About the project

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.

Scope

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

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

Rail receival building – 3250m3 concrete structure extending 12 metres below the ground and 10 metres above the ground

80 metre long arch tunnel and 90 metre long in-situ cut and cover tunnel

Constructions and demolition of temporary works associated with jacked box tunnel construction

5.6 kilometres of overland conveyor foundations

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.
