Wiggins Island Coal Export Terminal GC07 and GC08

Home > Projects > Wiggins Island Coal Export Terminal GC07 and GC08

The Wiggins Island Coal Terminal (WICET) is located at Golding Point and forms part of the existing Port of Gladstone. The terminal has been designed to cater for future coal demand worldwide. The project involved completing the civil and concrete works for the rail receival facility and overland conveyor. BMD also undertook civil and structural works within the Gladstone-Mt Larcom Road corridor including roadwork and bridges for public and project related use.

Aurizon would like to congratulate you and your team on your recent success. The jacking of the tunnel has been closely monitored by the Aurizon team due to the proximity of works to a major asset.

Throughout all stages we have been pleased to work along side your team, primarily due to their willingness to understand our concerns.

We have appreciated both your commitment to personal safety and your understanding of the importance we place on the efficient operation of trains throughout the site.

At an operations level we recognised your willingness to provide us with up to date information along with practical solutions.

Project Manager, Aurizon

Scope

BMD successfully completed a technically challenging jacked box tunnel without disruption to the over-lying railway and construction was undertaken safely in a live rail environment which saw a coal train passing every three minutes.

Specifically, the scope of work included:

53 metre long jacked box tunnel with an 8 metre by 4.5 metre cross sectional area, all constructed under a live rail service operated by Aurizon
80 metre long arch tunnel and 90 metre long in-situ cut and cover tunnel
rail receival building – 3250m3 concrete structure extending 12 metres below the ground and 10 metres above the ground
5.6 kilometres of overland conveyor foundations
constructions and demolition of temporary works associated with jacked box tunnel construction
construction of the substructure for the twin rail bridges.

Outcomes

BMD recognised the hazard working in a live rail environment posed and implemented solutions to eliminate safety risks. One such solution was the creation of a customised canopy structure in collaboration with the client, as well as modifying the original design from a 220 diameter directional drill to a 460 millimetre full clutched micro-tunnelled structure.
