate this embodiment and the following embodiments.

[0054] Based on this, the present application embodiment provides a method for evaluating the construction cost. Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for evaluating the construction cost of the present application.

[0055] In this embodiment, the project cost assessment method includes steps S10 to S20:

[0056] Step S10, after receiving the engineering cost evaluation instruction, obtaining the engineering drawings of the project to be evaluated;

[0057] It should be noted that the evaluation instruction can be a start instruction for starting the cost evaluation of the project to be evaluated. After receiving the instruction, the equipment capable of realizing the project cost obtains the engineering drawings of the project to be evaluated, so as to perform the cost evaluation of the project to be evaluated based on the engineering drawings. The project to be evaluated can be a construction project that has not yet started construction, or a construction project under construction. The engineering drawings can be the design drawings of the project to be evaluated. In the project cost evaluation, the engineering drawings provide the necessary basic data and details to ensure the accuracy and comprehensiveness of the evaluation, wherein the design drawings can be the original design drawings of the project to be evaluated, or they can be the design drawings modified from the original design drawings during the construction process of the project to be evaluated. The engineering drawings contain all the detailed information of the project to be evaluated, including but not limited to building materials, structural design, construction technology, etc.

[0058] In a specific implementation, after receiving the instruction, the device capable of realizing project cost estimation displays an interface for obtaining engineering drawings on the display interface of the device. The user searches for engineering drawings corresponding to the project to be evaluated through the engineering drawings or the drawing database of the device, and retrieves the engineering drawings from the drawing database of the device to facilitate the subsequent use of the model to perform cost estimation on the project to be evaluated based on the engineering drawings.

[0059] Step S20, input the engineering drawings into a preset cost assessment model to obtain an engineering cost for evaluating the project to be evaluated, wherein the preset cost assessment model is obtained by training the model to be trained based on annotated historical engineering drawings, and the annotated historical engineering drawings are historical engineering drawings that are annotated with additional costs that will be incurred during the construction process based on actual working conditions.

[0060] It should be noted that the additional costs in the annotated historical engineering drawings provide important reference data for training the cost assessment model, so that the preset cost assessment model can combine the additional costs incurred during the actual construction process when evaluating the cost of the working condition to be evaluated, thereby improving the prediction accuracy. Additional costs refer to the costs that exceed the budget due to various reasons during the construction process, as well as the costs that need to be wasted during the construction process. The preset cost assessment model can be a machine learning model built based on historical data, such as a random forest or neural network model.

[0061] Among them, the various reasons may be design changes, material price fluctuations, changes in construction personnel or changes in construction personnel's wages, etc., which shall be determined based on actual conditions.

[0062] Among them, the costs that need to be wasted may include the bricks at the construction site that are often used as pads for the cart during the construction process to prevent the cart from sliding down the slope. In this case, the cost of the bricks used as pads is an additional expense; or the engineering drawings show that three wires of a certain type are required to bundle two vertical steel bars. However, in the actual construction process, four or five wires of a certain type may be required due to some safety factors. The cost of the extra wires is an additional expense, etc.

[0063] It is understandable that since the preset cost assessment model is trained based on annotated historical engineering drawings, these annotated historical engineering drawings contain additional cost information under actual working conditions, so that the preset cost assessment model can take into account various actual possible situations when conducting cost assessment of the project to be assessed. That is, when encountering similar special construction conditions, the preset cost assessment model can refer to historical data to accurately estimate the additional costs, rather than simply calculating the cost based on standard engineering materials and processes, thereby improving the accuracy of the project cost assessment.

[0064] It is understandable that after receiving the evaluation instruction, the engineering drawings can be quickly obtained and input into the preset model to obtain the project cost, which reduces the tedious steps of manually searching for information, analyzing various special situations, etc., and thus improves the evaluation efficiency.

[0065] It is understandable that the use of deep learning models to analyze engineering drawings can more objectively and accurately identify factors that may lead to additional costs, thereby improving the accuracy of the preset cost assessment model in assessing the cost of the project to be assessed.

[0066] The present embodiment provides a method for evaluating a project cost. After receiving an evaluation instruction for the project cost, the engineering drawings of the project to be evaluated are obtained, and the engineering cost of the project to be evaluated corresponding to the engineering drawings is evaluated based on the engineering drawings using a preset cost evaluation model. Since the preset cost evaluation model is combined with the waste consumption required by actual working conditions during training, when evaluating the project cost using the preset cost evaluation model, the additional costs that will be required during the construction of the project to be evaluated will be evaluated to obtain the project cost of the project to be evaluated. That is, the obtained project cost includes not only the total cost evaluated according to the engineering drawings, but also the additional costs required during the construction of the project to be evaluated, so that the cost of the project to be evaluated is more in line with the actual situation, thereby improving the accuracy of the project cost evaluation.

[0067] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 Before step S10, the project cost evaluation method further includes steps S01 to S03:

[0068] Step S01, obtaining historical engineering drawings and cost details, wherein the cost details are details of the cost of the historical engineering corresponding to the historical engineering drawings during the construction process;

[0069] Step S02, based on the cost details, marking the engineering areas that need to incur additional costs during the construction process in the historical engineering drawings;

[0070] Step S03: training the model to be trained based on the historical engineering drawings that mark the engineering area to obtain a preset cost assessment model.

[0071] It should be noted that historical engineering drawings are design drawings of completed engineering projects. Historical engineering drawings describe in detail various parts of the engineering project, including but not limited to the building structure, electrical system, water supply and drainage system, etc. They are usually presented in two-dimensional or three-dimensional form and contain various symbols and annotations to indicate specific construction requirements and material specifications. Cost details refer to the detailed records of all engineering-related expenses during the construction of the project. These expenses may include material costs, labor costs, machinery and equipment usage fees, additional construction measures costs (such as foundation reinforcement, earthquake prevention measures, etc.), and other unforeseen expenses (such as work stoppage losses due to weather, etc.). Each expense has a detailed description and amount. The engineering area is the area on the historical engineering drawings that represents the need to incur additional costs during the construction process. This area can be part of the building structure (such as foundation, wall, roof, etc.), or a specific functional area (such as office, conference room, warehouse, etc.), or a part of each construction step.

[0072] It can be understood that through a large number of historical engineering drawings and their corresponding actual engineering cost details, the collected engineering drawings are digitized and the parts that may incur additional costs during the construction process are marked for subsequent model training, so that the preset cost assessment model obtained by training can learn to identify features from engineering drawings that may lead to additional costs, so as to ensure that the final preset cost assessment model has the ability to identify additional costs.

[0073] Furthermore, step S02 further includes:

[0074] Based on the cost details, simulating the construction process of the historical project corresponding to the historical project drawing;

[0075] Based on the construction process, the cost details are divided into effective cost details and additional cost details, wherein the effective cost details are effective cost details of the necessary process for building the historical project, and the additional cost details are cost details that need to be wasted in building the historical project;

[0076] Determining the association relationship between the effective fee details and the additional fee details;

[0077] Based on the association relationship, the engineering area that needs to incur additional costs is marked in the historical engineering drawings.

[0078] It should be noted that effective cost details refer to the reasonable costs required to complete the necessary processes of the construction project, that is, the inevitable and reasonable expenses in the project implementation process, such as material procurement, labor wages, machinery rental, etc. Extra cost details refer to the unexpected costs caused by abnormal factors during the construction process, the costs that need to be wasted in addition to the effective costs, and unnecessary or avoidable costs. The correlation relationship refers to the connection and mutual influence between the effective cost details and the extra cost details. By analyzing the correlation relationship, we can better understand which factors may lead to additional costs, and optimize future project management and cost control strategies accordingly.

[0079] It can be understood that by dividing the consumption details into effective cost details and additional cost details and determining the correlation between them, the model to be trained can be trained more accurately, so that the final preset cost assessment model can more accurately identify the characteristics corresponding to the additional costs, thereby improving the accuracy of the project cost assessment.

[0080] It can be understood that by simulating the construction process of historical projects and marking the project areas that require additional costs, the ability of the preset cost assessment model to identify the characteristics corresponding to the additional costs can be improved.

[0081] Furthermore, the step of simulating the construction process of the historical project corresponding to the historical project drawing based on the consumption details includes:

[0082] Identify the purpose of each expense from the expenditure details;

[0083] Simulate the ideal construction steps of the corresponding historical project based on historical engineering drawings;

[0084] Based on the ideal construction steps, screening from the uses additional steps needed to assist the ideal construction steps;

[0085] After integrating the ideal construction steps with the additional steps, the construction process of the historical project is obtained.

[0086] It should be noted that the purpose of the cost is the specific purpose of each cost in a specific project or the corresponding project link. It is obtained by analyzing and identifying the relevant information of each cost in the cost details, and is used to clarify the relationship between each cost and various aspects of the project construction. For example, in a construction project, the purpose of a steel purchase cost may be to build the frame structure of a building. This purpose is determined based on the understanding of the project construction process and the characteristics of steel and the common use parts in the building. The ideal construction steps are based on the engineering drawings. According to the general logic and best practices of engineering construction, the construction process sequence of the project without unexpected interference is inferred, that is, an idealized construction process model, covering the sequence of major stages and links from the initial preparation to the final completion of the project. Each step corresponds to the structure, layout and other elements in the engineering drawings. The additional steps are steps that are found in the process of analyzing the purpose of costs based on the ideal construction steps to assist the ideal construction steps, which are not part of the ideal construction steps themselves but have a supporting or supplementary role in the project construction. The additional steps may be caused by special project requirements, external environmental factors or temporary problem solutions.

[0087] It is understandable that since the additional costs are temporarily incurred based on the construction site and are not costs incurred based on the ideal construction steps obtained based on the engineering drawings, in order to obtain the details of the additional costs, it is necessary to identify the purpose of each cost based on the consumption details, and to filter out the additional steps required to assist the ideal construction steps from the purposes based on the ideal construction steps, so as to ensure that the model to be trained can accurately identify the additional steps.

[0088] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. Figure 3 After step S20, the project cost evaluation method further includes steps S1 to S3:

[0089] Step S1, obtaining the completed work section information of the project to be evaluated;

[0090] Step S2, optimizing the preset cost evaluation model based on the work section information to obtain an optimized cost evaluation model;

[0091] Step S3, re-evaluating the unfinished sections in the project to be evaluated based on the optimized cost evaluation model to obtain the latest project cost.

[0092] It should be noted that the work section information is the detailed information of each completed construction stage in the project to be evaluated, including but not limited to the completed workload, materials used, labor invested, construction time, and any cost and progress information related to the completed work section. Unfinished work sections refer to the construction stages that have not yet started or are in progress in the project to be evaluated. The cost evaluation of this work section can be carried out based on the optimized cost evaluation model to timely predict the cost required to complete these work sections according to actual conditions. The latest project cost refers to the updated cost estimate of the entire project obtained after re-evaluating the unfinished work sections. This estimate includes the actual cost of the completed work sections and the predicted cost of the unfinished work sections, providing a more accurate forecast of the total cost of the project.

[0093] It is understandable that the completed work section information of the project to be evaluated is first obtained, and then the work section information is input into the preset cost evaluation model as new training data to optimize the model so that it can more accurately reflect the actual situation of the current project.

[0094] It is understandable that the optimized model is called the optimized cost assessment model. The optimized model (optimized cost assessment model) is used to re-evaluate the unfinished sections of the project to obtain the cost assessment that best fits the current project, further improving the accuracy of the project cost assessment.

[0095] It is understandable that the preset cost assessment model is constantly updated and optimized during the project. As the project progresses and new data is introduced, the assessment results can be updated in real time to obtain a more realistic cost assessment in real time, thereby improving the accuracy of the assessment.

[0096] Furthermore, step S2 further includes:

[0097] Extracting construction information of the construction user who constructs the project to be evaluated from the work section information;

[0098] identifying the construction habits of each of the construction users from the construction information;

[0099] The preset cost assessment model is optimized based on the construction practice to obtain an optimized cost assessment model.

[0100] It should be noted that construction users are individuals or teams involved in the construction of the project to be evaluated, including but not limited to contractors, subcontractors, construction teams or any entities directly involved in construction activities. Construction information refers to data and information related to the specific operations and activities of construction users during the construction process, including construction methods, construction sequence, construction efficiency, problems encountered during construction and their solutions, construction personnel's skill level and the use of construction equipment, etc. Construction habits are relatively fixed construction methods, processes and behavior patterns formed by construction users in long-term construction practice. Such habits may include specific construction technology preferences, material usage habits, construction rhythm control, safety and quality management habits, etc.

[0101] It can be understood that by optimizing the preset cost assessment model using the construction user's construction habit information, the preset cost assessment model can be made closer to reality, and personalized assessments can be performed based on the construction habits of different construction users, thereby improving the accuracy of the preset cost assessment model in assessing project costs.

[0102] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the method for evaluating the project cost of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0103] This application also provides a device for evaluating construction cost, please refer to Figure 4 , the project cost assessment device comprises:

[0104] The first acquisition module 10 is used to acquire the engineering drawings of the project to be evaluated after receiving the evaluation instruction of the project cost;

[0105] The evaluation module 20 is used to input the engineering drawings into a preset cost evaluation model to obtain the engineering cost of the project to be evaluated. The preset cost evaluation model is obtained by training the model to be trained based on annotated historical engineering drawings. The annotated historical engineering drawings are historical engineering drawings that are annotated with additional costs that will be incurred during the construction process based on actual working conditions.

[0106] Optionally, the second acquisition module 30 is used to acquire historical engineering drawings and cost details, wherein the cost details are details of the cost of the historical engineering corresponding to the historical engineering drawings during the construction process;
