Analysis and evaluation of growth in labor productivity in hydrotechnical construction using the index method

Under unsteady conditions in construction production and present-day scales of hydrotechnical construction, and in measuring and evaluating the rise in labor productivity by the generally accepted output factor, it is necessary to reduce the factor for the base (preceding) period to the level which is economically comparable with every planned or accounting year of a five-year plan.

The reduction of the base output factor to an economically comparable level is effected by a complex aggregated index with a fixed composition which takes into account the mutual interrelation and effect of individual indexes of the estimated prices, the calend ar budget of working time, proportional volumes of secondary items, outlay structure, and new techniques [Eqs. (1)–(8)].

The determination of individual indexes can be practically effected at the stages of planning and an analysis of the results obtained on the basis of the design-estimate documentation available to construction organizations, engineering-economic calculations on plans for new techniques, and current forms for statistical accounting (forms 2-SN, 2-C, journal-order 10-S, 3-PP, 3-T, 1 and 2-NT).

With an annual application of the index method, one achieves the exposure and elimination of unrealistic (unsoundly based) over- and underestimated evaluations of labor-productivity rises, and this permits a significant improvement in the analysis and planning of changes in the numbers of workmen and wages funds of construction organizations, viz.:

There is a considerable diminution in the interest of construction organizations in an economically unfounded increase in estimated costs and in expanding the supply of remotely located and high-cost materials;

contradictions between tasks set according to outlay growth and the introduction of more progressive, new construction techniques, are mitigated;

the effectiveness and efficiency of established limitations are raised in regard to the utilization of funds for material stimulation, depending on the tempo of the rise in labor productivity of construction organizations converted to the new planning methods.
