Operational area of the Vltava River Basin

A closed complex of reconstructed and new buildings that meets the needs of modern industrial operations. By the river adjacent to the cycling path stands a new administrative building with a main entrance, along the road a repair hall with a crane track, and connecting workshops. Both parts of the plant are separated by mature greenery. The area of the catchment has significantly improved the original poor condition, including the expansion of green spaces and the addition of a new pedestrian path. The shape and size of the buildings respond to the natural shape of the land and follow its boundaries. The buildings are arranged in such a way as to create differentiated environments both outside and inside the area, forming a barrier that visually and functionally separates the industrial complex from the main communication axes. The two-storey administrative building, rectangular in shape with dimensions of approximately 60.1 x 12.7 m, has an entrance width of 16.7 m. The building is two-storey, with the level of the second floor at +3.650, the lower edge of the roof at +6.515, and the height of the parapet at +8.850. The level ±0.000 is approximately 1.10 m.
The building is founded on foundation footings and strips. Reinforced concrete monolithic strips run over the footings and support the upper structure.
The level of the first floor is raised compared to the surrounding terrain by approximately 1.00 m, which is above the flood level in 2002. Due to high embankments, the floor slab at the level of the first floor is reinforced ("zero ceiling") on the embankments as lost formwork.
The load-bearing system of the building consists of a reinforced concrete monolithic structure, supplemented with prefabricated elements. Vertical elements include columns in the outer wall and further longitudinal outer walls and two transverse walls in the module with an elevator and staircase.
The reinforced concrete wall on the northern side of the building is externally insulated and clad with stone and wood.
Horizontal elements consist of longitudinal beams on both floors. The ceiling of the majority of the first floor is made of 320 mm thick reinforced concrete prefabricated prestressed Spiroll panels. The panels are supported on the perimeter beam and a continuous console in the monolithic wall. In the module with the staircase and elevator, the ceiling structure consists of a 250 mm thick reinforced concrete monolithic slab.
The remaining part of the second floor is covered with a structure in the shape of a hip roof with a slight slope from module A towards B, creating a console of length 1.85 m.
The hip roof is repeated twice in the module, meaning it occurs regularly every 2.70 m (/\/\). Due to the shape, span, and requirement for an aesthetically pleasing underside, a 140 mm thick reinforced concrete prefabricated structure is designed. The front cantilevered part is anchored to the main field with thermally insulating ISO beams.
Internal partition walls in the building are non-load-bearing, drywall, and spatially divide the building into a longitudinal three-section with a central corridor. The internal staircase and elevator shaft are made of prefabricated reinforced concrete.
The external staircase and ramp to the entrance are made of monolithic reinforced concrete, separated from the main building.
The external escape routes to the 1st and 2nd floors consist of steel rolled staircases anchored by welding into the reinforced concrete monolithic wall, and the steps are made of perforated sheets.
The external perimeter walls are glazed.
Along the entire length of the building, on the side facing the river, there is a walkway at the level of the 2nd floor made of modular segments modularly every 1.35 m, bolted to consoles from the beam.
In front of the building on the southern side, there is a reinforced concrete retaining wall designed to withstand increased water levels, thus forming a flood barrier.
At both ends of the building, there are separate stone walls. The walls are stepped in height in three levels, the lowest is 700 mm wide, both higher ones are 800 mm wide. The wider walls contain a space for a concrete core with a reinforcing Kari mesh. An opening is created in both walls, with a wooden lintel above the openings made of solid oak beams.
