Christchurch water treatment pond pipe replacement

The Christchurch earthquakes badly damaged the Christchurch Wastewater Treatment Plant, its oxidation ponds and its pipes. The earthquakes cracked pipe walls, allowing other liquids and obstructions such as groundwater and liquefaction silt in. Some wastewater pipe sections completely collapsed and all joints leaked, which meant wastewater was released into the surrounding area.

As a result new pipes connecting oxidation ponds 2 and 3 at the water treatment pond needed to be installed.

ACG College Tauranga

Waiariki Health and Sciences Building

In 2013, Hawkins was engaged to construct the multi-million-dollar Health and Science Centre, part of the rejuvenation of the Mokoia Campus.

 

Waiariki Institute of Technology’s aims:

Te Atatu Library and Community Centre

In 2006, Auckland Council began working on plans for a new library and community centre in Te Atatu. The existing facility was small and only had a limited selection of books and the community centre was run down. As a result, the Council decided to demolish the existing building and to build a new one on the same site with good connections to neighbouring Jack Pringle park. We were awarded the construction contract through a tender process in 2013.

 

Auckland Council’s aims:

Ruataniwha Kaiapoi Civic Centre

Waimakariri District Council’s aims: 

  • To replace the old library with an enhanced facility
  • To upgrade the adjacent section of Raven Quay to create a shared space environment for vehicles, cycles and pedestrians.

What we did:

Ahuroa Gas Storage

In 2007, Australian-based Origin Energy bought the Ahuroa gas field (east of Stratford in Taranaki) from Swift Energy. The intention was to build New Zealand’s first underground natural gas storage facility. As part of the deal, Contact paid for the right to own and operate Ahuroa as the underground storage facility and to buy the remaining gas and LPG reserves in the Ahuroa reservoir.

Project Gemini Data Centre

In late 2013, Telecom (now Spark Digital) took the opportunity to construct one of the largest, most sophisticated data centres in the world in the Auckland suburb of Takanini. This would provide clients with state of the art security for their data within a building that is tsunami and earthquake resilient.

Spark’s goals:

Novotel Hotel, Christchurch

In May 2012 repairs to the 14-storey hotel began. Everyone agreed that infrastructure was a major priority and vital to attracting visitors back into the city. A little over a year later, it was complete.

 

Accor’s Goals:

  • To reinstate the hotel back to its original condition
  • To strengthen the seismic standard to meet the new building code.

What we did:

Ibis Hotel, Christchurch

Accor’s Goals:

  • To reinstate the hotel back to its original condition
  • To strengthen the seismic standard to meet the new building code

What we did:

The first step was to enter the building and assess the damage caused by the earthquake as well as to carry out some initial emergency repairs to support the building against any aftershocks.

Citygate (PwC Centre)

In response to this growth and in a quest to make Hamilton a more liveable city, Hamilton City Council has initiated a number of infrastructure development programmes. The Citygate building was one of these.
