UEA Trenchless has completed construction of a vital crossing as a part of a major infrastructure upgrade for a Sydney power authority in inner West Sydney. The project is preventative and has been scheduled to meet the requirement of replacing key cables supplying power to Sydney’s inner western suburbs before they become unreliable.
UEA Trenchless has successfully reached the revised half way point of transfer main installation works and is well on the way to having the directional drilling works for the PSP Appin Wastewater Scheme completed on time. Further to the contract works awarded earlier this year UEA has been asked to undertake an additional 2,006 metres of directional drilling due to changes in design requirements as well as several areas of environmental sensitivity.
Installation of the transfer main pipeline as part of the Appin Wastewater Scheme is almost complete with UEA successfully pulling in the final directional bore in early February 2012.
UEA has been successful in its bid for the first of a number of trenchless crossing packages for water and sewer pipelines on a $100m capital works project in North West Sydney. The project is being delivered through a recognised national construction company in a design and construct arrangement.
UEA Trenchless has recently completed directional drilling works on the Cowan Wastewater Scheme which will see a 3.4 km pipeline built along the Pacific Highway to the existing system at Berowra, creating a pressure sewerage system (PSS) reticulation network for the community of Cowan NSW.
Not all trenchless techniques and technology are created equal. Each has its own set of benefits and drawbacks and selecting the right method for the job is an important part of the planning process for trenchless contractors.
