In particular, regarding the cost, "planned unit price" x
It is calculated by "quantity" calculation.

Here, the elements to be recorded as "quantity" include, for example, "type and number of workers", "amount of wear on each construction machine", "fuel cost of each machine", and "amount of each material". is there.

In public works ordered by government offices, in order to eliminate the discrepancy between the cumulative amount of government offices and the "quantity" at the actual construction site, and to recognize the discrepancy, manual construction at a typical construction site is carried out. An investigation is being conducted.

[0006]

However, since such a construction site survey method is a sampling survey only on a typical construction site, the accumulated amount of government offices and the actual construction contents at each construction site are compared. There may be a gap between them.

As a result, the transparency of the planned price becomes unclear, and there is a possibility that an excessive summation will be performed.

Further, since the on-site inspection at the construction site is carried out manually, the inspection accuracy may be a problem.

The moving distance of itself or the moving part of the construction machine or each worker is specified, corrected by the correction value transmitted from the base station 1, and the fuel per unit moving distance is added to the corrected movement distance of the construction machine. It is converted into fuel consumption by multiplying the consumption. Further, the collection / comparison server 4 is required to generate the amount of electricity used per unit moving distance and the total amount of rotating torque of the generator necessary for generating the amount of electricity used, in the moving distance of the movable part of the construction machine. It is converted into fuel cost by multiplying it by a conversion coefficient that converts it into different fuel consumption.

The travel distance of the machine itself or the movable part of the construction machine or each worker is specified, and the specified travel distance of the construction machine is multiplied by the fuel usage amount per unit travel distance to be converted into the fuel usage amount. In addition, the data collection processing server 12 generates the amount of electricity used per unit moving distance and the total amount of rotation torque of the generator required to generate the amount of electricity used, in the moving distance of the movable part of the construction machine. It is converted into fuel cost by multiplying it by the conversion factor that converts it into the required fuel consumption. Further, the data collection processing server 12 calculates the allocation rate from the moving distance of each worker and multiplies the budget total by the allocation rate to calculate the labor cost of each worker. Then, the data collection processing server 12 sums the fuel cost and the labor cost, calculates the total cost by summing the fuel cost, the labor cost, and the material cost whose description is omitted, and transmits the total cost to the data comparison processing server 13. .

Then, the data comparison processing server 13 calculates the difference between the calculated total cost and the integration standard, and compares the calculated difference with a predetermined difference.

As a result, there is no need to manually conduct a survey on the construction site, the labor required for the survey on the construction site is reduced, the survey accuracy is improved, the transparency of the planned price is secured, and the overestimation is overestimated. Can be prevented.
