Sydney Metro - Northwest
In June 2016 Meadows Consulting was engaged to assist the Joint Venture Partners John Holland Pty Ltd and CPB Contractors Pty Ltd on the Sydney Metro – Northwest Project.
Our engagement was to provide surveying services in relation to Track and Overhead Wiring construction on the project. The project involved the construction of 23km of new track, fixed track and also ballasted track. The conversion of 13km of existing track between Epping and Chatswood and the construction of 8 new railway stations, namely Tallawong Road, Rouse Hill, Kellyville, Bella Vista, Norwest, Showground, Castle Hill and Cherrybrook.
The project was estimated to cost $3.7 billion and was completed in 2019. Meadows Consulting Pty Ltd is pleased and proud to have been engaged on such a high profile, unique project within the greater Sydney Trains metropolitan area.
