Base-isolation retrofit of the Christchurch Art Gallery enhancing seismic resilience and protecting valuable art collections, executed by Ruamoko Solutions and Fulton Hogan, resulting in a prestigious award-winning project.
The base-isolation retrofit of the iconic Christchurch Art Gallery building was an inspiring and technically challenging project with a highly successful outcome. The retrofit of 140 triple friction-pendulum base-isolators returned the seismic strength of the gallery to current building code levels without the need for any strengthening of the superstructure, and provided increased protection for its precious contents to reinstate the national and international reputation of the Christchurch Art Gallery.
Ruamoko Solutions was engaged by Fulton Hogan for their design-build tender on this project and carried out detailed structural design to completion. This required the analysis of the ground floor and basement structure to identify areas where structural strengthening and intervention work was required to meet the demands of the new isolators. The implementation of these devices required bespoke and innovative solutions to strengthen existing columns and retrofit supporting structure for floors, beams, walls, ramps, lifts and stairwells in the basement.
The project was on time and to budget to deliver one of the safest and most quake resilient galleries in the world to a delighted client. The project won a number of awards, including a silver award at the 2016 ACENZ Innovate NZ Awards.
