Description

This invention relates to a process management support system, a process management support method, and a program for understanding and managing the progress of construction work at a construction site. In construction sites, the progress of construction is often managed by compiling records from construction managers and reports from specialized contractors, which is a cumbersome process and presents challenges in information sharing. In this context, for example, Patent Document 1 discloses a building construction management system that supports building construction management. In the construction management system described in Patent Document 1, information such as the name, location, and shape of each component constituting the building is imported and set from, for example, BIM (Building Information Modeling) software that allows for the three-dimensional design of the building in a virtual space. Furthermore, information such as the construction cost, planned start date, planned completion date, actual start date, and actual completion date for each component constituting the building is imported and set from software that supports the construction process management of the building. This allows for the three-dimensional, visual display of components that have been completed, are progressing smoothly, are ahead of schedule, and are behind schedule, based on a predetermined reference date, using BIM software. Patent No. 6876523 This figure shows the BIM model and element model in an embodiment of the present invention.This figure shows the surveying means in an embodiment of the present invention.This figure shows a schematic of the three-dimensional point cloud data in an embodiment of the present invention.This figure shows a bounding box and a determination frame in an embodiment of the present invention.This diagram shows the flow of a process control support method according to an embodiment of the present invention.This figure shows a process control support system according to an embodiment of the present invention.This figure shows the element model of the construction section set as the target for construction determination in an embodiment of the present invention.This figure shows an example of displaying the construction determination result in a BIM model according to an embodiment of the present invention.This diagram shows the stages of distribution of construction materials in the construction of a structure. <<<<Distribution of construction materials>>>> Construction components E used in the construction of building B are manufactured at factory f1, as shown in Figure 9, and stored in the storage area of factory f1. Then, the construction components E are loaded onto a freight car v1 and transported from factory f1 to the construction site f2. After the construction components E are brought to the construction site f2, they are temporarily stored in the stockyard of the construction site f2. Next, the construction components E stored in the stockyard are transported to the work yard where construction will take place. If necessary, multiple construction components E are assembled in the work yard. Then, using a tower crane or similar equipment, they are lifted from the work yard and the construction components E are installed (erected). Afterward, the construction components M used in the erection of building B are inspected. <<<Process Management Support System and Process Management Support Method>>> The process management support system and process management support method automatically determine whether the erection of construction components E at the distribution stage, as described above, is completed or incomplete, and supports the process management of construction work. The details of the process management support system and process management support method will be explained below with reference to Figures 1 to 8. The automatic determination of whether construction is complete or incomplete utilizes a 3D geometric model of the structure, which is constructed on a computer before construction, and 3D point cloud data generated by surveying the structure during construction. While there are no limitations on the method of constructing the 3D geometric model, this embodiment uses a Building Information Modeling (BIM) model as an example. First, we will explain the BIM model 10, element model 11, 3D point cloud data D, bounding box 40, and judgment frame 41 used in the process control support system and process control support method. <<<BIM Model / Element Model>>> As shown in Figure 1, the BIM model 10 is a three-dimensional model of the actual building B constructed on a computer using BIM software. The three-dimensional geometric element models 11, which are components of the BIM model 10, are three-dimensional models of the actual construction members E that make up building B. The element models 11 are assigned attribute information, placement information, and shape info
