Remedial work at Heathrow's Terminal 5 is exceeding its M&E budget by 拢56,000 an hour

Heathrow Terminal 5 was beset by problems this week as it emerged that remedial work was being carried out on the building鈥檚 roof and the project is exceeding its M&E budget by 拢56,000 an hour.

BAA originally estimated it would take 6 million man hours to complete M&E work on on the Richard Rogers Partnership (RRP) project. That figure was exceeded last month, which suggests that the 拢56,000 per hour required to pay for the project鈥檚 2,000 M&E workers and materials is outside the original budget.

The roof is also leaking, although BAA says the repairs fall under 鈥渞outine snagging work鈥�.

The client has denied that the project is over budget, despite admitting that the original man hours budget had been revised.

A BAA spokesperson said: 鈥淪ix million was a baseline figure estimated in 2002. Since then, the project has added to its scope, but it is not over budget. These sums are factored in.鈥�
