Multiple teams and various machineries work concurrently during the construction of a runway
Building a runway is a monumental project. The Runway 3 upgrading works, for example, involves 27 kilometres of pavement works for the runway and associated taxiways. The site is thus spilt into more than 100 zones to allow multiple teams to work on the various parts concurrently. At its peak, it can involve up to 2,000 workers, with more than 10 types of machineries used for works like excavation, piling, paving, rolling, and compacting etc.
4. Light's up!
At night, airfield lights along the runways and taxiways help pilots navigate their way around the airfield.
When the future three-runway system is in place, there will be about 20,000 airfield lights in Changi’s airfield. These are made up of more than 20 types of airfield lights, in different colours and combinations, each serving a different function. For example, some are designated to light up the runways and taxiways, and some are specially tailored at the touch down zone to aid pilots in landing, while some are traffic control and guidance lights.
5. Cleared for landing?
Finally, before the runway can be cleared for operations, flight checks involving live aircraft landing and taking off from the runway need to be carried out. This test ensures that all related systems, such as the airfield lighting system and the instrument landing system, are functioning well. In the case of Runway 3, one week will be scheduled for the flight checks, which will test both day and night conditions, for each direction.
