The civil works were inclusive of bulk earthworks, piled retaining walls, in-ground FRP, external services infrastructure, site retention, road and public domain works.
Scope:
Bulk earthworks and disposal of 80,000m3+ of spoil
Construction of 120l/m contiguous piled retaining wall and capping beam to facilitate 10m bulk cut
Shotcreting of retaining wall in stages during bulk excavation
