The Christchurch Town Hall is acclaimed worldwide for both its architecture and acoustics. Its position at the centre of the new Performing Arts precinct reinforces its status as a premier event space and the project won the IStructE Supreme Award and Heritage Award at the 2021 Structural Awards.
Due to the land damage caused by the 2010 and 2011 earthquakes, the Town Hall foundations required strengthening and damage repair to the original design. Maintaining the original identity of the building was integral to this project with a desire for a tangible link to ‘pre-quake Christchurch’.
With significant portions being upgraded, repaired, and restored, and additional areas undergoing a complete rebuild, this project offered the full spectrum of structural and geotechnical challenges. Holmes Consulting undertook this technically complex conversation project totalling to approximately NZ $167million.
