Description

  The present invention relates to a volume management system used in volume management in various works such as plant work, construction work, and civil engineering work.

  In various works such as plant work, construction work or civil engineering work, especially large-scale work such as plant work, the contractor side (constructor side) who undertakes construction work under the design management of the orderer side (administrator side) It is widely practiced to proceed with construction based on a predetermined construction progress plan and to manage the volume with respect to the progress of the construction. In volume management, the relationship between the planned progress status and the actual progress status, and the relationship between the actual cost, which is the actual cost required by the contractor according to the progress of the construction, and the execution budget, which is the cost planned by the manager. Etc. are managed. For example, the contractor submits an application for acceptance of the actual progress of construction work on a monthly basis and charges a cost based on the actual cost. The manager assesses the application, and the work is progressing as planned, and the billing cost is executed. If there is no problem in relation to the budget, confirm the assessment and pay the cost. Regarding such volume management, examples disclosed in Patent Document 1 and Patent Document 2, for example, are known.

  Here, in the construction as described above, there are not a few cases in which partial design changes are made during the construction. Such design changes are generally made to the extent that fluctuations in actual costs can be absorbed by the margin of the execution budget. However, there are cases where actual costs increase beyond the expectations of the manager. is there. In such a case, a cost request exceeding the execution budget is charged from the builder side to the manager side. If that happens, the manager will need to consider the appropriateness of the billing costs and negotiate with the contractor to reduce the billing costs. During that time, the construction will be suspended. This may result in a delay in construction, or even a short circuit on the manager side.

Japanese Patent No. 3262522 JP-A-9-26995

  The inventors of the present invention have examined in detail how to manage the volume for problems such as delays in construction and shortage of funds associated with the above-described design change. As a result, it was found that there was a problem in the commonality of both the contractor's and manager's perceptions regarding the volume of work that had been done. In other words, there is a discrepancy between the contractor's side and the manager's side regarding the amount of work that has increased due to the design change. It was supposed to lead to a situation that required work such as negotiating a reduction in billing costs to the side. From this, it is possible to recognize the volume information with higher objectivity on both the construction side and the manager side, that is, the volume information that allows the manager side to easily obtain a concrete image of the construction volume. If it can be shared by both the contractor side and the manager side, it can be said that it is possible to effectively avoid problems such as delays in construction and shortage of funds due to design changes.

  The present invention has been made on the basis of such knowledge, and makes it possible to provide highly objective volume information that enhances the commonality of both the construction side and the manager side with respect to the volume. The challenge is to build a volume management system.

  In the present invention, in order to solve the above-mentioned problem, in the yield management system used to manage the progress status of the construction that the contractor proceeds, the administrator side stores the CAD model inclusion data including the CAD model related to the construction of the yield management target. Provided to the construction side, the construction side creates the CAD model base construction progress status data by superimposing the construction progress status data relating to the actual progress status of the construction on the CAD model inclusion data, and the CAD model base construction progress It is characterized in that an application for acceptance of the construction progress status to the manager side can be made using the status data.

  As described above, since the application for acceptance of the construction progress status can be made using the CAD model-based construction progress status data created based on the CAD model related to the volume management target construction, In the inspection of the status, it becomes possible to grasp the contents of the construction and the progress status in an image. Therefore, the commonality of both the construction side and the manager side regarding the volume can be further increased.

  Further, in the present invention, the CAD model / work process link data created by linking work processes related to the progress plan for each work unit of work to the CAD model as the CAD model inclusion data for the volume management system as described above. I use it.

  By using the CAD model / work process link data in this way, creation of CAD model-based construction progress status data is facilitated, and the construction progress status is more easily grasped.

  The present invention also includes a link processing unit for creating a CAD model / work process link data by linking the work process to the CAD model for the volume management system as described above, and the construction progress status data as the CAD model. A construction progress state data creating unit that creates the CAD model base construction progress state data superimposed on the work process link data is provided.

  Further, in the present invention, a three-dimensional CAD model is used as the CAD model in order to further enhance the image visualization effect in the volume management system as described above.

  According to the present invention as described above, it is possible to provide highly objective volume information that enhances the commonality of both the construction side and the manager side with respect to the volume.

And used for information disclosed by the information disclosure unit 4. Predictive work process data D10 is data obtained by predicting the work process after the acceptance at the work process review simulation, and is output to the outside as a reference when the administrator reviews the work process every time the acceptance is performed. Used. By making the predicted work process data D10 available in this way, the administrator can review the work process more efficiently.

  Further, the work process simulator unit 16 outputs a work delay / delivery delay alarm instruction D11 for issuing an alarm about a sign of work delay or delivery delay from the relationship between the actual progress state and the planned progress state. To do. When the work delay / delivery delay alarm instruction D11 is output and an alarm is issued, the administrator takes measures to avoid the work delay and the like, which is re-input as the work process review condition data D8, and based on that The work process review simulation is performed again, and recommended work process data D12 is output. The recommended work process data D12 is data describing a work process that can be recommended for avoiding work delay or the like by work process review simulation performed based on the work process review condition data D8 that avoids work delay or the like. It is output to the outside and used as a reference when the manager reviews the work process to avoid work delays.

  The transaction settlement processing unit 17 generates a permission condition D13 related to payment for the progress work for which the application for inspection has been applied, outputs it to the outside, and outputs inspection result information D14 to the public information database unit 14. Payment is usually performed by electronic payment. In the case of electronic payment, the payment permission condition D13 is a payment permission condition for electronic payment. Generation of the payment permission condition D13 and the inspection result information D14 by the transaction settlement processing unit 17 is performed in response to the input of the inspection application data D6, the evaluation data D7, and the assessment confirmation D15 instructing the final assessment in the acceptance.

  The application unit 3 functions to create various application data to be submitted by the contractor to the manager, and includes a construction progress state data creation unit 21 and an application data creation unit 22.

  The construction progress status data creation unit 21 superimposes the local construction status data, that is, the construction progress status data D16, which is input by the contractor as data regarding the actual progress status of the construction, with the CAD model / work process link data D3. It functions to create CAD model-based construction progress status data D17 based on the model. For the process of superimposing the construction progress state data D16 on the CAD model / work process link data D3, for example, a technique of coloring the CAD model / work process link data D3 according to the work progress state can be used.

  The application data creation unit 22 functions to create the construction bidding file D18 and the inspection application file D6. The construction bidding file D18 is created in a file format corresponding to the construction construction inquiry file D4 when receiving a construction construction inquiry by the construction construction inquiry file D4 and bidding for it. The acceptance application file D6 is created in a predetermined file format as acceptance application data including the CAD model base construction progress status data D17.

  The information publishing unit 4 publishes information related to the construction progress status (status) and inspection results, etc., among the various data created by the volume management unit 2 to the manager, the installer, and the final customer of the construction. For this purpose, the information disclosure unit 4 includes a construction progress state information disclosure unit 23 and an inspection / work process prediction / result information disclosure unit 24. The construction progress status information disclosure unit 23 obtains the construction progress status information D19 in a predetermined file format including the CAD model base construction progress status data D17 from the public information database unit 14 and publishes it. On the other hand, the inspection / work process prediction / result information disclosure unit 24 obtains the inspection / work process prediction / result information D20 from the public information database unit 14 and publishes it. Such an information disclosure unit 4 performs information disclosure using a server for information disclosure.

  Details of the CAD model / work process link processing unit 13 will be described below. FIG. 2 shows the configuration of the CAD model / work process link processing unit 13. The basic function of the CAD model / work process link processing unit 13 is to create CAD model / work process link data D3 by linking work process data D2 to CAD model data D1. In the present embodiment, in addition to this function, a function for creating a construction work inquiry file D4 and a work ordering file D5 is also imposed. Therefore, the CAD model / work process link processing unit 13 includes a preprocessing unit 31, a link processing unit 32, a work amount totaling unit 33, a link processing unit database unit 34, an electronic file input unit 35, and an electronic file creation unit 36. I have.

  The preprocessing unit 31 performs WBS processing on the CAD model data D1. That is, a CAD model for construction is divided into work units corresponding to the work units in the work process data D2 described above, that is, work units based on tree-structured hierarchies, and the tree-structured hierarchical work units are defined as CAD model data D1. The WBS-converted CAD model data D1-w is generated and provided to the link processing unit 32.

  The link processing unit 32 links the CAD model data D1 (WBS CAD model data D1-w) provided from the preprocessing unit 31 with the work process data D2 fetched from the work process database unit 12 to create a CAD model / work. Process link data D3 is generated and output to the link processing unit database unit 34. Linking by the link processing unit 32 is performed by superimposing the scheduled work completion date for each work unit included in the work process data D2 on the WBS CAD model data D1-w in an appropriate form. The link processing unit 32 also generates work amount totaling data D21 and provides it to the work amount totaling unit 33. The work amount totaling data D21 is data on attributes of routine work such as welding points and support attachments assigned to each of the above-mentioned minimum work units in the CAD model data D1.

  The work amount totaling unit 33 calculates the work amount total data D22 by totaling the work amount in the construction work, in particular, the work amount of the routine work based on the work amount totaling data D21, and generates the work amount totaling data D22. Output to.

  The link processing unit database unit 34 stores and accumulates the CAD model / work process link data D3, work amount totaling data D22, and the like, and provides these data as required.

  The electronic file input unit 35 receives electronic files such as an inspection application file D6 and a construction bid file D18 input from the outside.

  The electronic file creation unit 36 creates the construction work inquiry file D4 and the work order file D5 as electronic files using the CAD model / work process link data D3, work amount totaling data D22, and the like. These electronic files have a common file format with other various electronic files (such as the inspection application file D6 and the construction bid file D18) handled by the volume management system 1.

  FIG. 3 shows an example of the configuration of the electronic file 40 handled by the volume management system 1 for the construction work inquiry file D4. The file format of the electronic file 40 is basically common to other various electronic files, and includes a header 41, image data 42, routine work details 43, non-standard work details 44, construction worker status data 45, construction personnel. Each column includes text data 46, field manager assessment status data 47, and field manager assessment text data 48.

  The header 41 has fields such as CAD model work block code, WBS, construction completion date, order date, order number, orderer code, order number, construction contractor code, etc., and these data are recorded.

  In the image data 42, CAD model / work process link data D3 and CAD model base construction progress status data D17 for the work block recorded in the CAD model work block code in the header 41 are recorded. In the image data 42, as shown in the example shown in the figure, a work unit based on a tree structure hierarchy is displayed as a node 49 of the tree structure, and the CAD model is selected at the work unit level by clicking the node 49 on the display screen. The work process link data D3 and CAD model base construction progress status data D17 can be displayed.

  In the routine work description 43, the work amount totaling data D22 automatically counted by the work amount totaling unit 33 based on the attributes of the standard work included in the CAD model data D1 in advance is recorded as details. The standard work details 43 include fields such as standard work items, quantities, and standard costs.

  In the non-standard work details 44, for example, a record of non-standard work such as alignment adjustment and anti-vibration measures is made by manual operation by both the manager and the installer.

  In the construction practitioner status data 45, the construction status (construction progress state) is recorded by the construction practitioner who performs the construction practice. The record is automatically reflected in the CAD model / work process link data D3 or CAD model base construction progress status data D17. The construction practitioner status data 45 includes fields such as estimated deviation, construction deviation, construction start, construction completion, inspection completion, construction trouble, and process delay.

  In the construction practitioner text data 46, the construction practitioner inputs text data as necessary.

  The field manager assessment status data 47 records data relating to the assessment performed by the site manager who supervises and manages the construction practice performed by the construction practitioner with respect to the progress report from the construction practitioner. The record is automatically reflected in the CAD model / work process link data D3 or CAD model base construction progress status data D17. The field manager assessment status data 47 includes fields such as acceptance completion, rejection assessment, construction freeze, payment completion, and payment incomplete.

  The site manager inputs text data to the site manager assessment text data 48 as necessary.

  Here, there are construction practitioners and site managers on the contractor side. When the site manager assesses the progress report from the construction practitioner and accepts it, the site manager applies for acceptance based on it. The file D6 is created and an inspection application is made to the administrator.

  Next, the operation of the volume management system 1, that is, the volume management method by the volume management system 1 will be described. Volume management basically includes the CAD model related to the volume management target construction as information that visualizes the contents and progress of construction with the involvement of the manager and the contractor as described above. This is done through the exchange of various electronic files created in common.

  In addition, the basic processing required for volume management is the relationship between the planned progress and the actual progress, and the actual costs that are actually required by the contractor according to the progress of the construction, and the manager's side. It is a process about the relationship of the execution budget which is the expense which was planned in (4). In other words, for example, the contractor submits an application for acceptance of the actual progress of construction work on a monthly basis, charges for the actual cost, the manager confirms the submitted progress, the manager assesses the application, and the construction is scheduled This is a process that is basically required for volume management, in which the process of paying the cost if the billing cost is related to the execution budget is acceptable. In the volume management system 1 of this embodiment, in addition to such basic volume management functions, each process such as construction work inquiry, construction bidding, construction ordering, information disclosure, work process review, and the like related processes are performed. Also has a function for performing processing using an electronic file in a common file format. Hereinafter, each of these processes performed in the volume management system 1 will be described sequentially.

  In the operation of the volume management system 1, processing up to the start of construction is first advanced. Prior to the start of construction, each process of construction inquiries, construction bids, and construction orders is performed. Prior to these processes, CAD model / work process link data D3, which is the basis of the image visualization information, is created. The CAD model / work process link data D3 is created in the CAD model / work process link processing unit 13 as described above. That is, the pre-processing unit 31 performs WBS processing on the CAD model data D1 extracted from the CAD model database unit 11 to create WBS-based CAD model data D1-w, and performs link processing on the WBS-based CAD model data D1-w. The unit 32 links the work process data D2 from the work process database unit 12 to create CAD model / work process link data D3. The CAD model / work process link processing unit 13 creates work amount totaling data D21 simultaneously with the creation of the CAD model / work process link data D3. The creation of these data is performed in units of the above-described work blocks.

  When the CAD model / work process link data D3 and work amount totaling data D21 are created, a construction work inquiry file D4 incorporating these data is created by the CAD model / work process link processing unit 13. The created construction work inquiry file D4 is sent to a bid participant (construction contractor) through a communication network such as the Internet.

  The bid participant who has received the construction work inquiry file D4 determines the scope of the work, that is, the work scope by the CAD model / work process link data D3 in the image data 42 of the construction work inquiry file D4 or the work amount totaling data D21 in the fixed work details 43 Confirm the construction blocks and work units that the bid participants can share, and consider deviations. Here, the deviation is a deviation between the construction content requested by the ordering side and the construction content that can be performed by the order receiving side. For example, if the ordering side requests construction with a content of “10”, but the construction content that can be performed by the order receiving side is “8”, there will be a deviation of “2”, which is a deviation. It becomes. In the case of bidding after confirming the scope and consideration of the deviation, the bid participant creates a construction bidding file D18 by inputting the data in a text format etc., if there is a deviation, and creates it as a manager ( At this time, it is sent to the orderer.

  The manager who has received the construction bidding file D18 confirms the contents thereof, and if the bidding applicant is selected, creates a construction ordering file D5 and sends it to the bidding applicant. At this time, there is a deviation in the construction bidding file D18. If it is accepted, the CAD model / work process link data D3 and the work amount totaling data D21 are changed to reflect the deviation if necessary. The construction order file D5 is a contract for construction ordering. And, as a result of various negotiations, etc. that occur between the manager and the contractor in accordance with the progress of the work after the work order has been placed, when the work design changes and the CAD model / work process link data D3 change accordingly, etc. The change history is reflected in the construction order file D5.

  When a construction order is made to the contractor determined as described above and the construction starts, the contractor then applies for acceptance of the progress status of the construction, for example, on a monthly basis, and charges the actual cost. The management side assesses the submitted progress status and cost claim, and the construction is progressing as planned, and if the billing cost is not related to the execution budget, payment will be made. Repeat until construction is complete.

  The application for inspection of the construction progress status by the installer is made by creating an inspection application file D6 and sending it to the manager. The acceptance application file D6 is created using the application unit 3 as described above. At this time, the CAD model work block search command D23 is input, and the CAD model for the CAD model work block to be accepted is entered. The work process link data D3 is taken from the public information database unit 14 into the construction progress state data creation unit 21. Then, construction progress status data D16 is input, and this is superimposed on CAD model / work process link data D3 to create CAD model base construction progress status data D17.

  The manager who has received the acceptance application file D6 assesses it for acceptance. In the acceptance inspection, the actual progress state is grasped by the CAD model base construction progress state data D17 included in the acceptance application file D6 and compared with the planned progress state. The actual cost is compared with the execution budget, and if there is no problem, the assessment is confirmed and the assessment confirmation D15 is input to the transaction settlement processing unit 17.

  To refer to the CAD model base construction progress status data D17 in the acceptance application file D6 in the acceptance inspection, click the node 49 in the column of the image data 42 in the acceptance application file D6 to select the CAD model base construction progress status data at the work unit level. D17 is displayed. The CAD model base construction progress status data D17 is data based on the CAD model, and provides highly objective volume information that increases the commonality of both the construction side and the manager side with respect to the volume. When there is a partial design change, yield information that increases the commonality of recognition with a specific image of the amount of work of the design change part is given. For this reason, it is possible for the manager side to effectively avoid problems such as delays in construction and shortage of funds due to design changes.

  Upon receipt of the assessment confirmation D15, the transaction settlement processing unit 17 generates a permission condition D13 related to payment for the progress work for which the acceptance application has been applied, outputs it to the outside, and outputs the inspection result information D14 to the public information database unit 14 Output to.

  If there is a problem with the progress status or actual cost in the acceptance inspection, the manager and the contractor will negotiate the problem. When there is a problem in the progress state, a work process review simulation is performed by the work process simulator 16 as described above. Further, when it is determined that there is a sign of work delay or delivery delay from the progress status of the application for acceptance, an alarm is issued as described above. When an alarm is issued, the administrator takes measures to avoid work delays. If the negotiation between the manager and the contractor is concluded, the assessment settlement D15 is input to the transaction settlement processing unit 17.

  As described above, while the application for inspection and inspection are periodically repeated as described above, the information disclosure section 4 provides information on the work to the manager, the installer, and the final customer of the construction. Information is made public. The information to be disclosed is construction progress status information D19 and inspection / work process prediction / result information D20 including a CAD model that is the basis of the image visualization information. By making such information public and sharing important information about construction among managers, contractors, and end customers of construction, volume management and negotiations associated with it can be performed more smoothly. .
