WICET GC10 Bulk Earthworks
The Wiggins Island Coal Export Terminal (WICET) is a multi-billion dollar coal export facility which will be situated west of the existing RG Tanna Coal Terminal in Gladstone Harbour. The Abigroup Golding Joint Venture was created to combine the resources of both companies to undertake the GC10 Bulk Earthworks for the construction of the terminal. Site works for this $300 million project began in September 2011. The scope of works includes bulk earthworks north of Hanson Road, dredge spoil bunds, reclaim tunnels, foundation concrete works, site roads, overland conveyor embankments and a barge wharf. The GC10 package is expected to be completed by mid-2013.
Daunia Mine is BMA's new metallurgical coal mine currently under construction in the northern section of the Bowen Basin. Bechtel (the EPCM contractors managing on behalf of BMA), awarded Golding the two contracts for the construction of the mine valued at $31 million, for the development of bridges and culverts, and $132 million, for bulk earthworks. The bridges and culverts contract involves the construction of a haul road rail overpass bridge over the Norwich Park railway line; construction of three smaller bridges over an underground conveyor circuit for train load out facilities; construction of the New Chum Creek fishway passage culverts and the upgrade of the light vehicle access road. The bulk earthworks will involve three million cubic metres of earthworks, one million tonnes of pavement materials, 600 thousand square metres of lined dams and 50 kilometres of pipes and conduits.
This project is the $2b second stage of the former Comalco Alumina Refinery. The Golding contracts included Site Development, Concrete, Civil Infrastructure and Wharf Construction. The Site Development works included bulk earthworks, fencing, sewerage, drainage, roadworks, construction laydown and assembly areas. Golding moved more than 2 million bcm of cut to fill material in an eight month period. To achieve this, Golding used in house mining equipment to supplement the conventional civil earthmoving plant.
As a joint venture partner, Golding was responsible for undertaking the earthworks and civil construction for the first stage of the Comalco Alumina Refinery, at Yarwun 10km north west of Gladstone. The work included site clearance, fencing and bulk earthworks. Later work included bulk earthworks, installation of storm and sewerage services, structural concrete foundations, roads, seawater and effluent pipelines, and construction of the jetty and wharf.
The $1.2 billion project was a recent large-scale power generation project developed in Queensland under the State Government's Clean Energy Policy. Golding's infrastructure work for the Power Station involved site clearing and stripping topsoil, construction of three dams and four storage ponds, preparation of the power bench area, bulk excavation for the main structures, construction of the Kogan bore pipe line and pump station and construction of the concrete ROM hopper structure. Achievements on the project included 125,000 manhours free of Lost Time Injuries, and close liaison with Traditional Owners to manage and preserve areas of Cultural Heritage Significance.
Golding completed bulk earthworks for construction of the new $1.5b hospital. The scope of works included cut to fill, export of surplus material, temporary pavements, stormwater and sewer, and a 435m2 vertical retaining wall.
Golding undertook several contracts as part of this major expansion project. These included Row 8 preparatory earthworks, consisting of 250,000m3 of bulk earthworks. Two further contracts required the excavation, crushing, screening and stockpiling of site won materials to produce over 600,000 m3 of various product classes for use as fill, infill and road base on site. Civil works were performed as part of a new stacker/reclaimer bund and coal stockpile pad. Successful completion of these projects led to a further contract for the construction of two sedimentation dams with associated electrical, pipework and drainage structures.
Construction of the new rail receival pit at the Dalrymple Bay Coal Terminal consisted of a large concrete retaining structure some 22m deep. The scope of works included a piled ground support retention system shotcreted and anchored for stability, conveyors and concrete conveyor tunnel. This package of work was part of the Dalrymple Bay Coal Terminal 7X expansion program.
Golding project managed and undertook the civil construction component of the third wharf to increase the Gladstone Port's capacity from 30m tonnes a year to 40m tonnes. The project included widening of the existing approach jetty by two deck girders, infill of two areas of deck voids of the first berth, and construction of the third berth.
The Neweipa Wharf Upgrade in far north Queensland involved the extension of the existing wharf by 40m, including the installation of marine piles, structural steel and wharf structure and replacing existing fenders. Due to access constraints the new berthing and mooring dolphins were constructed from a piling barge. The extension of the new ship loader on the western wharf now enables the loading of two ships simultaneously.
This project involved the construction of a system to maximise the harvest and storage of floodwater for use in coal processing. The system allowed the water to be distributed from various dams including a new 3000 ML dam via two pumps located in Eureka Creek. Each dam is linked by poly pipe of various diameters.
Golding undertook construction of infrastructure for a new underground longwall mine at an existing ramp into the Goonyella Riverside Mine. Work involved drill and blasting of the existing highwall; removal of Goonyella middle seam coal; removal of mud and silt by truck and dredge; compaction of overburden material; in-pit roads, and open lined and unlined drains. Golding installed in-pit conveyor ramps and constructed a tailgate pad and three maingate pads and steel Hel-cor culverts.
