DURATION: 2018 - 2023 
CLIENT: NAPIER CENTRAL FIRE STATION

THE BRIEF
Strata Group took on the significant task of executing a seismic upgrade for Napier’s Central Fire Station, aiming to elevate its earthquake rating from 15% NBS (IL4) to an impressive 67% NBS (IL4).

THE SOLUTION
The project’s complexity heightened due to the necessity for the facility to remain operational post-earthquake. Further complicating matter was the site’s location, bordered by open waterways on two sides, leading to an expected lateral spread of around 2 metres during extreme seismic events.

Strata provided detailed structural drawings and calculations, securing the building consent for the seismic upgrade. The technical aspects involved the replacement of URM (Unreinforced Masonry) infill with lightweight timber frame walls. Additionally, structural strengthening techniques were applied to the appliance bay roof bracing and office spaces. Foundation tie beams played a crucial role, connecting two wings to mitigate damage from lateral spreading. 

THE OUTCOME
The seismic upgrade project for Napier’s Central Fire Station exemplifies Strata Group’s commitment to delivering innovative and resilient solutions to our clients. By overcoming significant challenges and leveraging diverse expertise, we successfully elevated the earthquake rating of the facility, ensuring its continued functionality and safety in the face of seismic events.
