Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction management system for fairly and smoothly managing construction work using the Internet in order to prevent troubles caused by construction work of various buildings including ordinary houses. .

[0002]

2. Description of the Related Art In the construction of a general house, a contractor who has signed a contract with the owner performs construction work based on the drawing for which confirmation has been applied. In general, a specialized contractor corresponding to the type of construction, such as an exterior, is in charge of the construction, and only the construction is managed by the contractor.

[0003] During construction, inspections after construction are usually not performed except when a public loan, such as a public finance corporation, is received. Only about one test is performed during the test.

[0004]

In the case of a general house constructed with such a system, problems such as cracks, rain leaks, and inclination of the building often occur after delivery to the owner. If these troubles occur after delivery, trouble often occurs between the owner and the contractor over the responsibility.

[0005] That is, the cause of the malfunction may be force majeure, but in many cases it is a construction defect called a hand-cutting construction. If the management during the construction work is adequately performed, the responsibility will be clarified, and above all, the frequency of failure itself will be greatly reduced. The reality is that they are not well managed and are left to contractors. Due to inadequate management during construction, construction failures are overlooked, which leads to failures after delivery and furthermore to troubles between the owner and the contractor.

[0006] The occurrence of troubles after the delivery and the troubles resulting therefrom cause not only a great financial burden and a mental burden on the owner, but also a great credit problem for the contractor.

[0007] An object of the present invention is to provide a building construction management system in which a third party manages construction work fairly and smoothly using the Internet, thereby improving the convenience of both the owner and the contractor. .

[0008]

Means for Solving the Problems In order to achieve the above object, a construction work management system of the present invention is owned by a management contractor who has received a request for construction work management from a client or a contractor,
And a host computer that can be connected to the computer owned by the client and the Internet, and a portable information terminal that is owned by the management company and that can be connected to the host computer and the Internet. Using the information exchange, the management company performs construction management on behalf of the client and reports to the client.

[0009] With this, detailed site information is given to the client, and the construction defect is eliminated, thereby preventing the occurrence of trouble after delivery and the trouble associated therewith.

The manager can transmit information obtained at the construction site from the portable information terminal to the host computer, and can centrally perform construction management based on the transmitted site information. Thereby, construction management can be performed more efficiently.

[0011] The management company, as part of the construction management,
Find construction defects based on information obtained at the construction site,
Correction of the defect can be instructed to the contractor. Thereby, construction management can be made more effective.

[0012] For the site information, a high information value can be obtained by including a check sheet and a photograph.

The management company manages the building following the construction management. As a result, it is possible to more effectively prevent troubles due to occurrence of trouble after delivery.

[0014] The management company can carry out the construction management step by step for foundation work, frame work, exterior work, and interior work. Thereby, more precise construction management can be performed.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a building construction management system according to an embodiment of the present invention, FIG. 2 is a flowchart showing a work flow in the system, and FIG. 3 is an explanatory diagram of a check sheet used in the system.

As shown in FIG. 1, the building construction management system according to the present embodiment, when a construction company B builds a general house in response to a request from a construction company A, either of the construction company A or the construction company B, Is also an independent third-party management company C
However, upon receiving a request from the owner A, the building work is managed.

For this management, the management company C has a host computer 10 at its head office. In addition, the employee has a plurality of portable information terminals 20, 20 carried by employees. The host computer 10 includes a portable information terminal 20,
20 and the Internet. Also,
Personal computer 30 owned by client A (hereinafter referred to as personal computer 30)
Internet connection is also possible with the owner computer 30) and the personal computer 40 (hereinafter, referred to as the installer computer 40) owned by the installer B.

The management company C fairly and rationally performs the management work of the construction work by utilizing information exchange between these computers via the Internet. The contents of the work will be described with reference to FIG.

Prior to signing a construction contract with the contractor B, the owner A signs a building construction management contract with the manager C. This contract can be made between the host computer 10 and the host computer 30 via the Internet. Based on this contract, the management company C first participates in the construction contract signed by the owner A with the construction company B, and checks the contents of the contract. If there is a problem with the contract contents, the coordination between the owner A and the contractor B will be attempted.

Based on the contract with the owner A, the contractor B prepares a construction work schedule and starts construction work.

The management company C checks the created process chart, and dispatches an employee to the construction site during the period of the foundation work based on the process chart to check the foundation work. The employee brings the portable information terminal 20. The portable information terminal 20 is, for example, a notebook personal computer, and has a check sheet as shown in FIG. 3 as data.

The employee dispatched to the construction site checks the items described in the check sheet and transmits the result to the host computer 10 at the head office via the Internet. In addition, the construction site is photographed with a digital camera, attached to a check sheet, and attached to the portable information terminal 20.
To the host computer 10.

The check items of the foundation work include the observation of the topography and soil quality of the site, the compaction state of the soil after excavation, the confirmation of the diameter of the foundation reinforcement, the confirmation of the number of foundation reinforcements. Confirmation, confirmation of surface condition of foundation concrete ... confirmation of anchor bolt diameter, confirmation of number and position of anchor bolts, etc.

At the head office, the management technician finally determines whether or not there is a problem in the foundation work based on the check result of the foundation work transmitted from the portable information terminal 20 to the host computer 10 and the photograph of the site. If no trouble is found, the result is notified from the host computer 10 to the client computer 30 via the Internet.

If a defect is found, the contractor B is instructed to correct the problem after consulting with the contractor B based on the check sheet and the photograph.
This instruction is also performed by transmitting information from the host computer 10 to the installer computer 40 using the Internet. Receiving this instruction, the contractor B corrects the place where there is a defect, and notifies the manager C of the completion. This completion notification is also performed by transmitting information from the installer computer 40 to the host computer 10 using the Internet.

Upon receiving the notice of the completion of the rework, the management company C sends the employee to the construction site again. The employee re-checks the place where the defect was found, attaches a photograph if necessary, and transmits the result of the re-check from the portable information terminal 20 to the host computer 10 at the head office. At the head office, the final check confirms that the problem has been resolved. If the problem has not been solved, a correction instruction is issued to the contractor B again.

The client A, who is the client, is notified that there is no problem in the foundation work by transmitting information from the host computer 10 to the installer computer 40 using the Internet. If there is any corrective work for the defect, we will also report that fact. When the trouble is solved, the fact is written on a check sheet in the host computer 10 and the trouble is also written on the check sheet in the portable information terminal 20 through the Internet.

Hereinafter, the construction, exterior construction, and interior construction are managed in the same manner using the Internet.
The result is reported to Owner A. In addition, the contractor B is instructed to correct the defect as necessary.

When the entire construction is completed, the property is delivered from the contractor B to the owner A. The management company C makes the photograph taken during the construction period into a CDROM and gives it to the owner A with a construction check sheet, and the management contract for the construction work ends.

After the completion of the construction work, the owner A can exchange a building management contract with the construction manager C as an optional contract. If a building management contract is signed between the two, the construction manager C checks the building once a year during the contract year, for example, 10 years.

If a defect is found as a result of the check, it is determined whether the defect is within the responsibility of the contractor B or due to aging. If the problem is caused by the contractor B, the contractor B is contacted and guidance is given to correct it. If the failure is due to aging or is within the responsibility of Owner A, consult with Owner A to confirm the corrective method, obtain an estimate from the contractor, confirm the contents, and confirm Report to

According to such a building management system using the Internet, the construction work of a general house is managed precisely and fairly by the management company C which is a third party independent of both the owner A and the construction company B. Is done. For this reason, there is no need for overwork or construction errors, and after delivery, inconveniences such as cracks, rain leaks, and inclinations due to these construction defects are eliminated.

Although the general owner A is not familiar with the construction, he can nevertheless obtain abundant specialized construction data, and can use the data effectively to eliminate construction defects.

Even if an inconvenience occurs after the delivery, since the detailed management data during the construction period is stored, the responsibility is clarified, and the unnecessary relationship between the owner A and the contractor B becomes unnecessary. Trouble is avoided.

The client A needs to pay a management fee to the management company C. However, the management cost is kept low by using the Internet for the management, and a building without omission is obtained by the precise management. Considering that subsequent unnecessary troubles can be avoided, the satisfaction with the management cost is extremely large.

In particular, when a building management contract is made between the owner A and the management company C, the mental burden of the owner A is further reduced.

In the management of building work, a huge amount of data such as detailed check sheets and photographs is quickly exchanged between computers by using the Internet. As a result, the presence or absence of a defect is collectively and accurately and promptly determined in the head office. As a result, the management cost is reduced, and the economic burden on the client A, the client, is reduced. In addition, unnecessary delays in construction due to management intervention are avoided.

The above embodiment shows the case where the owner A requests the management company C for the construction management, but the construction company B can also request the management company C for the management of the construction. As described above, at present, the contractor B itself cannot sufficiently manage the construction work, and entrusting this to the contractor C to improve the construction quality includes improving the contractor's credibility, including improving the trust of the contractor B. B also has a great merit.

In the above-described embodiment, a general house is taken as a building. However, the present invention can be applied to offices, buildings, and the like, and the structure of the building is not limited to wooden, RC, and S structures. However, poor construction is particularly common in wooden general houses with many connections, and from this point, the present invention is particularly effective for wooden general houses.

[0040]

As described above, the construction work management system of the present invention eliminates construction defects by allowing a third party to manage construction works fairly and smoothly using the Internet, and eliminates defects after delivery. This has the effect of preventing the occurrence of troubles and the troubles associated therewith, and bringing great benefits not only to the owner but also to the contractor.
