To ask the Scottish Executive, further to the answer to question S1W-33681 by Margaret Curran on 21 February 2003, when the affected properties in the Ainslie Road and Macclehose Road area of the Cumbernauld and Kilsyth constituency were constructed; what each of the identified defects in construction was, detailing the effect each defect had on the property concerned, and on what date the legislation that prohibited the practices that formerly allowed each process now considered as defective was introduced.
Our understanding is that the properties in question were built in the 1960s.
Details of the defects and their impact on the relevant properties are set out in reports by A.J. Balfour & Associates, dated October 2000 and the Structural Partnership, dated August 2001. Copies of each are available in the Parliament's Reference Centre (Bib. numbers 27050 and 27052).
Advice and guidance on building practice, relating to the use of calcium chloride as an additive to accelerate the hardening of concrete, is contained in the British Standards Institution Codes of Practice. The 1977 amendment to Code of Practice 110 strongly recommended that calcium chloride should never be added to pre-stressed, reinforced concrete or concrete containing embedded metal. Code of Practice 110 was revised in 1985 and re-issued as Code of Practice 8110, which reiterated the previous advice.
