Saffron Square

FDS Provides Complete Fire Safety Solution For Saffron Square

When Berkeley Homes (South East London) constructed its modern development Saffron Square, Fire Design Solutions (FDS) was able to design, supply and install a compliant and effective solution.

Situated in the heart of Croydon, Berkeley Homes’ Saffron Square development offers contemporary residential apartments, convenient transport links into London and landscaped rooftop gardens.

Standing 43 storeys tall, the tower has an impressive presence on the Croydon skyline, and this height required significant expertise to provide an appropriate level of fire safety in accordance with Building Regulations and Local Authority.

Appointed directly by M&E contractor A&J Ryan Mechanical Services Ltd, FDS designed and supplied mechanical smoke ventilation and corridor environmental systems, as well as a complete installation and commissioning service. The works for this project were completed in August 2017.

Computational Fluid Dynamics (CFD) Modelling

The specialist team at FDS were responsible for the creation of the system drawings and the use of Computational Fluid Dynamics (CFD) Modelling. The drawings showed the elements being installed, while the CFD models illustrated the ways in which they would affect the movement of heat and smoke in the event of a fire.

Mechanical Smoke Ventilation

Due to the scale of Saffron Square, mechanical smoke ventilation systems were recommended, as they offer greater efficiency over natural smoke ventilation systems. The system consists of a mechanical extract shaft, which is connected to a fan mounted at roof level, with fire dampers on each floor.

The mechanical smoke ventilation system activates automatically if smoke is detected, clearing common corridors of smoke. Crucially, this allows occupants to evacuate safely when instructed by the fire services and clear access for emergency services.

Berkeley Homes (South East London) constructed a single 1m2 smoke shaft that serves all 43 floors into which FDS fitted a louvered damper at each level. An Automatic Opening Vent (AOV) door was also installed on the 1st floor to supply air in the event of a fire, with an AOV window on each floor from the 2nd to 43rd storey.

Finally, with smoke ventilation systems, regular inspection and maintenance is as important as the initial installation and commissioning. FDS’ expert team has also been awarded the contract to carry out ongoing service and planned preventative maintenance to ensure optimal operation in the event of a fire.

Fire Design Solutions King of the Urban Jungle with Lyon Square Appointment

Award-winning smoke ventilation contractor Fire Design Solutions (FDS) has been appointed to provide its systems and expertise for a distinctive new London residential development, from Redrow Homes.

Once complete, Harrow’s Lyon Square will feature over 300 one, two and three-bedroom luxury apartments with direct access to the City, plus a courtyard, underground parking and cycle store.

The appointment will see FDS supply, install and commission Mechanical Smoke Ventilation Systems (MSVS) in eight of the development’s blocks, ensuring that smoke can be quickly extracted from common areas in the event of a fire, providing a means of escape for occupants while also improving access for attending fire fighters.

The MSVS will incorporate a Corridor Environmental System, which will use the existing fans and shafts found in the mechanical systems to remove excess heat during day-to-day operation. To maximise resident comfort, the environmental system will operate at low speed overnight, and acoustic silencers will be fitted to the inlet and outlet of each smoke fan, ensuring that noise is minimised.

The whole system will be monitored via an addressable Corridor Smoke Detection System, including optical smoke detectors, a central concierge panel and sprinkler monitoring, which will feature in two of the development’s blocks.

In addition, FDS has been appointed to supply, install and commission a Thrust Ventilation System for the development’s 3,330m2 single-level car parking area, including induction fans, carbon monoxide (CO) detectors, fire detection systems and a control panel. As well as clearing smoke in the event of a fire, the induction fans will also operate when CO levels exceed 30 parts per million, ensuring the safety of the car park’s users.

Once work on site is complete, FDS will also ensure that the fire safety systems installed are maintained to the highest possible standard, carrying out two maintenance visits per year and providing a 24-hour call-out service.

Speaking on the project, Simon Halfhide, Sales Director at Redrow Homes said: “Harrow is a vibrant, character-filled area, and Lyon Square will make an excellent addition to the area.


“Having worked with FDS in the past we’re confident in their abilities to maximise fire safety while also helping us to meet our design aims.”

Nick Waterfield, Managing Director of Fire Design Solutions added: “By providing and installing our mechanical and environmental smoke ventilation systems we can ensure that the development will not only be safe, but comfortable for its residents.”

First completions at The Lyon Square development are due June 2017.

Located in the capital’s most exciting new commercial quarter, the 25-storey Stratford Plaza development in Stratford, East London, boasts 220 impressive one, two and three bedroom apartments across 20 floors. As well as its close links to the city centre and the Queen Elizabeth Olympic Park, the development also benefits from 2,000m² of commercial office space within its first five floors.

Stratford PlazaAppointed to the project by property developers Telford Homes, FDS designed, supplied, installed and commissioned mechanical smoke ventilation systems for the mixed use development. By keeping staircases and common corridors free from smoke in the event of a fire, the ventilation system will provide a safe escape route for residents, while also allowing access for fire fighters.

Having reviewed the building’s design, FDS installed a corridor environmental system, which utilises the mechanical smoke ventilation system to provide day-to-day ventilation in order to prevent overheating in its corridors.

By making use of the existing mechanical system, costs were minimised, while also reducing the system’s impact on the space available in the building.

As well as managing temperatures, the environmental system will revert to fire safety mode in the event of a fire, ventilating smoke and returning the corridors to tenable conditions.

Along with the office and residential space, FDS was also tasked with installing an enhanced car park ventilation system for the development’s three levels of car parking space.

Through the use of Computational Fluid Dynamics (CFD) Modelling, FDS was able to demonstrate the effectiveness of the car park ventilation system, which will exhaust unwanted pollutants from vehicles, and provide smoke clearance in the event of fire, maximising safety for the occupants.

The Stratford Plaza development was completed in November 2014, while its car park was completed in March 2015.

The benefits of Mechanical smoke venting systems to those who occupy the buildings are clear: In the event of a fire, mechanical ventilation systems offer excellent smoke control, removing smoke from the building to aid the occupants’ means of escape, improve visibility and provide clear access for firefighting services.

However, the benefits extend way beyond safety. What are the business reasons installing mechanical systems as opposed to natural smoke ventilation? We’ve put together the following infographic to demonstrate the many economic advantages of MSVS.
