Duration5 months
Bothar Boring & Tunnelling completed the microtunnelling of 610m of 1500mm diameter GRP jacking pipe in June 2018.  Launching from the very centre of Melbourne, Bothar successfully completed the challenging project from an extremely compact site setup in order to minimise disturbance to the public.  Tunnelling adjacent to Spencer Street - a main thoroughfare in central Melbourne - varying ground conditions including basalt, gravel and clay were experienced over the course of the drive.
