Glenfield Junction Joint Venture

Project Description

Geo Image Services was contracted to provide surveying services for this prestigious government-initiated project that will provide essential infrastructure for south west Sydney’s growing population.

This project will provide a major link to employment hubs such as Liverpool, Parramatta and the Sydney CBD.

Geo Image Services’ dedicated survey manager collected data from the project team. This data was incorporated into the expanding ground model and design anomalies were detected prior to set out.

As the ground model was updated and issued each week in 12d, AutoCAD and MicroStation, designers consistently received the most current ground model, minimising duplications and delivering superior levels of accuracy throughout the project’s duration.

Efficient administration and planning procedures ensured resources were available and immediately deployed as required. Throughout the project Geo Image Services’ team of 40 specialised staff provided ongoing support to ensure the project was managed and executed effectively, within the allocated timeframe.
