DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction budget formulation method and a construction budget formulation system which uses a computer to select and appoint a contractor for temporary work including temporary work including paintwork, repair work and scaffolding. For details, use the computer communication to release, present or send out the accumulated data of the company relating to the construction property to at least a specific group of contractors outside the company, and unify the basic data (construction By soliciting construction estimates based on property standardization information) and evaluating the application quotes by index based on certain assessment standards, the budget for the construction was promoted appropriately or rationally and reflected in decision-making. The present invention relates to a construction budget formulation method and a construction budget formulation system.

[0002] Conventionally, an estimate (specifically, a budget formulation) for a construction property represented by painting, repair, or temporary construction is:
In a series of work processes starting from the installation of a temporary stand, it takes a great deal of time and effort to start from the estimation based on drawing creation and to optimize the estimated cost.

[0003] Under these circumstances, several proposals regarding rationalization of estimation creation are known.

(1) There is known a system for estimating necessary materials, man-made work (garlic), construction period, and the like from detailed drawings created by CAD, and estimating a total budget for construction. Here, it is premised that CAD drawings are created, and there is a case where the labor cannot be ignored.

(2) On the other hand, the applicant of the present invention does not need drawings for temporary scaffolding work, stores past results (values) in a data file, and sets some construction conditions. An integration system that enables integration processing based on the quantity of materials is proposed. [Japanese Patent Application No. 9-32695
No. 7; hereinafter, the prior application system. )

However, development of an extended system (a construction budget formulation system according to the present invention) capable of computer-assisting cooperation of ordering with an external contractor for materials and construction by utilizing the result of the multiplication system has been developed. Was on the way.

(3) Further, as a system capable of integrating a construction cost close to the final contract estimate without a drawing, there is a proposal to estimate from various influence factors using statistical theoretical values. [For example, see JP-A-6-110903.
issue. ]

However, it is not possible to flexibly cope with a study item (accumulation factor) which differs depending on the construction price level at the time of creation and each construction property.

(4) Further, in order to purchase desired materials at an appropriate price and to obtain an optimal estimate, a competitive bidding (phase estimate) between external contractors is performed via a communication network to streamline business procedures up to a contract. There are suggestions to try. [For example,
JP-A-11-39389. ]

However, from the viewpoint of ensuring the construction quality, it is not possible to determine the delivery / construction company only by focusing on the price level, and it is necessary to standardize the contents of the cost evaluation (assessment criteria). Will be

[0011]

[Problems to be Solved by the Invention] Generally, the problem that the decision of the contractor concerning this kind of construction property is uncertain involves the confusion of the value system due to rigging and dumping, and the series of contracts such as prime contractor and subcontractor. I cannot deny criticism that it has had an adverse effect on rationalization (structural reform) of various business formats.

[0012] The present invention has been made in view of such circumstances, and solves the above-mentioned problems, and calculates an optimal construction budget that is fair, belongs to the current construction price level, and can be used for the construction. It is intended to provide a construction budget formulation method and a construction budget formulation system which appropriately or rationally promotes such budget formulation and reflects it in decision making.
