On the issue of improving the accuracy of construction cost calculations at the pre-project stage

Abstract

The article deals with the issues of determining the cost of construction products on the territory of the RF at the pre-project stage. The results of the obtained calculations of the construction cost at the pre-project stage are analyzed using various methods. The disadvantages of determining the cost of construction using the enlarged collections of the CPS-2020 are revealed. Ways to improve the accuracy of construction cost calculations at the pre-project stage are proposed, in particular, by applying extrapolation formulas that are currently not available in the methodology for calculating construction costs based on enlarged collections. It is proved that the application of the proposed formulas significantly increases the accuracy of calculations, bringing the obtained values closer to the most accurate calculation of the construction cost – the result of the consolidated estimated calculation of the construction cost, compiled within the project documentation.
