Utilities infrastructure specialist Rob Carr was amongst the national winners hailed by the Civil Contractors Federation (CCF) for civil construction excellence at the 2018 Earth Awards.

Celebrating 25 years, the prestigious CCF National Earth Awards recognised finalists from 42 projects who gathered in the Great Hall of Parliament House in the nation’s capital.

Rob Carr’s Green Square Stormwater Drain project in New South Wales was declared winner of the Project Value $10M – $30M category, emerging triumphant against impressive competition from other projects across the country.

Rob Carr General Manager Angelo Soumboulidis congratulated his team members who had worked diligently on the most challenging, and at close to two years’ duration, longest running project in the company’s history.

“Our team is experienced in working in tight urban environments, but the Green Square project really tested us.

“The team faced constructability challenges, difficult ground conditions through former swampland, and frequent incidents of buried industrial waste objects that hampered progress—however they remained committed to safe, timely delivery and developed innovative solutions.”

Mr Soumboulidis gave credit to Rob Carr’s client on the project—the Drying Green Alliance—for having the foresight to include Rob Carr in the planning and design development stages.

“Through this involvement, we were able to offer trenchless construction solutions that were a lot more cost effective and significantly less disruptive than the original open trench methodology proposed,” said Mr Soumboulidis.

As part of the project, Rob Carr delivered a new 2km stormwater drain that will reduce hazardous flooding in and around the new Green Square town centre area.

In delivering the new stormwater drain system, Rob Carr microtunnelled nearly 4km of DN1800 concrete jacking pipe (550m of twin parallel lines and 964m of triple parallel lines), constructed five caissons (varying diameters between 10–12m, depths between 7–10m), constructed complex civil structures within the caissons and completed eight conventional shored shafts (up to 6m deep).

Rob Carr’s Western Australian team also represented their state and the company at the awards, with their City Beach project a finalist in the $5M to $10M category.
