NSW Government utility locations survey

Sydney Gateway Professional Services Rail Duplication & Services Investigation

Case study

Client: RMS

Timing: 2018

Value: $1.2M

Services: 150

Background & scope

As part of the road upgrades and rail duplication project in the Sydney Gateway Project area, Infraworks were consulted by the NSW Government to play a key role in the production of a 3D (SUI quality level ‘A’) utility locations survey.

This involved locating and surveying the underground services at 150 localities, performed through NDD Potholing and positive location of services. 

Our approach

Infraworks took on the role of ‘principal contractor’, with the Infraworks project management team responsible for the development and implementation of all safe systems of work and coordination of project activities. 

To best prepare for the challenging conditions of each location, Infraworks performed an evaluation and subsequently grouped each location into respective categories based on safety requirements and type of utility.

With the evaluation complete, the planning and coordination phase began. This phase took into special consideration the availability of the service owner’s representatives, Rail Track possessions and ROL’s (Road Occupancy Licences). 

Clear communication and coordination of activities with the service owners was crucial to the success of the project. Infraworks worked closely with key parties to ensure each service owner was notified in advance of the works planned near their assets and all required approvals were sought in order to stay on schedule.
