Some of our customers

We are breaking new ground in establishing such a dense network of seismic monitoring in an urban environment. It is going to change the Christchurch narrative from one of seismic risk to one of seismic resilience.   What we learned from the Canterbury earthquakes is that there is huge variability in the ground shaking experienced. Proximity to the source of the quake, the direction of the ground shaking and local ground conditions causes significant variability in ground shaking across the city. Our initiative with CSI has created an affordable model that encourages uptake by public agencies and commercial users alike.  The benefits that we’ll gain, in terms of minimising disruption after an event, protecting our buildings and people, and building our resilience, are huge.

Smart Christchurch

It is extremely important to our customers and the wider business and social communities for us to safely recommence operations as quickly as possible, but we don't do that until we've got a really good understanding of what the size of the event was and what it means for our different assets. Access to time history data that we and our advisers can use as inputs into structural and geotechnical models is critical to this process.

An educated decision rather than an emotional response.

They're really easy to deal with, they explained the whole process all the way through and actually specified the system that works really well for our unique establishment.
