Description

This disclosure relates to a construction management system, construction management methods, and construction management programs. To improve construction efficiency and quality control, efforts are underway to recreate construction sites in virtual spaces, such as digital twins, for simulations and other purposes. Three-dimensional information of geographical features is used as point cloud data to recreate construction sites. Point cloud data is generated, for example, using measurement methods with laser scanners or photogrammetry methods with UAVs (Unmanned Aerial Vehicles). In civil engineering projects, verification is performed to ensure that the work within the construction area is proceeding according to the plan. However, reflecting real-world progress in the construction area within the virtual space required operators to manually modify the ground surface based on point cloud data, which was time-consuming. For example, Patent Document 1 describes generating a wireframe model of terrain, assigning surfaces to the wireframe to generate a surface model, and simultaneously generating a voxel model that approximates the surface model. In this system, the measured stake positions are displayed in a virtual space containing a collection of voxels, visualizing the discrepancy between the voxels and the stake positions.

The construction management system 1 comprises one or more information processing devices. In the example shown in Figure 1, the construction management system 1 comprises a construction management device 10. The construction management device 10 is a terminal used by users such as construction managers. The construction management device 10 is connected to a server 11 via a network (not shown). The construction management device 10 comprises a control unit 12, a ground surface data storage unit 13, an object storage unit 14, an attribute data storage unit 15, and a construction plan storage unit 16. The control unit 12 functions as a construction management unit 17, an attribute information generation unit 18, and an image processing unit 19 by executing a program. The Construction Management Department 17 identifies the construction unit quantity for the construction scope of civil engineering work in the virtual space, according to the construction divisions. Construction divisions are either spatial or temporal divisions. The construction unit quantity indicates the amount of work divided by these divisions. An example of a spatial construction division is the location of temporary structures such as shoring. Another example of a spatial construction division is a division based on the working capacity of construction machinery. This division might be, for example, the capacity of a backhoe bucket. A temporal division is the planned amount of work to be done within a predetermined period (e.g., one day). The construction management unit 17 determines the size of the voxels, which are elements that divide the construction area, according to the construction unit quantity. The construction management unit 17 acquires the data necessary for construction management from the server 11. Furthermore, the construction management unit 17 acquires the data necessary for construction management from each storage unit 13-16 and updates the data in each storage unit 13-16 as needed. Furthermore, the construction management unit 17 acquires construction performance data from the construction machinery 100 via the server 11. The construction management unit 17 may also directly receive construction performance data from the construction machinery 100. Alternatively, the construction management unit 17 may acquire data entered by the user via the input device H14 (see Figure 3). The attribute information generation unit 18 associates attribute data with each voxel an
