Guernsey's Public Services Department (PSD) has vowed to continue to dispute more than £30m overspend claims made by contractors on two major projects.
The dispute involves contracts for St Sampson's marina and the new St Peter Port jetty.
A £3.3m estimate for the jetty was changed to an open-ended budget in 2003 when it was found to be in a worse condition than at first thought.
Contractors are claiming £27m. Claims for the marina total more than £7m.
The States said it would continue to contest both claims.
A £7m overspend on the island's airport redevelopment has been resolved.
