Southern Gullies - Bikes on Pipes

Our client, Hamilton City Council, recognised the pace that the city was growing and the to develop new neighbourhoods and communities for future Hamiltonians. By 2035, HCC expect Hamilton to increase by more than 50,000 people which means the city will need at least 18,000 new homes. Peacocke is one of Hamilton's largest greenfield areas and the third area to be developed after Rototuna and Rotokauri.

This project is an extended separable portion under our Peacocke contract which has seen CB Civil continue to deliver strategic water and wastewater infrastructure, as well as new transport accessways to establish a strong connection to the surrounding suburbs. CB Civil have completed extensive bulk earthworks requiring deep excavation in complex rail and road corridors, developing the land for pedestrian traffic, the associated bridges and a 1200m gravity rising wastewater pipeline.

The Southern Gullies project seamlessly blends infrastructure, environmental consciousness, and community well-being. The wastewater network, SUP investment, bridges, and emergency storage tank embody a proactive approach to preparing  futureproof and resilient infrastructure to realise HCC's long-term vision. As we pedal forward, we’re not just building pipes; we’re weaving connections and safeguarding the land we call home.

As part of the project the Waikato regional team are delivering:

2 x 66m Single Span Bridges: To link the different Peacockes development areas the project has seen two NZ leading 'super lifts' in the launch of the ~100T bridges, all completed by the giant Liebherr 550T crawler crane to avoid any need to enter the Gullies.

Bikes on Pipes (on Bridges): The asphalt shared user path running alongside the wastewater pipeline and across the bridges has earned the project its catchy name. This path encourages cycling and walking, promoting sustainable transportation options while also connecting the Peacocke development to the greater Hamilton wastewater network through innovative, consolidated and creative engineering. How many projects deliver three major forms of public benefits in one go!

Active Transport Corridor: Over 1.4 kilometers of new shared user path will give active transport opportunities throughout the future Peacockes development. This vital connection will facilitate smoother traffic flow, benefiting residents, commuters, and businesses alike. 

Environmental Stewardship: The project prioritizes environmental conservation due to the sensitive ecological area for the scope of works. Construction has focused on ensuring minimal disruption to the fauna and flora of the surrounding environment. This has included extensive bat surveys and lizard monitoring throughout works.
