On this aviation project Careys undertook testing on existing concrete foundations at Heathrow Airport to check their suitability to support new, larger airbridges that would service A380 aircraft. The foundations were located on live aircraft stands, two of which had airbridges operating on them. Following these tests, our contract was extended to include the breakout and rebuilding of nine rotunda bases located on different stands through a phased programme, enabling the construction of new airbridges.
