Project Description

The objective of the Southwell School dining room project was to provide seismic strengthening to one of the oldest buildings on their campus, where the building held huge sentimental value but had a very poor earthquake rating and no real visible strength. This process was conducted from start to finish while students were on holiday. We maintained the look of the building while developing structural strength where the bricks had been made by the pupils, the concrete frame was probably built by a working bee going back to the original Southwell School, and the timber roof just didn't have enough structure to meet the current codes.

On either end of the building were two original fireplaces which were not structurally sound, therefore we needed to strengthen these. It looks as good today as it did before we started, so you've got to be looking very carefully to spot the strengthening. We have also developed the background knowledge required to advise clients around whether or not they should invest in a building needing earthquake strengthening – measuring the overall cost of purchasing and strengthening a building against the estimated value of the restored building.
