4.2: BUILDING REGULATIONS: PART

All information reffered to in the diagram to the right is taken from Approved Document B Volume 2 unless otherwise stated. (HM Government, 2022)

The size and complexity of the floor plans of this building means that it will require an automatic fire detection system. This system will be primarily concerned with the protection of life as opposed to property. Despite the public nature of this building, a phased exit strategy would not be appropriate. The installation of an automated system would also eliminate the reliance on manual systems or staff operated systems. This would vary across the different types of spaces in the building so as to best prepare for the consequences of a fire in each specific space.

The systems installed across the building would be: L3 – systems designed to warn of fire at an early enough stage to enable all occupants, other than possibly those in the room where the fire started, to escape safely before the escape routes become impassable because of fire, smoke or toxic gases. – in compliance with BS 58391.

The fire detection method would vary across the building to suit the spaces:

• Most single story, contained spaces (e.g. offices and studio spaces) would be fitted with a point heat system

The fire detection method would vary across the building to suit the spaces:

• The larger atria would have to be fitted with a Aspirating Fire Detection system as the high ceiling heights would rule out the effectiveness of a point heat system

• Most single story, contained spaces (e.g. offices and studio spaces) would be fitted with a point heat system

• The larger atria would have to be fitted with a Aspirating Fire Detection system as the high ceiling heights would rule out the effectiveness of a point heat system shaped building on blandford square. been sufficent space left for a refuge - the core would have to redesigned.

• The plant room would be fitted with an infrared early fire detection system alongside a high-pressure mist system that would be capable of effectively suppressing a fire from the large pieces of machinery etc.

The LVL frame structure will naturally char and build a layer around it that will protect it from fire. As this material is consistent and has a predictable char ratethe beams can be oversixed to give a suitable fire proof time of 120 minutes - this will be sufficient time to allow for evacuation and arrival of the firefighting team.

(Office/shop and direction) meets the width requirement of 4 storeys with less than 270 a simultaneous evacuation

There has not been sufficent space left for a wheelchair refuge - the core would have to be redesigned.
