Langham Square

Located in East Putney, St James Group’s mixed-use development, Langham Square, is the first phase in the ongoing redevelopment of redundant office buildings in the area, providing open public spaces and contemporary living just a short distance from the River Thames.

Comprising of 104 luxury apartments and penthouses, the site also includes a ‘Little Waitrose’ store, a coffee outlet, restaurant and office space. In addition, the development features an underground car park, where parking is allocated to a number of the apartments and to the commercial units.  Each apartment boasts private outdoor space and floor-to-ceiling glazing, further enhancing views.  The North facing apartments have stunning views out over the city.

Fire Design Solutions (FDS) was appointed following the initial smoke ventilation contractor’s departure from the project. This saw FDS required to work to a strict deadline of three months in order to maintain the existing completion date for the project.

Working with previously approved designs, FDS was required to take a unique approach, sourcing the equipment specified while also incorporating a corridor environmental system into the smoke extraction system.

By using the existing mechanical smoke ventilation system to provide day-to-day ventilation, FDS was able to provide an efficient and cost-effective solution to potential overheating in the development’s common corridors.

As smoke venting systems are a requirement in multi-storey buildings such as this, utilising the system for environmental ventilation purposes allowed St James to maximise the space available while reducing costs by removing the need to specify a dedicated ventilation system.

By providing this fire engineered solution, FDS was able to ensure that the development had higher standards of fire safety than those required by Approved Document B (ADB), while adhering to the deadlines put in place to ensure that the project was delivered to schedule.

Situated beside the Emirates Stadium, Queensland Terrace is a large-scale mixed use development, providing housing, restaurants, cafes, bars and offices for the area of Islington, London.

The final housing phase in regeneration works by Arsenal Football Club, the development includes more than 700 homes, with 252 being affordable. The development is also home to the new Arsenal Sports Centre, providing a space for the club’s educational and community programmes, as well as access for local residents.

Appointed to the project by main contractor Kier Construction, Fire Design Solutions (FDS) was enlisted to design, supply and install a number of fire safety systems, including mechanical smoke venting and fire alarm systems to provide means of escape and fire fighting access. By applying a value engineered approach to the design of cores 2, 3, 4 and 5 in the Southside block, FDS was able to reduce the number of smoke shafts per core from two to one, providing significant added value and benefit to the project.

Corridor environmental systems were also installed, performing the duty of day to day air venting of common corridors by utilising the smoke venting systems, saving both installation costs and space.

FDS’ final appointment was to design, supply and install a residential fire sprinkler system to satisfy British Standard 9251 requirements.

FDS also worked with Kier to overcome an installation issue, interfacing bin store extraction fans with the fire detection system to ensure that they shut down once ‘fire fighting mode’ was engaged.

Working to satisfy Building Control standards, FDS undertook extensive commissioning and system testing to ensure the high quality performance of all systems.

Award-winning fire safety system design and installation contractors Fire Design Solutions (FDS) has completed work on one of London’s most prestigious large scale residential projects.

Working with developer Galliard Construction, FDS provided the design and installation of a number of smoke venting systems, including the pioneering Firesmart intelligent control system, across the Greenwich development.

Unusually for a development of this size, the project was not delivered in phases – meaning that FDS had to deliver across all 12 blocks within the same tight timescale.

FDS was tasked with designing, supplying, installing and commissioning mechanical smoke venting systems within each block, along with corridor environmental systems that alleviate the common corridor overheating issue.

The BS 5839 compliant ‘FireSmart’ control panel system installed as part of the project provided a great deal of flexibility and simpler installation for the FDS team on site, as all fire systems were included in a single loop. Utilising the system also enabled installation teams to add or extend systems much more easily than is usually the case.

FireSmart will produce status reports and commissioning logs at New Capital Quay, making it an integral part of the building’s ongoing fire plan.

Further variations were added to the project in the form of a smoke clearance system within the underground car parking area of each block, which utilises a thrust ventilation system to clear smoke quickly from the enclosed area in the event of a fire. FDS was able to not only install this in line with the original project schedule, but also conduct a phased handover of the car park, requested halfway through the project.

Gerard Sheridan, Chairman at FDS, said: “The key to the successful management and completion of this project was co-ordination with the developer, with whom we’ve worked before, and our fellow contractors.”

The mixed used development boasts more than 1,000 individual dwellings along with shops, offices, leisure facilities, underground parking and a health centre.

Located adjacent to Tottenham Hale tube station, the Hale Village mixed-use development provides 1,193 student accommodation units alongside 1,000 private and affordable residential units, a 132 bedroom hotel and substantial commercial space.

Initially brought on board by United House to install mechanical smoke ventilation systems for one of the development’s affordable housing blocks, Fire Design Solutions (FDS) was asked to install systems for a further two blocks, plus an underground car park that runs beneath the site. A further appointment by Willmott Dixon saw FDS take on work at two of the development’s ‘Pavilion’ private residential blocks.

Working with multiple clients and their architects, FDS installed three different systems within the development, consisting of natural and mechanical smoke ventilation systems and corridor environmental systems.

FDS was also required to design, supply, install and commission the car park smoke clearance system utilising a Thrust Ventilation system, carbon monoxide detection system, fire alarm system and attenuation. Once on site, FDS carried out assessments and tests to determine the smoke flow rate likely to be created from a two car fire, in line with British Standards for car parks (BS7346 Part 7). Using the data gathered, FDS’ specialists engineered a smaller venting system for the car park than was originally included in the designs. This was justified by demonstrating that the required 10 air changes per hour could still be achieved in the area affected by smoke.

The assessment and subsequent system design led to large reductions in the fan size needed, which in turn reduced the size of associated cables and controls, necessitating a smaller plant room. As a result of this space saving the end client was able to create more saleable car parking space whilst minimising costs. The works also saw FDS retrofit an existing fire alarm system to the car parking area.

As the work on site took place over the course of three years, the car park was handed over in stages. This introduced a challenge for FDS, as the areas of the car park which were completed earliest were situated next to sections that were still undergoing work. This issue was overcome through intelligent programming of the detection systems, and by disabling it in certain areas to ensure that the installed system was not affected by ongoing work.

In addition, Fire Design Solutions was awarded with the service and maintenance contract for the site.

Part of a regeneration scheme to redevelop an existing housing estate in Edgware, Greater London, the Evolution project saw Barratt West London, the London Borough of Barnet and Family Mosaic Housing Association working together to deliver a 999 unit residential scheme.The development included a mix of private and social housing and the development team enlisted the expertise of FDS to design a turnkey package solution which included a fire strategy and the design and install of smoke venting systems.

Throughout the development there was a lack of natural ventilation so, using the company’s in depth understanding of fire engineering First Principles and its proven technologies, FDS addressed this issue by:

  • Installing two full smoke shaft extraction systems which provided mechanical smoke clearing for the taller blocks thanks to fans located on the roof
  • Designing an ambient airflow venting system for the taller blocks that utilised the mechanical smoke venting system to extract heat from the ceiling voids
  • Using CFD (Computational Fluid Dynamics) modelling to aid in the design of the smoke venting and ambient airflow venting systems and to demonstrate their effectiveness

In the basement car park, FDS worked with the design team to rationalise the basement venting requirements.

Thanks to the expertise and solutions-driven approach of FDS, the fire safety installation provided substantial value engineered savings, whilst offering high levels of safety.

Consisting of one of Europe’s largest Tesco stores, 6 blocks of residential properties and a multi-level car park, the Woolwich Central development forms part of the ongoing regeneration works in South-East London.Recognising the complex fire safety considerations that need to be made for large mixed-use projects, Willmott Dixon appointed award-winning smoke ventilation system contractors Fire Design Solutions (FDS) to provide its design and installation expertise.

Following a design and build appraisal, including CFD (Computational Fluid Dynamics) Modelling, FDS was able to justify the retail space’s large compartment size by specifying the use of a smoke extraction system.

The store’s loading bay was also fitted with an engineered mechanical smoke extraction system. By detecting carbon monoxide levels the system provides day-to-day extraction, meeting Approved Document F (ADF), as well as clearing smoke in the event of fire.

In the development’s residential areas, FDS’ specialist contracting team installed mechanical smoke ventilation and corridor environmental systems, removing excess heat from common areas throughout the development whilst still protecting the building’s staircases from smoke in the event of fire.

Within the car park FDS provided full mechanical and electrical installation of a smoke/heat detection and clearance system to provide environmental extraction and smoke ventilation. The system was interfaced with the development’s Building Management and fire alarm systems.

Due to a tight schedule and project variations, FDS was set a challenging five month deadline to carry out all works, a target which was achieved, allowing the store to open on time.

 

A major scheme for Barratt Homes East London, the St Andrews Hospital project will see the site of a redundant Victorian hospital redeveloped as six buildings of residential apartments, each with integral parking. The development also includes a day care centre, a dental surgery and retail units, all situated around a central courtyard.

The proposed size, location and partial commercial use of three of the buildings meant that they would be subject to the requirements of Section 20 of the London Building Act, which requires a more stringent level of fire safety to mitigate the risk of fire spread. In many cases, this would necessitate higher construction costs but, systems developed and installed by the expert team at FDS not only kept costs to a minimum but also enabled justification of extended travel distances, reducing the number of staircases by 20 to provide valuable additional floor space.

The experienced team at FDS was able to achieve this by:

  • Installing an enhanced mechanical smoke venting system in the car park which meant that the installation of a sprinkler system in the car park in Block D and 5 and commercial areas could be avoided, thereby saving more than £500,000.
  • Developing the smoke venting and integrated environmental corridor cooling system, which enabled justification of extended travel distances and removed the need to specify fire shutters.
  • Reducing the space required for smoke shafts thanks to the installation of smaller mechanical smoke shafts, maximising saleable floor space.

The creative team at FDS developed a bespoke solution for each of the buildings in the development to maximise safety whilst minimising costs. In Block B the expert team custom-designed the smoke shaft system and designed and installed the sprinkler system. The team used the FS1 Double-Knock Floor Sprinkler System, which utilises water supplied from the Boosted Cold Water Supply in the common riser on the floor. This approach omitted the requirement for a separate sprinkler tank and pump, and will also minimise the risk of water damage caused by vandalism. Thanks to the team’s computer modelling expertise, FDS was then able to justify this innovative approach to fire safety in Block B using CFD (Computational Fluid Dynamics) modelling.

CFD modelling was also used extensively in Block C to help inform and justify the design of a bespoke smoke venting system and in Block A, FDS designed and installed a fan-assisted smoke venting system. Thanks to the technical understanding and value engineering expertise of the FDS team, the fire safety installation at the St Andrews Hospital development saved significant costs by reducing the specification, reduced the amount of time required on site and yielded additional floor space.

Loampit Vale, constructed by Barratt Homes, is an extensive regeneration scheme that will transform the centre of Lewisham. The £150 million scheme, delivered in partnership with the London Borough of Lewisham, will deliver a state-of-the-art leisure centre along with 788 mixed tenure homes, commercial units and a new cultural quarter. Due to the company’s significant track record, FDS was appointed to provide a total end-to-end solution for a fan assisted smoke venting system and associated smoke detection system for the residential common areas, along with a car park ventilation system.

FDS utilised an innovative approach to system design and installation to provide:

  • Significant cost savings in the materials and systems used as a result of FDS’s end-to-end service
  • Improved environmental credentials – the Impulse system installed in the car park removes cars’ carbon monoxide emissions.
  • A venting shaft schematic that maximises the space available, assisting in meeting architectural aspirations and justified by utilising FDS’s technically advanced CFD (Computational Fluid Dynamics) modelling techniques

For Block A the expert team from FDS designed a smoke venting system to serve all twelve storeys with fans fitted at roof level on the top of the shaft and a sliding smoke vent fitted at the head of the stair.

Meanwhile for Blocks B to D, the team designed an identical system, to serve eight, fourteen and nine storeys respectively, each with the same roof level fan and sliding door at the head of the stair.

For all of the four blocks the FDS team also used the company’s knowledge of fire risk and behaviours to design a smoke detection system and corridor environmental system, integrated with the fan-assisted smoke venting system and the building’s BMS (Building Management System). The mechanical smoke extraction system incorporated a smoke detection system in the common corridors which would activate the system automatically to operate on the affected level only.

The corridor environmental system was based on mechanical extraction of heat from the ceiling void into the smoke shafts using motorised dampers above the ceiling void that will be motored open whilst the environmental system is operational. This system is linked to both a timer and a thermostat ensuring that it is operational between the hours of 6am and 8pm during the summer and/or if the temperature reaches the pre-set threshold. Should smoke be detected in any level the environmental system would revert to the designed smoke ventilation system.

The FDS-developed fan assisted system is proven to outperform standard code-based systems: in the event of a fire it will rapidly remove smoke to aid the means of escape and protect the staircase for fire fighting services. The Impulse system installed in the underground car park removes air pollution and smoke via extract fans, providing more energy efficiency, space and cost savings than a traditional ducted system.
