BFCA was contracted by UrbanOne builders to design and construct the temporary shoring works for an excavation pit with up to 4 basement levels. BFCA constructed a hybrid shoring system with a secant pile wall through the high permeability soil layers and timber lagging below. Perimeter of the shoring wall was 254m, retained height up to 12m, overall visible shoring area of 2,763m2. BFCA used 2 BAUER BG28 piling rigs to install the vertical drilling. As horizontal support 170 temporary tie-back anchors were installed utilizing up to 2 KLEMM drill rigs.
