Regensburg, main fire station

Customer: Stadt Regensburg
Construction period: 19 months Year of Construction: 2021–2022

: Building technology, administration, training, and recreation areas were completed during the first construction phase of the building project and are already used by the fire brigade. The central structure connects the administration and the integrated control centre. As both building parts are already being used, construction works (in the 2nd construction phase) are carried out during operation of the fire brigade. In the basement there is a bunker which was built during the years 1963/64, which will not be demolished - but the new building will be constructed on top of it. The ground floor is mainly used as vehicle depot. On the upper floors there are recreation, office, rest, sanitary, and teaching rooms. In addition to that, the areas around the door will be equipped with a projecting roof made of reinforced concrete with the requirement fair-faced concrete SB3.
: The stabilisation works and building of the ground slab of the vehicle depot on top of the bunker. The new building including prefabricated construction parts with bend-proof connections is connected to the existing buildings on both sides. Complicated construction of the projecting roof in fair-faced concrete with connections to the existing buildings by means of adhesive dowels and auxiliary steel construction. Production of in-situ concrete walls due to difficult geometry with special single-faced formwork produced on site for concrete sections of 30 cm of height. Conversion works of existing buildings were carried out during operation of the fire brigade, while the operation of the integrated control centre had to be guaranteed day and night. Supports or trusses were put up as floating construction, before the foundation or the abutment could be concreted.
: 1 tower crane and 1 telescopic forklift
: 420 m³ culvert foundation up to 5 m deep
: 5,000 m³ concrete
: 800 t reinforcement steel
: 2,000 m² floating ground slabs, sloping and with industrial floor heating
: 274 prefabricated parts (supports, trusses, bearers, walls, protruding roofs, railings)

Study/conference centre Mannheim Castle

Customer: Vermögen und Bau Baden-Württemberg, Amt Mannheim und Heidelberg, Mannheim
Construction period: 12 months Year of construction: November 2015–November 2016

In connection with the extension of Mannheim Business School at Mannheim Castle an underground study centre with two semi-circular lecture halls is built. The draft created by Architekturbüro schneider+schumacher shows a bowl-shaped section and opens to the garden of the Castle by means of a large glass facade. Two dome-shaped roofs give an open feeling of space to the lecture centres. At their highest point they surmount the upper edge of the 45 cm thick ceiling of reinforced concrete by 1.25 m. The infrastructure of the newly created building is installed by connecting it to the existing buildings. In order to do this, approx. 7 m had to be excavated in very narrow spatial conditions. Afterwards the exterior foundations of the Castle were broken through and the new building was thus connected to the existing structures.

PARTICULARITIES

The moulds for the freely formed dome-shaped ceilings were planned by LEONHARD WEISS by the division work preparation and manufactured at the new mould construction hall.

QUANTITIES

250 t steel

2.200 m3 concrete

Academy for Film and Television / State Museum of Egyptian Art, Munich

Sophisticated construction project with an interesting inner life

Customer: Bavaria, represented by State Construction Authority 2, Munich
Construction period: 22 months Year of construction: 2007–2009

: The underground museum is characterized by elongated hall-like rooms. The design of the walls, ceilings and display cases was carried out with black-colored concrete, class 2 architectural concrete in a waterproof design. The 20 m high portal dominates the entrance to the museum, with its ocher-colored concrete and colored aggregate, core layers that remain visible and rough texture. The academy is divided into two areas - the almost windowless base section with ocher-colored architectural concrete (rough texture) and the glass section atop it. The glass section is supported by two steel concrete composite truss girders 150 x 10 m, which span the foyer, cinema and the studios.
: Dimensions 150 m x 40 m
: 2 lower and 5 upper floors
: 35,000 m3 concrete
: 110,000 m2 form work
