A meeting between the management company at Longboat Quay apartments and the Dublin Docklands Development Authority ended this evening without agreement.
An improved offer had been expected towards the cost of essential fire safety works.
In a statement, the management company said today's talks were disappointing and no meaningful advancement was made.
They say they intend to go to the commercial court on Monday to ask the court to accept its action against the DDDA on the commercial list.
Around 900 residents had been threatened with evacuation by the City Council unless work began on remedial repairs by the beginning of November, although this deadline was postponed due to legal proceedings.
The initial cost was estimated at €4m but this has now been revised to €3.88m.
The DDDA had originally offered €1.75m towards the costs on top of €1m already earmarked for upgrading the alarm system.
Residents had rejected the offer.
Two sets of legal proceedings are under way - a Circuit Court challenge to the fire safety notice and an action in the Commercial Court to force the DDDA to pay for the works.
