Abstract:
The DBCT 7X Project is a major expansion of the Dalrymple Bay Coal Terminal in North Queensland with a total capital cost likely to be in excess of $1.1 billion, excluding financing costs. The project involves more than 35,000 m3 of concrete in a variety of structural applications. This paper discusses some of the key design and construction issues associated with three areas of the works: the rail receival pit comprising a dump station and conveyor tunnel up to 20 m below ground level; precast concrete retaining walls for two new stockyard bunds 1.1 km long and 6.1 m high; and marine works including unreinforced concrete Hanbars for seawall armour and prestressed pre-tensioned concrete deck units for a 3.8 km long jetty and 420 m long berth.
