Local government officers believe there will be a great deal more litigation between the council, the sacked contractor, Mowlem, and possibly the architect, Grimshaw.
The Spa Claims Management Group (SCMG) was set up to safeguard the council's position.
The project finally opened earlier this month, both over budget and over five years behind schedule. It was the source of a huge row over who was to blame.
Eventually, architectural and engineering consultancy Capita Symonds was brought in to complete the project alongside Grimshaw.
Despite the completion, council officers clearly believe there is more legal action to come - however, it won't give details of the SCMG's work.
But a source said: 'The purpose of the Spa Claims Management Project is to ensure the council is in a position to negotiate and defend any claims that may be made by third parties against it, and for the council to bring any claims for costs incurred in respect of poor design and/or workmanship issues.'
