Abstract
Economic indicators of construction production are directly related to the choice of the optimal number of machines. The lack of machines for the production of construction and installation works leads to the impossibility of their implementation in the directive period. The pace of construction and installation work and labor productivity depend, to a large extent, on the degree of provision of construction facilities with machines (level of labor mechanization). The article considers the calculations of the need for construction machines for the building site, trust and the ministry. When determining the need for machines for construction sites, it is necessary to take into account ensuring the execution of works in the planned timeframe, increasing the level of complex mechanization, increasing labor productivity and reducing manual work, improving the use of the machine park and their operation. The article presents a consistent set of formulas that must be used when choosing construction machines and determining their number.

Lack or excess of machines for the production of construction and installation works in construction organizations significantly affects the economic performance of their operation
In determining the need for machines for construction should be considered: - Ensuring the implementation of work on the objects in accordance with the planned deadlines; - increasing the level of complex mechanization for construction and installation works; - increasing labor productivity and reducing the share of manual labor; - the use of progressive work methods; - improving the use of the existing engineer fleet; - ensuring the required rate of the engineer fleet renewal
Summary
Lack or excess of machines for the production of construction and installation works (construction and installation works) in construction organizations significantly affects the economic performance of their operation. Determining the need for cars at different levels of park formation has its own characteristics both in the methodological approach and in the specific expression, i.e. the need for a unit of work (pcs., m3, m2, etc.), for 1 million rubles’ construction and installation works (CIW) This takes into account the specificity of the fleet’s functioning and purpose (the fleet for the building site, the fleet of the trust or the fleet of the ministry). If for machines used with one type of work equipment, as a rule, the operating conditions at various facilities cannot differ in a large number of technological factors, for universal construction machines having several types of replaceable work equipment, the number of technological factors affecting its performance use, expressed in the result of development during the stay at the building site, can be much more [2] This can be shown by the example of a single single-bucket universal excavator.
