project information
Overview
The M1 Pacific Motorway extension to Raymond Terrace addresses the last major missing link on the east coast motorway corridor between Sydney and Brisbane. The southern section — delivered by the John Holland Gamuda Australia Joint Venture for TfNSW — covers 10 kilometres of new dual-carriageway motorway between Black Hill and Tomago, including a 2.6-kilometre viaduct spanning the Hunter River floodplain, the Main North Rail Line and the New England Highway. The project delivers eight bridges and new interchanges at Black Hill, Tarro and Tomago, removing up to 25,000 vehicles per day from key congestion and merge points. Jointly funded by the Australian and NSW governments at a total program cost of $2.1 billion, the extension is expected to open to traffic in mid-2028, reducing peak-period travel times by up to nine minutes.
RCS Scope
Road & Civil Surveys provides survey support for the John Holland Gamuda JV on the southern section, with 1–2 surveyors deployed on site. Scope covers earthworks set-out and as-built surveys, pavement and road set-out, drainage and utilities infrastructure, and interchange construction works at Black Hill, Tarro and Tomago. RCS supports the project control network and provides data calculations and EOM reporting. Night shift and road closure coverage supports live traffic interfaces where the new motorway ties into the existing M1 and surrounding road network.
Value Driven
The M12RT engagement continues the John Holland relationship established on Port Botany Rail and carried through the AWRC, M7–M12 and Beerburrum to Nambour — with RCS now supporting John Holland across multiple concurrent major projects. Providing reliable supplementary survey capability on one of the Hunter region’s largest-ever infrastructure projects ensures the JV has consistent coverage across the civil works program without resourcing gaps during peak construction periods. Night shift execution at live traffic interfaces on the existing M1 corridor — one of the highest-volume routes in the Hunter — demands disciplined, accurate survey practice under pressure.
