Case Study

Tiger Brennan Drive Extension

Location: Palmerston, Northern Territory

Value: $110 million

Year: 2008–2010

Brief Description

The Tiger Brennan Drive Extension opened a key access corridor between Palmerston and Darwin. This new road was constructed across undeveloped land from Berrimah Road to the Stuart Highway. The project aimed to enhance freight capacity and improve corridor capacity between Darwin and Palmerston and rural areas by providing a direct link to the port.

FYFE's Responsibility

The works were executed in two stages. Stage 1 included 7.5km of dual carriageway highway to extend Tiger Brennan Drive from Berrimah Road to the Stuart Highway. To enable this land to be opened for construction, Fyfe played a key role in redefining cadastral boundaries for road creation. To open land for a new road to be built, fyfe provided consultancy from initial survey plan search, locating marks in the field to re-establish existing tenure, through to applying for lot numbers and pegging the newly created road boundaries.

Stage 2 consisted of a grade separated interchange at the Stuart Highway/Roystonea Avenue intersection with Tiger Brennan Drive. Fyfe conducted all engineering set out for the entire length of the new road alignment. Much of this road construction was built utilising machine guidance technology. Fyfe’s surveying staff became the “data custodians” for this job and were responsible for maintaining the construction design database for upload to plant.

The principle contractor’s scope of works included clearing, drainage and bulk earthworks, road pavement construction, sealing and asphalting, the construction of three bridges and provision of bicycle and pedestrian paths. They also carried out irrigation and landscaping and supplied all lighting, signs, safety barriers and other road furniture. Relocation of affected public utility plant, realignment and relocation of existing service roads and rail level crossings were also completed. Additional survey tasks that Fyfe conducted included survey of the location of ground testing boreholes, set-out of services, landscape levels and volumes.

The project employed about 200 people, with a focus on maximising Indigenous employment and business opportunities. Fyfe have continued to support indigenous engagement, and today have in place an indigenous engagement policy and indigenous trainee surveyors.

Tiger Brennan Drive officially opened to traffic on December 20, 2010. The project was completed on time and within budget and won the 2011 Civil Contractors Federation NT Earth Award for projects over $75M.

This project underlined the importance of effective and reliable support services. Whilst survey consultancy is does not constitute a large proportion of overall resources in large scale civil projects, fyfe’s involvement in this project showcased how delivery of professional and dependable survey assisted this project to be completed on time and to a high standard of works.

Project Technologies and resources utilised for Survey during this project:

  • Trimble machine guidance GPS for bulk earthworks
  • Trimble machine guidance Robitic stations for mm pavement levels
  • GNSS GPS for stocklpiles, vegetation clearing and similar works
  • Robotic total stations for precise engineer set out
  • Digiat levels for mm accurate construction levels
  • AutoCad drating for as constructed plans
  • TerraModel CAD software for day to day construction set out calculations.
