Bauer completes specialist foundation engineering work for a new biology center at the University of Vienna

The Austrian Bundesimmobiliengesellschaft (BIG) is building a new biology center on behalf of the University of Vienna on an area of approx. 12,000 m2 in the city’s 3rd district. After completion and handover in 2021, more than 5,000 students and 500 employees will find a new home for their scientific work in the new building.

The Bundesimmobiliengesellschaft contracted BAUER Spezialtiefbau Ges.m.b.H and its JV partner Gebrueder Haider Bauunternehmungen GmbH with executing the earthworks, securing of the deep excavation and creating the deep foundation. Existing foundations and embankments with depths of up to 12 m below the existing level were found in the construction field, which required continuous adjustments to the securing of the deep excavation. Due to a design variant, the anchored sheet pile wall and Berlin wall that the building owner had originally planned was replaced by 650 m2 of soil nailing, and, in the sub-area with the greatest excavation depth, by a 95 m retaining wall as a contiguous bored pile wall.A BAUER BG 28 was used to install the piles. © BAUER Group

A BAUER BG 28 was used in the construction of the 8,300 m pile foundation, which has a diameter of 630 mm. Despite the already existing embankments, the foundation piles and the pile wall was constructed successfully in all areas. The subsequent excavation comprised about 42,000 m3 of soil material. Thanks to the early adaptation of the execution planning by Bauer's internal statics department, the great flexibility of the execution team and the rapid disposition of additional equipment, project delays were avoided and the main services were concluded one and a half months head of the planned completion date.
