The heritage listed Horseshoe Bridge in Perth connects the CBD to Northbridge. It was constructed in 1904, with the horseshoe shape designed to fit the approach ramps into a constricted site.


Duratec was engaged by Doric to complete the following scope of works:

  • Corbel and rosette replacement.
  • Abutment padstone repairs.
  • Replacement of ventilation surrounds.
  • Arch steel strengthening.
  • Plaster and render crack repair.
  • Repair delaminated/spalled render and coke breeze concrete.
  • Removal of staining to facade.
  • Reinstatement of loose brickwork.
  • Re-pointing of mortar joints.
  • Masonry wall reconstruction.
  • Repairs to existing columns and bases.


  • Works completed on a tight programme with restricted access due to interaction with multiple subcontractors on site for the duration of the works.
  • The works involved detailed repairs to strict heritage requirements including successfully matching existing concrete corbel and rosette details which are 110 years old.
  • Corbels were created using specialised in-house equipment to produce polyurea moulds which provided significant cost and time savings.
  • Project completed safely with no HSEQ injuries or incidents.
  • Structural rehabilitation of the brickwork was achieved through a crack stitching process, bricks were abrasive blasted prior to being build to achieve a seamless match to the existing structure.
