Bulk Earthworks – Retaining Walls
Underground Services – Roadworks
RJV commenced construction at Rosehill Waters in August 2016, starting with bulk earthworks on what was previously a public golf course. Initial works involved removal of nearly 15km of underground reticulation pipework (much of it asbestos), together with remediation and backfill of existing ornamental lakes. Existing MRWA drainage installed through the golf course had to be realigned onto the new road layout via 1050mm diameter pipework at 7 metre depth. Given the close proximity of the Helena River strict sediment control measures were required to prevent turbidity in the Helena River.
Civil works followed the forward earthworks package, with stage 1 incorporating approximately 170 lots and including 20,000m2 of road pavements, plus 400 metres of sewer slurry microtunnelling under existing roads and sensitive watercourses.
RJV is currently constructing the second phase of earthworks and two further civils stages.
