Duratec was engaged by Curtin University to perform repair works to building 201 which was constructed in 1967. The building consists of 7 levels with a terracotta tiled roof laid on timber battens. Air conditioning units are mounted on the roof.

The roof had deteriorated significantly over time as a consequence of poor construction and ambient factors. Historical roof leaks were occurring on regular basis due to cracked/damaged roof tiles, improper sarking installation, failed sarking joint and cracks in the copper gutters.
