Solomon Dewatering

27 July 2020

Dunstans have secured a long term service contract with Fortescue Metals Group across their mining operations for the design and construction of Horizontal Dewatering infrastructure.

The new contract stems from the completion of a series of world first successful horizontal dewatering projects over the last 3 years which provide lowest cost of life dewatering infrastructure, enabling greater operational uptime for Iron Ore mining operations.

Crossing The Nerang River

15 June 2020

In May 2020, Dunstans completed a crossing under the Nerang River on the Gold Coast as part of the City of Gold Coast’s Long Term Recycled Water Release Plan. The crossing was one of the largest Horizontal Directional Drilling (HDD) crossings to be constructed in Australia.

Due to the geology, location and diameter of the borehole, the design and methodology was technically challenging and complex engineering solutions were required to successfully complete the works.

Drilling was conducted from within The Southport School, with the borehole passing under the Nerang River, Gold Coast Light Rail and Sundale Bridge and exiting at Waterways Drive, Main Beach, a distance of 900m.

Pilot holes were drilled from both sides of the crossing with an intersect undertaken below the Nerang River utilising Gyroscopic and radar guidance tools. Reaming was conducted using a two drill rig system to ensure continuity of drill pipe from entry to exit at all times during reaming operations. Reaming was conducted in only three stages with 27 inch, 42 inch and 58 inch reaming passes completed using industry leading Sharewell reamers.

A 1200mm OD PE100 HDPE pipe was welded and strung at The Spit, 5km north of the project site. For pipe insertion, the 900m of 1200mm HDPE pipe string was towed along the Nerang River and Broadwater to Waterways Drive with barges, tugs and water police. The pipe was then passed onto land where it was positioned in-line with the borehole and connected to the drill rig for insertion.

East Grampians Rural Pipeline Project contract awarded

15 March 2020

GWMWater has appointed Dunstans Construction Group to deliver the East Grampians Rural Pipeline Project.

This pipeline will secure the future of the region by providing a reliable, secure supply of high-quality water year-round, via 1,600 kilometres of stock and domestic pipeline for up to 530,000 hectares of land.

Dunstans have started working through the planning approvals and design prior to commencing construction later this year.

Cape and Dunstans announce joint venture

26 August 2019

Two of Australia’s leading utilities infrastructure and mining services companies, WA-based Cape and Victorian-based Dunstans Construction Group (Dunstans), have formed a joint venture (JV) to expand their service offering to clients.

The formation of the JV was a natural fit after Cape’s owner, the CFC Group, acquired a stake in the Dunstans business.

Although the two companies will continue to operate as separate entities, they will work together on larger projects, sharing expertise and equipment to seek and deliver larger projects across Australia.

Dunstans Murray Dunstan said the opportunity to join forces with Cape on strategic projects is exciting.

“We have collaborated and competed for the same types of projects over the last decade, so we are well placed to bring both businesses together when joint venture opportunities present themselves,” he said.

Long Beach Sewer Rising

27 February 2019

Dunstans Construction Group was awarded a project by the Public Works NSW for the Eurobodalla Shire Council to install a 1.2km pipeline below the Cullendulla Mangrove Reserve and the Cullendulla Creek to service the growing population in Long Beach.

Due to the urbanised location and the environmentally sensitive nature reserve, Dunstans provided a reduced risk option that addressed the Council’s concerns with the project. Two HDD rigs were used to complete an intersection.

This was one of the largest HDD projects completed on behalf of Eurobodalla Shire Council / NSW Public Works to date. The installation reduces the impact to landholders and the environment by utilising trenchless technology as well as removing the environmental risks associated with the existing pipeline that was exposed along the beach of Cullendulla Mangrove Reserve.

Dunstans successful gas line installation in the Cooper Basin

21 May 2018

Dunstans have successfully completed the installation of a 42km Fiberspar high pressure gas line in the Cooper Basin, connecting approximately 10 gas wells into the Moomba processing facility for Senex and Santos.

Seven facilities were also constructed which serve as tie in points to existing lines and wells, and to allow the “pigging” (cleaning) of the lines to take place.

This gas is to be used to supply the Australian domestic market.

Dunstans has been delivering high quality work to our oil and gas customers over the past 10 years and our reputation in this market has earned us valuable relationships with some of the industry’s leading producers.
