UEA Trenchless Division commences Cable Infrastructure Reconstruction Project – Beaumont NSW

Posted 14 October 2014

In June 2014 UEA Trenchless Division commenced works on a significant Horizontal Directional Drilling (HDD) project at Moss Vale Road at Beaumont, a town adjacent to the tourist destination Kangaroo Valley in the Illawarra region of New South Wales.  The original design of the underground installation consisted of conduits approximately 680m in length, broken up into two under bores with lengths of 480m and 200m, and a short section of overhead cable connecting the two under bores.

UEA mobilised to site and commenced both under bores concurrently; the shorter bore using the all-terrain 40/20 drill rig and the longer bore the Vermeer D100 x 120 drill rig.

The shorter bore constructed as per the design with no issues within the programmed duration.3-Route Alignment of Short Bore 1

During the pilot for the longer bore it became apparent that due to ground conditions the bore could not be constructed as per the original design. UEA stopped works and in consultation with the client came up with an alternate design.

This alternate design consisted of increasing the length of the bore by moving the drill rig 50m further down the hill, allowing the bore to be at a constant positive grade. The revised design allowed the bore to be completed successfully through problematic conditions.

Even though the challenging ground conditions encountered on the longer bore caused a delay with a new design being required, UEA completed the project within the programmed duration.
