Quarantine in Prague Zoo

Quarantine in Prague Zoo
Collaboration:Lukáš Pinkava, Jan Přikryl
Investor:ZOO Praha
Project:2002 - 2003
Completion:2003 - 2004


The new quarantine replaces the building destroyed by the major flood in August 2002. The new construction is located in the operational area of the Zoo, above the floodplain of the Vltava river.
The building is designed as a universal quarantine facility for animals ranging from ungulates to carnivores and other mammals, as well as birds and reptiles. The house is based on a simple, pragmatic floor plan. A corridor runs through the center of the layout, leading to stables on both sides. Two of the small stables are adapted for aquatic animals, with a shallow pool. Most of the stables are interconnected by sliding doors. Courtyards are located along both longer sides of the building and can also be interconnected. The courtyards are enclosed with a grid and are partially covered. The courtyards for carnivores and birds also have a grid ceiling. Two rear corner stables are outdoors. Staff service rooms are located at the beginning of the house near the loading ramp.
The choice of materials meets strict requirements for cleanliness and mechanical durability.
The load-bearing structures are monolithic reinforced concrete, with exposed concrete. The perimeter walls are sandwich walls with thermal insulation. The floors are concrete, with stamped tiles in the stables and a crystal additive in the other rooms. The doors and windows are atypical, made from hot-dip galvanized rolled profiles with spruce board fillings. The stables are heated by electric heating cables embedded in a layer of sprayed concrete on the walls and by direct heating radiant panels. The partitions in the staff area are made of exposed brickwork from concrete blocks.
The doors between the stables and to the courtyards are operated from the corridor using rod and cable mechanisms with counterweights. The control mechanisms are hidden in the reinforced concrete walls of the stables. The windows are opened by electric chain openers.
The load-bearing monolithic reinforced concrete structure, made of B30 concrete, consists of longitudinal and transverse walls with a thickness of 180 mm and a ceiling slab with a thickness of 140 mm. Between the insulated and non-insulated parts are doubled sandwich walls with thermal insulation of 120 mm thickness. The outer non-insulated part of the building is dilated into two sections, while the inner part has no dilation. To increase the lifespan of the exposed concrete, a crystallization additive, Xypex, is added to the concrete mix of the walls.
