In 2013 Ryebridge worked on the installation of a new Airfield Ground Lighting (AGL) system at London Luton Airport for Inviron, since taken over by European technical services provider Imtech. The team were involved in this project from the very first stages, tasked with producing the civil design elements. Once these were signed off and of course shown to be CAA compliant Ryebridge then constructed the pits and just over 4,000m of ducting in the airside environment. It also performed the slot-cutting and sealing work, again to CAA standards.
