The scope also covers the widening of six engineering structures, two new railway structures, retaining structures, slope stabilisation, tunnel rehabilitation, road reinstatements, station alterations, substations, affected utilities, fencing and expropriations. Quadrante’s engineering work focused on hydrology, platform drainage, railway and road structures, retaining structures, tunnel rehabilitation, road reinstatements, fencing and expropriations.
