![]() ![]() Deep Excavation "Sparkassenhöfe" Graz, AustriaFor extension of the headquarter of "Steiermärkische Sparkasse", a 14 m deep building pit was excavated in the city center of Graz. In this area, the ground consists of water-bearing fluviatile sediments with high permeability overlying fine-grained, overconsolidated Neogene sediments. The base of the excavation pit was located in the Neogene. When developing the excavation pit support, measures for underpinning adjacent multi-storey buildings constructed in various centuries had to be designed. Furthermore, special care was required for the design of support measures at the change-over between fluviatile sediments and the Neogene. A jet-grouting body in combination with pre-stressed multistrand anchors was used as excavation pit support, for underpinning adjacent buildings and for water-proofing. The Neogene sediments were supported using an anchored shotcrete shell. Services
