Two additional operating theatres, and a MRI scanner to increase surgical and diagnostic capacity, were installed at Forth Valley Royal Hospital as part of the NTC project and are already up and running.
A spokeswoman for NHS Forth Valley said: “Over the last few months, work has been undertaken with the contractor and NHS Assure to address the remaining outstanding technical issues relating to the pipework and fire compliance regulations.
“A potential solution has been submitted to building control for review and we are currently awaiting feedback.
“Once a solution has been approved and agreed by all parties, a detailed workplan will to be developed to take forward the required changes along with a timetable for the completion of this work.”
NHS Forth Valley said the project’s capital costs remain within the original estimated budget of around £10m.
