Councillors met in Dumfries on Tuesday to discuss the findings set out by education director Colin Grant.
Leader Cllr Elaine Murray was shocked by his report, which reveals “fundamental flaws” found at the £17 million flagship centre, which opened in 2008 but had to close three years ago.
The list includes missing wall ties on DG One, corrosion to steel columns, ductwork installed incorrectly, drainage problems and replacement of stone cladding.
After a legal wrangle, the centre is undergoing repairs costing an estimated £10 million – but now it is likely that millions more will have to be spent on it
Other buildings locally, including the Ice Bowl at Dumfries and the Ryan Centre at Stranraer, are now being examined and at the Ice Bowl a number of issues have already been uncovered.
Dr Murray said: “The DG One building is an absolute disgrace.”
And members unanimously backed plans for a full scale inquiry into the debacle.
Meanwhile, minimal works are progressing onsite at this stage due to the extent of the further issues identified and the need for urgent consideration of the associated costs to address these new matters. A further report on costs will now be drawn up and is expected to be released in eight weeks.
