In 2006 further construction took place for the new Pier 6, built specifically to accommodate the new Airbus A380 superjumbo. At a height of 24.1m, the A380 is higher than four double decker buses stacked on top of each other.We were appointed by contractors Target Site Services to freeze the hot and cold water mains to enable isolation valves to be cut in. In order to get the hot water cold and non-flowing, we had to carry out a line stop to the 28mm copper hot water return pipework, located in T3 arrivals.Working in a riser in an office, we bolted

on a line-stop tee, then carried out an inflated balloon line-stop. Having stopped the hot water circulation, the pipework was able to cool down sufficiently to be able to freeze the pipe and carry out the pipe work modifications, crimping in new isolation valves, giving control of the area downstream from the new valves.We were able to carry out the whole process within 5 hours, on schedule and enabling Target Site Services to continue with their works.

Terminal 3 at Heathrow handles over 19 million passengers a year to long-haul destinations. First built in 1961 and expanded in 1970, the terminal then underwent extensive refurbishment between 1987 and 1990.
