NG Bailey is lowering into place the first of 14 prefabricated modules at Heathrow airport's Terminal 5 to supply all low temperature hot and cold water and domestic services to the new terminal.
The four core risers being erected at Heathrow are commissioned by Carillion and manufactured by Bailey Off-Site.
Each of the four core risers are 25m tall with a 24m
2 footprint. They will house all main ductwork runs.
The company says the use of off-site manufacturing has resulted in a lot of time being saved - four months per riser, when compared with traditional methods.
