§ Mr. Rookerasked the Secretary of State for the Environment if the PSA has yet completed remedial work on the six Ministry of Defence buildings found to be defective in the reinforced concrete due to excessive or improperly used calcium chloride; and if he will make a statement regarding the costs of this remedial work.
§ Mr. FreesonWork is not yet complete. The cost of the work ordered to date is approximately £91,000 and the estimated cost of that outstanding is approximately £142,000.
§ Mr. Rookerasked the Secretary of State for the Environment if his Department has discovered any buildings, other than the six Ministry of Defence building, in which corrosion of the reinforcement is considered to be caused by the excessive or improper use of calcium chloride.
§ Mr. FreesonEleven further buildings in the PSA estate have been identified in which calcium chloride is considered or is suspected of being the principal cause of corrosion of the reinforcement. No central record is held of damage which may have occurred to buildings in the private sector.
