Pumping stations B1 and B2, TENT B, Obrenovac

Details about the works

Scope of works:

• Fabrication and installation of the building’s steel structure – 245 t
• Installation of façade PIR panels – 2,860 m²
• Installation of roof PIR panels – 950 m²

Specifics:

• The role of the main load-bearing structure is shared by both concrete and steel, with steel primarily providing structural stability.

Description

The building has base dimensions of 34 x 21 meters, with a ridge height of 17 m (lower section) and 25 m (higher section). The structural system is complex (a combination of steel and concrete). Both pumping stations are structurally identical, with Pumping Station B2 being a mirror image of Pumping Station B1.

The steel structure we were responsible for included vertical and roof bracings, internal platforms, monorails, and the substructure for all openings and panels. The connection between steel and reinforced concrete elements was achieved using base plates with dowels (B500B reinforcement), embedded during prefabrication, onto which the steel structure was later welded.

Anticorrosion protection was carried out in accordance with exposure class C4, with the required durability of 15–25 years.
