SA benefits from Zinfra’s experience

Since Zinfra’s foray into the South Australian market in August 2014, its local presence has grown from a handful of employees at a small depot in Cavan to almost 30 employees at the new, larger depot and warehouse facility in Ferryden Park.

APA Group awarded Zinfra 10.5 km of the gas main replacement works in the Adelaide central business district (CBD) (Area D) after recently finishing a package of 6 km of the same works (Area B).

Area B is bounded by South Terrace, King William St, West Terrace and Sturt Street in the south west of the Adelaide CBD.

Area B works commenced late September 2014 and concluded in March 2015.

Area D encompasses the high-traffic streets of Carrington, Hutt and Pulteney, with a total of 661 customers, with works commencing in Area D in May this year.

The high-density commercial and residential zone required Zinfra to carry out a high level of engagement with the public, as well as liaise with the local council due to heritage overlays in the area, with traffic management required for nearly all the work being undertaken.

When undertaking gas mains replacement work in the CBD, APA Group Capital Works Supervisor Ian Colaco says the company values “putting safety first, delivering good quality work and dealing with end users and their property in a respectful manner.”

Zinfra Project Manager Stuart Hillman said “We met APA Group requirements through the way we completed the job, our work ethic, site set-ups and the way our employees handled the council and the public.”

The various projects Zinfra has completed for APA Group have fuelled the company’s success in South Australia, including gas mains replacement work in the CBD, a long-term mains and services contract in northern Adelaide, and separate compressor station projects at Angaston and Virginia.

The gas mains replacement works involved the insertion of polyethylene “˜tiger’ pipe into existing steel and cast iron pipes to upgrade from a low-pressure to medium-pressure service.

The new pipes will increase reliability and decrease the incidence of leaks and faults.

Experienced Zinfra gas crews are currently completing an impressive 200-300 metres a week of this work in the CBD, with excellent client and end customer satisfaction.

Recruiting locally to keep up with demand, Zinfra is currently seeking gas workers and operators to expand their crews in South Australia.

Zinfra’s South Australia Manager Serge Bondarenko attributes Zinfra’s success in the South Australian market to its “size, focus on safety, experience and ability to deliver cost effective, end-to-end services on gas transmission and distribution assets.”
