Rob Parker, Director at Grant Thornton said: “Due to the financial position of the business, unfortunately the UK business has ceased to trade with the vast majority of the 215 employees being made redundant.

“The Joint Administrators and their team will now concentrate their efforts on supporting employees through the Redundancy Payments Service claims process during this difficult time, as well as seeking to maximise realisations from the Company’s assets for the benefit of the creditors of the Company”.

A raft of suppliers and subcontractors working with Roadbridge are now left holding millions in unpaid invoices.

Roadbridge UK was working on two HS2 sites where hundreds of its staff were sent home last week.

The firm’s contracts on the project are understood to have been worth up to £60m.

The largest deal was in a joint venture with Tarmac working for main contractor EKFB (Eiffage, Kier, Ferrovial Construction and BAM Nuttall).

Roadbridge was also working on a smalller contractor as a subcontractor to the Align JV of Bouygues, Sir Robert McAlpine, and VolkerFitzpatrick.

One supplier said: “I’m owed more than £100,ooo so we’ll just have to wait and see what happens next.

“We were working with them on the Tarmac joint venture so hopefully Tarmac will pay our bills but we’ve heard nothing official from them or HS2.”
