Structural engineers

Structural advice on building design that is robust, pragmatic, and economic.

Seismic and structural integrity form the basis of any good building. We’ll work to protect your property, ensuring it’s strong enough to withstand environmental challenges.

From heritage to new builds

Prendos structural engineers dare to tread where others won't, in tackling technically complex structural engineering projects on a range of commercial building types. We can work with you as a standalone service, or in conjunction with our in-house team of architects and professional quantity surveyors.

Cutting-edge seismic resistance systems

Earthquakes in New Zealand since 2011 have driven the use of innovative structural strengthening designs that incorporate new seismic resisting systems. Our team has pioneered seismic systems that meet the upgraded risk across the country. Trust us to determine the level of seismic resilience required, and help you implement low damage systems that increase seismic resilience.


It’s confusing if you’re not in the industry. We start with an initial seismic assessment (ISA) that provides qualitative insight into whether your building is earthquake-prone. If it is, we advance to a detailed seismic assessment (DSA) based on drawings, council records, measurements taken during site investigations and concrete scanning. Today’s minimum requirement is a new building standard (NBS) of 34%. A building with a high NBS is a highly marketable investment, but it’s also important to understand a low NBS when you’re planning future improvements.
