Prediction of major building repair duration as a function of workforce size

Introduction. The primary tool for planning labour intensity, duration and cost of construction and repair works are documents of technological regulation. The evidence base of these documents is grounded in statistical processing of a large number of experimental field measurements of these parameters on the construction site, as well as cost calculations considering price fluctuations under market conditions, along with generalization of practical experience from construction organizations.

Materials and methods. In carrying out a set of construction or repair-construction works, an important organizational decision in practice involves substantiation and selection of work sequence, possible overlap in time and space determined by technological requirements. Typically, execution of such works is carried out by a team of workers representing different professions and qualifications, where more complex and critical technological operations are performed by highly skilled workers.

Results. To ensure proper quality of work and efficient use of working hours when performing individual types of repair-construction works, regulatory documents stipulate minimum staffing levels and qualification standards. When organizing work using flow methods to maintain rhythm, the number of personnel may be increased depending on specific volumes of particular tasks and accepted sizes of sections and areas.

Conclusions. For simplifying the procedure of making decisions regarding provision of human resources for a package of capital repair works given specified volumes and durations, a graphic interpretation tool has been developed. This tool helps form rational quantitative and qualitative composition of workers engaged in various activities within integrated teams.
