A new shoring system from Coates Hire was used by SA Water during the construction of a new 9m deep pumping station.
Constructed in 1935, the Queensbury Wastewater Pump Station at Hendon in South Australia is a key facility in the SA Water network, collecting wastewater from around 20,000 properties and supporting a population of almost 50,000 people in Adelaide’s north-western suburbs.
A 12-month project began in January this year to upgrade the ageing infrastructure at the pump station. Needing heavy duty shoring during the construction of the 9m deep pumping station, SA Water and their contractor York Civil called on the Coates Hire Shoring Engineering and Technical Team to design and supply a 30m x 14m shoring system capable of supporting ground loads in excess of 42 tonnes per metre.
Coates Hire supplied their revolutionary new Mega Brace and MP150 hydraulic strut shoring system for the project.
Coates Hire’s new shoring system delivers a unique solution for Australian customers engaged in large-scale excavation projects. Quick and easy to install, the system saves time and money; Coates Hire’s technical team also offers support from project planning to project completion to ensure clients gain the utmost value and cost-effectiveness.
Coates Hire National Sales Engineer, Nigel Robbins explains that a contiguous concrete piled wall was installed to 14m deep around the perimeter, and topped with a concrete capping beam. During the excavation and construction phases of the pumping station, the wall needed to be propped in the temporary state until the internal walls and floors of the pumping station were constructed.
This support was provided by a combination of two levels of Mega Brace around the perimeter along with MP150 hydraulic struts providing intermediate support in order to achieve the required loads.
After extensive preparation works at Coates Hire’s Sydney (Ingleburn), Brisbane (Eagle Farm) and Adelaide (Albert Park) Depots, which included making the struts, testing the hydraulic components and welding an extensive number of high load sheer stops, the 110 tons of equipment were delivered to site and installed in only a few days.
The Coates Hire Technical Team supervised the installation of the system, ably supported by team members from the Coates Hire Albert Park Branch and the York Civil team under direction of their Project Manager Michael Lazaraki. The two large shoring frames were quickly installed, allowing York Civil to progress the works and dig the additional 6m of ground beneath the frames to an overall excavation depth of 9.8m.
Michael Lazaraki expressed his appreciation for the quality of the product as well as service from Coates Hire. In addition to the support, they were also impressed by the speed of installation in difficult site conditions. The clear open areas between the struts afforded by the frame design allowed excavators to work with minimal obstructions, enabling excavation to proceed at pace.
Working closely with Coates Hire’s Technical Team throughout the planning stage provided York Civil with a cost-effective, valuable engineered solution, which has now been expanded to accommodate the provision of other shoring products and well point dewatering to support additional trenching works and manhole construction in various areas of the site.
This project clearly demonstrates the latest capabilities of Coates Hire to provide multi-faceted shoring solutions to meet their customers’ needs, and expand product capabilities and engineering expertise to cope with demanding and complex civil engineering projects.
