Boral’s largest hard rock quarry development in Australia, the Boral Peppertree Quarry is in Marulan South, in the NSW Southern Tablelands region.
PSM was engaged to complete geotechnical investigations and prepare designs and specifications for the plant site, the rail embankment, a water storage dam and associated spillway feeding into twin 4 m diameter corrugated steel pipes through the rail embankment. PSM was also asked to maintain a geotechnical site presence during construction.
Keeping costs down and minimising rehandling of material were key considerations of this project. Engineering and technical opportunities included:
Following a rigorous assessment and modelling, PSM’s tailored approach included:
As the principal consultant, PSM planned and executed a targeted geotechnical site investigation at a reduced cost. An experienced contractor successfully implemented the design within the expected timeframe and with no ongoing contract claims at completion of the works. PSM’s presence on site during construction allowed the design to be optimised and was certified completed in accordance with the design.
