The staff were notified by email that they were to be made redundant yesterday.
Hill was hit be the uprising in Libya where its UK project management arm was working on 25 university projects. Since then the 43 staff operating from the London office have been gradually wound down.
Eric Butterworth, vice president and managing director of UK project management, who also lost his job yesterday, said: “Clearly this is very disappointing and is a reflection of the economic conditions in Libya and the UK.”
Hill International called on Butterworth to set up the project management and cost consultancy business more than four years ago.
This saw Hill buy project management company John Shreevers & Partners to give it critical mass in the UK.
John Paolin, spokesman for Hill International, said: “We have movement in our staff on an ongoing bases depending on when projects start and end. This is that nature of our business globally.
In the UK, Hill operates mainly as a claims business, and Hill International stressed that no office would be closed as a result of the decision to lay off the UK project management team.
