existing ground levelNew South Wales, Sydney, Australia - WestConnex is a motorway of more than 30 kilometres, built in three stages linking Sydney’s west with its international gateways and key places of business. It connects Sydney’s M4 and M5 motorways with the city, airport and Port Botany, and includes capacity improvements on existing roads and substantial new sections of motorway. A key part of this is the Parramatta Road Ventilation Facility (PRVF)

Due to the location of the PRVF, innovative solutions were needed to reduce noise output and ensure the impact on the densely-populated community was minimal. To achieve this, a unique shape for the shaft was developed, including three intersecting circular shafts that are each approximately 30m in diameter, to fit on the constrained site at the intersection of Parramatta Road and Wattle Street. Also, most of the PRVF building will be constructed below ground to minimise operational noise.
Key highlights of the project include:
Arcadis were appointed to provide civil design services for the WestConnex New M4 project in a joint venture with AECOM. As well as the design of the excavation retention system for the PRVF, Arcadis and AECOM delivered geometric and road engineering designs, pavement design, flood assessment and drainage design, traffic engineering services, lighting design, utilities coordination and structural design of the bridges, retaining walls, cut and cover tunnels and buildings.
