Labor productivity (or complexity) is measured: in calculations of the efficiency of mechanization and automation – labor costs – in man -to -one per unit or on the entire range of works performed by a mechanized way. At the same time, workers who are directly involved in maintenance of machines and mechanisms are taken into account, auxiliary workers, as well as workers who carry out the current repair, installation and dismantling of machines and the necessary devices, such as crane tracks; When calculating the effectiveness of new designs, materials and new technological processes – labor costs for the construction of structural elements (in people. days not given to the 1st category), or on the basis of production (in monetary terms) per 1 person. day. Labor costs for the manufacture of structures, parts and materials in this case are not taken into account, they are taken into account when determining the effectiveness of their production in the industry of building materials; when calculating the effectiveness of projects for the construction of facilities – the average annual number of employees in construction; With complex calculations on a scale of the economic region or the Union Republic – the average annual production (in monetary terms) for one working.
Example. In the Economic area for the seven years, it is planned to increase labor productivity in construction by 75% with an increase in average wages by 45%. The share of the main wage in the basic cost of construction and installation works was 22%.
Reducing cost due to growth in labor productivity will be.
In excess of this, a decrease in the amount of overhead costs depending on the number of workers and on the total size of the wage fund.
During the construction in non-combined areas, the growth of labor productivity increases to a decrease in the costs of initial development-an organized set of workers, improvement, housing and communal construction construction. When comparing options, this factor must also be taken into account along with a decrease in one -time costs associated with the introduction of new technology.
Definition of the economic effect. The annual economic effect obtained as a result of the introduction of new technology in general form is determined by the formula where changes in the cost (C) and capital investments (K) associated with the use of new equipment are taken in case of decrease with the plus sign, and with an increase with the sign with a sign minus.
