Project Name: Westmere Memorial Presbyterian Church
Client: The Presbyterian Church Property Trustees
EQ Struc utilised innovative retrofit methods such as near surface mounted (NSM) carbon fibre reinforced polymer (CFRP) strips embedded into masonry to improve the earthquake performance of the walls. In addition, new reinforced concrete columns were hidden inside the original rubble filled masonry buttresses and new timber trusses were constructed to replicate existing trusses. The project was completed in 2015 achieving a new earthquake rating of 67%NBS. The solution did not alter the external and internal appearance of the building, which was a key project objective.
- 67%NBS was achieved with a limited project budget and strict heritage requirements;
- The strengthening design was award the “Earthquake Strengthening Award - Best Project Under $1m” by New Zealand Society for Earthquake Engineering
