  • Customised to meet project specific requirements
  • Enhanced quality – made in controlled environment
  • Reduction of waste and on-site labour
  • Speed and simplicity of construction
  • Increased site safety
  • Improved efficiency



  • 8 Chifley Square, Sydney
  • 30-storey boutique premium grade commercial building
  • Five-storey high entrance at street level
  • 3,000 tonnes of reinforcing steel
  • 450 tonnes of highly customized prefabricated columns – CUSTOMCAGE
  • CUSTOMCAGE weight approximately 15 tonnes




  • Supply and installation of four abutments to pick up four mega columns to transfer load
  • Complex abutment cages requiring detailed CAD modeling to avoid bar clashing and difficulty in steel fixing
  • Intensive scaffolding, numerous labour resources and longer time required to manually fix the reinforcing steel
  • High safety risk to do scaffolding and steel fixing in elevated heights
  • Prefabrication, handling and delivery of cages to site
  • Council and road authority restrictions on transportation and time of delivery


  • Off-site fabrication to remove the installation of the abutments from critical path of the project’s program
  • Collaborated with Mirvac and head designers to CAD model the cages to avoid bar clashing and allow for ease of placement on site
  • Provided lifting design and certification to ensure safety in handling and installation
  • Worked intensively with our logistics subcontractors and numerous councils to ensure on time delivery of CUSTOMCAGE within the council and road authority requirements

We did not know how we were going to do it and how to overcome the safety and time challenges of this project. We worked closely with OneSteel Reinforcing and came up with the prefabrication solution of the abutments and columns. Because of the benefits we gained from using prefab in this project, we will do the same on all of our future projects.
