Replacement Doors.

[Mike North]

I have 6 Identical large dinners; the latest building has FD30S double swing doors between the diner and kitchen the rest have FD60S.  All were built to 2007 regs. The doors are now at the end of life, can I replace them with

·         The regulatory requirement is for a FD30 door to be installed.

·         An FD60 rated door (as installed in 5 of the diners) configure as an FD30 to provide a more robust solution.

·         All double doors are to installed with

• A back-check mechanism to stop the over extension of the hinge on opening.
• Automatic hold-open connected to the fire alarm system with a timed release so that the doors return to the closed position when the diner is unoccupied.  

·         Door protection on both faces of the door to a height of 25mm above the height of the kitchen trollies.

·         The glazing with any associated beading shall not be installed within 25mm of the door protection.  

·         Leading edge protection shall be installed.

Did you conduct the FRA or are you the RP or acting for the RP.

[Mike North]

No FRA, it is a design change which will need to be approved by BC and FA

[Tom Sutton]

I think what you are proposing sounds reasonable but reducing 60 minute protection to 30 minute protection may need building regs approval you should consult with building control.

And you should have a Fire Risk Assessment in any case and a significant change, such as altering the standard of fire protection, requires a review. Building Regulations and Fire Regulations are totally separate entities.

Follow guidance BS 8214:2016 Timber-based fire door assemblies - Code of practice https://shop.bsigroup.com/ProductDetail/?pid=000000000030332501 with regard to specification of door assembly components.

I think that I am happy enough now to add an amendment to all 5 fire strategy reports and present these to the appropriate BC and FA for review and approval.
