Joinery specialist Swift Horsman has distanced itself from troubled concrete-frame contractor Swift Structures by announcing that the Halligan brothers, former owners of Swift Structures, are to resign from the board.

Swift Horsman directors have written to clients saying that the company, which is carrying out a £5m joinery contract at Portcullis House, is a separate entity from Swift Structures. The letter says the Halligans are non-executive directors.

It is understood that the Halligans have agreed to sell their stake to the directors of Swift Horsman.

At the same time, it has emerged that O’Rourke Group managing director Ray O’Rourke, who folded Swift just one week after acquiring it, bought the firm for £1 from the Halligans. The company is currently in administration.

O’Rourke Group this week moved in to take over a Swift contract for Kier on the £100m TAG McLaren headquarters near Woking, Surrey.

It has also taken over work on the Bovis Lend Lease-managed Touchwood Court. John Doyle is understood to be taking over Swift work on the £100m Merrill Lynch head office in the city of London.
