Construction chiefs have written to chancellor George Osborne urging him to approve the expansion of Heathrow Airport to boost the building industry.
Thirteen bosses signed a letter asking Osborne to give the green light for the long-awaited third runway project.
The government was initially due to decide how best to tackle the air capacity crisis in the South East by the end of 2015, but has since delayed a decision until this summer.
Now construction leaders including Balfour Beatty chief executive Leo Quinn and Bam Nuttall chief executive Stephen Fox have written to Osborne, who said in his spending review speech last autumn: “We choose to build”.
“We are writing to encourage your support for Heathrow expansion,” said the letter. “Heathrow is one of the biggest private developers in the UK, having invested around £11bn over the last 10 years.
“Heathrow expansion will bring with it a £15.6bn order book to the UK supply chain. Heathrow’s new plan will also make it the most sustainable hub airport and Britain the best connected country in the world.
”The government’s Airports Commission gave its clear and unanimous backing last summer. Let us help you build a better Britain by expanding Heathrow.”
