BEST MODE FOR CARRYING OUT THE INVENTION A unit price calculation device S according to the present invention is a device for calculating a unit price for construction of a building or the like.
FIG. 1 shows a hardware configuration of the unit price calculation device S of this example. As shown in the figure, the unit price calculation device S includes at least a reference price file 1, a reference walking file 2, a coefficient file 3, an input unit 10, an execution unit 20 for executing an operation, and an operation result. And an output unit 30.

The reference price file 1, reference walking file 2, and coefficient file are rewritable. Therefore, data can be updated at any time in response to price fluctuations, the appearance of new products, or the development of new work methods.

The reference price file 1 stores unit price data including standard material costs and labor costs. In the reference price file 1, the material costs are classified and stored by type, product number, and region, and the labor costs are classified by operation and region using public statistical data and the like. It is remembered. In addition to material and labor costs,
Machine losses and expense rates are stored as data.

The reference step file stores the steps for performing a predetermined operation for each type of operation. The gait registered in the standard gait file is determined and adopted as the standard gait as follows.

First, information on walking steps for each work is collected from the conventional construction examples. At this point, the walking steps have different numerical values due to the different construction conditions. Therefore, these steps are classified according to construction conditions.

First, walkers are classified according to the first construction conditions. If the steps still vary even after being classified according to the first construction conditions, the steps are further classified according to the second construction conditions. In this way, the steps are classified according to the construction conditions. The average value of these classified steps is taken and adopted as a standard step for each construction condition. These reference prices and reference steps are used as base values when calculating the construction unit price.

The coefficient file 3 stores a coefficient for reflecting the construction conditions more finely on the basis of the reference price and the reference step, based on the reference price and the reference step. That is, it is not possible to obtain a construction unit price that reflects all construction conditions only with the reference price and the standard walking rate. Therefore, this coefficient reflects differences in various construction conditions in the construction unit price.

For example, it is assumed that, for a certain material, the reference price file stores the material price for each model number. Further, each coefficient is selected to represent a difference in price due to the thickness of the material, a price of an auxiliary material that varies depending on the thickness of the material, a difference in labor due to a work environment in which the material is used, and the like. .

As another example, the excavation work will be described. The work scale, excavation depth, soil quality, construction method, work environment, and the like are further reflected on the reference walk of the excavation work selected from the reference walk file. Is multiplied by In addition, for example, when a standard step for an excavation work has a standard step for each scale, the selected standard step is used to further determine the digging depth, soil, construction method, and work environment as other construction conditions. The coefficient for reflection is multiplied.

In this way, the detailed construction conditions are reflected on the construction unit price. The above-mentioned coefficients are set as 1 for the most standard construction conditions, and each coefficient is determined by comparison with the standard construction conditions. The coefficient may be, for example, a comparison of the time required for the operation,
It is determined by comparing the amount of work that can be processed at a time.

The input of various construction conditions is performed by the input unit 10.

As described above, when various construction conditions are input, the execution unit 20 calculates a reference price file 1, a standard walking file 2, and a coefficient file 3 based on the construction conditions.
Select predetermined data.

The execution unit 20 calculates the construction unit price based on the selected reference price, reference step, and coefficient. More specifically, the construction unit price is calculated from a combination of various elements as shown in FIG.

FIG. 3 shows a method of calculating the construction unit price when the foundation formwork is installed, and the construction unit price (formation cost).
Is composed of components such as a mold cost as a material cost, an assembling cost and a disassembly cost as a labor cost, and a form transportation cost as a loss cost.

The above costs are further composed of a plurality of factors, and each of these costs reflects the construction conditions. Then, the final construction unit price is calculated by integrating the calculation results of these costs.

It should be noted that the unit price calculating device S of the present embodiment allows the user to fine-tune each cost, walking, etc., according to the individual circumstances of each user or the sudden change in the social situation.

The survey file 5 is provided in the
After the construction is completed, it is preferable to input actual walking steps and the like and accumulate the information at any time. In other words, by accumulating information on actual actual walking as the actual value, the information is reflected in the standard price file, the standard walking file, and the coefficient file to further improve the accuracy of the calculated construction unit price. Becomes possible.

By outputting the survey file 5 from a communication control unit or the like, information can be accumulated in one place, and information can be analyzed more efficiently.
