The photo was taken without the knowledge of main contractor Skanska during construction of the 755ft tower.
Worker Michael Crompton told The Sun how he persuaded 11 colleagues to sit across a steel girder to eat their lunch.
The snap recreates the famous “Lunch Atop a Skyscraper” photograph taken during construction of New York’s Rockerfeller Centre in 1932.
Crompton said: “We changed it slightly — one of the workers had a can of cider in our shot, while in the original they had a bottle of whisky. And underneath our coats we all have harnesses and lanyards.
“But it was almost minus 10°C out there on the 48th floor and a few of the lads were telling me to hurry up.”
