Abstract

Topographic, geophysical, geotechnical and soil contamination survey of:

(a) 4.3 ha converter station site; and

(b) 1.4 km x 20-55m wide underground HVAC cable corridor with total survey area of 4.3 ha. The overall survey area is 8.6 ha.

The survey comprises:

• topographic survey;

• buried utilities investigation;

• geophysical survey;

• geotechnical survey, including location-specific UXO surveys prior to any excavations;

• in-situ and field testing;

• geotechnical sampling;

• soil contamination sampling;

• tank base concrete coring.

The non-intrusive surveys comprise GPS RTK and/or conventional land survey methods, drone aerial mapping techniques, seismic refraction (30 m target penetration), Ground Penetrating Radar (GPR), electrical resistivity measurements and thermal resistivity measurements.

The intrusive surveys comprise 10 boreholes (30 m depth), 14 trial pits (3 m depth), 14 dynamic probes (10 m/30 m depth), 6 slit trenches (2.5 m depth) and 24 concrete cores (3 m depth).

Disturbed and undisturbed samples will be collected from boreholes and trial pits for laboratory testing for a range of geotechnical parameters and soil contaminants.
