Question
To ask the Scottish Government, further to any conversations that it has had with the wider sector, what its current understanding is of any risks associated with PAS 9980 as a methodology for fire risk appraisal of external wall and cladding construction in the context of the current ban on combustible façade materials in Scotland.
Answer
As part of the preparation of the SBA (Single Building Assessment process) Scottish Government has had conversations with the wider sector, including Fire Engineers and Assessors where we have discussed the need for a FRAEW (Fire Risk Appraisal of External Wall).
When assessing an existing building’s EWS (External wall system), it is noted that existing buildings cannot be expected to meet modern Building Regulation standards for risk to human life as these buildings were built during a time when less onerous Building Regulations were in force. The PAS 9980 will be used by assessors to make an informed expert decision of whether or not the EWS is a low, medium or high risk and dictate from this whether or not the current build up is tolerable, and no further remediation is required, or the risk is intolerable and therefore remediation should be undertaken.
The aim of a SBA is not to bring a building into compliance with current Building Regulations, but to ensure that the risk to building occupants is reduced to a tolerable level. The focus of the remediation is to follow the recommendations in the SBA in how to bring the relevant parts of the building to either a low, or tolerable risk level. Where large areas of the façade are being remediated, alterations will be required to comply with current (fire) building regulations including the use of acceptable materials. To note that the current ban applies to any new building warrant applications only.
