[0002] With the rapid development of the construction industry, the scale of construction projects is becoming increasingly large, and data management and analysis during the construction process have become the key to improving project efficiency and ensuring project quality. However, traditional construction management methods often rely on manual records and experience judgments, and there are problems such as untimely data updates, serious information islands, and single analysis methods, which make it difficult to cope with complex and changing construction environments.

BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Figure 1 It is a schematic diagram of the working steps of the construction data processing method of the building engineering based on BIM technology of the present invention. DETAILED DESCRIPTION

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] See also Figure 1 The present invention provides a method for processing construction data of a building project based on BIM technology, comprising:

[0060] Step 1: Obtain construction site data in real time, integrate the BIM model with on-site IoT devices, and establish a construction management database;

[0061] The specific steps of step one are as follows:

[0062] Utilize IoT technology, use sensors, RFID tags, drones and other equipment to collect real-time construction data such as project progress records, quality scoring standard tables, safety risk scoring tables, cost record tables, etc. at the construction site; integrate the BIM model with the data collected by IoT devices to establish a unified construction management database.

[0063] Step 2: Extract historical construction data from the construction management database and calculate the construction progress forecast completion amount y based on the historical construction data t ;

[0064] The specific steps of step 2 are as follows:

[0065] Historical construction data at least includes the actual observation value y t-i ; Through the actual observation value y t-i Calculate the construction progress forecast completion amount y t , the formula is as follows:

[0066]

[0067] Among them, y t is the predicted completion amount of the construction progress at time point t, c is a constant term, which means that when the past observation value and the prediction error are both 0, the predicted value y t The basic level of φ ranges from -10 to 10; i is the autoregressive coefficient, which is used to measure the past observations y t-i For the current predicted value y t The influence degree of y is in the range of -1 to 1; t-i is the actual observed value at a past time point, θ i is the moving average coefficient, which is used to measure the past forecast error ∈ t-i For the current predicted value yt The influence degree of is in the range of -1 to 1; t-i It represents the difference between the actual observed value and the predicted value at time point ti, and the value can be any real number.

[0068] It should be noted that this formula predicts the construction progress at current and future time points based on the ARIMA model, where p is the number of autoregressive terms and q is the number of moving average terms.

[0069] The actual observed value y t-i It refers to the actual amount of work completed at the time point ti, i represents the lag at the time point, and the value is a positive integer; the construction progress forecast completion amount y t It refers to the predicted value of the construction progress completion at time point t. For example, suppose we have a construction project called "XX Building" which is scheduled to be completed within 24 months. Assuming that it is the fourth month of the project, we can predict the construction progress of the fourth month by combining the construction progress data recorded once a month.

[0070] Among them, time point t is the fourth month of the project, that is, t = 4; the actual observation value y t-i is the actual workload completed in the first three months of the project, y t-1 is the actual construction progress in the third month, y t-2 is the actual construction progress in the second month, y t-3 It is the actual construction progress in the first month.

[0071] Combined with the content of step 2: By integrating the actual observations in the historical construction data and using the complex algorithm of the ARIMA model, the time series characteristics and periodic changes in the construction progress can be captured more accurately. The accuracy of the construction progress forecast is effectively accelerated through the autoregressive coefficient and the moving average coefficient. Accurate construction progress forecast provides an important basis for construction management. Project managers can identify potential delay risks in advance based on the forecast results and take corresponding preventive and corrective measures.

[0072] Step 3: Extract the actual completion amount Sl of the construction progress from the construction management database, and calculate the actual completion amount Sl and the predicted completion amount y t The progress delay rate Jy is calculated; a progress delay threshold set JDy is preset, and the current construction progress status is evaluated based on the comparison result between the progress delay threshold set JDy and the progress delay rate Jy, and the corresponding early warning strategy level is matched based on the current construction progress status, and the corresponding early warning measures are selected and executed;

[0073] The specific steps of step three are as follows:

[0074] Step 301: The formula for calculating the schedule delay rate Jy is as follows:

[0075]

[0076] It should be noted that this formula is used to measure the difference between the actual completed amount and the predicted completed amount, and represents the delay of the actual completion relative to the predicted completion in percentage form. The actual completed amount Sl refers to the amount of work or tasks that have actually been completed at time point t. For example, assume we have a construction project named "XX Building", which is planned to be completed within 24 months. The actual completed amount of the construction progress is extracted from the construction management database every month and compared with the predicted completed amount to evaluate the construction progress status. Assume it is the 4th month of the project now. The following are the actual completed amount data of the "XX Building" project in the past 3 months and presented in percentage:

[0077] Month 1: 5%

[0078] Month 2: 12%

[0079] Month 3: 18%

[0080] These data represent the percentage of the actual completed project volume in the total project volume at the end of each month.

[0081] Step 302: The specific steps for matching the corresponding early warning strategy level based on the current construction progress status are as follows:

[0082] The progress delay threshold set JDy includes a mild delay threshold JDy1, a moderate delay threshold JDy2, and a severe delay threshold JDy3, and JDy1 < JDy2 < JDy3;

[0083] When Jy ≤ JDy, it indicates that the construction progress is within the normal range and no early warning signal is sent outwards;

[0084] When JDy < Jy ≤ JDy1, it indicates that the construction progress is in a mild delay state, and a mild delay early warning signal is sent outwards;

[0085] When JDy2 < Jy ≤ JDy3, it indicates that the construction progress is in a moderate delay state, and a moderate delay early warning signal is sent outwards;

[0086] When Jy > JDy3, it indicates that the construction progress is in a severe delay state, and a severe delay early warning signal is sent outwards.

[0087] According to the matched early warning level, the system automatically generates the corresponding early warning content, including the early warning level, early warning time, early warning reason such as "construction progress lag", influence scope, recommended measures, etc.; according to the preset early warning strategy, select the appropriate early warning method; specifically as follows:

[0088] Mild delay warning: When JDy < Jy ≤ JDy1, the warning signal is sent to the project manager and relevant responsible persons via email or text message, reminding them to pay attention to the progress deviation and suggesting a preliminary analysis to find potential causes;

[0089] Moderate delay warning: When JDy2 < Jy ≤ JDy3, in addition to email and text message notifications, the warning signal is more intuitively displayed in the project management software or BIM model by highlighting the delay area or popping up a window, etc. At the same time, it is recommended that the project team hold a progress coordination meeting to deeply analyze the reasons for the delay and formulate a specific catch-up plan;

[0090] Severe delay warning: When Jy > JDy3, in addition to the above notification methods, more urgent measures can be taken, such as reporting to senior management, activating the emergency response mechanism, increasing resource investment or adjusting project goals, etc.

[0091] It should be noted that the mild delay threshold JDy1, moderate delay threshold JDy2, and severe delay threshold JDy3 need to be set according to the specific situation of the project, historical data, industry standards, and project goals, usually expressed as a percentage or number of days; the progress delay threshold and warning strategy can be dynamically adjusted according to the effect of warning execution and actual situation.

[0092] Combined with the content of steps 301 to 302: By extracting the actual completed quantity and predicted completed quantity from the construction management database every week and calculating the progress delay rate, the real-time monitoring of the construction progress is realized; by setting mild, moderate, and severe delay thresholds, the accurate warning and hierarchical management of the construction progress delay are realized; the warning system automatically generates corresponding warning content according to the preset warning strategy, providing comprehensive and specific decision-making support for project managers; timely warning and effective response measures help reduce the risks brought by project progress delay.

[0093] Step Four: Extract cost data, quality data, and risk data from the construction management database, process and analyze them, and generate the comprehensive delay impact value F d ; According to the comprehensive delay impact value F d Judge the comprehensive impact level;

[0094] The specific steps of Step Four are as follows:

[0095] Step 401: Generate the comprehensive delay impact value F d The specific steps are:

[0096] Obtain cost data, quality data, and risk data from the construction management database, and calculate the cost increase percentage C, quality score Q, and risk deviation degree S;

[0097] The comprehensive delay impact value F is obtained based on the schedule delay rate Jy, cost increase percentage C, quality score Q and risk deviation S. d .

[0098] Step 402: The method for calculating the cost increase percentage C is as follows:

[0099] Cost data at least includes the project budget cost YS and the project actual cost SJ; the cost increase percentage C is calculated based on the project budget cost YS and the project actual cost SJ, and the formula is as follows:

[0100]

[0101] It should be noted that this formula reflects the growth rate of actual cost relative to budget cost. If C is a positive number, it means that the actual cost exceeds the budget cost; if C is a negative number, it means that the actual cost is lower than the budget cost; if C is zero, it means that the actual cost is completely consistent with the budget cost.

[0102] The project budget cost YS is an estimate of the cost required for the project before the project starts, based on factors such as project scope, resource requirements, and time plan. It represents the total cost that the project team plans to invest in order to complete the project under ideal circumstances. The formulation of the budget cost usually involves the collaboration of multiple departments and professionals, including project managers, financial analysts, procurement specialists, etc., to ensure the accuracy and rationality of the budget.

[0103] The actual project cost SJ is the sum of all costs actually incurred during the project execution. It may include labor costs, material costs, equipment rental costs, outsourcing service costs, travel expenses, etc. As the project progresses, the actual cost will continue to accumulate and may deviate from the budgeted cost. These deviations may be caused by a variety of factors, such as resource price fluctuations, demand changes, risk events, etc.

[0104] Step 403: The method for calculating the quality score Q is as follows:

[0105] The quality data includes the actual quality standard score SZ and the perfect quality standard score YZ of the project; the quality score Q is calculated based on the actual quality standard score SZ and the perfect quality standard score YZ, and the formula is as follows:

[0106] Q=YZ-SZ

[0107] Among them, the quality scoring standard is 0-100 points, and the perfect quality standard score YZ is 100 points.

[0108] It should be noted that the perfect quality standard score YZ represents the highest level that this project can achieve in terms of quality;

[0109] The actual quality standard score SZ is the quality score of the project, product or service obtained through actual measurement, evaluation or audit. It reflects the actual quality level currently achieved and may be affected by many factors, such as process level, material quality, management efficiency, etc.

[0110] The quality score Q is based on the actual quality standard score data collected regularly during the project execution process, such as quality control inspections, customer feedback, internal audits, etc., and is compared with the perfect quality standard score to assess the current quality level of the project.

[0111] The specific quality scoring rules are customized by the project review team according to the actual situation and needs of the project. The actual quality standard score of the project should be evaluated based on the specific performance of the project. The specific quality scoring rules should be adjusted and improved according to the actual situation.

[0112] Step 404: The method for calculating the risk deviation S is as follows:

[0113] The risk data includes the minimum risk score ZA and the safety score AQ. The risk deviation S is calculated based on the minimum risk score ZA and the safety score AQ according to the following formula:

[0114] S=ZA-AQ

[0115] Among them, the security risk scoring standard is 0-100 points, 0 represents extremely high risk, and 100 represents the lowest risk;

[0116] When the safety score AQ is close to the minimum risk score ZA, the risk deviation S is close to 0, indicating that the safety risk is low;

[0117] When the safety score AQ is much lower than the minimum risk score ZA, the risk deviation S increases, indicating that the safety risk is high and measures need to be taken to reduce the risk;

[0118] The risk deviation is used to evaluate the changing trend of safety conditions, monitor the risk level, and serve as a basis for formulating safety improvement measures.

[0119] It should be noted that the safety score is a quantitative value of the risk level of the current project, investment or business activity obtained through actual assessment. The safety score is based on a variety of factors, such as market environment, technology maturity, management quality, financial status, etc., and is calculated through a certain scoring system.

[0120] The minimum risk score is a preset quantitative value of the lowest acceptable risk level based on industry standards, historical data or expert judgment. It represents the lowest risk level that a project, investment or business activity can theoretically bear, and a level below which it is generally considered safe or acceptable. The specific value of the minimum risk score should be determined based on actual conditions and used as a benchmark for calculating risk deviation. The minimum risk score and safety score rules should be adjusted and improved based on actual conditions.

[0121] The risk deviation S indicates the degree of deviation of the actual risk level from the minimum acceptable risk level, and this deviation is non-negative. The larger the risk deviation, the higher the actual risk level and the greater the deviation from the minimum acceptable risk level, so the higher the risk of the project.

[0122] The calculation of risk deviation runs through the entire life cycle of the project. In the early stage of the project, the calculation of risk deviation can help decision makers assess the overall risk level of the project, determine whether to continue the project, and whether additional risk management measures are needed; during the project execution, whenever facing major decisions, such as technology selection, partner selection, capital investment, etc., the risk deviation should be recalculated; in addition to calculations at the project start-up stage and key decision points, the risk deviation should also be continuously monitored. This helps to identify potential risk issues in a timely manner and take appropriate countermeasures to ensure that the project can proceed smoothly according to the established goals and plans.

[0123] Step 405: Generate comprehensive delay impact value F d The formula is as follows:

[0124] F d =(Jy×W Jy )+(C×W C )+(Q×W Q )+(S×W S )

[0125] Among them, W Jy is the weight coefficient of the time delay rate, indicating the importance of the time delay on the overall project; W C is the weight coefficient of the cost increase percentage C, which indicates the importance of the cost increase on the overall impact of the project; W Q is the weight coefficient of the quality score Q, indicating the importance of quality degradation on the overall impact of the project; W S is the weight coefficient of the risk deviation S, which indicates the importance of the safety risk to the overall impact of the project; and W Jy +W C +W Q +W S =1;

[0126] It should be noted that this formula uses a weighted summation method to multiply the quantitative values ​​of multiple dimensions, including schedule delay rate Jy, cost increase percentage C, quality score Q, and risk deviation S, by their weights, and add the results to obtain the comprehensive delay impact value F. d .W Jy , W C , W Q and W S The weight value should be determined based on the specific situation of the project, industry standards, and expert opinions;

[0127] In practical applications, the weights of each dimension can be flexibly adjusted according to the specific circumstances and priorities of the project to more accurately reflect the actual impact of project delays.

[0128] Comprehensive delay impact value level threshold set IF d Including low impact level IF d1 , Medium Impact Level IF d2 and high impact level IF d3 , and IF d1 <IF d2 <IF d3 ;

[0129] When IF d1 <F d ≤IF d2 When it is at a low impact level, it means that the construction quality problem has a small impact on the project and can be accepted or easily corrected;

[0130] When IF d2 <F d ≤IF d3 When it is at the medium impact level, it means that the construction quality problem has a certain impact on the project and needs to be closely monitored and corresponding measures taken;

[0131] When F d >IF d3 When it is at a high impact level, it means that the construction quality problem has a significant impact on the project, which may lead to project delays, significant cost increases, or serious safety hazards.

[0132] It should be noted that obtaining the low impact level IF d1 , Medium Impact Level IF d2 The specific method for determining the high impact level threshold is as follows:

[0133] The low impact level threshold is obtained as follows:

[0134] Refer to industry standards or best practices to understand the quantitative indicators of low-impact issues in similar projects. These standards include upper limits on delay time, percentage limits on cost increases, and severity classifications of quality issues.

[0135] Analyze historical data from similar projects within the project organization or industry to identify quantitative indicator ranges that were previously identified as low-impact issues.

[0136] The project management, quality control, risk management and other departments within the organization discuss and jointly determine the threshold of the low impact level based on the actual situation of the project and the risk management strategy. The threshold includes delay time not exceeding X days, cost increase not exceeding Y% of the budget, quality problems not affecting structural safety and easy to repair, etc.

[0137] The impact level threshold is obtained as follows:

[0138] Based on the low impact level threshold, the range of quantitative indicators is further expanded to include the characteristics of medium impact level issues. For example, the delay time may increase to between X and Z days, and the cost increase may reach between Y% and W% of the budget.

[0139] Strengthen the assessment of potential risks and factors that have a certain impact on project progress, cost or quality. Based on the results of risk assessment, determine the risk threshold for medium impact level issues, such as the presence of medium-level personnel safety or environmental risks.

[0140] Combined with the results of quantitative indicator expansion and risk assessment, the threshold of the medium impact level is comprehensively determined. This threshold can accurately reflect the impact of medium impact level issues on the project and provide guidance for subsequent response measures.

[0141] The high impact level threshold is obtained as follows:

[0142] High impact level issues usually involve extreme situations, such as design errors, natural disasters, etc. Therefore, when obtaining high impact level thresholds, the possible consequences of these extreme situations need to be fully considered.

[0143] The triggering conditions of the emergency response mechanism should be included as part of the high impact level threshold. These conditions may include delays far beyond the normal range, uncontrollable cost increases, the risk of serious quality accidents, or the imminent occurrence of high-risk events.

[0144] Due to the severity and complexity of high impact level issues, it is usually necessary to invite experts in related fields to review and make decisions. Experts can provide important references for determining high impact level thresholds based on their professional knowledge and experience.

[0145] It should be noted that the comprehensive delay impact value F dThe specific impacts of the low impact level on the project are:

[0157] Significant cost increase: Additional resources are required, such as overtime and replacement of materials, to solve the problem, causing costs to exceed the budget by a certain percentage;

[0158] Quality defects: quality problems that have a certain impact on structural safety or functionality, such as insufficient strength of the load-bearing structure;

[0159] Medium risk: There are certain risks to personnel safety or the environment, such as insufficient protective measures for working at heights.

[0160] The specific countermeasures are as follows:

[0161] Set up a special team to quickly identify the cause of the problem and develop a solution;

[0163] Conduct comprehensive inspections and repairs on quality defects to ensure compliance with standards;

[0164] Take safety measures immediately, eliminate potential risks, and strengthen safety training.

[0166] Serious delays: Construction activities are delayed for a long time due to major problems, such as design errors and natural disasters, which seriously affect the project schedule;

[0167] Cost out of control: A lot of additional investment, such as redesign and reconstruction, is required to solve the problem, and the cost exceeds the budget significantly;

[0168] Major quality accidents: quality problems that have a serious impact on structural safety or functionality, such as building collapse and structural damage;

[0169] High risk: There are serious risks to personnel safety or the environment, such as fire, explosion and other serious accidents.

[0170] The specific countermeasures are as follows:

[0171] Immediately launch the emergency plan and organize forces to respond with all efforts;

[0172] Communicate urgently with relevant parties, such as owners, designers, and contractors, to jointly develop solutions;

[0173] Suspend construction activities until the problem is fully resolved;

[0174] Strengthen on-site safety management to ensure personnel safety and prevent accidents from expanding;

[0175] Conduct an in-depth investigation into the accident, summarize experience and lessons, and improve relevant systems and processes.

[0176] Combined with the contents of step 401 to step 405: by comprehensively considering multiple dimensions such as schedule delay, cost increase, quality degradation and safety risk, a comprehensive delay impact value is generated, providing a comprehensive and objective project status assessment tool for project managers; by quantifying the schedule delay rate, cost increase percentage, quality score and safety score, and assigning them different weights, the decision-making process is made more scientific; according to the different levels of the comprehensive delay impact value, the corresponding early warning mechanism is automatically triggered to remind project managers to pay attention to potential risks and take corresponding measures; through a comprehensive assessment of the project status, it helps project managers to allocate resources more reasonably; by regularly publishing the comprehensive delay impact value and its assessment results, the transparency and credibility of the project are enhanced, providing strong support for the continuous optimization and improvement of the project.

[0180] Step 502: Combine the construction progress optimization suggestion report and the comprehensive impact level assessment report to identify which parts or links are delayed and analyze the reasons for the delays; according to the comprehensive impact level, assess the impact of delays, cost increases, quality declines or risk increases on the overall project goals; use the spatial analysis function of the BIM model, combined with the construction progress and comprehensive impact data, to accurately locate the specific parts and factors that cause the problem;

[0181] Step 503: Based on the identified problems, a targeted optimization strategy is formulated in combination with the 3D visualization function of the BIM model, for example:

[0182] Use the construction simulation function of the BIM model to re-plan the construction sequence and reduce idle time and waiting time;

[0183] According to the construction progress requirements, rationally allocate human, material, financial and other resources to ensure the supply of resources on the critical path;

[0188] Step 504: Present the optimization strategy in the form of a report, including problem description, cause analysis, optimization plan, expected effect, etc., and provide a 3D visualization of the BIM model so that the project team can intuitively understand and discuss the implementation.

[0189] Combined with the contents of steps 501 to 504: BIM's 3D visualization makes the problem clear at a glance, promoting rapid understanding and communication among the team; integrating multi-source data to accurately find the root cause of the problem; formulating scientific and reasonable optimization strategies based on the root cause of the problem; providing managers with comprehensive and in-depth information support to improve decision-making efficiency; promoting cooperation and knowledge sharing among team members; quickly solving problems, reducing trial and error and waste, and improving project management efficiency; improving project transparency so that relevant parties can keep abreast of project progress and problems.
