Caulfield – Dandenong Level Crossing Removal Project

Tetra Tech Coffey provided geotechnical, hydrogeological and contamination assessment advice to inform the final design, and provided ongoing advice through out construction of the elevated rail solution.

Project Description

The Caulfield to Dandenong Level Crossing Removal Project was established to remove nine of Melbourne’s most congested level crossings along the Caulfield to Dandenong rail corridor. Project scope included:

  • Completely rebuild five train stations.
  • Lengthening of 30 existing station platforms.
  • Installation of new signalling and power systems to support new high-capacity trains, affording a 42% capacity increase (equivalent to around 20,000 passengers a day).

Scope of works:

Tetra Tech provided geotechnical, hydrogeological and contamination assessment advice throughout the tender, which informed the final design of an elevated rail solution. We were further engaged throughout design and construction in providing detailed geotechnical investigations, geotechnical design of foundations, on site verification of ground conditions, assessment and interpretation of soil and groundwater contamination including close liaison with the Victorian EPA.

Services provided in support of the project include:

  • Geotechnical design advice for tender submission, leading to final design of raised rail solution.
  • Detailed geotechnical investigations for factual report and geotechnical design of foundations for initial part of the alignment and subsequent construction phase services.
  • Contamination assessment and groundwater inflow modelling during tender services.
  • Detailed contamination investigation, assessment and interpretation for project delivery, including close liaison with the Victorian EPA on sustainable and efficient spoil management approaches.
