Hampton Downs Motorsport Park

Contract Value: $21 million
Client: GP Farms Ltd
Location: Hampton Downs, Waikato 

Ross Reid Contractors were the main contractors and the project was initially tendered as preload works for a value of $4.7 million. The client was satisfied with our performance on the project and involved us on a partnership basis for future stages of the project. The milestone for the client was to complete the infrastructure works for the apartments and complete the racetrack, which we achieved within time and agreed budget.

The project works involved land development of over 160 hectares. This includes reclamation of over 35 hectares of swamp land.

Project Scope:

  • Earthworks – about 750,000m3 of cut to fill (structural), 200,000m3 of cut to waste, topsoiling of 60,000m3, high strength geotextile about 250,000m2, 22,000m of subsoil drains. Settlement monitoring was carried out right through the project and maximum measured settlement was about 1m.
  • Water supply and waste water treatment plant.
  • Pavement – 110000 m2 of pavement construction with membrane seal and asphalting; of this, 51,000m2 was race track construction.
  • Twin road tunnel and pedestrian tunnel.

Ross Reid Contractors were involved in certain design and value engineering aspects of the project.

Pavement Design

Ross Reid Contractors provided an alternative pavement design solution which enabled the project works to continue through winter. Stabilising the subgrade under the track as well as the car parks and internal roads reduced the pavement depth and reduced subgrade improvement works significantly. This was also a cost saving to the client.

Tunnel Construction

The tunnel was located between the apartments and involved significant earthworks and retaining wall construction. Relocating the road underpass tunnel from beside the pedestrian tunnel to the end of the front straight saved the client on volume of excavation required, as well as batter stabilisation and therefore costs, but more importantly increased the usable car parking and pit paddock areas.
