School for 11 grades (422 students) - Stroygenplan, calendar plan

Brief description of the object

For this construction area, the estimated ambient temperature is 30; wind speed head 0.44kPa; weight of snow cover is 0.98kPa; fire resistance degree - the second; orientation - free; engineering and geological conditions - normal.

The school building has 2 floors with a basement adapted for household premises. The dimensions of the ground part of the building are 43700mm wide by 57300mm long. The basement has dimensions 57300mm 34800mm.

Foundations - cast-in-situ concrete, concrete class B5, bout M50. External walls - large light concrete blocks. Internal walls - large railway blocks. Partitions - gypsum concrete panels. The roof is a combined flat unvented with an external drain. The roof is a flat roll, of 4 layers of ruberoid, insulation foam concrete. The largest weight of the mounting element (coating panel) is 7.48t. Construction volume 17272. The total building area is 4484.8.

Heating - from outdoor networks. Ventilation is influential, mechanically induced and natural.

3. Selection of main work methods

For the most high-quality and fast process of erection of construction products - the finished building, it is necessary to use the existing fleet of machines and mechanisms as comprehensively as possible, to combine the simultaneous execution of various works on the site as much as possible and to prevent interruptions in technological processes requiring continuous execution, such as the construction of monolithic structures, directly on the construction site .

Works that involve the main mounting mechanism must be performed in at least 2 shifts. For zero cycle erection, the main mounting mechanism is the KS3561A automobile boom crane, and for the ground part of the building the caterpillar crane SKG160BS. For the construction of the monolithic foundation, a concrete pump with a capacity of 10 m3/h was adopted.

The adopted methods of work execution provide for complex mechanization and use of high-performance construction machines that ensure high quality of work and labor safety, continuous and uninterrupted construction process.

8. Planning Principles

The construction schedule of the facility is designed to determine the sequence and timing of work during the construction of the facility.

The initial data for scheduling design are:

- Drawings of architectural and construction part;

- Design part drawings;

- CIW volumes;

- Building volume;

- Adopted methods of work and mechanisms;

- Labour intensity and machine time costs;

- Storey, configuration and dimensions of the building;

- Standard duration of construction.

When designing the schedule, it is necessary to comply with the requirements of SNiP 3.01.0185 (2005) (Construction Organization). The main work on the construction of the facility should be started only after the completion of preparatory work.

On-site preparatory works shall include:

- Handover and acceptance of geodetic basis;

- Planning of the construction site area;

- Cutting and storage of soil layer used for land reclamation;

- Drainage works;

- Arrangement of permanent and temporary roads;

- Laying of engineering networks of water, power and heat supply, sewerage, etc.;

- Installation of construction site inventory temporary enclosures;

- Arrangement of storage areas and premises for materials, structures and equipment;

- Communication organization;

- Provision of the construction site with fire-fighting water supply and equipment, lighting and alarm equipment.

It is necessary to strive for a constant number of workers on site. A change in their number is allowed up to 20%.

Take into account the maximum combination of work by time, process sequence, grouping into one complex "work" several works performed by one team. For example, brickwork, lintels, slabs, and balcony slabs.

Preparatory works shall be technologically linked to the overall flow of main construction and installation works.

10. Calculation of storage areas

Warehouses must be located in the area of the installation mechanisms. Closer to the crane are heavier elements and most often used. It is necessary that from any parking lot the crane can take any material. The width of the passage is 3 m. Passages for people 1 m. The distance between the stacks is 20 cm. The height of the stacks is up to 2.5 m. The elements are laid in a position close to the design one in cassettes with gaskets. The need for warehouses and open warehouses is determined by calculation and is summarized in Table 7.
