Tender Details
The Service Provider is required to undertake geophysical investigations comprising echo sounding and seismic reflection, refraction and magnetometer surveys in three areas of Sydney Harbour and to produce a total of two Geophysical Interpretative Reports (both with preliminary and final versions).
Three adjacent / close proximity areas in Sydney Harbour are to be investigated concurrently, in two costed packages, under one contract.
The Service Provider is responsible for the provision of geophysical investigations, testing and reporting. The aim of the investigation is to assess the geotechnical conditions including interpretation of sea bed profile, the underlying soil / rock profile and generalised soil / rock unit characteristics within the profile.
Marine geophysical investigations are required in order to provide a general characterisation along the alignments where the proposed route of the SRT may cross below Sydney Harbour. It is anticipated that the harbour consists of potentially deep palaeo-valleys that were filled with sediments. Information for this area is required to assess the geotechnical constraints which would have a major impact on alignment, design and construction methods.
The specific objective of the geophysical investigation is to provide information on the water depth, sediment thickness, and depth to the top of rock and the quality and strength of rock within the corridor as specified in the Services Brief to allow an assessment of issues for tunnelling.
Specialised equipment and experience are required.
