ABSTRACT
The Metro Tunnel Project will deliver twin 9 km rail tunnels from Kensington to South Yarra as part of a new end-to-end Sunshine to Dandenong rail line in Melbourne. In addition to the tunnels, five new underground stations will be constructed. Town Hall station will be located at the southern end of Melbourne’s CBD. The station will be constructed within excavated shafts, mined caverns and adits (underground passenger connections). The excavations are bordered by a range of buildings including a number of heritage listed structures. This paper outlines the approach taken to assess ground movement impacts on the buildings, describes the instrumentation installed to monitor building movements during construction and compares some of the predicted and measured movements.
