Viotel - monitoring Auckland's heritage buildings

Viotel - monitoring Auckland's heritage buildings

The structural health of the Leys Institute, some of Auckland's important heritage buildings, is being monitored in real-time by Viotel using our SMART IoT technology. The historic building has experienced some structural cracking due to ground movement over its 115-year life.

The twin buildings are home to the Leys Institute Library and Gymnasium. A recently completed seismic assessment has found structural issues that make the buildings unsafe to occupy in the unlikely event of an earthquake.

Consulting engineers GHD were engaged to undertake structural assessment of the building and utilised Viotel's IoT technology to provide continuous real-time monitoring of movements across several the more critical cracks in the structure.

Viotel's real-time monitoring system provides a web interface dashboard that provides crack meter response in terms of absolutes values, trend rate of movement and a heat map type indicator plot of criticality of movement.

Earthquake-prone buildings

In 2017, new earthquake-prone legislation was introduced by the New Zealand government.

Auckland is categorised as a low seismic risk area meaning Auckland Council is only required to identify buildings as potentially earthquake- prone that are unreinforced masonry buildings or built before 1976. The law requires building owners, including Auckland Council, to make identified earthquake-prone buildings compliant within a 35-year time period. For heritage buildings, this stretches to 45 years.

Auckland Council has been undertaking detailed seismic risk assessments of council's portfolio of around 2500 buildings and structures across the region. To date it has completed around 350 assessments and expects to have the remainder completed by 2021.

The Leys Institute was closed to public access in December 2019. Auckland Council will be considering options to restore Leys Institute and make it safe and fit for purpose.
