Projects

Accurate surveying is essential when upgrading and maintaining complex rail yards. During a major rail renewal project in Western Australia’s Pilbara region, specialist survey teams supported the installation of new track, turnouts, and level crossings while ensuring the network could continue operating efficiently. Working across multiple work fronts and shutdown periods, surveyors provided the precise data needed to guide construction and maintain alignment with design requirements.

Survey responsibilities included establishing control, verifying design data, supporting turnout installation, and assisting tamping operations to achieve the required track geometry. Detailed surveying and modelling allowed construction teams to position track components accurately and respond to changing project conditions while maintaining safety and quality standards across the rail yard.

Advanced technologies also played a key role in project delivery. Drone surveys, digital modelling, and specialised rail software were used to capture site conditions, support alignment adjustments, and quickly respond to unexpected events within the network. These capabilities helped ensure works progressed efficiently while providing reliable survey data for rail construction and maintenance teams.
