Maintenance and Engineering ensures that airport buildings and installations are kept fully operational; it includes the internal equipment of the air terminal (e.g. baggage conveyor belts, moving stairways, passageways, heating and air conditioning systems, power supply) and the external equipment (e.g. runway lighting, instrument landing system, telecommunication and meteorological equipment), as well as airport vehicles (e.g. buses, firefighting and apron vehicles) and ground-handling equipment (ground power units, aircraft stairs, and cargo and baggage handling equipment).
Where engineering and construction services are performed by outside consultants or contractors at airports the in-house engineering section manages all their activities.
Engineering includes the definition of new projects and programmes, including preliminary and final project specifications. Where an Airport Master Plan is defined the engineering and maintenance will monitor close adherence to this plan.
