[0076] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0077] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0078] Example 1, with reference to Figure 1 and Figure 2 , which is the first embodiment of the present invention, provides a municipal road construction method based on BIM, comprising the following steps:

[0079] S1. Use data collection and preprocessing methods to collect geographic information and clean data on the construction site to obtain a standardized basic data set;

[0080] Furthermore, the LiDAR system carried by the drone is used to conduct a comprehensive scan of the construction site to obtain detailed geographic information including terrain height and surface roughness;

[0081] A statistical method was used to remove outliers in the collected data, and bilinear interpolation was used to fill data gaps and obtain a standardized basic data set;

[0082] It should be noted that the use of UAV-mounted LiDAR systems for geographic information collection not only improves the speed and accuracy of data acquisition, but also enables coverage of complex terrain areas that are difficult to reach with traditional methods. Statistical methods are used to remove outliers and bilinear interpolation is used to fill data gaps, ensuring the integrity and consistency of the data set and providing a solid foundation for subsequent three-dimensional modeling.

[0083] S2, using a 3D modeling method to construct a 3D model of the standardized basic data set to obtain a 3D road model;

[0084] Furthermore, based on the obtained standardized basic data set, the digital elevation model (DEM) algorithm is applied to generate the terrain surface, which is expressed as:

[0085] Z(x,y)=D clean (x,y)+α·sin(βx+γy);

[0086] Where Z(x,y) represents the terrain height at position (x,y), α is the adjustment coefficient used to control the degree of fluctuation of the terrain surface, β is the horizontal frequency factor, and γ is the vertical frequency factor used to adjust the rate of change of the terrain surface waveform.

[0087] Based on the terrain model, road structure elements were added using BIM software Revit according to design specifications and requirements;

[0088] Road structural elements include pavement, curbs, and drainage systems;

[0089] For each structural element, define its geometric parameters, which are expressed as:

[0090] V elem=L×W×T;

[0091] Among them, V elem is the volume of the structural element, L is the length, W is the width, and T is the thickness;

[0092] Integrate all independent structural element models with the terrain model to form a complete three-dimensional road model;

[0093] It should be noted that the application of the digital elevation model (DEM) algorithm to generate the terrain surface, combined with the adjustment coefficient, horizontal frequency factor and vertical frequency factor, can flexibly adjust the details and fluctuation of the terrain surface, so that the generated terrain model is more in line with the actual situation. By adding road structural elements on the basis of the terrain model and defining the specific geometric parameters of each structural element, accurate simulation of road design is achieved, which helps to discover potential design problems in advance and optimize the design plan.

[0094] S3, using 4D schedule planning and simulation methods to integrate the time dimension of the road 3D model to obtain a 4D model;

[0095] Furthermore, according to the project plan and actual needs, the time parameters of each construction phase are defined as follows:

[0096] T i =t i+1 -t i ;

[0097] Among them, T i represents the duration of the i-th construction phase, t i is the start time of this stage, t i+1 The end time of this stage;

[0098] Assign specific construction tasks to the corresponding time periods and plan the required resources. For each construction task, calculate the required resources. The expression is:

[0099] R j =k j ×V j ;

[0100] Among them, R j is the amount of resources required for task j, k j is the amount of resources required per unit volume for a specific task, V j is the volume of the structural element involved in task j;

[0101] Using Navisworks software tools, the time dimension T i Integrate into the 3D road model to form a 4D model;

[0102] It should be noted that by integrating the time dimension into the three-dimensional model to form a 4D model, project managers can dynamically observe changes in construction progress in a virtual environment and identify potential time conflicts and resource bottlenecks. Dynamic simulation not only helps to formulate more reasonable construction plans, but also foresee possible problems in advance, so as to take corresponding preventive measures and reduce the risks of construction delays and cost overruns.

[0103] S4. Use multi-disciplinary coordination and conflict detection methods to conduct cross-disciplinary collaboration and conflict detection on the 4D model to obtain a conflict-free construction plan;

[0104] Furthermore, a centralized BIM platform was created to enable teams from different disciplines, including structural engineering, plumbing systems, and electrical engineering, to access and update project information in real time.

[0105] Synchronize design data to the BIM platform and integrate it through unified data standards;

[0106] Calculate the distance difference between each professional element in the design data to ensure data consistency. The expression is:

[0107]

[0108] Where Δd ij represents the distance between the i-th professional element and the j-th professional element, x i ,y i , z i are the coordinates of the i-th element in three-dimensional space, x j ,y i , z j are the coordinates of the j-th element in three-dimensional space;

[0109] Utilize the built-in conflict detection tool of BIM software to automatically scan the entire 4D model and identify potential spatial conflicts between different disciplines;

[0110] For each detected conflict point, record its location information and the professional elements involved;

[0111] Organize a cross-disciplinary team to discuss and develop solutions for each conflict point;

[0112] When water supply and drainage pipes are found to intersect with electrical lines, the conflict is avoided by adjusting the installation path of one of the systems;

[0113] It should be noted that creating a centralized BIM platform enables teams from different disciplines to access and update project information in real time, greatly improving the efficiency of cross-disciplinary collaboration. It automatically calculates the distance difference between professional elements and uses built-in conflict detection tools to scan the entire 4D model, which can quickly identify and resolve potential spatial conflicts, avoiding on-site rework and delays caused by design conflicts, and significantly improving the smoothness and safety of the construction process.

[0114] S5. Use real-time monitoring and feedback adjustment methods to implement and monitor conflict-free construction plans on-site in real time to achieve high-quality construction results;

[0115] Going a step further, sensors are installed at key points of the structure and near underground pipelines at the construction site;

[0116] The sensors include temperature sensors, humidity sensors and displacement sensors;

[0117] Use IoT technology to establish data transmission channels;

[0118] In the central control system, the received data is analyzed in real time to assess whether the current construction status meets expectations;

[0119] When any deviation from the planned construction plan is discovered, the feedback mechanism is activated and corresponding adjustment strategies are formulated according to the degree of deviation;

[0120] Conduct a comprehensive inspection of construction quality and progress, and compare the actual completion status with the planned targets;

[0121] When quality problems or progress delays are discovered, corrective measures are taken promptly;

[0122] By increasing resources R add To speed up the progress, the expression is:

[0123] R add =k×(T expected -T actual );

[0124] Among them, R add is the additional resource amount, k is the resource coefficient, T expected is the expected completion time, T actual is the actual completion time;

[0125] It should be noted that by installing sensors at the construction site and establishing a data transmission channel through the Internet of Things technology, real-time monitoring of the construction status is achieved. The received data is analyzed through the central control system to promptly detect any deviation from the predetermined construction plan, and the feedback mechanism is activated to formulate corresponding adjustment strategies to ensure that the construction quality and progress are always under control. This method not only improves construction efficiency, but also reduces delays in construction due to unforeseen problems.

[0126] S6. Use the completion acceptance and maintenance plan method to conduct final inspection and archive the high-quality construction results to obtain complete project records and subsequent maintenance plans;

[0127] Furthermore, after all construction activities are completed, an acceptance team consisting of the owner, designer and supervision engineer will be organized to conduct a comprehensive quality inspection of the entire project;

[0128] When any defects or non-conformity with design standards are found during the quality inspection process, they will be recorded immediately and detailed corrective measures will be formulated;

[0129] Systematize all relevant documents throughout the project cycle and archive them in a unified standard format;
