London-based international architect Aedas has launched a legal bid to win unpaid fees from troubled contracting giant Jarvis.
The practice is determined to force the firm to pay an outstanding undisclosed bill, which was first racked up on a private finance initiative (PFI) education project in Brighton in 2002 and 2003.
It has issued a writ in the High Court in an effort it hopes will force Jarvis to pay for the work the practice carried out.
Aedas' move comes as the culmination of a long-running campaign to win back the cash owed, that first saw it take the case to adjudication.
It is understood that the legal dispute centres on a £20.7 million PFI contract to extend and refurbish four schools for Brighton and Hove City Council.
The project saw extensive work carried out to Stringer High School, Patcham High School, Surrenden School and East Brighton College of Media Arts. A spokesman for the council said that it had been happy with the work carried out.
Aedas director Peter Oborn refused to comment on the case, except to confirm that his office had issued the writ against the contractor.
It is as yet unclear how many architectural practices are owed cash by the massive construction firm for other PFI jobs. Speculation is rife that if the company were to collapse then it would leave several architectural firms floundering with debts outstanding.
Concerns over Jarvis' future have continued over the festive period following news that the company has continued to sell assets in a desperate bid to stay afloat, including a property investment firm and its interests in the London Underground public-private partnerships.
Jarvis was unavailable for comment.
