A Victorian water utility and its contractor project teams have won two awards for excellence in civil construction at the 2016 Civil Contractors Federation Victorian Earth Awards.

South East Water and contractor Interflow’s St Kilda Road Main Renewal Project won in the $1-5 million project category, while the 6th Avenue Rising Main Renewal Project in Rosebud, delivered with Fulton Hogan, Delplant and Beca (FHDB), won the $5-10 million project category.

The St Kilda Road Main Renewal Project involved the replacement of 1.4km of cast iron main dating back to 1868, which lay alongside a tramway, four lanes of traffic, a bicycle lane and more than  200 iconic elm trees.

To minimise disruption to traffic and residents, South East Water and Interflow undertook nine months of community and stakeholder management, working with parties as varied as the Alfred Hospital, the Melbourne Fire Brigade, the Bicycle Network, two foreign consulates and up to 6500 residents.

Work was carried out at night, replacing 200m sections at a time. The road was then reinstated and reopened in time for the morning peak hour, to minimise disruption to commuters.

When the project concluded in August 2015, a survey of residents and businesses found that 84 per cent of respondents were satisfied or very satisfied about the project’s ability to minimise disruption.

The 6th Avenue Rising Main Renewal Project upgraded critical infrastructure on the Mornington Peninsula to support the region’s seasonal population growth.

Receiving wastewater from areas as far apart as Safety Beach and Portsea and transferring it to Boneo Treatment Plant, a 1.8km section of rising main in Rosebud was approaching end of life, and required replacement without interruption to customers and traffic, and before the summer holiday season.

South East Water worked closely with FHDB under their collaborative term agreement to manage risk and meet the project’s timeline.

This included the delivery of upgrades in a live sewer environment, and one of the largest sewerage pumping station shutdowns seen in South East Water’s network, in order to complete the upgrade by November 2015.

General Manager for Asset Creation at South East Water Charlie LittleFair said, “Through these projects, Interflow and FHDB have enabled South East Water to deliver complex, high risk infrastructure upgrades while minimising disruption to the community.

“The projects highlight what can be achieved through good contracting, close collaboration and strong relationships, and I congratulate everyone involved for their hard work.”

Both projects are now eligible for the National CCF Earth Awards to be held in Canberra on 4 November 2016.
