Adept Civil has continually proved itself as one of the most knowledgeable and reliable contractors on Australia’s east coast. Fully accredited and massively experienced in the delivery of major projects, the company specialises in the supply and installation of water and sewerage drainage pipelines, pump stations and associated services.
In October 2019, Adept Civil was engaged by Longford Civil to carry out the boring works for the construction of a 4 km gravity sewer main to service the NEXUS Industrial Precinct in NSW. Located 10 km north of Albury, the site is zoned to support large or heavy industrial development and spans the Hume Freeway and the main Melbourne-Sydney rail corridor.
The hub is an extremely busy area, with a common user rail hub operating on site and businesses functioning at the location 24 hours a day, seven days a week. Longford was originally awarded the contract for works from the City of Albury.
The scope of the project included a trenchless pipe installation of 1.6 km of glass-fibre reinforced plastic (GRP) jacking pipe at a depth of up to 9 m and the construction of 38 sewer manholes, as well as the installation of 375 mm diameter ductile iron (DICL) DICL pipe for the open trench sections.
For the boring operations, Adept Civil chose to use a Vermeer axis guided laser boring system, chosen because of its laser feature that determines the line and grade of the bore, resulting in grade accuracy throughout the duration of the bore.
The closed-circuit camera built into the drill head allows the operator to constantly monitor line and grade, while the vacuum excavation method removes spoils efficiently without the need for manual labour. Additionally, the system’s modular design can be configured and modified in several ways to match any constraints imposed by the job site.
By employing a trenchless construction method for part of the project, operators have been able to protect the surrounding environment and cause less disruptions to businesses in the area. In particular, the trenchless portion of the project is taking place in close vicinity to a road with a significant and consistent level of traffic, so minimising disruption is extremely desirable.
With an expected total project length of 8 months, Adept Civil anticipates works will be completed in the second third of 2020.
