Project Name: Ground Based Augmentation System
Location: Sydney Airport
Client: Honeywell Aerospace / Airservices Australia
Civilcraft, in association with Honeywell, were contracted by Airservices Australia to carry out upgrade and replacement works on the Sydney Ground Based Augmentation System (GBAS) system located at the Southern end of the main runway at Sydney Airport. The works involved replacing four RSMU receiving antennae and the VHF VDB antenna array. Civilcraft carried out civil and site works relating to this upgrade.
As the works were conducted adjacent to a live runway, a high level or coordination was required to ensure no disruption occurred to plane movements in and out of Sydney Airport.

- Removal of six existing “ACO Cablemate” Pits
- Supply, installation and connection of conduits to new Class C specified pits
- Raising of pits within Ground Reflection Mitigation Zone to new proposed surface levels
- Removal of frangible posts and rope barrier
- Raising of existing plastic earth pits
- Supply and lay weed mat
- Excavation and preparation of base for new kerb
- Construction of 25MPa concrete ‘Kerb Only’ barrier
