The $157.4 million move to a new super-sized headquarters for the Super City could cost ratepayers a further $10 million to demolish the Civic Building.
About 2400 council staff will begin moving into the 31-storey ASB Tower at 135 Albert St in early 2014, which senior officers say will save $101.8 million over 20 years and make better use of staff time.
But a confidential report on the big move, released to the Herald by the council, reveals the scale of the problems plaguing the Civic Building, including an estimated cost of $10 million to demolish it.
The 19-storey Civic Building is riddled with asbestos in service areas, ducts and around the external facade, beams and columns and the glass and aluminium entrance is corroding from water damage.
