Contractors saw the number of contracts secured fall from 180 to 115, with the total value also plunging from £2.82bn to £1.25bn as fewer large contracts were also signed off by wary clients.

According to estimates by information specialist Glenigan, Interserve secured most work in April with a total haul of £83m.

Interserve’s work includes the final £23m package of an upgrade to the A602 and two jobs on the A609, worth £27m and £15m respectively.

The annualised leagues saw BAM take pole position, now closely challenged by Kier, Morgan Sindall, Willmott Dixon and Balfour Beatty in fifth place.
