Expeditionary method of building objects by mobile units.

With a significant distance of objects under construction from the places of deployment of construction enterprises, construction is carried out either on a rotational or expeditionary basis.

In the expeditionary mode, construction is carried out by mobile units, which are sent to the work site, usually for one season or quarter. Mobile units are located in the base expedition villages, deployed at stationary settlements and as close as possible to the place of work. The cycle of trips to the place of work and return to the base city is repeated in a pre-planned sequence. The organization of social and welfare services in the expeditionary settlement is calculated on the basis of meeting the daily and periodic needs of workers who live, as a rule, without family members, and includes limited-range commerce and domestic services, organization of leisure activities outside working hours and on rest days.

The shift method of organizing labor is used at a large distance (large compared to the expeditionary method) of the objects under construction from the locations of construction enterprises. Therefore, with this method, working personnel changes at relatively small fixed time intervals (a week or a decade). Civil and erection works are carried out by shift personnel, who, during their stay at the construction site, live in specially created shift camps and systematically return to the location of the construction organization and their permanent place of residence.

The condition for the use of rotational duty is the presence or organization of an interconnected system of housing and production bases, including the housing and production complex of the base town with a developed social infrastructure for permanent residence, cultural and everyday services for workers and a shift camp designed for temporary residence of workers without family members and meet their daily needs. The near border of the rotational construction zone is determined within the duration of the traffic movement of 1-1.5 hours. The combination of rotational and expeditionary methods is defined as the expedition-rotational method. For expeditionary and rotational methods of organizing construction, the use of mobile buildings and structures, which are classified, is of great importance:

· By type of mobility - for containers, consisting of one block-container of full factory readiness and collapsible, consisting of separate block-containers connected in a single system at the place of operation;

· Performance in accordance with climatological conditions in the north, normal and south;

· Functional purpose - for production, storage, auxiliary, residential, public and their varieties.
