The step of the columns in the longitudinal direction is 6,24 m, the step of the columns in the transverse direction is 10,0; 6,0; 3,3 m The main structures of the building: slab foundation, columns, beam ceilings, stiffening diaphragms. The floor level of the first floor is 0,000, located at a height of 0,300 m above the planning level around the building. Finished floor mark 0,000, corresponds to abs. . Communication between floors is carried out by two double-flight stairs located symmetrically in the extreme axes. Also with the help of two passenger elevators - adjacent to opposite facades. To communicate the first two floors, an escalator is additionally provided. Foundation. The foundation under the building is slab 600 mm thick (with banquets 200 mm under the central row of columns) on a natural base. The depth of the sole relative to the ground is 1,5 m, the depth of the pit is 2,0 m. After excavation of the pit, the base is compacted with crushed stone fr.20 ... 40 mm, layer thickness 250 mm, sand preparation 650 mm thick from medium-sized sand with layer-by-layer compaction up to K = 0,95 is poured over the crushed stone.

At a distance of 15,7 m from the projected building, there is the building of the Varshavsky business center, built in 2007, the building has five floors and underground parking. By design, the building is framed from monolithic reinforced concrete, on a pile foundation of bored piles. According to the results of the inspection, the building belongs to the I-category of technical condition according to TSN 50-306-2004 (admissible additional draft is 5 cm). Since the FOC building has a draft of no more than 12 cm, the distance to the business center building is at least 15,7 m, and the building is being erected without vibration loads from piling, the impact on the existing building will not exceed permissible values. Measures to ensure fire safety. The design solutions adopted in the project provide fire safety, structural reliability of the building, the required thermal protection of the building in accordance with the "Technical Regulations on Fire Safety Requirements", STO 36554501-006-2006 "Rules for ensuring fire resistance and fire safety of reinforced concrete structures", SNiP 23-02-2003 "Thermal protection of buildings". Building structures are designed in accordance with Table 4 of SNiP 21-01-97 "Fire safety of buildings and structures" and the Technical Regulations on fire safety requirements.
