Drew Crossley is a Principal Civil Design Engineer based in Brisbane with more than 18 years of experience focused on designing mine and surface-water infrastructure, specifically geomembrane-lined ponds.
For the coal-seam-gas sector, Drew designs and constructs large multilayered concentrated brine ponds. Related work includes site inspections, concept design and optimisation, and preliminary and detailed design, along with construction support and certification. He also handles annual inspections of these ponds, prioritising and developing maintenance plans, designing upgrades, and certifying completed works.
Drew also offers experience with drainage systems, ponds, culverts, reinforced earth gabion walls, general mine site earthworks, waste dumps, and heap leach pads, and he manages large projects, including the overall civil design elements for copper, gold, and coal mines in Indonesia. His surface-water experience has included hydrology, hydraulics, and water-balance modelling used in the development of design packages.
