Seismic upgrade

Seismic strengthening mibar wellington Wellington

Project Summary

Trademark was contracted to undertake seismic strengthening to one of Wellington’s iconic commercial heritage-listed buildings – the Mibar. Located on the corner of Victoria and Wakefield Streets, this 1950s modernist building with its wave-form canopy, curved glass windows, and decorative façade was home to the Lido Café for over 20 years.

Our teams worked on the curved section at the front of the building, which was identified as the area most at risk. The work was intensive and had to be completed in confined spaces – we couldn’t have anyone working down in the caissons, and we could only work on one concrete foundation and in one area at a time.

“The whole project was really bespoke. It was small but intense. One of our engineers described it as surgical strengthening.”

Each foundation had to be excavated and structural strengthening work completed, including using a combination of vacuum excavation and drilling. Due to the nature and size of the building, the work had to be completed by hand and using small machinery.

The high-profile location meant safety was a key consideration during the renovation for both the public and the delivery teams.

Project features:

  • Heritage-listed commercial building
