Tomago Gas Tank

Installation of Vibro Compaction to strengthen liquefiable sand layers

Location: Tomago, NSW

Client: CB&I Constructions

A new 60m diameter LNG tank, with its accompanying 14m diameter firewater tank, were to be built on a greenfield site in Tomago as a gas distribution centre. Site investigations had revealed potentially liquefiable sands down to 8m below the site, which needed to be strengthened before construction could begin.

Port Botany Stormwater Pits

Installation of jet grouting to complete two in situ reinforced stormwater pits

Location: Sydney, NSW

Client: McConnell Dowell

Two reinforced concrete cast insitu stormwater pits, 5m by 2m and 2.5m deep, were needed as part of the Port Botany Terminal 3 expansion project. The original design for the pit foundations comprised a steel frame connected to counterfort baffles beneath the pits, all constructed below the water table. McConnell Dowell approached Keller Ground Engineering (KGE) to develop an alternative foundation solution.

Overseas Passenger Terminal

Installation of permanent vertical and raked multi-strand ground anchors

Location: Sydney, NSW

Client: Sydney Ports Corporation

With cruise ships visiting Sydney growing larger, it was necessary to extend the city’s Overseas Passenger Terminal wharf by 60m and build a new northern mooring dolphin just off-shore. Keller Ground Engineering, working in partnership with Waterway Constructions, designed and installed ground anchors to allow for the higher mooring loads.

NCIG Flyover

Utilisation of Mass Soil Mixing, Deep Soil Mixing and Controlled Stiffness Columns to improve the foundations for the NCIG Flyover

Location: Newcastle, NSW

Client: Aurecon Hatch (for NCIG)

A new flyover was needed to relieve congestion at a rail junction at the NCIG and Port Waratah coal terminals. The project involved constructing 1,500m of rail embankments, the bridge, rail lines and signalling. Work was carried out within the rail corridor, next to the active mine and across RAMSAR wetlands.
