Evacuation strategy: Stay put 

Your building operates a ‘stay put’ policy. When a fire occurs within your flat, you should alert others in the flat if the alarm has not already sounded, make your way out of the building and call the fire and rescue service. 

If a fire starts in the communal area, anyone in these areas makes their way out of the building and summons the fire and rescue service. All other residents not directly affected by the fire would be expected to ‘stay put’ and remain in their flat unless they become affected by the fire or are directed to leave by the fire and rescue service.

There is manually openable casement windows provided within the stairway and the adjacent flat entrance lobby on each of the upper-floor levels within the building. A permanent vent is provided at the head of the stairway. The flat entrance lobbies on the upper floors have a mechanical ventilation shaft with fixed louvre style grilles provided within each of the lobbies. The ventilation shaft appears to discharge via ducting, through the roof space direct to open-air.

There is a sprinkler system which covers the bin store area only.

Within flats assessed, it was generally noted that Grade D LD3 AFD systems were provided, however, in some cases the detector had been removed by residents, and in most cases no heat detectors were present within kitchen areas, these have been Identified as remedial actions.

A BS 5839-1 L5 detection and alarm system is installed within the communal areas, with detection being fitted within the ground floor communal areas, service/plant rooms, ventilation shaft, roof void and within the residential lobbies on each level. As this is a high-rise property, Riverside have taken the action to minimise the risk using the L5 system as this is a building which possesses exceptional hazards due to its size and proximity to other buildings. L5 detection added to stairwells. Not linked to AOVs as these are manual opening (due to be upgraded 2025). Alarm sounders in communal areas not linked to an ARC system.

Building description
A purpose-built, high-rise, residential building of twenty-five floors, comprising of 145, individual, self-contained, scissor section flats/maisonettes. Flat 1a is accessed on the ground floor. Flats 1-6 are located on the first floor of the building. Flats 7- 18 are located on the third-floor, flats 19-30 are located on the fifth floor. There are twelve flats per floor, located on floors seven to twenty-one. (Odd numbers only). Flats 127-144 are located on the twenty-third floor. The building has a single stairway separated at each upper-floor level by a lift lobby with a bin chute room containing a wet rising main & a separate maintenance/storeroom. Secure common area fire doors give access to the flat entrance corridors each of which contains automatic smoke ventilation and emergency lighting. Smoke ventilation is provided at the head of the stairs along with manually opening windows on each half landing. The ground-floor entrance lobby gives lobby protected access to flat 1a and the electric cupboards as well as to the lift lobby and stairwell. Manual controls for the AOV system are located within the communal entrance lobby. An externally accessed plant room and integral communal bin store is located at ground floor level. A security/concierge/staff office is located within the ground-floor communal entrance hallway.  

Construction type
The basement floor is likely to be suspended reinforced concrete slab supported on deep piled foundation, considering the height of the building.   

The building structure comprised reinforced concrete floor slabs supported onto reinforced concrete columns and walls with external cladding façade panels. From the limited internal access to the flats, we assume that the floor flat slabs were supported on reinforced concrete columns and walls and lift shaft walls in the block.   

As the frame is formed of reinforced concrete the robustness requirements of tying elements together for disproportionate collapse are generally complied with by following general detailing methods and the design codes.   

The overall stability of the structure is likely provided by shear walls around the stair and lift cores centrally with the slabs acting as diaphragms to transfer lateral forces back to these elements.   

The roof of the building is of a reinforced concrete slab and the communal staircases and landings are of reinforced concrete construction. The roof structure appeared to be steel frame supported onto the reinforced concrete slab.

Floor construction type
Concrete

Stair construction type and details
Kelson House is a single stair building. The stair also serves as a firefighting stair with a stair width of 1100mm in line with the current 1100mm minimum width for a firefighting stair.  

A separate tower contains lifts, escape-stairs and other services, and is linked to the main block by bridges leading to the access-corridors. The building has a single concrete stairway separated at each upper-floor level by a lift lobby with a bin chute room containing a wet rising main & a separate maintenance/storeroom. Smoke ventilation is provided at the head of the stairs along with manually opening windows on each half landing.  

External wall systems
The EWS1 rating of this building is A, no remedial works required as risk of external fire spread is low.  

PRP’s site observations identified the facade as 110mm aggregate-concrete panels with no cavity or insulation. The concrete slabs and structural concrete walls provide fire breaks between compartmentations. Rockwool SP Fire Stop vertical cavity barrier was observed at the front of structural concrete walls between windows at vertical compartment lines.   

Remediation works were completed in 2020 on the staircase. The wall structure and cladding system was replaced, the new system does not include combustible materials.  

The investigation did not identify combustible materials in the external walls, there is no need for remediation work to be undertaken to the external walls of the specified attachments. 

Height of uppermost occupied story

Flood risk

Fire prevention measures
There is a BS5839-1 category L5 automatic fire detection system within the common areas of the building which is provided for control of the smoke ventilation system only. This comprises a fire detection system control panel and smoke detection throughout the common area. Manual call points and fire alarm sounders are not provided. 

There is no sprinkler suppression system installed within the building.  

A sprinkler system is not required for the refuse room at the base of the refuse chute, as there are no more than two flats opening off the protected escape routes on each level. Only the first-floor chute is not enclosed in a separate enclosure to the access lobby/escape route. This is considered acceptable as there is no lift present in the access lobby and the Flats in the residential corridor on this floor have alternate means of escape.

Evacuation strategy: Stay-put 

The residential areas of the properties operate a ‘stay put’ evacuation procedure. That is, in the event of a fire in a flat, the occupants of that dwelling will evacuate, having been alerted by their own domestic fire detection and alarm system, and request fire service attendance. All other occupants will remain in their flat unless they are threatened by fire and smoke or are advised to evacuate by the fire service.

Evacuation strategy: Stay-put 

The residential areas of the properties operate a ‘stay put’ evacuation procedure. That is, in the event of a fire in a flat, the occupants of that dwelling will evacuate, having been alerted by their own domestic fire detection and alarm system, and request fire service attendance. All other occupants will remain in their flat unless they are threatened by fire and smoke or are advised to evacuate by the fire service.

Evacuation strategy
This building was designed to utilise, and should, operate a ‘stay put’ evacuation strategy. A ‘stay put’ policy involves the following approach, as outlined in Approved Document B 2022; When a fire occurs within a flat, the occupants alert others in the flat if the alarm has not already sounded, make their way out of the building and summon the fire and rescue service. If a fire starts in the common parts, anyone in these areas makes their way out of the building and summons the fire and rescue service. All other residents not directly affected by the fire would be expected to ‘stay put’ and remain in their flat unless they become affected by the fire, are directed to leave by the fire and rescue service or choose to leave. Any ancillary spaces, although individual rooms, effectively operate a simultaneous evacuation strategy where any occupants would evacuate the space upon discovering or becoming aware of a fire.
