Constructive decisions

The project for the renovation of the building of an apartment building was developed on the basis of the terms of reference for the design within the framework of the contract and technical report. The existing building is a 9-storey residential panel building, built in 1968 according to a standard project of the II-49 series. Exterior walls made of expanded clay concrete panels, 340 mm thick (front) and 400 mm (end). Internal supports made of reinforced concrete panels, 140 mm thick. The internal transverse walls (stairwells) are reinforced concrete, 300 mm thick. Coating of prefabricated reinforced concrete slabs grades "PPs" and "PP" for prefabricated reinforced concrete beams of trapezoidal section, (overlap above the 9th floor). Attic ceiling Reinforced concrete ceiling of prefabricated solid reinforced concrete panels per room, 140 mm thick. Insulation - vapor barrier - 1 layer, cement fiberboard, t = l50mm, cement-sand screed, t=30 mm. Roofing made of 3 layers of roofing material on bituminous mastic, was replaced in 2005. There are air vents in the attic level. 200x440 mm. Drainage - internal organized. The fence is metal. Exit to the roof and to the attic is carried out through insulated wooden hatches. 1000x1000 mm and doors sec. 1050x1050 mm. Wooden window sashes with separate sashes. In some apartments, window blocks made of PVC profiles with double-glazed windows are installed. Entrance doors are metal.
