Open pit protection – ZTC, Rijeka
Zapadni Trgovački Centar is located in the west part of the city of Rijeka with an area of 57.000 m2. To ensure the stability during the construction and exploitation phase, due to a change in technology execution and the form of the building, an open pit protection design was made. The open pit had a maximum depth of 21,20 m. Provided measures included an installation of a sheet pile wall, geotechnical anchors, rod anchors and reinforced shotcrete, drains and an execution of jet grouted piles. Measurements and observations of provided measures were conducted during the construction and exploitation phase.
