Antoun Civil was contracted by Sydney Airport to install and commission Centreline Airport Ground Lighting (AGL) on runway 16L/34R, which would enable use of the runway in low-visibility conditions.
This project involved approximately 5km of trenching works; including 2.5km of micro-trenching (100mm) for shallow base, pit and conduit installation; and up to 20km in total of electrical cabling.
Work was carried out during curfew hours in an operational airport environment while working around other critical electrical, data and communication services and existing AGL lighting services. Trench
excavation, placement of conduits and services, backfilling and reinstatement to a serviceable condition was complete by 5:00am each shift.
To complete the project efficiently and within curfew hours, the project team developed a system which saw Volumetric trucks placing concrete into a custom-made concrete hopper to place concrete into the 100mm trench. Utilising a rapid set concrete product meant that by the time concrete had finished being placed at one end of the trench, the concrete at the starting point had cured, enabling hot-mix asphalt to be delivered directly to the trench in a continuous work flow. This system saw the Antoun Civil project team achieve efficiency of more than double the nearest competitor; where other contractors were averaging 80m per night, the project team placed up to 210m in one night shift (150m-180m on average).
