shoring and bulk excavation solutions

Project: Chiswick, New South Wales

An absolute joy to have been involved in this project. The client knew exactly what he wanted (and what he didn’t want). The builder was a genius. The architect – PL Projects – was focussed, firm, yet fair. And the team at ACSES Engineers just loved working on it.

ACSES Engineers designed both the bulk excavation solution and the various building structures. Utilising our finite element modelling (FEM) capabilities, we were able to eliminate the need for shoring works by taking advantage of the geotechnical parameters of the site. The FEM analysis verified that our vertical cut solution could safely be carried out without adversely impacting the neighbouring structures.

Again using our FEM expertise, ACSES Engineers designed the superstructure as a concrete framed solution made up of off-form reinforced concrete columns, walls and stairs. To achieve various parameters set by the architect, we designed the suspended slabs as post-tensioned solutions.

The level of detailing required for this master piece was ‘unbelievable’. From the concrete pool rising out of the ground with the infinity edges. To ‘the box’ suspended two levels over the Lower Ground Floor and cantilevering out 5m past its supports. To the off-form concrete walls almost 8m tall that needed to be poured in one go. To the ‘zig-zag’ stairs that could only be 100mm thick or the cantilevered stairs that could be no thicker than 110mm – the end results make all that work well worth the effort.

Congratulations to all involved.

ACSES Engineers are incredibly proud to have been part of the Design Team and honoured to have been the Project Structural Engineer for this development.

Project: 1 Bede Street Strathfield

The structural frame at 1 Bede Street Strathfield has been completed, and the builder has done an amazing job in an incredibly short time.

General site specs:

  • Five Storey Building
  • Two below ground basements
  • 12 Residential Units

ACSES Engineers designed both the shoring and bulk excavation solutions, as well as the building superstructure.

Given the relative small size of the development, cost was a major driving factor for the client who gave us a very specific project brief – “fast, cheap and safe – make it happen”…

Utilising our finite element modelling capabilities, we were able to minimise the shoring works required to support the two level excavation face. Our modelling took advantage of the geotechnical parameters present at the site and ACSES Engineers were able to design a cantilevered pile wall solution with shotcrete infills.

Again using our FEM expertise, ACSES Engineers designed the superstructures as a concrete framed solutions made up of columns and walls using the Rediwall product wherever possible. This eliminated the need for traditional vertical formwork and resulted in further savings in time and cost. The slabs were all designed as conventionally reinforced slab solutions and the individual units were partitioned using lightweight non-load bearing walls made from fibre cement (Hebel) and framed Gyproc.

The project was architecturally designed by Ghazi Al Ali Architects and ACSES Engineers are proud to be part of the Design Team and honoured to be the Project Structural Engineer for this development.
