Description

Construction Work Comprehensive Management System and Method}

The present invention relates to a comprehensive construction management system and method, and more specifically, to a comprehensive construction management system and method for systematically managing the construction process, construction documents, and construction costs that occur during construction work.

As an on-site agent, the site manager of a construction company is responsible for overseeing the entire construction site from the start to completion of the construction site, guiding the subcontractors for each type of work, and ensuring that the construction is completed without exceeding the contract amount according to the contract. The construction company's public affairs department is responsible for estimating, manufacturing drawings, delivery, coordinating construction schedules for all sites, making ready-made claims from building owners, and checking missing information in site documents. In other words, the construction company's public affairs department strives to appropriately cover general management costs and profits according to the contract amount, and the construction company's site manager coordinates the subcontractor's schedule to prevent construction exceeding these profits from occurring, and checks the subcontractor's ready-made invoices to Determine the presence or absence of sex.

However, due to the large amount of information and documents generated at construction sites, it is difficult for site managers to quickly and accurately determine how much profit is left and how much expenses have been incurred at the current point. Therefore, construction companies either perform shoddy work to make up for losses during construction or incur losses after construction is completed. Therefore, construction companies need a system that can immediately check the adequacy of profits and losses for construction costs incurred at multiple construction sites, and a system that allows building owners to easily understand the basis for costs provided by construction companies. It is necessary.

Additionally, construction companies generally manage construction costs by manually creating offline documents or controlling formulas using Microsoft's Excel program. Then, handwritten documents or files are distributed to the construction company site managers in charge of each site to be filled out, and the written documents or files are replied to by mail and e-mail and stored in the construction company's public affairs department.

Documents related to construction work include letters of agreement, expenditure resolutions, subcontract statements, monthly invoices, and contract invoices, and the amount of information exchanged between companies through each document is enormous. However, although documents related to construction work are very important and confidential documents, they are quite vulnerable to security during the delivery process. There is a risk of theft and misdelivery when sending and receiving documents by mail, and there is a risk of exposure to viruses when sending and receiving documents by email. Therefore, there is an urgent need for a system that makes it easy to prepare documents related to construction work, facilitates exchange between companies, and has high security.

Therefore, in the original contract estimate generation step (S210), an estimate of the construction cost expected for building construction work can be generated based on the BIM drawing, and in the original contract details creation step (S220), the original contract information between the building owner and the construction company can be used to generate the estimated construction cost. There is a remarkable effect of being able to understand detailed items in more detail by reflecting them.

In addition, the present invention is to create a original contract document with the BIM drawing based on the original contract information in the original contract document that has been effectively processed from the original contract creation step (S200) by the contract book creation unit 110 of the BIM drawing providing unit 100. It is characterized in that it further includes a primary contract book creation step (S300) in which and related books are created. And in the original contract book creation step (S300), the BIM drawing, the original contract book, and the related books may be linked and stored in the drawing DB 120.

The original contract books referred to in the present invention refer to all design books used when signing a contract with the building owner, and related books refer to all books necessary for construction, such as equipment, electricity, and structure, in addition to design books. In other words, contract documents and related documents may include design drawings and specifications necessary for construction work, and structural calculations and facility-related calculations accordingly. Here, the specification is a document that describes things that cannot be indicated on the design drawing, such as construction methods, types and grades of materials, and precautions at the construction site. In the original contract book creation step (S300), the contract book and related books may be created in one of DWG, IFC, and PDF file formats.

In the case of design documents provided by conventional construction companies, the construction company randomly designates a convenient location and creates a cross-sectional drawing, etc. And at the approval stage, after the structure is entrusted, a structural document is created. At this time, unlike the design document, some design changes may occur in the structural document. In other words, even though the design document and the structural document are not the same, there are often cases where construction is started without recognizing this and the design change part is re-constructed. Reconstruction adds unexpected construction costs and prolongs the construction period, so the process of matching design documents and structural documents in advance is very important.

Therefore, according to the present invention, not only BIM drawings before the original contract between the building owner and the construction company, but also BIM drawings reflecting the original contract information after the original contract can be automatically generated. Accordingly, original contract information is immediately reflected in BIM drawings, which can be used for on-site management, subcontract creation, ready-made claims, and defect repair, and has the notable effect of improving constructability.

Meanwhile, in the primary contract creation step (S200), when the primary contract quotation document and primary contract details document are processed effectively through the electronic approval method, quotation information for the corresponding primary contract is provided in a preset format on the web page implemented from the management server 5. It is characterized by posting some of the historical information. Therefore, there is a significant effect that anyone who has permission to access the web page can easily check the estimates and details of the construction company's order status on the web page.

② Construction management by site managers

Next, in the site management step (S400), site information occurring at the construction site is acquired from the site manager terminal 2 by the site management unit 300, and at least one of the site information and the original contract information is used. This creates field documents.

Referring to FIG. 7, when basic construction documents are generated among field documents, the site management step (S400) is to generate basic construction documents based on the site information and the original contract information obtained from the site manager terminal (2). You can. At this time, in the site management step (S400), the site information including the site name, construction start date, completion date, site manager appointment, and scheduled schedule can be obtained (S401). In the site management step (S400), the original contract information including contract amount, contract date, building owner information, and construction company information can be obtained (S402). And in the site management step (S400), the site information and the original contract information can be used to generate basic construction documents according to the preset basic construction document format stored in the construction site DB (310), and the site information and basic construction commencement documents can be generated. Documents may be stored in the construction site DB 310 (S403).

In addition, site managers generally supervise and guide safety and quality during construction to ensure that subcontractors comply with laws and regulations at the construction site, and record them in the construction log. In generating a smart daily report among field documents, the field management step (S400) of the present invention uses field photos obtained from the field manager terminal (2) and provided from the BIM drawing provider (100) based on artificial intelligence technology. BIM drawings are compared to derive analysis results on form consistency and material suitability, and the site information and analysis results are used to generate a smart daily report.

First, in the site management step (S400), the daily report form stored in the smart daily report DB (320) may be provided to the site manager terminal (2) so that the construction daily report and site photos can be input and uploaded (S404). In the field management step (S400), the smart daily report can be generated when the field information is input according to the daily report form from the field manager terminal (2) (S405). At this time, the site information for generating the smart daily report includes site name, creation date, weather, temperature, today's work details, day's work details, input input status, material input status, outsourced manpower input status, equipment input status, and work instructions. Details may be included. And in the field management step (S400), the field information and smart daily report can be stored in the smart daily report DB (320).

The smart daily report referred to in the present invention is a daily report that combines artificial intelligence technology with the construction daily report prepared by a conventional site manager. The site management step (S400) is based on artificial intelligence technology, and the site photo obtained from the site manager terminal (2) can be compared with the BIM drawing provided from the BIM drawing providing unit 100 or the BIM drawing reflecting the original contract information. (S406). In other words, the consistency of the shape of the part and the suitability of the material can be analyzed by comparing and reviewing the same part among the site photos and BIM drawings constructed at the actual site. And in the field management step (S400), a smart daily report containing analysis results derived based on artificial intelligence technology can be generated (S407).

In addition, looking at FIG. 8, in the site management step (S400), if the site information includes design change information, the design change is sent to the BIM drawing providing unit 100 so that the BIM drawing can be changed according to the design change information. Information may be provided (s408). If it does not contain design change information, it waits until the field information is transmitted from the field manager terminal 2. Then, the present invention includes a BIM drawing change step (S500) in which the BIM drawing is changed according to the design change information by the BIM drawing providing unit 100 and the changed BIM drawing is stored in the drawing DB 120; By the original contract generation unit 200, the original contract document generated in connection with the BIM drawing provided from the BIM drawing provision step (S100) is updated with the original contract document created in connection with the BIM drawing changed from the BIM drawing change step (S500). It is characterized in that it further includes a step (S600) of updating the original contract document or storing the original contract document in a different version in the original contract DB (250).

And in the original contract document updating step (S600), an electronic signature for the updated original contract document can be requested and obtained (S602). In addition, the primary contract document updating step (S600) can be processed so that electronic approval for the updated primary contract document is valid, and the electronic approval is processed to be valid, and the updated primary contract document can be stored in the primary contract DB 250 (S603) ). And in the step of updating the original contract document (S600), the original contract information posted on the web page may be modified with updated original contract information and posted again (S604).

Referring to Figure 9, in the original contract document updating step (S600), the BIM information in the updated BIM drawing is used by the original contract estimate generation unit 210 in the original contract generation unit 200 to update the estimate information for the construction work. A primary contract quotation update step (S610) in which the updated quotation information is used to update the previously created original contract quotation document, and the updated quotation information and the updated original contract information are used to update and update the detailed information on the construction work. It is characterized by including an original contract details update step (S620) in which the original contract details document is updated according to a preset original contract details format using the details information. In the original contract quotation update step (S610) and the original contract details update step (S620), the updated original contract quotation information and updated original contract quotation document are stored in the original contract quotation DB 260, and the updated original contract information and updated original contract details document are stored in the original contract quotation DB 260. It can be stored in the original contract details DB (270).

Therefore, the site management step (S400) of the present invention allows the construction start documents and construction daily reports that the site manager had prepared by hand or in a separate program to be prepared online. In the present invention, when a design change occurs in the field, the design change information is provided to the BIM drawing providing unit 100 and the contract generating unit 200, so that the BIM drawing provided from the BIM drawing providing step (S100) changes the design. Information can be reflected and updated, and original contract documents, original contract estimate documents, and original contract details documents created in connection with BIM drawings can also be immediately changed and updated to reflect the updated BIM drawings, making construction management more convenient for site managers. There is a significant effect that can improve .

③ Subcontracting between construction companies and subcontractors

Next, in the subcontract creation step (S700), a subcontract document containing the construction company information, subcontractor information, and subcontract information is created in connection with the BIM drawing by the subcontract creation unit 400, and an electronic payment method is used. Through this, subcontracting is processed effectively.

Referring to Figure 10, first, in the subcontract creation step (S700), subcontractor information can be requested and obtained from the subcontractor terminal 4 and stored in the subcontractor DB 410 (S701). And in the subcontract creation step (S700), construction company information stored in the construction company DB (240) can be requested and obtained from the public affairs department terminal (3) or the primary contract creation unit (200) (S702). And in the subcontract creation step (S700), subcontract information can be requested and obtained from at least one of the subcontractor terminal 4 and the public affairs department terminal 3, and the subcontract information can be stored in the subcontract DB 420. (S703).

When a draft document is created among subcontracting documents so that a subcontractor suitable for cost can be selected among a plurality of subcontractors, the subcontract creation step (S700) is performed by storing the information stored in the subcontract DB (420) in the plurality of subcontractor terminals (4). A breakdown form can be provided, and when each subcontract information is input from each subcontractor terminal 4 according to the above breakdown form, a quote comparison table can be generated (S704). The public details referred to in the present invention refer to details in which the unit and quantity for each item are prepared, but the cost for each item is not included. The subcontracting information may include costs for each item that can be provided by the subcontractor. In addition, in the subcontract creation step (S700), a quotation comparison table can be created in which the cost for each subcontractor's item is entered in a public statement form, and a draft including the quotation comparison table and each subcontractor's information can be created, It may be stored in the subcontract DB 420 (S705).

Therefore, the subcontract creation step (S700) of the present invention has a significant effect in that an automatically generated draft can be provided to the approval authority of the construction company and can help select a suitable subcontractor among a plurality of subcontractors.

In addition, for a subcontract with a selected subcontractor, referring to FIG. 11, the subcontract creation step (S700) includes construction company information, subcontractor information of the selected subcontractor, and A subcontract document can be created according to the subcontract form in which the subcontract information of the selected subcontractor is already stored, and the generated subcontract document can be stored in the subcontract DB 420 (S706, S707).

The subcontracting referred to in the present invention is a contract between a construction company and a subcontractor in which the construction company receives a construction contract from the building owner and then the construction company, the contractor, subcontracts the contract to a third party, a subcontractor, and the subcontractor completes part of the construction process. It refers to a contract that becomes effective when the construction company agrees to pay compensation for part of the construction process.

The above subcontractor information and construction company information include the name of the subcontractor/construction company, each business registration number, each company phone number, each company address, each company email, each fax number, each representative's name, each representative's resident number, and each representative's name. It can include date of birth, each representative's contact information, each representative's mobile phone, each representative's email, each representative's address, each representative, each representative's email, each representative's contact information, and each representative's mobile phone.

The above subcontracting information includes the type of work the subcontractor is responsible for, construction period, bid amount, supply price, labor cost, value-added tax, name of the primary contract construction work, name of the subcontract construction work, payment method, special provisions, contract conditions, defect warranty, materials to be paid, and quantity. , may include the contract date.

In the subcontract creation step (S700), an electronic signature for the subcontract document can be obtained from the public affairs department terminal 3, and an electronic signature for the subcontract document can be obtained from the selected subcontractor terminal 4 (S708 ). In addition, in the subcontract creation step (S700), the electronic approval generated online can be processed to be valid after all electronic signatures between contractors have been obtained, and in the subcontract creation step (S700), the subcontract document for which the electronic approval has been processed is valid. It can be stored in DB 420 (S709).

Meanwhile, in the subcontract creation step (S700), a subcontract is created with a subcontractor selected through bidding, so unlike contract creation, there is no need to generate an estimate.

Therefore, the subcontract creation step (S700) of the present invention allows subcontract documents to be created and approved electronically between the construction company and the selected subcontractor online, so that a contract can be concluded online, and subcontracts can be completed between contractors through mail and email. Work convenience can be improved by eliminating the need to exchange documents, and there is a significant effect of increasing the security and manageability of subcontract documents.

④ Subcontract/subcontract ready-made claims

Next, in the ready-made billing step (S800), when the subcontracted information is input from the subcontractor terminal 4 by the ready-made billing unit 500, subcontract settlement according to the subcontracted payment is performed, and the BIM drawing and field information are performed. Original contract information is created using .

Referring to Figure 12, first of all, in the subcontract ready-made claim between the construction company and the subcontractor, the ready-made claim step (S800) is the field wage, on-site meal, on-site conversion fee, on-site rebar/ready-mixed concrete status and information from the site manager terminal (2). It is characterized by including an initial ready-made step (S810) in which initial ready-made information including various execution details is acquired, and the initial ready-made information is used to generate an initial ready-made bill. The initial ready information and initial ready invoice can be stored in the initial ready DB (540) and the sales status DB (520).

The subcontracting claim referred to in the present invention refers to the settlement of funds used on site. Therefore, funds used on site may include the above-mentioned on-site wages, on-site meals, on-site deposits, on-site rebar/ready-mixed concrete status, and various execution details. At this time, it is most desirable that the initial ready-made bill (S810) is classified into each item and the initial ready-made bill is generated to facilitate the creation of a future settlement statement.

At this time, the subcontract DB 540 and the sales status DB 520 may store the initial ready information and the initial ready invoice. The reason why the initial ready-made bill is created before the subcontracted bill is created is to secure the subcontracted DB 540 to store the construction cost to be used in the future for construction work on an arbitrary building. In other words, the subcontract DB 540 can store not only the subcontract for any building, but also hundreds of subcontracts in progress by the construction company. At this time, in the initial construction stage (S810), the initial construction information is used to generate an initial construction invoice, so that the subcontractor DB (540) can store the initial construction information and the initial construction invoice for any building. Based on this, there is a significant effect of preventing errors that cause data confusion with other companies even when modifications and storage of items within the initial information are made.

In addition, in the ready-made claim step (S800), the subcontracted ready-made claim form stored in the subcontracted DB 540 can be provided to the selected subcontractor terminal 4, and when the subcontracted ready-made claim form is entered according to the subcontracted claim form, A subcontracting invoice may be created. The subcontract information and subcontract request can be stored in the subcontract DB 540 (S801, S802).

Referring to FIG. 13, in the ready-made request step (S800), the subcontract information, the subcontract information in the subcontract DB 420, and the original contract information in the original contract DB 250 are used and stored in the subcontract DB 540. A subcontract detail is created according to the subcontract details format, and the subcontract details can be stored in the subcontract DB 540 (S803, S804, S805).

In addition, in the ready-made request step (S800), an electronic signature for the subcontract statement is obtained from the public affairs department terminal 3, and an electronic signature for the subcontract statement can be obtained from the selected subcontractor terminal 4. (S806). In addition, the ready-made claim step (S800) can be processed so that the electronic approval generated online is valid after all electronic signatures between contractors are obtained, and the subcontract statement for which the electronic approval has been validated is stored in the sales status DB 520 and the subcontract status DB (520). It can be stored in DB 540 (S807).

The public affairs department terminal 3 can pay the subcontract bill according to the subcontractor information including the account information. Then, the public affairs department terminal 3 can generate settlement information for the paid subcontract bill. In the ready-made billing step (S800), a settlement statement can be generated according to the settlement form stored in the subcontracting DB (530) and stored in the subcontracting DB (540) (S808). And the ready-made billing step (S800) allows the settlement statement to be posted on the web page (S809).

Next, looking at FIG. 14, in the ready-made contract request between the building owner and the construction company, in the ready-made claim step (S800), the BIM drawing and site information are used by the ready-made claim unit 500 to generate original contract information. do.

The present invention is a ready-made BIM drawing generation step (S900) in which the original contract information is acquired from the ready-made billing unit 500 by the BIM drawing providing unit 100, and the original contract information is used to generate a ready-made BIM drawing. ) is characterized in that it further includes. And the ready-made BIM drawing can be provided from the ready-made billing unit 500 to the field manager terminal 2 and the public affairs department terminal 3, respectively.

Then, you can go through a three-step review process in the original contract request. First, the site manager terminal 2 can take on-site photos of parts to be prepared for any building at the site. Next, the public affairs department terminal 3 can review and confirm the part of the ready-made BIM drawing that corresponds to the site photo. Lastly, in the ready-made claim step (S800), based on artificial intelligence technology, the field photos taken from the field manager terminal (2) and the ready-made BIM drawings reviewed from the public affairs department terminal (3) can be compared, and from each terminal It can be confirmed whether it has been appropriately reviewed (S812).

The ready-made claim step (S800) is based on artificial intelligence technology, and if it is determined that it has been appropriately reviewed by each terminal, an original contracted claim can be generated according to the original contracted form stored in the original contracted DB (530) for the corresponding part. The original contract DB (530) can store site photos, comparison results of site photos and BIM drawings, and original contract invoices (S813).

Then, the building owner terminal 1 can receive the original contract payment request, and through the supplementation, modification, and approval process, the construction company's public affairs department can request the original contract payment from the building owner. When the original contract ready-made claim is paid according to the construction company information including account information from the building owner terminal (1), settlement information for the original contract ready-made claim is generated, and the ready-made claim step (S800) uses the settlement information. A settlement statement can be generated according to the settlement form and stored in the original contract DB (530) and sales status DB (520) (S814). In addition, the original contract amount may be reflected in the sales status DB 520. And the ready-made billing step (S800) can allow the settlement statement to be posted on the web page (S815).

Accordingly, the present invention performs subcontracting ready-made claims and subcontracting ready-made claims based on BIM drawings, enabling more objective and clear ready-made claims for each process of construction work and each part of the building, thereby enabling transparent construction cost processing. It works.

⑤ Repair of building defects

Next, in the defect repair step (S1000), the defect is received when the warranty information in the building warranty and the defect information of the building are obtained from the building owner terminal (1) by the defect repair unit (600), and the defect is received at the site manager terminal (2) When repair information on building defects is obtained from ), defect repair is effectively processed through electronic approval.

Referring to FIG. 15, first, in the defect repair step (S1000), a warranty for the building is generated and managed by the warranty management unit 610 in the defect repair unit 600 to facilitate maintenance even after the construction of the building is completed. It is characterized by including a warranty management step (S1100).

In addition, the defect repair step (S1000) is characterized in that the repair information and the BIM drawing are used to generate a defect repair report for buildings for which a warranty has been created so that the building owner can confirm the defect repair process. In other words, the field manager terminal 2 and the defect repair unit 600 can obtain ready-made BIM drawings from the BIM provider 100 (S1002). The site manager can generate repair information for building defects by inputting it through the site manager terminal (2).

Then, in the defect repair step (S1000), a defect repair report can be generated using ready-made BIM drawings and repair information, and stored in the defect repair DB 620 (S1003). In other words, building owners, construction companies, and site managers have the remarkable effect of being able to intuitively check which part of the building a defect occurred and check the defect repair process in detail by generating a defect repair report based on BIM drawings.

And for the defect repair report, in the defect repair step (S1000), an electronic signature for the defect repair report is obtained from the building owner terminal (1), and an electronic signature for the defect repair report is obtained from the construction company terminal (3). This can be obtained (S1004). In addition, in the defect repair step (S1000), after all electronic signatures between contractors are obtained, the electronic approval generated online can be processed to be valid, and the repair information, defect repair report before electronic approval, and defect repair for which the electronic approval has been validated are processed. The report may be stored in the defect repair DB 620 (S1005).

Therefore, the defect repair step (S1000) of the present invention allows a defect repair report to be generated and electronically approved online, enabling mutual confirmation of defect repair between the building owner and construction company online, and subcontracting by mail and email. Work convenience can be improved by eliminating the need to exchange documents, and there is a notable effect of improving the security and manageability of defect repair reports. In addition, the building owner can check and record the building's repair process and repair results online, and when additional defects occur in the building in the future, it is easy to determine whether the defect occurred due to the same problem or a new problem. There is a notable effect that can be discerned.
