BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 3 is a functional block diagram showing a functional configuration of the construction work management device according to the embodiment. In this figure, a PC-CAD (Personal Computer-Computer Aided Design) 1 includes a plot plan storage unit 2 in which two-dimensional CAD data such as a construction site is stored, a PDS (Plant Design System) model data storage unit 3 Then, data is read from the device, a predetermined process is performed on the read data to form three-dimensional model data, and the data is written to the project database 11. In addition, data is read from the equipment figure 4 showing the shape of the target equipment to be carried in and installed in the construction, the scaffold / temporary object design drawing 5, and the construction machine specification 6, and a 3D simulation is performed based on these data. 3D model data to be created is written to the project database 11 and the construction machine database 12. As a result, the three-dimensional model data of the shape of the target equipment to be carried in and installed and the three-dimensional model data of the construction site such as the shape of the existing facility and the frame are written in the project database 11 and the construction machine such as a crane Is written into the construction machine database 12.
[0015]
Reference numeral 8 denotes a schedule database in which the schedule of the construction work created by this is stored as text data.
Reference numeral 10 denotes a construction management unit, which includes the above-mentioned databases 11, 12, a program storage unit 14, an animation recording file 15, a CPU (Central Processing Unit; not shown) that performs processing according to a program in the program storage unit, and an input. And a display device (both not shown). In this case, the program storage unit 14 stores a program for connecting the schedule database 8 with the three-dimensional model data in the project database 11 and the construction machine database 12, and stores the program in FWBS (Functional Work Breakdown Structure: work classification by function). And a program that classifies using the definition.
[0016]
Next, the operation of the construction work management device described above will be described with reference to the flowcharts shown in FIGS.
(1) Creation of Management Database The management database is a database for schedule management, and is created as a part of the project database 11. The project database 11 includes a database of three-dimensional model data in addition to the management database.
FIG. 4 is a flowchart showing the process of creating the management database. First, it is determined whether schedule data has already been input to the schedule database 8 (step Sa1). If the schedule data has not been input, the schedule data is directly input from the keyboard (step Sa2). The input data is written to the project database 11. If the schedule data has already been input to the schedule database 8, the schedule data is loaded into the project database 11 (step Sa3).
[0017]
Next, it is checked whether three-dimensional model data is prepared in the PDS model data storage unit 3 (step Sa4). If the model data has been prepared, the model data is processed (step Sa5), and the three-dimensional model data is loaded into the project database 11 (step Sa6). If the model data has not been prepared, the scaffold / temporary object design drawing 5, the construction machine specification 6 and the equipment drawing 4 are acquired (step Sa7), and 3 based on the acquired design drawing and specification. The dimensional model data is created (step Sa8), and the created model data is loaded into the project database 11 (step Sa6).
[0018]
Next, each schedule item of the schedule data in the project database 11 is combined with the model data. This is done by having information for assigning a rule for each FWBS and designating the rule for each schedule item.
[0019]
(2) Construction Work Simulation FIG. 5 is a flowchart showing a process of the construction work simulation. When the user inputs a date for performing the simulation, the site situation for that date is called from the project database 11 and displayed (step Sb1). Next, the user selects a target device to be loaded and installed, and sets the weight, the position of the center of gravity, and the position of Liftng Lug (projection for lift) (step Sb2). Next, the target device is placed in the site situation (step Sb3). Next, a work radius is input, and a construction machine is selected from the construction machine database 12 (step Sb4). If the selected construction machine has not been set in the database 12 (step Sb5), three-dimensional model data is created (step Sb6) and registered in the construction machine database 12 (step Sb7).
[0020]
If the construction machine selected in step Sb4 is set in the database 12, the model data of the construction machine is read from the database 12, and a simulation is performed based on the model data and the model data indicating the site situation. Done. In this simulation, the work radius input in step Sb4 is confirmed, and an overload (overload) is confirmed. If there is a problem as a result of the simulation, the construction machine is selected again, and then the simulation is performed again. If there is no problem as a result of the simulation, the process of the simulation is recorded in the animation recording file (step Sb9). Next, the created animation file is stored in the project database 11 (step Sb10).
[0021]
(3) Schedule Simulation FIG. 6 is a flowchart showing the process of the schedule simulation. First, the user inputs a start date and an end date of the schedule simulation on the display screen (step Sc1). Next, the user specifies how many days should be displayed (step Sc2). When this designation is made, a still image simulation is performed. That is, the schedule between the start date and the end date and the three-dimensional model data of the construction site corresponding to each schedule item are read from the project database 11 and sequentially displayed as characters and still images (step Sc3). Here, if there is a problem with the displayed schedule, the user adjusts the schedule (step Sc4). Then, the process of steps Sc1 to Sc3 is repeated again to perform a simulation. In this case, various cases can be simulated by changing the state of the connection between the schedule item and the construction site and the information on the schedule.
[0022]
If there is no problem in the schedule, the process may be terminated as it is, or a moving image simulation may be performed. In the case of performing a moving image simulation, when a user performs a key operation for instructing a moving image simulation using a keyboard and a mouse, animations recorded in the construction work simulation are arranged on a schedule and displayed in chronological order (step Sc5). ). Next, the user connects the animation file and the schedule item (step Sc6). Next, the user specifies a period (up to two weeks) for displaying the animation.
[0023]
When the above specification is performed by the user, the site situation of the specified end date is read from the project database 11 and displayed. At the same time, a list of animation files included in the specified period is displayed (step Sc8). Next, the user determines the length and order in which the displayed animation is reproduced (step Sc9). Thereafter, the animation file is reproduced, and the moving image simulation is displayed (Step Sc10). If there is a problem with the display, the user again determines the length and order in which the displayed animation is reproduced (step Sc9).
[0024]
(4) Progress Status Management FIG. 7 is a flowchart showing the progress status management process. The user inputs the actually completed construction date into each schedule item (step Sd1). The input construction date is written in the project database 11 corresponding to the schedule item. Next, the user designates a date when comparison is desired (step Sd2), and then presses an execution button (step Sd3). When the execution button is pressed, the schedule and the actual construction status at the designated date are read from the project database 11 and displayed, and the progress difference between the schedule and the actual construction status is highlighted (step Sd4). .
[0025]
As described above, according to the construction work management apparatus according to the present embodiment, three-dimensional model data created by three-dimensional CAD for examining the constructability (workability) in the work plan and verifying the schedule can be simplified. By using the created three-dimensional model data, these studies that have been conventionally performed on paper can be performed more efficiently and in detail. This can provide the effect of shortening the time of the construction plan and reducing the risk for additional cost due to a planning mistake.
[0026]
In addition, since these products are electronic data, it is easy to share information with in-house project stakeholders, and it is possible to reduce the time required for unifying the recognition of the construction sequence and the construction method as compared with the related art.
In addition, since this system is operated at the site office and can be used to explain the construction plan for the sub-contractor, the will can be unified quickly for the sub-contractor, as described above. But you can expect to save time.
In addition, by using the information for explanation and presentation of the construction plan to the customer, the presence of the company can be enhanced and the company can be differentiated from other companies.
[0027]
【The invention's effect】
According to the present invention, it is possible to obtain the effect that the schedule and the progress can be visually grasped at a glance by the graphic. Further, according to the present invention, there is obtained an effect that a simulation of carrying in and installation of a device can be performed in accordance with the progress of a schedule.
