Gully bridge lifts - March 2024
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 Gul
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
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

Protecting the Gullies
One standout objective of this project is the preservation of the environmentally sensitive gullies. These natural features play a vital role in the local ecosystem, and the team has approached their protection with innovative engineering solutions. By managing complex access requirements, applying innovative methodologies and constructing the steel network arch bridges without disturbing the gullies, the project exemplifies excellence in both design and environmental stewardship.
For the CB Civil team protecting the Gullies isn’t just a project element; it’s a commitment to safeguarding our natural heritage for generations to come.

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.
