RIBA Responds to Approved Document B

EVIDENCE has been submitted by The Royal Institute of British Architects (RIBA) to the Government’s technical consultation on Approved Document B.

The document covers English building regulation guidance on fire safety matters within and around buildings.

In its response, RIBA has reiterated its key recommendations for minimum prescriptive requirements to provide clarity for industry:

• Sprinklers – a requirement for sprinklers/automatic fire suppression systems to be provided in all new and converted residential buildings (as already required in Wales), and installed in existing residential buildings above 18m whenever significant refurbishment or alteration work is carried out.
• Alternative means of escape – in new multiple occupancy residential buildings, a requirement for a minimum of two staircases, offering alternative means of escape, where the top floor is more than 11m above ground level or more than three storeys above the ground level storey (as required for commercial buildings).
• Centrally addressable fire alarms – systems for all new and converted multiple occupancy residential buildings and in existing residential buildings above 18m whenever significant refurbishment or alteration work is carried out.

Approved Document B

The architects’ body has expressed concern that the technical guidance in Approved Document B has been developed assuming that measures to resist the spread of fire will be effective and that the ‘stay put’ policy is reliable.  As the Grenfell Tower tragedy illustrates, if a fire spreads rapidly, a reliance on the ‘stay put’ policy can be devastating.

RIBA is calling for at least two staircases in new multiple occupancy residential buildings, as is already required in offices and hotels, and will soon be required in Scotland.  Sprinklers are already a requirement in Wales and this issue is of growing concern to the industry and the public.

Jane Duncan, Chair of the Expert Advisory Group on Fire Safety

Jane Duncan, Chair of the Expert Advisory Group on Fire Safety says: “We simply cannot allow buildings to continue to be built to regulations and guidance that everyone, including the government, acknowledges are deeply flawed.  Twenty months on from the Grenfell Tower tragedy, to continue with more consultation but not enough action, fails the public and does not honour the victims of the Grenfell Tower tragedy.”

“All residents should have the right to the added protection offered by sprinkler systems, to know if a fire breaks out in their building, and to be safely evacuated if necessary. This means the guidance must change to ensure a better warning system and an alternative means of escape.”
