In addition, for example, even if there is material necessary for one person involved and material unnecessary for another person, it is necessary to sort out a large amount of information, and it takes time and effort for information processing, and construction May be delayed. In particular, in the reconstruction project, there are many uncertain factors and a large amount of information, so the above-mentioned problems are remarkable.

  The present invention has been made from the above technical background, and an object thereof is to provide a technology capable of providing necessary information to each of a plurality of construction parties at an appropriate time. With the goal.

In order to solve the above problems, the construction management system of the present invention according to claim 1 comprises a construction orderer and a plurality of construction operators, each of whom a construction manager who is an agent of the construction orderer operates, operate on each of them. and a client device, a communication line said plurality of client devices are electrically connected, the connected plurality of the via communication lines electrically to the client device, disclose construction information for the plurality of work parties or An external storage unit including a server apparatus which selects and executes non-disclosure and disclosure timing in the case of disclosure, the server apparatus storing a server program necessary to execute processing and information on construction; Also, the server program is read and information on construction is uploaded from the client device via the communication network. And a main control unit for downloading to the client device, wherein the server device selects and executes permission or non-permission of processing of the information to the plurality of construction personnel, and the server device is configured to While disclosing specific information on construction and permitting the writing of opinions on construction, the construction manager should maintain the technical neutrality at each stage of design, ordering and construction while maintaining the construction neutrality. It is characterized by using a method of performing all or part of various management tasks on the part of the party.

  According to the present invention, it is possible to provide necessary information to each of a plurality of construction parties at an appropriate time.

It is a block diagram which shows an example of the construction management system by a common CM system. It is an organization chart of an example of a construction person concerned related to reconstruction construction using a construction management system concerning one embodiment of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS It is a block diagram of an example of the construction management system which concerns on one embodiment of this invention. It is a circuit block diagram which shows the structural example of the server apparatus of FIG. It is a figure showing an example of information name about construction, disclosure timing of the information, and a disclosing person.

  Hereinafter, an embodiment as an example of the present invention will be described in detail based on the drawings. Note that, in the drawings for describing the embodiments, the same components are denoted by the same reference symbols in principle, and the repeated description thereof is omitted.

  The civil engineering work and the construction work of this embodiment are, for example, construction related to a reconstruction project such as a reconstruction urban area maintenance project or a disaster public housing maintenance (hereinafter referred to as a reconstruction construction). A management (hereinafter abbreviated as CM) method is adopted.

  In the CM method, the construction manager who is the agent of the construction orderer, while maintaining technical neutrality at each stage of design, ordering and construction, stands on the side of the construction orderer and considers the design and construction order system. It is a method to execute all or part of various management tasks such as examination, process control, quality control and cost control.

  FIG. 1 shows a configuration diagram of an example of a construction management system according to a general CM method. The construction orderer C making a design supervision contract with a design company Sa and making a construction contract with a plurality of specialized vendors Sb is the same as the batch ordering system. Also, the design company Sa performing the design supervision of the specialized company Sb is the same as the batch ordering system. What is different from the collective ordering method is that the construction manager CMR that has made a CM contract with the construction orderer C implements support management for the construction orderer C and performs business management management for the design company Sa At the same time, it is necessary to carry out construction management management for a plurality of specialized companies Sb.

  The features of the construction management system of this embodiment adopting the CM method are mainly as follows. That is, the contracting party is determined by the public offering type proposal method (technical proposal) and price negotiation. In addition, it includes early work to start construction promptly, and next work to be implemented at the stage when the scope and plan of the maintenance have not been decided at present and conditions are ready. The business cost is the business cost plus the management fee, and the standard management fee rate is, for example, 10% of the business cost. In addition, if the value engineering (VE) proposal reduces the cost from the base price agreed upon by the price negotiation, for example, 50% of the cost reduction amount is paid as an incentive fee. In addition, based on the risk previously confirmed by the orderer and the orderer, an upper limit is set for the reference price. Also, the open book method is adopted, the information on all the costs is disclosed to the orderer, and the orderer or the external third party performs the audit. In particular, with regard to Open Book, it is the evaluation standard to carry out based on the “standard draft” attached to the public announcement material. Therefore, in this business, all the evidence concerning payment of the cost incurred in the business Submit to the client. Payment to the vendor is made by having the vendor open a dedicated account for work. Conduct operations such as conducting quarterly audits by third parties (auditing firms, etc.).

  When such a CM method is adopted, for example, since the clarification of the cost structure and the transparency of the ordering process can be ensured, accountability to the nearby residents can be improved. In particular, at each stage of the reconstruction work, the merits and demerits of the multiple options proposed by the construction manager CMR can be examined and determined, and the multiple strategies for each task can be compared to proceed with the business, and It can improve the transparency of the decision making process. It can also increase the opportunity for ordering to local construction companies and local specialists. In addition, it is possible to promote cost management reinforcement (cost reduction and construction period shortening by specialized examination and analysis). Furthermore, all records are stored, and information disclosure can be flexibly handled. From such a point of view, the construction management system of this embodiment adopting the CM method is suitable for reconstruction work.

  Next, FIG. 2 shows an organization chart of an example of construction-related persons related to the reconstruction work using the construction management system of the present embodiment.

  In addition to the design and construction company S, persons involved in reconstruction work include, for example, Y town T, business promotion organization PP, consultation related organization R, external third party organization TP, cooperative CP and neighborhood resident NR etc. There are several other construction parties involved.

  Here, there is a case where Y town T where reconstruction work is carried out consigns reconstruction work to the project promotion organization PP, and the business promotion organization PP orders reconstruction work to the general management engineer S1 of the design and construction company S It is illustrated. For example, there are prefectures and police stations where various permission applications are required at the time of construction. In addition, the external third party TP includes, for example, an audit corporation. The cooperative CP includes, for example, agricultural cooperatives and fishing cooperatives.

  The integrated management engineer S1 of the design and construction company S corresponds to the construction manager CMR described above, and manages various operations such as survey, survey, design and construction collectively. Therefore, under the control of the general management engineer S1, a survey, survey, design general management engineer S2 and a construction general management engineer S3 are disposed.

  Survey, surveying and design generalization management engineer S2 is a technician who comprehensively manages the work related to surveying, surveying and design before construction, and under the management, surveying chief engineer S4, geological survey chief technology A person S5 and a design engineer S6 are assigned. Then, under the supervision and guidance of each of the chief engineers S4 to S6, each operation is advanced by the surveying specialist S7, the investigation specialist S8, the design specialist S9, the equipment supplier S10, and the like.

  On the other hand, the construction general management engineer S3 is an engineer who comprehensively manages the work related to the construction, and under the management, a site agent (supervision engineer) S11 is arranged, and under it, the anti-collection transfer department A chief engineer S12 and a section rearranging section chief engineer S13 are disposed, and further below each, a plurality of responsible technicians S14 are disposed. Then, under the supervision and guidance of each responsible engineer S14, the construction is advanced by a plurality of construction specialists S15 and equipment suppliers S16.

  Such a design and construction company S has, for example, a joint venture (joint venture (JV)) in which a plurality of different companies etc. jointly operate. In addition, in the selection of specialized traders S7 to S10, S15, S16, etc., local traders are given priority for the recovery and revitalization of the regional economy in the afflicted area. The general management system engineer S17 performs, for example, operation, maintenance, and maintenance of the construction management system.

  Next, FIG. 3 shows a configuration example of a construction management system of the present embodiment.

  The construction management system 1 of the present embodiment utilizes a cloud infrastructure, and has a server apparatus SV, a plurality of client apparatuses CL, and a communication network (communication line) NW electrically connecting them. ing.

  The server apparatus SV is a management station having a construction management program for managing civil engineering work, construction work, and the like according to the present embodiment, and has a role of providing various services related to construction in response to requests from each client apparatus CL. doing. Although not particularly limited, the server apparatus SV is installed at a data center remote from the construction site.

  The client device CL is a device operated by each of the plurality of construction personnel described above, and can be network-connected, for example, a personal computer, a mobile personal computer, a portable information terminal such as a tablet or a portable telephone, etc. The device is in use. The client device CL has an input unit and a display unit corresponding to each model. For example, when the client device CL is a personal computer or the like, a keyboard, a mouse or the like is used for the input unit, and a liquid crystal display or the like is used for the display unit. When the client device CL is a tablet or the like, an input unit such as an operation button or the like is disposed in the display surface of the display unit such as a liquid crystal display or the like.

  The communication network NW is formed by, for example, a public line such as an integrated services digital network (ISDN) or the Internet. Therefore, the neighborhood residents NR and the cooperative CP can also freely access the web page provided by the server apparatus SV.

  A construction ID except for the above-mentioned neighborhood resident NR and cooperative CP is given a unique ID (Identification) and a password. And each construction person concerned (except the neighborhood residents and the cooperative CP) accesses the designated web page from each client device CL by a web browser etc., and relates to the construction by inputting a unique ID and password. It is possible to browse, upload or download information. An ID and a password are also assigned to each engineer and specialized contractor (S1 to S17) in the design and construction contractor S, and it is possible to access the server apparatus SV.

  Although a unique ID and password have not been assigned to the nearby resident NRs and cooperatives CP, various information related to construction can be viewed or commented by accessing a designated web page from the client device CL using a web browser or the like. It is possible to write etc. Information that can be browsed by neighboring residents NR and cooperative CP is, for example, the situation of the site (photograph etc.) in line with the progress of construction, the utilization of local companies, the amount of contracts, the progress of contracts and payments (amount and progress) And it is limited to specific information such as the progress status etc. of the construction target.

  Thus, in this embodiment, construction such as Y town T, project promotion organization PP, consultation related organization R, external third party organization TP, design and construction company S, neighborhood resident NR, and cooperative CP etc. Since the parties can share information with each other, the business can proceed quickly. In particular, in the construction management system of the present embodiment, by sharing the land right information in cooperation with the map tool, the work can be performed while sharing the information related to the construction approval and land acquisition which greatly affects the process among the entire parties. You can go ahead. Moreover, the transparency of various matters by information disclosure can be improved.

  In addition, since paperwork can be simplified (documentation is computerized), it is possible to concentrate on the original business for business promotion. In addition, since a large number of documents (e-mails and attached files) required each month can be processed by a limited number of personnel, work can be streamlined. In addition, secondary processing and arrangement of time-consuming information can be simplified. These can prevent business delays. In addition, information can be consolidated and integrated, and information (history and trail) can be accumulated. Therefore, quick decision-making and implementation can be achieved without space and time constraints.

  In addition, since information can be shared in the design and construction company S, the construction team and the contents can be scrutinized at each design stage, and the design contents can be made more in accordance with the implementation work. In addition, appropriate personnel can be assigned in the work. Also, adjustment of the schedule can be facilitated. Moreover, while making it possible to clarify the role assignment by creating a confirmation about the role assignment, it is possible to change the role assignment flexibly according to the construction. By these, design and construction can be smoothly advanced.

  In addition, by linking data with the individual company accounting system and the open book correspondence format using a cloud, it is possible to largely omit the work of creating detailed checks of cost and accounting documents in consideration of accounting audits and the like. For this reason, simplification of paperwork can be achieved. In addition, by creating a material indicating the appropriateness of the cost, it is possible to improve the efficiency of confirmation work and reduce the cost, and to control the cost strictly. In addition, the cost management sheet (created by the contractor) is shared with the orderer on the cloud (by the orderer on the cloud) by creating a rulebook that clearly shows the flow of cost etc. while maintaining the cost inclusion list. You can access the file to check the cost increase and decrease reasons, and authorize the incentive). By these, it is possible to standardize audit contents. In addition, the transparency of cost control operations can be improved.

  Next, FIG. 4 is a circuit block diagram showing a configuration example of the server apparatus of FIG.

  The server device SV electrically connects the main control unit (central processing unit) CPU, the main storage unit MM, the communication unit SU, the input unit NU, the display unit DU, the printing unit PU, the external storage unit ES, etc. And a bus BS, and is electrically connected to the communication network NW via a communication unit SU on the bus BS.

  The main control unit CPU is a functional unit that controls the server device SV, and realizes various functions by reading and executing various programs installed in the external storage unit ES through the bus BS.

  A server program necessary for the server apparatus SV to execute processing is stored in the external storage unit ES, and various data can be transmitted via a communication network by the function of CGI (Common Gateway Interface) or FTP (File Transfer Protocol). It is possible to upload from the client apparatus CL or download to the client apparatus CL via the NW. The data uploaded to the server SV is managed on the date and time of upload, so that the latest data can be known.

  In addition to the server program and the construction management program, the external storage unit ES includes, for example, a process management file F1, a finished form management file F2, a quality management file F3, a conference management file F4, a budget file F5, a mail file F6, Information on construction such as the related party access right file F7 etc. is stored.

  The process management file F1 includes, for example, progress, problems, survey, surveying, design, soil transportation, water and sewage maintenance, removal plan, backfill ground reinforcement, impact analysis and countermeasures by tide embankment maintenance, diversion embankment quality, around Contains various files of environmental monitor, license application, report and risk management.

  The progress status file stores, for example, work progress information, a progress status chart, and a permit application consultation process schedule. In the license application consultation schedule, for example, license application items, license acquisition period, notification time, etc. are recorded. In the file of the task, for example, the issues and the task diagram etc. are stored. The issues and issues map is a list of issues and countermeasures that occur at each event. For example, risk to process, cost (risk sharing table, cost control meeting), analysis results from preliminary survey results, local needs And complaints, weather information, coordination with other projects (prefecture projects) and issues linked to traffic volume and location are recorded. For example, design documents are stored in the design file. For example, detailed design documents and supplementary materials are recorded in the design documents. The file of impact analysis and measures by seawall construction, for example, records the results of boring survey and its analysis and analysis results. Various environmental measurement value data are recorded in the file of the peripheral environment monitor. In this environmental measurement value data, measurement values of measurement date and time, measurement place (around work site and transportation route) and various elements (noise, vibration, water quality of discharged water, etc.) are stored. This environmental measurement is carried out regularly for safety and consideration of the surrounding environment.

  The finished form management file F2 is a file for managing the accuracy of the order standard of the orderer and the constructed structure. In this file, for example, a final management table, a measurement result list, and a final management chart are recorded. The information on the finished form management file F2 is the actual information to be input for each division of work (one day to several months), for example, construction date (book entry date), work group name, actual quantity, items required for construction And information such as quantity (one or more), unit price of work group, etc.

  The quality control file F3 includes, for example, a collection of design conditions (a collection of unified design conditions for each design unit), product inspection (intermediate results and final results), and a list of issues (conventional field survey of specialized contractors, JV design team, and Business issues etc.) extracted at the start of construction meeting are recorded.

  The conference body management file F4 is a file for managing information of various conferences, and for example, the minutes of a regular conference, a briefing session, a design conference, an open book conference, safety management and a related books conference are recorded. . The regular meetings include a buyer liaison conference, related other business liaison conferences, an information sharing conference, a business team liaison conference, a specialist contractor conference, a joint liaison conference and a liaison conference.

  The budget file F5 is a file that specifies the budget of each process of construction in detail, and for example, for each work of each process, work number, work name, work quantity, component item name required for work, item quantity Information such as unit price per unit of work is recorded.

  The mail file F6 is a file for storing an electronic mail transmitted and received between the client apparatuses CL of the construction parties.

  In the related person access right file F7, types of access right that each of the construction related parties can execute for each of a plurality of pieces of information related to the construction are recorded. For example, it is as follows.

  First, the participant access right file F7 is divided into a recording area of a person who owns a unique ID and password, and a recording area of a person who does not own a unique ID and password. In the recording area of the person who owns the unique ID and password, the unique ID and password, owner name of the ID and password (construction related person name), accessible information name and executable access right for each information The kind of etc. is recorded. The type of access right includes, for example, the right to view information and the right to process information (such as writing or correcting a document, attaching or deleting a drawing or a photo, etc.).

  On the other hand, in the recording area of the person who does not possess the unique ID and password, the names of the specific information that can be browsed and the types of accessible rights are recorded. Specific information includes, for example, the site status (photographs etc.) in line with the above-mentioned progress status of construction, utilization status of local companies, contract amount, progress status of contract and payment (price and progress rate), problem, construction target There is an advance situation etc. In addition to the right to browse the specific information, the type of access right in this case has the right to be able to write an opinion on construction.

  Here, in the network construction management system, a large amount of information can be simultaneously provided to a plurality of persons involved in the construction, but if information is simultaneously provided to a plurality of persons involved in the construction, confusion may result. There is a problem that it will come and block the progress of construction.

  For example, in construction work or civil engineering work, the order of subsequent steps, required materials, equipment used, cost of construction, etc. will change according to the finished form, so some data necessary for a person involved in construction may not It may be a material with an uncertain element for construction personnel. In addition, for example, even if there is material necessary for one person involved and material unnecessary for another person, it is necessary to sort out a large amount of information, and it takes time and labor for information processing, and in fact May be delayed. In particular, in the reconstruction project, there are many uncertain factors and a large amount of information, so the above-mentioned problems are remarkable.

  Therefore, in the construction management system 1 of the present embodiment, the disclosure or non-disclosure of information to a plurality of construction persons is selected and executed. For example, it is as follows.

  First, any construction party having a unique ID and password accesses a designated web page from the client device CL by a web browser or the like, and inputs the unique ID and password. Then, in the server apparatus SV, referring to the concerned person access right file F7 of the external storage unit ES, whether or not there is the name of the information to be accessed in the column of the person concerned with construction (unique ID and password) To judge. And if there is a name of information to be accessed, the information is disclosed. On the other hand, when there is no name of the information to be accessed, the information is not disclosed.

  Also, similarly, referring to the related person access right file F7 of the external storage unit ES, the work related party processes the accessed information (writing or correction of a document, etc. attachment or deletion of a drawing or a photo etc. Etc.) to determine whether they have the right to If you have the right to process the information, you allow the processing (writing, correction, etc.) of the information, but if you do not have the right to process the information, just process the information (writing or correcting the information by disclosing the information Etc.) is prohibited (prohibited).

  For example, in the case of the business promotion organization PP, since the information name of the task diagram is recorded in the related person access right file F7, the information of the task diagram can be browsed. However, since the business promotion organization PP does not have the processing right to the information on the task diagram, it can not add or modify the information on the task diagram. In addition, it is not possible to access information names that are not recorded in each construction person. For example, in the case of the business promotion organization PP, since the information name of the design document is not recorded in the concerned person access right file F7, the business promotion organization PP can not browse the design document.

  On the other hand, with regard to the neighborhood resident NR and the cooperative CP, the disclosure and non-disclosure of information is selectively executed because there is no unique ID and password. That is, only those specific information will be disclosed to those who do not possess unique IDs and passwords, such as neighboring residents NR and cooperative CP, and information other than specific information will not be disclosed. In addition, it is possible to write an opinion on the construction but not to process other information.

  Here, FIG. 5 shows the name of the information regarding the construction, the disclosure timing of the information, and an example of the discloser. Each piece of information is a part of the plurality of pieces of construction information.

  The permission application discussion schedule is disclosed at any time to Y town T, W prefecture (R) related to construction of Y town, project promotion organization PP and design and construction company S (JV), for example, but other construction relations Not disclosed to the public. The task map is disclosed at any time, for example, to the project promotion organization PP, other business orderer, other business contractor (S), nearby residents NR, local construction company (S) and fishermen's cooperatives (CP). Not disclosed to the public. The design document is disclosed at any time to, for example, the construction team (S) and the specialist (S), but is not disclosed to other construction personnel. The boring survey is disclosed to the construction team (S) at the time of survey and analysis, for example, but is not disclosed to other construction personnel. Although various environmental measurement value data are disclosed at any time to, for example, a specialist (S), they are not disclosed to other construction personnel. The work form management data is disclosed, for example, to the business promotion organization PP when the construction is completed, but is not disclosed to other construction personnel. The orderer liaison conference, for example, is disclosed once a week to the business promotion organization PP and the management team (CMR), but not to other construction parties. Documents (minutes etc.) of related other business liaison conference, for example, business promotion organization PP, management team (CMR), Y town T, W prefecture (R), other business ordering person, other business construction company (S), It will be disclosed once a month but will not be disclosed to other construction personnel. Documents (minutes etc.) of the information sharing meeting are disclosed once a week to, for example, the management team (CMR), the design team (S) and the construction team (S), but not to other construction personnel. The documents of the liaison conference (minutes etc.) are disclosed, for example, to the business promotion organization PP, the management team (CMR), Y town T and W prefecture (R), but not to other construction personnel.

  As described above, in the construction management system according to the present embodiment, the disclosure and non-disclosure of the information for each construction party are selected for each information and executed, thereby making it necessary for each of a plurality of construction parties. Information can be provided at an appropriate time. For this reason, it is possible to prevent the outflow of uncertain information and information overload, and it is possible to prevent the occurrence of confusion in construction operation, so that design, construction and business processing can be smoothly advanced. Therefore, the construction period of the reconstruction work can be shortened. In addition, the cost of construction can be reduced.

  In addition, the person in charge of construction is wrong by selecting and executing permission and impossibility of processing (writing and correction of documents, attachment and deletion of drawings and photos, etc.) for each person concerned with construction. Can prevent the problem of changing information.

  Although the invention made by the inventors has been specifically described based on the embodiments, the embodiments disclosed herein are illustrative in all respects and limited to the disclosed technology. It is not a thing. That is, the technical scope of the present invention is not to be interpreted restrictively based on the description in the above embodiment, and should be interpreted in accordance with the description of the claims only, and the claims It is intended to include all modifications without departing from the scope of the claims and the technical equivalents of the recited technology.

  For example, in the above example, the case where the construction information name accessible for each construction person is recorded in the related person access right file F7 and the construction information not recorded is not accessible is described. For example, the presence or absence of the right to browse the information and the presence or absence of the right to process the information may be recorded for all the construction information, for each construction person. In addition, all construction information may be classified into several groups, and for each construction person, the presence or absence of the right to browse information and the presence or absence of the right to process information may be recorded for each construction information group.

  As described above, the construction management system according to the present invention is useful for a management system of various constructions using a network.
