THE FUNDAMENTALS OF FORMING THE NUMERICAL COMPOSITION OF THE COMPLEX BRIGADE OF MASON-INSTALLERS

The design of the flow method of the construction of a multi-story residential building with stone walls and prefabricated reinforced concrete floor structures has its own features, namely, the presence of mechanized and non-mechanized (manual) processes, which implies a significant difference in the number of performers when coordinating flows among themselves. Taking into account the importance of ensuring the rhythmic execution of construction processes, the formation of the optimal numerical composition of the complex brigade is an urgent issue. 
As a result of the research, the complex process of building stone houses with prefabricated floors was divided into two streams: The first stream - assembly, transport and auxiliary processes: the first tier - delivery of pallets with bricks, delivery of boxes with construction mortar, monotonization of the gaps between the slabs; the second tier – installation of scaffolding, delivery of pallets with bricks, delivery of boxes with construction mortar, installation of the intermediate staircase and the first flight of stairs; the third tier – raising scaffolding, supplying pallets with bricks, supplying boxes with construction solution, dismantling scaffolding, installing floor slabs and the second flight of stairs; The second flow is the masonry of stone structures of the first, second and third tiers. 
As a result of the conducted research, the theoretical dependence of the numerical composition of the complex brigade on the volume of work on the fence, the norms of labor costs and the conditions of performance of the work were established. At the same time, the limitations of the minimum numerical composition of the link were taken into account, with the condition of its ability to perform the most complex process from the components of the flow, which determines the need for the largest number of performers. 
Also, restrictions on the maximum number of performers are taken into account, provided that each performer is provided with a sufficient front of work to perform it during the shift, and restrictions on the workload of performers depending on the accepted number of construction machines. The obtained results make it possible to optimize the technological design process.
