Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a real estate management method for managing real estate such as land and buildings.
The present invention relates to a real estate management method and a real estate management system that are effective for centrally managing a plurality of real estates as assets distributed in regions.

[0002]

2. Description of the Related Art In the case of a large company or a large organization, a large number of real estate properties such as buildings and land are held as assets throughout the country, and the building is rented to a third party for operation. I have. Since this large number of real estate properties scattered throughout the country cannot be managed by the general management department alone, branch offices (including related companies) are set up in each area unit and properties in the area corresponding to each branch office are directly managed. In the general management department, only financial management is performed.

[0003] Each branch office has a contract with a (building) management company to manage the hardware such as cleaning, inspection, facility management, etc. of the building in the management area, and also contracts with the tenant of each building. Of the property. For example, each branch office manages leases such as renting to B only an area of 40 m ² of the fourth floor of building A.

[0004] If there is a request for leasing as described above from a third party, the branch office refers to a paper real estate ledger or a paper drawing,
Furthermore, after actually going to the target building and checking the availability of vacant rooms, a lease contract was made, and the lease contract was sent to the general management department for approval. Due to the necessity of financial management, the general management department receives and manages only lease contract information as financial accounting information from each branch office as described above.

[0005]

At the branch office, information such as rentals in the building is managed in a paper real estate ledger for each contract, so information on the corresponding real estate property (tenant status Access) is cumbersome. Also, the drawings (plans, equipment drawings, etc.) describing the actual renting location etc. are drawings that are manually added to the design drawings at the time of building the building, so the drawings are The drawing information became inaccurate as the renewal was repeated due to the change of the lessee or the floor plan. Therefore, the drawings are only for reference, and it is necessary to actually go to the building to check the current situation.

[0006] In order to accurately update each drawing, a sufficient understanding of the architecture is required, and it is uneconomical to assign a group having such knowledge to all of the branch offices. Not realistic in point. Also, from the point of view of the general management department, lease contract information is conventionally received from each branch office as financial accounting information, so financial accounting information is continuously managed according to certain standards. It is not possible to grasp information on real estate physical quantity information (use status, etc.) and qualitative information (how much the building is OA, etc.), such as which rooms in which buildings have vacancies and how much. Was.

[0007] Here, the entity of the asset cannot always be measured and displayed only by monetary value, but the status and status of the tenant occupying the building, the status of maintenance, the status of OA, and the area of each floor. The value of an asset also differs depending on the situation. However, in the general management department,
At present, it is not possible to grasp not only the usage status and performance of properties nationwide as described above, but also to accurately grasp even at each branch office.

In the case where only one building (real estate) is managed by one company, the above-mentioned problem may not occur easily. However, it is usually difficult to manage a plurality of real estates by one branch office. However, as the size of the real estate increases, the above-mentioned problem increases. Also, even if only one property is to be digitized in order to associate information necessary for real estate management, in addition to computer hardware and software, construction engineers (first-class architects), CAD
The need for an expert group of operators, computer technicians, accountants, etc., will result in management costs far beyond practical levels.

The display can be switched between the display units 2 and 13 and the drawing data 14.

The terminal 4 of the supervisory section is connected to the network system of the support organization 19 via the Internet 2 and the terminal 4 of the supervisory section and the support organization 19 are connected.
It is possible to send and receive information to and from terminals. In addition,
The support organization 19 includes construction engineers (first-class architects), CAD
Experts, such as operators, computer technicians, and accountants, work as needed.

The network system of the support organization 19 is as follows:
It has a configuration similar to that of the network of the general management section 1, is connected to the Internet 2 via a router 27, and has a terminal 4 (client PC) of the general management section via a bus 28 connected to the router 27. A web server 25 and a database server 26 are connected.
As a result, the terminal 24 of the support organization is connected to the terminal 4 of the supervisory department, and the database server 26
, Each database 20, 21 of the support organization 19 managed by the database server 26 is accessible.

Here, each database 2 of the support organization 19
The data in 0 and 21 stores the same data as the drawing database 10 and the ledger database 11 of the general management section 1. In addition, the support organization 19 is connected to the general management section 1 of a plurality of companies and organizations via the Internet 2 and can simultaneously support a plurality of companies and organizations.

In the above configuration, when a tenant negotiates in each branch office, a request for reference is transmitted from the terminal 3 of the branch office to the web server 5 of the general control department 1, and the web server 5 of the general control department 1 When it is recognized that the terminal is permitted to be referred to and the user who can refer (confirmed by a password or the like), a property list menu as shown in FIG. Note that the range of the list that can be displayed in each branch office may be limited.

Next, at the branch office, when a property whose details are to be examined is selected from the property list menu and the property details button is selected, the selected information is transmitted to the server of the general management section 1 and the corresponding attribute data 12 , 13 are input from the database server 6 and edited, and a predetermined menu screen is transmitted to the terminal 3 of the branch office. As shown in FIG. 5, the detailed property information is displayed on the terminal 3 of the branch office in a predetermined menu format. In addition,
Similarly to the above, the range of information transmitted to the terminal 3 of the branch office may be limited. Further, as needed, room information (such as usage status) of each floor unit of the building may be received from the web server 5 of the supervising management section 1 and displayed. Then, if necessary, the details of the displayed property are printed. It is also possible to display in an Excel format as shown in FIG.

The branch office displays and prints the details of the property corresponding to the ledger of the property, and selects the drawing display on any of the menu screens (see FIGS. 4 and 5). The drawing list transmitted to the server 5 of the general management section 1 and corresponding to the selected information is stored in the terminal 3 of the branch office.
And a drawing list menu as shown in FIG. 7 is displayed on the terminal 3 of the branch office. When a plan view of a target floor is selected from the drawing list, for example, a corresponding plan view as shown in FIG. 8 is displayed on the terminal 3 of the branch office, and the plan view is printed. Note that the above printing is not always necessary.

Further, in the branch office, FIG.
The tenant position, shape, size, etc. are written as shown in FIG. 10 and the data of the contract document as shown in FIG. 10 is created. It should be noted that a predetermined menu screen is prepared in advance also for the data of the contract document so that it can be easily entered. Subsequently, the written drawing data and contract document data are transmitted to the server 5 of the supervisory department 1 via the Internet 2. In this embodiment, as shown in FIG. 10, the file name of the drawing data is entered in the menu of the contract document, and the menu of the contract document is transmitted, so that the drawing data is also transmitted to the web server 5 of the integrated management section 1. I try to send.

The transmission may be made to the general management section 1 by a communication means such as a facsimile without using the Internet 2. Thus, at the branch office,
Accurate and up-to-date drawings and property status are readily available,
It is possible to check the availability and the state of the property without actually looking at the property. It also makes it easier to make plans for building maintenance and the like.

The supervising management section 1 checks the drawings and contract documents transmitted from the terminal 3 of the branch office as real estate information and makes a decision on the lease contract. All or a part of the data of the contract is transmitted to the support organization 19. The transmission may be performed via the Internet 2 or a transmission means such as a facsimile may be used.

In the support organization 19, the data of the data in the databases 20 and 21 of the support organization 19 are displayed on the computer screen of the terminal 24 in the same manner as the data operation at the branch office.
The CAD drawing data 14 that needs to be changed is searched and displayed, and the drawing data 14 is updated based on the real estate information transmitted from the general management section 1. The change for this update is performed by referring not only to the drawing data 14 but also to text data (such as contract contents).

Next, the attribute data 12 and 13 corresponding to the CAD drawing data 14 are called on the computer screen of the terminal 24, and the contents of the data are updated. In the case where the real estate information transmitted from the general management section 1 is newly managed, the corresponding CAD drawing data 14 and attribute data 12 and 13 are obtained from the acquired real estate information.
Are created individually, and chain data connecting the created CAD drawing data 14 and attribute data 12 and 13 is added to the table. Unnecessary data is deleted as needed.

The updating of the database may be performed every day, or may be performed once a month. The support organization 19 may send the update data to the general management section 1 via the Internet 2 or copy the data to a recording medium such as an MO and mail, deliver, and bring the recording medium to the general management section 1. May be sent to

The central management section 1 updates the databases 10 and 11 of the central management section 1 with the update data obtained from the support organization 19. In the case where the databases 10 and 11 of the supervisory department 1 are constructed to be accessible directly from the support organization 19, the databases 10 and 11 of the supervisory department 1 may be updated directly from the terminal 24 of the support organization. .

In this embodiment, the attribute data 12, 1
Although there are two types of 3, any number of menus displayed on each terminal using the attribute data 12 and 13 can be stored in the web servers 5 and 25 according to the contents to be displayed (edited). For example, as shown in FIG.
A menu display for each management block may be prepared.

By constructing the system having the above-described configuration, the supervising management unit 1 can provide real estate information such as physical and usage status other than the financial accounting information to the real estate properties dispersed in various places. Can be managed centrally.
As a result, for example, what kind of distribution a certain tenant makes a lease contract with our company nationwide, and a tenant contract spanning a plurality of areas can be easily implemented.

That is, not only can information on real estate distributed throughout the country be accurately grasped, but also necessary property information can be quickly obtained. For this reason, since the real estate is all grasped as an asset by the general management section 1 and desired statistical information can be obtained, it is possible to evaluate all real estate as an asset. In addition, since the centralized management department 1 centrally manages the data, it is necessary to maintain accurate and prompt data even at branch offices, although the maintenance work on the materials to be held individually and the management materials at each branch office is reduced. Property materials are available,
The efficiency of sales activities such as contracts can be improved. In addition, since accurate and up-to-date equipment drawings of each building are available,
Even a building management company can easily perform a building maintenance plan and the like. In addition, the centralized management by the general management section 1 makes it easy to integrate or relocate branch offices.

Even if the branch office, which is the site, is a consignment company and is not a subsidiary of the general management unit 1, since the central management unit 1 centrally manages information, the branch office, which is the site, The property information that can be referenced by the company can be controlled by the general management section 1. That is, information that can be referred to can be controlled in accordance with the creditworthiness of the branch office. Also,
In the present embodiment, since the database 10 of the drawing data 14 and the database 11 of the attribute data 12 and 13 are separate databases, it is possible to individually create and update the drawing data 14 and the attribute data 12 and 13 respectively. It becomes possible. For example, a CAD drawing of a building is created individually by a plurality of contractors and is often integrated into a single drawing information database.
If the same database is used for the drawing data 2 and 13 and the drawing data 14, the registration work and the update work may be troublesome.

Here, the terminal 3 of the branch office is not limited to a stand-alone type terminal installed in the branch office, but may be a portable type terminal. Also, although a building is mainly described as real estate, it may be land. In addition, although the update of the data in the database is requested to the support organization 19, the update work of the data may be performed in the general management section 1. However, the creation and modification of architectural CAD drawings require specialty, and it is necessary to have a dedicated group for that purpose in the general management section 1 at all times.

In this regard, the support organization 19, which is a group of experts,
In this case, each database can be updated accurately and efficiently, and the database for the property information is stored in two places. Further, when a large number of companies request the support organization 19 to register and update a large number of individual real estate managements, the support organization 19 becomes a member of a construction engineer (first-class architect), a CAD operator, a computer engineer, and an accountant. Since the amount of work required to have at least one proficient person or the like can be resident each time, the equipment and specialists can be effectively used, and the management cost per property can be reduced. There is a significance.

[0044]

As described above, when the real estate management method and real estate management system of the present invention are adopted, information on distributed real estate can be centralized at one place, and can be managed accurately and at low cost. . As a result, the entity of the real estate as an asset can be accurately grasped.

In the case where the information of the real estate is managed by the general management department, not only the real estate information to be held at the branch office at the site is reduced, but also accurate real estate information is always obtained from the general management department. It becomes possible.
