Brief description of the construction facility and its design materials.

The construction site "Reconstruction of the building with the placement of an administrative building with trading premises on 91a Chicherina St. in Ussuriysk is located in the area of ​ ​ the existing development. Currently, a 2-story non-residential building is located on the construction site. The construction area is characterized by a temperate continental climate. Design minimum temperature minus 31 ° С. The normative depth of freezing of soils reaches 2.21 m. The relief of the site is calm, flat.

The structural diagram of the building is solved in a monolithic reinforced concrete frame. Spatial femininity of the building is provided by spatial frames rigidly connected to the foundation and joined slab disks.

The project adopted a monolithic foundation slab made of concrete of class B25, has rigid spatial reinforcement with separate rods and grids from reinforcement of class AIII, AI.

Cast-in-situ columns made of concrete of class B25 with corresponding reinforcement by separate rods from reinforcement of class AIII, AI.

Slabs and coatings are cast-in-situ from concrete of class B25 with corresponding reinforcement by separate rods from reinforcement of class AIII, AI.

The external walls of the above-ground part of the building are self-supporting from slag blocks with a thickness of 340 mm with a reinforcement device every three rows of masonry.

The internal staircase of two marches from monolithic heavy concrete B25 has rigid spatial reinforcement with separate rods and grids from reinforcement class AIII, AI.

General part

Organizational Process Flow Chart and Construction Timeline.

After the site is withdrawn and the project is put in kind on the object, preparatory work is carried out:

equip domestic premises for builders, in the premises allocated for these purposes;

organize communications for operational control around the clock;

3. Install temporary fences of the construction site from the parts of the unified inventory fences of the construction sites of Ussuriysk with structures from the profile sheet with posts embedded in concrete blocks, equipped with gates for entry-exit;

at the exit from the construction site, equip an installation with a circulating water supply cycle for washing the wheels of vehicles;

when entering the construction site, install an information stand with the details of the construction site;

perform fire safety measures of the facility (at the entrance to install a stand with a fire protection plan for the facility, equip stands with sets of primary fire extinguishing equipment), organize a smoking place near fire stands;

install containers for the collection of construction waste and household waste;

provide the construction site with electricity, water, telephone communication for construction and installation works. The connection points are provided by the customer;

perform safety measures with identification of hazardous areas, entrances, passageways and install safety posters;

Preparation of construction production.

Earthworks

Excavation works shall be performed in compliance with the requirements of SNiP 3.02.01-87

"Earthworks, foundations and foundations."

Excavation in pits and trenches

Excavation of soil in pits for buildings and structures shall be performed from black elevations by excavator with ladle capacity of 0.5 mZ in volumes required for

backfill, carry the surplus to the distance as agreed with the customer.

Backfilling of pit sinuses, layout shall be performed by bulldozer, with capacity of 130 hp with soil movement up to 10 m in accordance with item 4.9; 4.10; 4.14 SNiP 3.02.0187.

Soil rework in pits and trenches is performed manually. When crossing trenches with effective communications, earthworks shall be carried out in accordance with SNiP 3.02.0187 item 3.22.

Compaction of soil is performed by pneumatic ramming to design elevations.

2.3 Basic requirements of geodetic constructions

When performing geodetic survey work on the construction site, comply with the requirements of SNiP3.01.0384 "Geodetic work in construction."

The Owner is obliged to create a geodetic layout and at least 10 days before the start of construction and installation works to hand over to the contractor the technical documentation for it and the base points fixed on the construction site.

Construction of the geodetic layout should be carried out using triangulation, polygonometry, geodetic passages, and other methods.

The accuracy of the layout should be taken according to Table 1 of SNiP 3.01.0384.

The breakdown works during the construction process shall ensure the removal from the points of the geodetic breakdown base with the specified accuracy of axes and elevations, which determine in accordance with the design documentation the position in plan and height of parts and structural elements of the designed buildings.

The accuracy of the breakdown works during construction should be taken in accordance with the data of Table 2 SNiP 3.01.0384.

During construction, geodetic control of the accuracy of geometric parameters of the designed buildings should be carried out, which is a mandatory part of production quality control.

Geodetic inspection results shall be recorded in the general work log.

Short analysis of object complexity and selection of organizational

technological model of its erection.

Architectural and structural solutions - all typical .

Space planning solutions - An object consists of a typical design with non-typical nodes.

Technological solutions - the ability of an organization to perform repeated construction processes in-line.

The organizations involved in the construction are the general contractor and no more than two specialized organizations.

Conclusion: the building is simple complexity.
