Engaged by Worley Parsons and operating on the proposed BHP Hunt Point Tug Harbour site, the following components where completed for the project;
Setup of Site Facilities
A laydown area was setup on site which included a cyclone proof independent office, lunch and toilet facilities for the duration of the project.
Total of 11 boreholes were completed at onshore and intertidal ranging from 5-40 metres, a combined total depth of 299.40 metres. Marsh buggy drilled holes as far out as 250m from the shore line and was able to leave casing in the ground and move between position depending on the tide.
CPTu testing where completed at 39 locations on the Access Road, intertidal and onshore facilities to a nominal test depth of 20 metres bgl. This was completed using a combination of our track mounted morooka based CPT unit and a stand alone CPTunit based on our Marsh Buggy.
Excavation of 12 test pits at the Onshore facilities to a depth of 3 metres or refusal was completed.
Environmental GeoProbe Drilling
A Geoprobe drilling program comprised of the installation of 7 shallow groundwater monitoring wells to a nominal depth of 8 metres bgl plus the installation of 7 deep groundwater monitoring wells to a nominal depth of 18 metres bgl and the advancement of 30 soil bores using a direct push method to a maximum depth of 4 metres bgl.
