Scope of Works
The scope of works involved the supply and installation of 36 metres of DN600 mild steel enveloper pipe in two bores and 18 metres of DN900 from one large launch pit at different grades and alignments, facilitating the installation and connection of DN375 & DN600 SCL pipes. The works consisted of setting up the auger boring equipment at three separate settings from one launch pit. UEA used the McLaughlin auger boring machine with a specially designed tungsten carbide tipped drill head to install the steel enveloper pipes. Ground conditions were consistent with Sydney sandstone with some harder iron stone deposits.
The project was a success, with UEA completing all bores on the correct grade and alignment and then completing the project within one week of commencement.
