Dunstans Construction Group has recently completed 2 HDD projects in the Otways National Park Victoria  for John Holland on the Colac Pipeline Replacement. The project involved one crossing 292 meters long and another at 340 meters long, 500mm HDPE PN16 was installed on both crossings. The project posed significant challenges whilst working in a class A nature reserve with daily sitings of Platypus. Dunstans also drilled to a depth of  30 meters below the surface encountering some very high strength rock. The project was a huge success.
