Mary raised the question :
Not so long ago, Heathrow was constantly under construction. Builders encroaching on taxiways, big jets edging round tight corners.
How many times did this result in a wingbender, I wonder? and if not a lot, how was it prevented?
To clarify, some of this work was the reconstructing of the taxiways to provide Code F (A380) clearances - some areas are still to be done.
A lot of planning is carried out to clearly define work areas and, if necessary, taxiway block closures based on aircraft wingtip clearances/jet blast areas. This ensures that both aircraft and construction workers are safe from each other and I'm unaware of any incidents where the two have met.
