AbstractThe Peace Tower, built between 1919-27, is a 92 metre (302 ft) high campanile at the main entrance to the Canadian Houses of Parliament in Ottawa. By 1990, the exterior masonry had deteriorated and cracked. This resulted in a major masonry conservation project, completed in 1996, which included re-pointing, stone repair, grouting and improved water-shedding details. A comprehensive monitoring program was subsequently commissioned to monitor hygrothermal performance and structural movement. The main objective is to evaluate the long-term performance of the tower and, in particular, the impact of the conservation work on the behaviour of the composite masonry concrete exterior walls under varying environmental conditions. Data from the monitoring provides a greater understanding of in-service behaviour and provides input for analytical modelling. The program also provides an early warning system to facilitate an effective maintenance program. This paper describes the monitoring program and presents some of the results.
