RECONSTUCTION OF THE HISTORICAL BUILDING FOKSAL 13 AND 15 IN WARSAW

We were asked to design geotechnical structures to enable reconstruction of historical buildings. Buildings have to meet current standards so load bearing capacity had to be increased and underground garages can be built. A description of the securing construction pit is described below as well as the design of the deep foundation. The construction pit was secured by jet-grouting columns with struts and soil nails. Parts of the walls were underpinned by micropile trestles. Jet-grouting columns were also used for the deep foundation of existing walls
