[0001] The present invention relates to the technical field of BIM, and in particular to a dynamic construction management method based on BIM technology. Background Art

[0002] The construction industry is an important pillar of the national economy, but there are often many problems in traditional construction management. For example, there is a lack of effective information sharing mechanism between various departments on the construction site, which leads to untimely information transmission, thus affecting construction efficiency; the construction site management department is unable to grasp the actual situation of the construction site in real time, resulting in delayed construction decisions, which in turn affects the construction progress and quality; due to information opacity, resource allocation is unreasonable during the construction process, leading to project delays, cost overruns and safety accidents.

[0003] The emergence of BIM technology has made it possible to solve the limitations of traditional construction management. With its powerful information integration, visualization, simulation and analysis capabilities, BIM technology has provided strong support for the informatization of the construction industry.

[0004] At present, many projects only use BIM for static display, fail to effectively combine real-time data, lack of systematic dynamic management solutions, and thus cannot timely reflect the complex and changing environment of the construction site, increasing management risks. Therefore, a dynamic construction management method based on BIM technology is extremely important.

[0061] Example 1, please refer to Figure 1 and Figure 5 , a dynamic construction management method based on BIM technology, comprising the following steps:

[0062] S1. Construction of information sharing platform: Based on the needs of the construction site and construction operations, cloud computing technology is used to build a platform for multi-user real-time access, update and storage data. A security system is built for the information sharing platform, and a permission management mechanism is set up. The information sharing platform provides different access channels for construction personnel according to their positions at the construction site, grants construction personnel different data access rights and modification rights, and uses a multiple authentication mechanism to verify user identity. The information sharing platform records users' data access and operation behaviors in real time, including access time, access users and modification record inspection and tracking;

[0063] S2. Real-time data sharing: Use sensor networks, drones and inspection robots to collect data from the construction site in real time, including construction progress, material usage and equipment status. Through the designed standardized data interface, the collected data from the construction site is transmitted to the information sharing platform in real time. The information sharing platform standardizes the data and adds an accurate timestamp to the data. The processed data is shared with the software and equipment of different departments at the construction site through the standardized data interface.

[0064] S3. Update and display of BIM model: Use BIM software to build a three-dimensional model of the building according to construction requirements, upload the BIM model to the information sharing platform, and the information sharing platform will synchronize the data of the construction site to the BIM model in real time. According to the real-time synchronized data, the BIM model will be dynamically updated, and the dynamic BIM model will be displayed to various departments on the construction site in real time through the visual interface of the information sharing platform;

[0065] S4. Analysis and discussion of construction work: The information sharing platform conducts intelligent analysis of the data synchronized to the BIM model, conducts risk analysis of construction work, makes and adjusts construction decisions, automatically adjusts construction plans and resource allocation, and introduces instant messaging, video conferencing and shared document communication tools on the information sharing platform. The information sharing platform formulates a meeting schedule, regularly holds online discussion meetings between departments and construction personnel, and evaluates project progress;

[0066] Furthermore, an information sharing platform is established to enable departments of construction projects to obtain the latest data and progress of the construction site at any time. The information sharing platform integrates the data of various equipment on the construction site through standardized data interfaces, and shares the data with various departments on the construction site in real time, so that each department can obtain the required information in a timely manner, reducing delays and misunderstandings in information transmission and breaking down information barriers between departments. The information sharing platform accurately timestamps the data, realizes time synchronization processing of the data, and ensures the real-time nature of the shared data;

[0067] By setting up a permission management mechanism, the information sharing platform ensures that sensitive data on the construction site can only be accessed and modified by authorized personnel, avoiding data leakage and abuse. The use of a multi-authentication mechanism further improves the security of the platform. The information sharing platform records users' data access and operation behaviors, helping construction project managers to promptly discover and respond to potential safety hazards.

[0068] The information sharing platform feeds back real-time data from the construction site to the BIM model, so that the BIM model is always synchronized with the actual situation on the construction site, thereby improving the accuracy of the BIM model. The visual interface of the information sharing platform intuitively displays the specific information of the BIM model, so that construction personnel can obtain the latest data from the construction site in real time, such as construction progress, quality status, safety hazards, etc., so that construction managers can make more timely and accurate decisions. Based on the real-time updated BIM model, different construction teams can clearly understand their respective work content and the connections between the teams, and evaluate the progress of the project through regular online discussion meetings, thereby achieving more efficient collaborative work.

[0069] Example 2, please refer to Figure 1 and Figure 5 , a dynamic construction management method based on BIM technology, comprising the following steps:

[0070] Step 1: Use cloud computing technology to build an integrated cloud platform and design the overall architecture of the cloud platform, including network architecture, data architecture, storage architecture, and computing resource allocation. The cloud platform is used for real-time access and update of storage data by multiple users, and the platform is divided into multiple functional modules;

[0071] Step 2: According to the needs of construction work, design a data identification mechanism to identify the importance and sensitivity of data, use encryption algorithms to encrypt sensitive data and important data in the information sharing platform, and enable authorized users to access encrypted data through the set permission management mechanism;

[0072] Step 3: The information sharing platform formulates a data backup strategy based on the needs and progress of the construction work, automatically and regularly backs up the encrypted data, and standardizes the time for backing up data. It also sets a plan for automatically verifying the backup data, verifying the integrity and timeliness of the data, and formulating a plan for regularly cleaning up expired data based on the timeliness of the data.

[0073] Step 4: Deploy a network monitoring system to continuously monitor the network status and data transmission of the information sharing platform. When the network status is abnormal or the data is wrong, quickly locate the fault location and notify the management staff to take recovery measures in time.

[0074] Furthermore, the information sharing platform collects data from various equipment on the construction site through standardized data interfaces. The information sharing platform identifies data involving commercial privacy as sensitive data and data that affects the construction progress as important data. The identified sensitive data and important data are encrypted to prevent unauthorized access and tampering, thereby ensuring the security of data during transmission and storage.

[0075] According to the needs of construction work and the actual progress of construction, the information sharing platform formulates a data backup strategy and regularly backs up data to ensure that the data, construction progress, quality control and other information in the BIM model are fully preserved. When construction personnel view historical BIM model data, it is to avoid that the management personnel cannot understand the construction progress due to data loss. The backup data is checked regularly or as needed to ensure the validity and reliability of the backup data, thereby ensuring the accuracy of the BIM model data, cleaning up data that has not been used for a long time or has lost its value, and avoiding useless data from occupying the storage resources of the information sharing platform;

[0076] The network status and data transmission of the information sharing platform are continuously monitored through the network monitoring system, thereby ensuring the stability of the network signal quality, and then ensuring the real-time data transmission, solving the problem of data transmission delay caused by unstable signal quality, thereby further improving construction management efficiency. When data errors occur, managers can locate the fault location and take timely action, thereby improving the accuracy of the BIM model and avoiding data errors from affecting the construction progress.

[0077] Example 3, please refer to Figure 1 , Figure 2 and Figure 7 , a dynamic construction management method based on BIM technology, comprising the following steps:

[0078] Step 1: According to the needs of the construction site and construction operations, use cloud computing technology to build a platform for multi-user real-time access, update and storage data, build a security system for the information sharing platform, set up a permission management mechanism, use sensor networks, drones and inspection robots to collect data from the construction site in real time, including construction progress, material usage and equipment status, and transmit the collected data from the construction site to the information sharing platform in real time through the designed standardized data interface. The information sharing platform standardizes the data and adds an accurate timestamp to the data. The processed data is shared with the software and equipment of different departments at the construction site through the standardized data interface. Use BIM software to build a three-dimensional model of the building according to construction requirements, upload the BIM model to the information sharing platform, and the information sharing platform synchronizes the data from the construction site to the BIM model in real time. According to the real-time synchronized data, the BIM model is dynamically updated, and the dynamic BIM model is displayed to various departments at the construction site in real time through the visual interface of the information sharing platform. The information sharing platform performs intelligent analysis on the data synchronized to the BIM model and conducts risk analysis of construction operations;

[0079] Step 2: The information sharing platform formulates an inspection plan based on the construction environment data and construction needs. The platform shares the inspection plan with drones and inspection robots in real time. The inspection plan includes: regular inspection of the behavior of construction site personnel, equipment operation status, construction progress and material inventory;

[0080] Step 3: The information sharing platform collects inspection data and construction material transportation data in real time. The platform synchronizes environmental data, transportation data and inspection data to the BIM model in real time. The platform simulates and analyzes the data in the BIM model to assess the risks of construction material transportation. The information sharing platform analyzes the probability of construction vehicles encountering congestion based on the location information and road information of the construction vehicles, and determines the impact of traffic congestion, bad weather and road damage on construction vehicles. The information sharing platform evaluates the risk of construction vehicles arriving at the construction site late by analyzing data, simulates the time point of delayed arrival of construction vehicles, and identifies potential risks in the construction process, including: insufficient inventory of construction materials and the inability to transport materials to the construction site in time, construction personnel in dangerous environments and engaging in dangerous behaviors, and the construction site is in bad weather;

[0081] Step 4: The information sharing platform conducts quantitative assessment of the identified risks, prioritizes the risks according to their severity and probability of occurrence, formulates emergency plans to prioritize high-priority risks, formulates and adjusts construction decisions, and automatically adjusts construction plans and resource allocation. By introducing instant messaging, video conferencing, and shared document communication tools on the information sharing platform, the information sharing platform formulates a meeting schedule, regularly holds online discussion meetings between departments and construction personnel, and evaluates project progress;

[0082] Furthermore, the information sharing platform synchronizes environmental data, transportation data and inspection data to the BIM model in real time, and simulates and analyzes the data in the BIM model to predict the consumption and delivery of construction materials. When the inventory of construction materials is insufficient and the construction materials cannot be delivered to the construction site in time, or the construction workers are in a dangerous environment and engage in dangerous behavior, or the construction site is in bad weather, the information sharing platform will evaluate the impact and probability of the risk based on the risk prediction information, and formulate emergency plans that give priority to those with the greatest impact on the construction progress and the highest probability of risk occurrence. The information sharing platform will transmit the emergency plans to the corresponding departments in real time;

[0083] The information sharing platform will adjust the construction plan according to the scope and degree of risk impact, so as to prevent construction hazards from affecting the construction progress and avoid the suspension of construction projects. At the same time, the information sharing platform will formulate meeting plans to discuss issues related to construction site risks to avoid the occurrence of risks or hidden dangers, ensure the safety of construction personnel, improve construction management efficiency, ensure the uninterrupted progress of construction projects, and ensure that enterprises can complete construction work on schedule.

[0084] Example 4, please refer to Figure 1 and Figure 4 , a dynamic construction management method based on BIM technology, comprising the following steps:

[0085] Step 1: The information sharing platform conducts intelligent analysis of the data synchronized to the BIM model, conducts risk analysis of construction operations, formulates and adjusts construction decisions, and automatically adjusts construction plans and resource allocation. By introducing instant messaging, video conferencing, and shared document communication tools on the information sharing platform, the information sharing platform plans meeting contents of different topics based on construction needs, construction progress, and construction risk information. According to the importance and urgency of the meeting content and the time schedule of the construction project, a meeting schedule is formulated;

[0086] Step 2: Use the communication tools in the information sharing platform to send meeting notices to construction teams in different departments, including meeting agendas and meeting materials. The information sharing platform uses facial recognition technology to identify the identities of participants and determine their information;

[0087] Step 3: The information sharing platform records the meeting content in real time and promptly feeds back the meeting content to the management department. The information sharing platform regularly collects feedback from participants and replans the meeting schedule based on the feedback;

[0088] Furthermore, the information sharing platform integrates a variety of communication tools, breaks down the barriers between different departments of the construction project, promotes information sharing and collaboration among construction teams, and improves overall work efficiency. The information sharing platform conducts intelligent analysis of the data in the BIM model, identifies potential risk points and efficiency bottlenecks in the construction process, and automatically generates meeting content on different topics based on construction needs, progress and risk information to ensure the pertinence and effectiveness of the meeting. Combined with the construction project schedule, a meeting schedule is formulated to reasonably arrange meeting time and thus improve meeting efficiency.

[0089] Through the communication tools within the information sharing platform, the platform sends meeting notices to construction teams in different departments, including meeting agendas and meeting materials, so that participants can prepare in advance. Facial recognition technology is used to identify the identities of participants to ensure the safety and order of the meeting. The recorded meeting content helps management quickly obtain information, thereby making more scientific and reasonable construction decisions, preparing for subsequent construction work, and improving the efficiency and quality of construction work. The platform optimizes the meeting process and content based on the feedback from the meeting, thereby improving the actual effect of the meeting, ensuring effective feedback on construction site problems, and ensuring the rapid resolution of construction problems. The real-time recording and feedback mechanism of construction meeting content helps to improve the transparency of construction management and ensure that decisions are effectively implemented.

[0090] Example 5, please refer to Figure 3 and Figure 8 , a dynamic construction management method based on BIM technology, comprising the following steps:

[0091] Step 1: Based on the construction requirements and the analysis of the data in the BIM model, the information sharing platform initially formulates a construction plan, adjusts the personnel allocation of various departments on the construction site, plans the execution sequence of the construction projects, allocates construction equipment and materials for different construction projects, and designs a variety of different construction plans;

[0092] Step 2: The information sharing platform uses simulation and prediction technology to evaluate the impact of different construction plans on construction progress and construction costs. Based on the evaluation results of the construction plan, the information sharing platform selects the optimal construction plan. The information sharing platform synchronizes the construction plan to various departments on the construction site in real time and notifies the construction personnel to implement the construction plan as planned;

[0093] Step 3: The information sharing platform determines the actual construction progress of the construction site by analyzing the detection data and inspection data of the sensor network, and compares the actual progress data with the planned progress by predicting and analyzing the construction plan. When the planned progress of the construction differs greatly from the actual progress, the information sharing platform analyzes the lag and advance of the construction link, and determines the actual factors affecting the difference in construction progress by combining the risk information of the construction operation;

[0094] Step 4: The information sharing platform adjusts and optimizes the construction plans under different circumstances based on the analysis results. When the construction progress is affected by bad weather, the human resources, equipment resources and network resources of the construction project are reallocated according to the scope of impact.

[0095] Step 5: In the case of insufficient inventory and excessive accumulation of construction materials, the information sharing platform adjusts the construction plan, giving priority to construction projects with accumulated materials and reducing resource allocation for construction projects with insufficient inventory of construction materials;

[0096] Furthermore, the information sharing platform initially formulates a variety of different construction plans based on the construction requirements and real-time data in the BIM model. By analyzing the allocation of construction site personnel, the execution sequence of construction projects, and the allocation of construction equipment and materials, the platform predicts the impact of different plans on construction progress, construction cost, construction quality, etc. Based on the evaluation results, the platform selects the best construction plan and accurately formulates the construction plan, thereby improving construction efficiency and avoiding problems such as low construction quality and construction delays caused by poor construction plans.

[0097] The information sharing platform compares the actual progress of the construction with the planned progress, determines the lag or advance of the construction link, and combines the risk assessment information to determine the actual factors affecting the difference in construction progress, and then adjusts the construction plan and reallocates the human resources, equipment resources and network resources of the construction project to ensure that the construction work can be completed on schedule. In the case of insufficient inventory of construction materials or excessive accumulation of materials, the resource allocation of the construction project is adjusted to solve the problem of excess or insufficient inventory, avoid waste and idle resources, and effectively reduce construction risks.

[0098] Example 6, please refer to Figure 2 and Figure 6 , a dynamic construction management method based on BIM technology, comprising the following steps:

[0099] Step 1: The information sharing platform formulates an inspection plan based on the construction environment data and construction needs. The information sharing platform sets the inspection range and inspection route of the drone based on the environmental data of the construction site. The information sharing platform identifies the location information of construction equipment and construction personnel based on the inspection data shared by the drone. The information sharing platform analyzes the mobilization of construction equipment and construction personnel through the location information and generates the inspection strategy of the inspection robot. The inspection robot executes the inspection plan according to the inspection strategy and detects the construction progress and equipment status information of the construction equipment.

[0100] Step 2: The information sharing platform collects inspection data and construction material transportation data in real time. The platform synchronizes environmental data, transportation data and inspection data to the BIM model in real time. The platform simulates and analyzes the data in the BIM model, evaluates the risks of construction material transportation, and identifies potential risks in the construction process, including: insufficient inventory of construction materials and failure to transport materials to the construction site in time, construction workers in dangerous environments and engaging in dangerous behaviors, and the construction site is in bad weather;

[0101] Step 3: The information sharing platform conducts quantitative assessment of the identified risks, prioritizes the risks according to their severity and probability of occurrence, and formulates emergency plans that prioritize high-priority risks;

[0102] Furthermore, the information sharing platform sets the inspection plan of the drone based on the construction environment data and construction requirements, ensuring that the drone can prepare and completely collect the real-time data of the construction site to avoid the problem of blind inspection areas. The information sharing platform synchronizes the inspection data to the BIM model in real time to ensure that the model can accurately reflect the location information of each equipment and personnel change information on the construction site;
