The Botany Rail Duplication (BRD) project involved duplication of 3 km of single-track rail line to create a double-track freight corridor between Mascot and Botany, improving rail capacity to Sydney Airport and Port Botany. Works included removal and replacement of two existing bridges with post-tensioned concrete structures spanning major intersections and motorways, including O’Riordan Street and the Southern Cross Drive Motorway.
Construction was completed under highly constrained urban conditions, requiring extensive planning, interface management, and staged weekend possessions to minimise disruption to road users and the freight network.
CaSE & Pike Design delivered specialist temporary works design and third-party independent design verification directly to John Holland and through subcontractors Freyssinet, Zoomwave, and Sarens.
CaSE Contractors seconded key engineering and project staff to John Holland’s team, supporting temporary works coordination, on-site engineering, environmental control, and validation of remedial action plans.
