The company was appointed earlier this year in an effort by the council to resolve the many problems that had emerged on Grimshaw's high-profile project.
a defectively glazed glass wall;
substandard fire doors;
insecure steam room doors;
extensive leaking floors;
the use of galvanised steel that has started to rust;
paint peeling in the steam room;
incorrectly installed electrics and water ducts; and
cracks in the basement.
As this list was revealed, Bath & North East Somerset council was keen to stress that the spa would be open by its latest deadline in April 2006, despite the ongoing battle between contractor Mowlem, Grimshaw and the council itself.
Councillor Nicole O'Flaherty said: 'My first reaction was a mixture of concern and disappointment.
'However, I am assured by our contractors and officers that the implications of this list of works will have little or no bearing on the opening date of the project. These faults will be the subject of claims against those responsible.
'In view of the additional work that has now come to light, I find it inconceivable that the previous contractors would have been able to complete the building to everyone's satisfaction in the time they stated.'
