2.Technology of works execution.

The foundation of the building is driven piles with the subsequent arrangement of the monolithic pile. Internal and external walls - brick, floors are prefabricated. Panels are made of expanded concrete. The roof is flat from rolled materials on bitumen mastic. The building consists of 5 typical sections. The size in plan is 78 × 78mm. The configuration of the building in the form of the letter "D."

The construction of a prefabricated monolithic building is carried out by a tower crane. A view of the sling device for each element is shown in Table 3. Installation is performed sectionally. Installation of prefabricated structures is carried out by the method "on the crane," i.e. from the most remote part of the building from the crane towards the crane. Installation is carried out from purchased warehouses, which are located in the crane installation area.

Organization of works on erection of structural structures and floors by example of one of floors:

1. Installation of columns and girders;

2. Arrangement of external and internal walls;

3. Installation of santech. cabins and ventilation units;

4. Installation of elevator shafts;

5. Installation of stairways and platforms;

6. Arrangement of floor slabs.

4. Basic principles of planning schedule design.

The construction schedule on the basis of the general organizational and technical scheme establishes the order and terms of construction of the main and auxiliary buildings and structures.

According to the calendar plan, schedules are made for the need for work personnel, material resources, basic machines and transport. The volume of construction and construction works and the need for structures, parts, semi-finished products and basic materials are determined by the data of typical projects, analogue projects or by the current directories and calculation standards.

The initial data for scheduling is:

- estimated and other parts of the project (RP), including separate sections of the PIC;

- work scope sheets, calculations of necessary resources, organizational and technological diagrams of construction of main buildings and structures, and description of methods of complex construction and construction works;

- regulatory and policy deadlines (set deadlines for the construction of the complex and its parts) for the construction of the facility.

The basis for the construction of calendar plans is the principle of in-line construction. To speed up the work, it is advisable to combine the work. The correct combination of work in time makes it possible to achieve conditions under which not only the duration of construction is reduced, but also a more rational use of resources, both material and labor, is achieved. The organization of in-line production in construction provides for:

a) splitting the production process into separate works, preferably equal or multiple in terms of labor intensity;

b) establishment of expedient sequence of works execution and interconnection of interrelated works into the overall aggregate process and their synchronization, thereby achieving continuity of construction production;

c) fixing separate types of work to certain teams of workers, establishing the sequence of inclusion of individual objects in the flow and the movement of teams in the process of performing work.

5. Construction Master Plan.

5.1. Construction Plot Plan Design Philosophy.

The construction site plan is called the site master plan, on which the layout of the main installation and lifting mechanisms, temporary buildings, structures and installations built and used during the construction period is shown.

The construction plan is part of the integrated construction documentation and its solutions should be linked to the rest of the project, including the accepted work technology and construction deadlines set by the schedules. Construction plan solutions shall meet the requirements of construction standards. The solutions of the construction plan should ensure the rational circulation of cargo flows at the site by reducing the number of transshipments and reducing the distance of transportation. These requirements, first of all, apply to mass and especially heavy goods. Proper placement of installation mechanisms, installations for the production of concrete and mortars, warehouses, pre-assembly sites is the main solution to this problem. The construction plan should ensure the most complete satisfaction of the domestic needs of construction workers, the decisions made should meet the requirements of safety, fire safety and environmental protection. Temporary construction costs should be minimal. Their reduction is achieved by using permanent facilities, reducing the volume of temporary buildings. The object construction plan is designed separately for all types of buildings and structures under construction included in the civil construction plan. For complex objects, a construction plan can be drawn up for various stages and types of work.

The initial data for the development of the object construction plan are the site-wide construction plan, made at the previous stage of design, the schedule and process charts, the PDP of this object, updated calculations of resource requirements, as well as detailed drawings of the building.

The object construction plan is compiled by the general contractor or on its behalf by a design and technological organization.

When designing an object construction plan, it is not enough to determine the dimensions of the storage rooms in the area of ​ ​ the lifting mechanism, it is necessary to lay out and assemble structures by types and grades, accurately show the place for certain materials, packagings, equipment and equipment. Once the warehouses have been placed, they are moved to a temporary structure reference. The next stage of the design is the binding of temporary communications, including the point of connection to permanent communications.

5.2. Design of temporary buildings and structures:

During the design, it is necessary to determine:

- Number of workers;

- list and number of temporary buildings and their location;

- places and methods of connection to engineering networks.

Ratio of categories of workers:

- working 85% of Nmax - 145chel.;

- ITR 13% of Nmax - 22chel.;

- MOS 2% of Nmax - 3chel.;

Total from Ntl = 170chel.;

Design areas of domestic premises are determined in accordance with the established number of personnel and calculation standards. The calculation results are presented in the form of Table 5.

The need for temporary administrative and sanitary buildings when designing master plans is determined by the maximum number of workers per shift. The number of workers is taken from the labour demand schedule.
