Construction Description
Rehabilitation and Residential Building
The building is designed with a mixed post-and-wall structure in a masonry-monolithic technology, with prefabricated elements. It is a six-story building with a basement (the underground floor is heated) and a flat, non-ventilated roof. The maximum height of the building is 18 meters, classifying it as a mid-rise building (SW). The building features an underground level beneath part of it. The above-ground portion consists of five dilated segments (5 cm structural joints):
Administrative Wing (A): Axis 1-4 and F-J, with a longitudinal wall structure on a rectangular plan measuring 16 x 13.2 meters in axis; three floors, including the basement; height of 7.6 meters to the top edge of the passive flat roof; dilatation joint between axis 4 and 4’.
Residential Wing (M): Axis 4’-9 and A-D’, with a longitudinal wall structure on a rectangular plan measuring 16.5 x 25.2 meters and an overhanging part supported on beams between axis D’ and E; six floors, including the basement; height of 18 meters to the top edge of the flat roof; dilatation joint at the underground parking level between axis D and D’.
Clinic Wing (P): Axis 9’-13 and F-J, with a mixed post-and-wall structure on a rectangular plan measuring 22.6 x 13.9 meters; four floors, including the basement; height of 11.1 meters to the top edge of the flat roof; dilatation joint between axis 9 and 9’.
Entrance Wing (W): Axis 4’-9 and E-J, with a post structure on a square plan measuring 16.5 x 16.5 meters; one floor plus a mezzanine at level +1; height of 11.1 meters to the top edge of the glass roof structure; dilatation joint from wings A, M, and P.
Greenhouse Wing (S): Axis 9-13 and A-F, with a post structure on a plan of two perpendicular rectangles measuring 11.5 x 8.6 meters (axis 9-11 and A-B) and 31.2 x 11.5 meters (axis 11-13 and A-G); one floor plus a mezzanine at level +1; height of 10.5 meters to the top edge of the glass roof structure.
Foundations: The building is founded on a reinforced concrete box with a thickness of 50 cm, except for wing S, where columns are supported on 100 x 100 cm footings with a height of 50 cm at a depth of 1 meter.
Walls:
Basement: Monolithic load-bearing external walls with a thickness of 50 cm; fire escape staircase load-bearing walls with a thickness of 25 cm; partition walls made of blocks with a thickness of 22 cm; monolithic load-bearing dilatation walls with a thickness of 40 cm.
Floors 0-4: Monolithic three-layer external load-bearing walls with a thickness of 51 cm; monolithic load-bearing fire escape staircase walls with a thickness of 25 cm; partition walls made of blocks with a thickness of 22 cm; light skeletal structure partition walls made of steel profiles with gypsum board cladding with a thickness of 15 cm.
Columns: Solid monolithic columns with dimensions of 50 x 50 cm in sections A and M at level -1, and 60 x 60 cm in section P at levels -1 and 0, while at levels 1 and 2, solid monolithic columns measure 30 x 30 cm. In section S, steel columns are made of HEB 300 profiles.
Ceilings: Densely reinforced transfer slab above the underground parking with a thickness of 70 cm and an axis spacing from 4.1 m to 7.5 m. Inter-floor ceilings are made of prestressed hollow-core slabs with a thickness of 30 cm. Above the entrance area and greenhouse, a truss system is planned: five trusses with a length of 17 m and a height of 150 cm spaced approximately 4 m apart for the entrance area; for the greenhouse (S), truss spans range from 8.2 m to 14 m, truss height is 120 cm, spacing from 5.5 m to 8.2 m.
Beams, girders, "mushrooms": Monolithic beams on the underground level measure 40 x 50 cm, supported on monolithic columns with an axis spacing from 4 to 7.5 m. On the remaining floors in sections W and P, beams measure 20 x 30 cm with spacings from 4 to 6 m. On the ground floor in section P, there are columns with a diameter of 60 cm with "mushrooms" measuring 200 x 200 cm and a height of 30 cm, spaced 5.5 m apart, supporting the cantilevered Clinic wing (P).
Roof: Densely ribbed flat roof with a span up to 7.5 m, ventilated, covered with gravel above section M with a thickness of 50 cm; above sections A and P, the flat roof is covered with a vegetative layer with a total thickness of 70 cm; above sections W and S, the structure is a truss-purlin system supporting the glazing. The roof slopes are 2%.
Stairs: All stairs except those in the greenhouse are designed as monolithic reinforced concrete slab stairs. The stairs in the greenhouse have a steel stringer construction.
Sports Hall Building – Brief Description
The Sports Hall is designed with a mixed post-and-wall structure. Columns support trusses on which the densely ribbed flat roof covered with gravel in the sports hall area is placed. The wall structure is masonry in the locker and sanitary area. The building has three floors, including a basement, which is exposed on the western side (the plaza is at the underground level height). The building is rectangular, measuring 26 x 46 meters.
