Christchurch Town Hall Repair

Christchurch City Council

Following damage from the 2011 earthquakes, the Christchurch Town Hall required significant refurbishment and seismic remediation. This heritage listed building is of special significance to the people and the city of Christchurch and is one of the biggest heritage/conservation projects undertaken in Christchurch.

The project included the installation of circa 1,100 jet grout piles beneath the floors and foundations which retard lateral spread of the soil beneath the structures and 5,400 cu metres of heavily reinforced concrete slabs and columns were constructed with some 67 tonnes of reinforcement.

Octa had a two-person full time presence on site for much of the project, taking the Project Manager and Supervisor role under the NEC 3 form of contract.

The main auditorium has been restored and strengthened to 100% NBS and a new purpose-built facility was constructed for the Christchurch Symphony Orchestra (CSO), giving it a permanent home in the complex for the first time.

The Limes Room building was supported on temporary works while columns were broken out and jacks installed to enable re-levelling of the structure. Once completed, the loads were transferred back to the temporary works and the old columns demolished and re cast - once again taking the load.

The project was administered using the Christchurch City Council collaboration tool, Conject. This is a web-based system used for the storage, retrieval, distribution and review of all contract documents as well as being structured to enable the administration of NEC processes.

The three-year contract ended on schedule with the official opening taking place on 23 February 2019.
