In Activity 1, we try to answer the question how, where and when pipes fail in a network. Therefore, prediction of pipe failure is central considering internal/external factors. Pressures induced by traffic and ground can have substantial contribution to overall factors that cause pipe failure. In order to examine the behaviour of pipe due to these loadings, field instrumentation is undertaken in Sydney Water (SW) test pipe bed at Strathfield, Sydney Australia. The test pipe is a decommissioned spun cast iron pipe with a diameter of 660 mm , installed in 1922.
