ACSES Engineers designed a shoring and bulk excavation solution that extended four levels below Devlin Street, one of Sydney’s busiest roads.
Site access was limited to only the single carriage laneway at the rear, and large tenanted commercial buildings either side of the development were supported on high level foundations that needed to be protected as well. Utilising our finite element modelling capabilities, we significantly reduced the required shoring works by designing an anchored pile and shotcrete wall to support the excavated face above the Class IV material, and then vertically cut the rock strata down to the bulk excavation level. This resulted in massive cost and time savings for the builder YTO Constructions, who must be congratulated on successfully carrying out the detailed works. To further reduce construction time, we designed the superstructure as a concrete framed solution made up of columns and walls using the Dincel Wall product, which eliminated the need for traditional vertical formwork where ever possible. ACSES Engineers are proud to be part of the Design Team and honoured to be the Project Structural Engineer for this development.
