Heathrow Terminal 4 was built at a cost of £200 million and opened by the Prince and Princess of Wales on 1 April 1986

Following an overhaul of existing and the installation of new sky bridges we were contracted to install sealant to the perimeter of the inset panels which made up the walls of the bridges. This application was carried out internally as well as externally with the use of a scissor lift. All works were Air-side and completed out of hours.
