Hay Point

BHP Billiton Mitsubishi Alliance (BMA) as part of the HPX3 project desired to expand the existing Hay Point Coal Terminal (HPCT) coal loading facility, south of Mackay, to increase the throughput capacity from approximately 44 million tonnes per annum (Mtpa) to 55 Mtpa.

In conjunction with the expansion project, the existing trestle structure was required to be demolished and removed from the site, once the new out loading trestle and conveyors were commissioned.  The original trestle and conveyor that transported coal from the terminal to waiting bulk carriers for more than 40 years from when the facility opened in 1971 required to be dismantled and removed.

Edwards Heavy Lift provided design services on the $31 million demolition project from initial project methodology and tendering through to detailed design and support during the project.

For this project Edwards Heavy Lift provided the following services:

• Deconstruction methodology development

• Key innovations assisted in developing a more efficient, safe and cost-effective solution

• Temporary works structural engineering for the entire trestle demolition project including:

  • Corrosion assessment

  • Specially jointed crane beams and stool

• Pile restraint to provide access and support to piles during de-construction

  • Detailed engineering reports

  • Detailed engineering and shop drawings

  • Construction advice during project
