Earthworks and Civil Infrastructure

Reliable infrastructure relies on comprehensive planning, quality construction, and precise maintenance. Our highly-experienced team are capable of overseeing every aspect of civil infrastructure and earthworks projects, including storm water basins, pavement construction and guard rail installation. By reverse engineering projects we can make accurate predictions regarding cost, viability and time, and can formulate a plan to manage the often-complex task of dealing with planning departments and regulatory authorities. As a result, we’re consistently able to reduce total project costs, avoid lengthy delays, and produce solutions that fit their purpose and will stand the test of time.

Projects using Earthworks and Civil Infrastructure

Rangiora Aeration Basin

The Contract Works involved the construction of a new earth wastewater treatment aeration basin at the Rangiora Wastewater Treatment Plant (WWTP). The site was an active wastewater treatment plant and the contract works were carried out at the same time as other significant construction works to construct a new inlet pump station and screening channel.

Existing pipelines had to be protected and remain live throughout the period of the contract works. Temporary bypassing pumping and pipework was required to maintain a live network/plant.

Radcliffe Culvert Extension

 
This project involved the extension of the existing historical culvert while working around live traffic and preserving a historical arch. One of the biggest challenges to this was carrying out work with heavy plant, while maintaining a live road as this was the only heavy haulage route in and out of Lyttleton.

A new wastewater pump station was constructed in Kaiapoi. The project involved a 5.8m deep, 2.5m wetwell construction in a high water table environment within the Kaiapoi Red Zone. The construction method included an 8m deep sheetpiled cofferdam, wellpoint dewatering, PE pipe welding laying. All of this was done while working around existing services.

Ouruhia Radio Mast

Ouruhia Radio Mast Foundation Remediation

Following the September and February Canterbury Earthquakes, the 137m high radio mast foundations settled significantly and rotated. This was a consequence of lateral ground spreading and liquefaction.  The remedial work required stabilisation of the 48 tonne mast and re-tensioning of the guy rope system.

Mount Cook Sewage Treatment Pond Stage 2

This contract was undertaken by Hunter Civil during winter at the Mt Cook/Aoraki village. Weather conditions (particularly the heavy snow and constant freeze/thaw conditions) made this job very challenging at times. A large dumping of snow mid-way through the project added to the complexity and challenges we faced on the ground.
