Elizabeth Quay

Contracted by Golder Associates, from December 2012 through to mid January 2013, Hagstrom Drilling utilised our landing barge - ‘Ocean Sampler’ with one of our Heliportable Rigs (DR010) to complete the site investigation.

Scope of work

  • Two over-water geotechnical boreholes, extending to depths of about 30 m or at least 5 m into rock, along the proposed jetty alignment, using PQ/HQ diamond drilling techniques
  • Two over-water geotechnical boreholes, extending to depths of about 20 m, along the proposed William Street Landing edge wall alignment, using PQ/HQ diamond drilling techniques.
  • Two over-water geotechnical boreholes, extending to depths of about 20 m, along the proposed Island edge wall alignment, using PQ/HQ diamond drilling techniques.
  • Standard penetration tests or U63 push tube in-situ testing will be conducted at approximately 1.5m intervals, or when advised by the onsite engineer, in soil or extremely low strength rock.
Ocean Sampler has the ability to be anchored in a given position utilising a four point anchoring system supported by a DGPS system to accurately position the barge over the borehole locations.

Our site investigation schedule was tailored to ensure minimal disruption to the marine activities in and around Barrack Street Jetty, and was completed on schedule and without incident.
