Occasionally there are what we call “special Projects”. These are projects that require us to think outside the square and to come up with a feasible and cost effective solution for concrete placement. Weather it be on land or water , it’s just about the degree of difficultly.
Some of the more interesting ones are shown below.

Hale street link (HSL) is a key component of the TransApex plan to ensure Brisbane is a well connected city for now and into the future.
HSL is the construction of a four lane bridge across the Brisbane River to connect Coro Dr and Hale st with South Bank.
This project will not be your average pumping job as it has some very different requirements. Parts of this job will be completed by mobile pumps
situated on false work bridges, Other parts pumped from fixed lines hanging from gantry frames and also two separate placing booms positioned
on floating barges to access structures in the middle of the river.

The Gold Coast Desalination Project, originally initiated by Gold Coast City Council and now owned by Sure Smart Water (whose sole shareholder is the Queensland Government), is the first large scale water desalination plant on Australia’s eastern seaboard.
Located at Tugun on a six hectare former landfill site, when fully operational the facility will supply 125 mega litres a day of pure drinking water to South East Queensland, one of Australia’s worst drought affected regions. The facility will be a vital element in the State Government’s new $9 billion SEQ Water Grid, Gold Coast City Council’s Water futures Strategy and the State Government’s South East Queensland Regional Drought Strategy Contingency Supply Plan.
The GCD Alliance (an alliance of leading companies appointed to deliver the project and the facility owner) will set a construction record by finalising the complex project by November 2008.

Another pedestrian bridge for the city of Brisbane, this project once again requires pumping solutions outside the norm.. Due to extremely bad
site access on the city side of the project a long fixed concrete pump line was requested as the preferred method of placement.
With greater access on the South Bank side of the Project large long reach booms have been used for the method of placement.
The design and construct contract commenced on 1 October 2007, with project completion scheduled for September 2009, in time for Queensland's 150th year anniversary celebrations. |

The Goodwill bridge is a vital pedestrian link between South Bank and the Brisbane City.
At 500 meters long, from one side of the river to the other this project was always going to be challenging and different to any other pumping
job previously. For various reasons this project required a floating line from one side of the river across to each of the different structures
where a mobile boom pump was placed on a barge to help convey the concrete to the required heights. This concrete was pumped from the river
bank with the help of a high pressure skid pump.
After some early challenges of floating lines verse tidal movement and wash from boats the project proved to be a great success.

As part of the upgrade to the R G Tanna Coal terminal in Gladstone a extra shipping berth and coal loader was added to the wharf. This
required additional dolphins to be positioned for the ships to rest up against and tie off too. As these dolphins stood remotely
off the main wharf access for concrete placement was always going to be an issue. With much planning from John Holland and ourselves the
job proved to be no problem at all.
Concrete was pumped from the land by mobile boom pump into crane kibbles on a barge. From there the barge made its 2km trip to the dolphin
where another barge awaited with a large crane to lift the kibbles and empty them into the trailer pump which then dispersed the concrete into the structure. This proved to be an extremely successful process.
