Option C – High-level remediation (preferred option)
This option is preferred as it delivers the safest and most resilient solution for the Central Library building. This means that further closures due to earthquake damage or additional strengthening won’t be required. Although the initial strengthening work is expensive it removes future costs arising due to earthquake damage or strengthening requirements (if building regulations change). It also increases the building’s life expectancy more than the other remediation options. This option delivers service continuity for the Central Library service, future proofs our ability to deliver an adaptable modern library service and explore partnerships. It also allows us to mitigate some climate change impacts in the future. The building’s heritage will be retained, and it will integrate more with Te Ngākau Civic Precinct and the surrounding streets through additional entrances, views, landscaping and improved accessibility.
Under this option the building’s structural issues would be mitigated to the highest extent possible. It includes work from the low and mid-range remediation options, plus it base isolates the building. Base isolation would mean the building would likely be safe to occupy during and after a significant earthquake, meaning it is most likely to be open afterwards. This option involves the most intrusive construction work and therefore creates the opportunity to fully upgrade the building and immediate surrounds, including connections to Te Ngākau Civic Precinct and Harris Street, and modernise how it works as a library, community and public space for the long term.
