Technical Field

[0001] The present application relates to the field of construction cost management, and in particular to a visual construction cost management method, system, equipment and medium based on BIM technology. Background Art

[0002] Before construction is carried out on contaminated land, the quality of the land needs to be tested. Construction can only be carried out when the quality of the land meets the safety standards. Before construction, although the content of polluting harmful substances in the land meets the safety standards, the content of harmful substances will change under the influence of the environment around the construction area. Once the content of harmful substances rises and exceeds the safety standards, it will not only affect the health of the construction workers, but also cause erosion and pollution to the structure of the building, causing the structure of the building to be unstable.

[0003] Therefore, in order to reduce the erosion and pollution of harmful substances, materials that reduce the spread of harmful substance pollution are usually installed at the location where the building contacts the land to protect the building and strengthen the building structure.

[0004] However, in the cost calculation for the exterior walls of buildings, the cost of the construction structural materials of the wall is generally calculated, and the cost of the materials used to protect the exterior walls of the building is ignored. If, when calculating the amount of protective materials, there is a lack of data on the usage and usage of protective materials, it is difficult to calculate and predict the cost of the protective materials. Summary of the invention

[0005] The first purpose of this application is to provide a visual engineering cost management method based on BIM technology, which can increase the cost calculation of protective materials used for building walls according to the building exterior wall information provided by BIM, and improve the accuracy of the overall cost calculation of the building.

The additional protective materials can avoid the problem of unstable building structure caused by erosion by harmful substances. At the same time, the distribution of protective materials is displayed through BIM technology, and the current cost of protective materials is calculated in combination with the latest cost quotation sheet, which improves the accuracy and reliability of the overall cost calculation of the building.

[0034] The following is combined with Figure 1-9 This application is described in further detail.

[0035] refer to Figure 1, a visual engineering cost management method based on BIM technology, specifically including: S1. Collect soil data within the building area, and train and generate a soil detection model for simulating the soil state of the building exterior wall based on the soil data.

[0036] Among them, field surveys are conducted in the construction area to collect soil samples at different depths and locations. Then the collected soil data is cleaned and sorted, including removing outliers and filling missing values, and the data is converted into a format suitable for machine learning model training, such as numerical and normalization processing, and then feature selection is performed. Through machine learning, the pre-processed soil data is divided into training sets and test sets, and the training set data is used to train and generate a soil detection model. The model parameters are adjusted through cross-validation and other techniques to optimize the model performance. The test set data is used to verify the prediction ability of the model and evaluate the accuracy and generalization ability of the model. The model parameters are adjusted according to the verification results, and the model is optimized to improve the prediction accuracy. Finally, the trained soil detection model is applied to the simulation of the soil state of the actual building exterior wall. According to the feedback in the actual application, new data is continuously collected, and the model is iterated and updated to improve the accuracy and practicality of the model.

[0037] S2. Based on BIM technology, the real-time soil data and building model are simulated in three dimensions. The soil quality at the bottom of the building's exterior wall is tested in real time through the soil detection model to determine whether the current building's exterior wall needs additional protective materials.

[0038] Among them, BIM technology is used to map the real-time collected soil data to the building model, update the soil parameters in the model, and then use three-dimensional simulation technology to visualize the soil state at the bottom of the building's exterior wall. The previously trained soil detection model is applied, and real-time soil data is input to simulate the dynamic changes of the soil at the bottom of the exterior wall. The soil detection model can output predictions including soil state and impact assessments on the building's exterior wall.

[0039] S3. If additional protective materials are needed, the distribution of the building’s protective materials will be displayed through BIM technology.

[0040] Among them, BIM technology can reflect the setting of protective materials in the building model, and then can concretely display the distribution of protective materials in the building model.

[0041] S4. Calculate the cost of obtaining protective materials for the building based on the distribution of protective materials and the latest cost quotation.

[0042] The distribution of protective materials in the building model can reflect the usage of protective materials. Then, through the latest cost quotation table, the types of protective materials distributed in the building model can be matched to calculate the cost of protective materials. Combining the cost of easily overlooked protective materials with the cost of other common materials can obtain the cost of the materials required for the entire building.

[0043] In this embodiment, the soil detection model is used to dynamically simulate the soil conditions at the bottom of the building's exterior wall to obtain real-time soil data, and the real-time soil data is combined with the building model using BIM technology to achieve real-time monitoring of the exterior wall soil environment, thereby timely assessing whether the building's exterior wall is affected by land pollution and erosion, and then determining whether additional protective materials are needed to enhance structural stability. The additional protective materials can effectively prevent erosion by harmful substances in the land and effectively avoid the problem of unstable building structures. At the same time, BIM technology can not only intuitively display the distribution of protective materials on the building's exterior wall, but also combine the latest cost quotation table to calculate the cost of easily overlooked protective materials, thereby improving the accuracy and reliability of the overall cost control of the building.

[0044] refer to Figure 2 Further, in one embodiment, step S1 is refined into the following sub-steps: S10. Acquire soil quality data of the raw land in the construction area, and divide the land in the construction area into several observation plots according to the main types of harmful substances. The several observation plots include the connection parts between the building exterior walls and the land.

[0045] Among them, the soil quality data of the raw land can reflect the distribution of harmful substances in the land before construction begins. Moreover, since the degree of decomposition of each harmful substance affected by humidity is different, it is necessary to classify the different harmful substances on the land. The obtained soil quality data can more accurately reflect the changes of harmful substances. Specifically, the acquisition of soil quality data of the raw land in the construction area is carried out in the early stage of project development before construction. Soil sampling points are deployed in the raw land in the construction area to ensure coverage of the entire area, especially the connection between the building exterior wall and the land. Then the collected soil samples are subjected to laboratory analysis to obtain the composition of harmful substances in the soil. According to the composition of the main types of harmful substances in the soil samples, the land in the construction area is divided into several observation plots. In addition, by maintaining the differences between the analysis plots, the distribution patterns and possible migration paths of harmful substances are identified, and the division of the observation plots is updated in real time.

[0046] S11. Obtain data on changes in the content of harmful substances in the land affected by humidity in several observation plots, train and generate soil quality detection models for the content of different types of harmful substances in the land affected by land humidity, so as to simulate the pollution state of harmful substances in the connection parts between the exterior walls of buildings and the land in several observation plots.

[0047] The soil moisture and the content of different types of harmful substances are recorded over a long period of time, and a soil quality detection model is trained and generated through a machine learning algorithm. The soil quality detection model is used to detect the soil quality of the connection between the building exterior wall and the land in each observation plot in real time, and output soil quality data.

[0048] In this embodiment, in the early stage of the development of the construction project, the soil data of the raw land in the construction area is obtained, and the land in the construction area is divided into multiple observation plots according to the main types of harmful substances, so as to accurately identify the soil data such as the main types of harmful substances and decomposition characteristics in each observation plot, and then combined with the harmful substance content change data of the land affected by humidity in each observation plot, a soil detection model for dynamically simulating the harmful substance pollution state of the connection part between the building exterior wall and the land in each observation plot is trained and generated. By using the soil detection model, it is helpful to timely discover potential harmful substance pollution risks, effectively avoid the erosion of the building exterior wall structure caused by excessive harmful substance content, thereby making the building safer and more stable, and can guide and provide specific locations where protective materials need to be added.

[0049] In addition, reference Figure 3 Further, in one embodiment, step S2 is refined into the following sub-steps: S20. Based on BIM technology, obtain the location information of the connection parts between the building exterior walls and the land in several observation plots in the building model.

[0050] Among them, the detailed location information of the connection between the building's exterior wall and the land is extracted from the building model created by BIM software, including coordinates, height, depth, etc.

[0051] S21. Through the soil detection model, the harmful substance content of the connection part between the building exterior walls and the land in several observation plots is detected in real time.

[0052] S22. If the content of harmful substances exceeds the safety standard threshold, it is confirmed that the current building exterior wall needs to be equipped with additional protective materials.

[0053] Among them, the safety standard threshold is mainly based on the "Soil Pollution Risk Control Standard Construction Land Soil Pollution Risk Screening Value (Trial)" (GB 36600-2018), or is set by the construction party itself, and the set value must be within the range of safe construction.

[0054] In this embodiment, when the harmful substance content detected by the soil detection model exceeds the safety standard threshold, timely feedback is given that the exterior walls of the buildings in the observed plot need to be equipped with additional protective materials, thereby effectively preventing the erosion of the exterior walls of the buildings by harmful substances, ensuring the safety and stability of the building structure, and adding the required cost of the protective materials for the exterior walls of the buildings, effectively avoiding the cost estimation errors caused by the missing data of the protective materials, thereby improving the accuracy of the overall project cost management.

[0055] In addition, reference Figure 4 Further, in one embodiment, step S3 is refined into the following sub-steps: S30: Obtain the type of the additional protective material.

[0056] Among them, the types of protective materials that have been set up in different observation plots in the past can be matched to the types of protective materials for the building exterior walls that currently need to be added with protective materials, and then after secondary confirmation by professionals, the final type of protective materials can be obtained.

[0057] S31. If the protective material is liquid paint applied to the exterior wall of the building, then according to the preset application height and the connection part between the exterior wall of the building and the land, the applied part of the liquid paint is covered to the exterior wall of the building model through BIM to calculate the estimated usage area of ​​the liquid paint.

[0058] Among them, liquid coatings based on the main types of harmful substances in the observed plot, with good protective performance, weather resistance, adhesion and other factors, should be selected to protect the exterior walls of buildings against the main types of harmful substances.

[0059] S32. If the protective material is a solid material installed on the exterior wall of the building, then based on the area of ​​the solid material and the connection between the exterior wall of the building and the land, the installation part of the solid material is covered to the exterior wall of the building model through BIM to calculate the estimated amount of solid material used.

[0060] Among them, solid materials should be selected based on their protective performance against harmful substances, durability, ease of installation, and compatibility with building exterior walls to protect building exterior walls against the main types of harmful substances.

[0061] In this embodiment, BIM technology is used to calculate the application of different protective materials on the building exterior walls according to different types of protective materials, providing a data basis for the cost estimation. Specifically, for liquid paint, BIM technology can visualize the location of liquid paint applied on the building exterior wall in the building model, thereby calculating the estimated area of ​​use; and for solid materials, BIM technology can accurately calculate the estimated amount of use, and also visualize the distribution of solid materials on the building exterior wall.

[0062] In addition, reference Figure 5 Further, in one embodiment, step S4 is refined into the following sub-steps: S40, calculating and estimating the usage of the liquid paint according to the usage area of ​​the liquid paint, and calculating the usage of the liquid paint through the latest cost quotation table to obtain the cost of the liquid paint.

[0063] Among them, the latest cost quotation sheet contains the latest unit cost price of liquid paint. By consulting the liquid paint product manual, the theoretical coverage rate of liquid paint per liter or barrel is obtained. Then, according to the area of ​​use of liquid paint, the amount of liquid paint used is estimated by the formula = area of ​​use of liquid paint / coating coverage rate, to estimate the amount of liquid paint used, and combined with the latest unit cost price of the corresponding liquid paint, the cost of liquid paint is calculated through the latest cost quotation sheet.

[0064] S41. Calculate the usage quantity of the solid materials using the latest cost quotation sheet to obtain the cost of the solid materials.

[0065] The latest cost quotation includes the latest unit cost of solid materials. Estimated cost of solid materials = quantity of solid materials used * latest unit cost of solid materials.

[0066] S42. Add the cost of the liquid coating and the cost of the solid material to obtain the cost of the building protection material.

[0067] When calculating the cost, the convolutional neural network algorithm and the reverse neural network algorithm are used together to identify the cost data. In addition, it is also possible to plan the optimal procurement cycle and economic batch of protective materials with BIM shared information, integrate data and make real-time predictions based on the grey principle, control the procurement cost of protective materials, combine project management with the cost control of the entire life cycle of the project, follow the principle of dynamic cost pre-control, optimize cost control measures, provide theoretical support for project cost management, and improve the reliability of cost data.

[0068] In this embodiment, the usage of liquid paint is estimated by calculating its usage area, and the cost of the liquid paint is calculated in combination with the latest cost quotation sheet. At the same time, the cost of the solid material is calculated based on the amount of solid material used, also using the latest cost quotation sheet. Finally, these two parts of the cost are added together, and the latest total cost calculation of the protective materials used for the exterior walls of the building, which are easily overlooked, is added, thereby improving the accuracy and reliability of the project cost calculation.

[0069] In addition, reference Figure 6Furthermore, in one embodiment, the following steps are added before step S11: S110. Use BIM technology to simulate the impact of different weather conditions on land humidity in several observation plots and obtain land humidity change data.

[0070] Among them, by introducing historical and real-time meteorological data, including rainfall, evaporation, temperature, humidity, etc., as input parameters of the simulation, and considering different weather conditions, such as sunny days, rainy days, high temperatures, low temperatures, etc., to evaluate their impact on land moisture. Then, the soil moisture balance model is used to simulate the dynamic changes of soil moisture. Then, the simulation is run in the BIM software to observe the changes in land moisture under different weather conditions, and the simulation parameters such as rainfall intensity and duration are adjusted in real time according to the actual situation to analyze its impact on soil moisture. Next, the land moisture data during the simulation process is collected, including the changes in soil moisture at different depths, and the changing trends and patterns of land moisture under different weather conditions are identified.

[0071] S111. Based on the land humidity change data, a humidity detection model for detecting land humidity is trained and generated to obtain the land humidity of several observation plots in real time.

[0072] In this embodiment, through the integrated application of BIM technology, the change data of land humidity is obtained based on the weather conditions of several observation plots. The trained and generated humidity detection model can provide real-time humidity data of the land for the soil detection model, thereby improving the accuracy of predicting the changing trend of the harmful substance content, so as to identify possible pollution risks in advance and try to avoid damage to the building structure caused by excessive harmful substances.

[0073] In addition, reference Figure 7 Further, in one embodiment, step S21 is refined into the following sub-steps: S210. Using a soil quality testing model, predict the changing trend of the harmful substance content in the connection between the building exterior walls and the land in several observation plots at the next time node due to the influence of soil humidity.

[0074] Among them, the current land moisture data and the predicted humidity change trend are input into the soil detection model and the model is run to predict the change in the content of harmful substances at the next time node.

[0075] S211. If the content of harmful substances changes dramatically due to the influence of soil moisture, a pollution alarm will be issued to remind the installation of additional protective materials.

[0076] Among them, pollution alerts are sent to the mobile terminals of relevant personnel, enabling them to promptly add protective materials to the exterior walls of buildings that pose pollution risks.

[0077] In this embodiment, for the trend of a sharp increase in the content of harmful substances in the connection part of the building's exterior wall and the land, an early warning of possible pollution risks can be issued in time to remind relevant personnel to take measures to add protective materials, effectively avoid the problem of building structure erosion caused by a sharp increase in the content of harmful substances, and improve the safety and stability of the building. At the same time, through early pollution warning, the construction plan can be reasonably arranged to reduce the risk of construction delays and cost increases due to sudden pollution.
