Bulk Lamp Change — Aircraft Ground Lighting (AGL)
Estimating, Cost Planning, Quantity Surveying
Project overview
Coordinated modernisation maintaining approach and landing guidance.
Regulatory bulk lamp replacement across AGL systems to maintain consistent light output and replace aging lamp technology. Aircraft Ground Lighting systems comprise thousands of lighting units installed across the airfield — approach lights, runway lights, taxiway lights and obstacle lights.
These lights guide aircraft during approach, landing, takeoff and taxiing operations, particularly in low visibility conditions. Aviation regulations require periodic bulk replacement of lamps — both to maintain consistent light output and to replace aging technology with more efficient alternatives such as LED upgrades.
This coordinated bulk lamp change campaign across multiple AGL systems required careful planning to minimize airfield disruption, specialized knowledge of AGL systems, and compliance with aviation safety standards throughout. Quant Measur managed the commercial and cost aspects, coordinating specialist contractors.
