Service Locating and Potholing, Torrens Road To Torrens River (T2T) Project

A significant component of the North-South Corridor programme is the Torrens Road to River Torrens Project, which delivered a 4km non-stop roadway with sections of lowered motorway up to 8 metres below the existing road surface.

As part of the T2T preliminary design phase DRASOL were engaged directly by DPTI to carry out extensive service locating and potholing on a 4.8km stretch of the major road corridor. The entire package was conducted out-of- hours with stringent guidelines and time constraints on access to the work zones.

DRASOL self-performed these works, which involved the provision of the following services:

  • Community liaison and stakeholder engagement
  • Management of night works access and environmental plans
  • Coordination of utility providers attendance, inspection and network access permits
  • Traffic management plans, approvals and implementation
  • GPS survey, data capture and reporting
  • Service locating
  • Hydro-vac excavation and pavement reinstatement
  • Rock beaching and matting • Swale drains
  • Pavement reinstatement

Our team was responsible for the real-time capture of GPS survey data and photographic records, which were regularly submitted to the client design team as a project deliverable.

The accuracy and clarity of the reporting was critical to facilitate the design process and in this respect DPTI’s expectations were far exceeded.
