Project Experience
RIBA Stage 02-04 Fire Strategy
Delta Fire Engineering engineers provided full fire strategy design from RIBA Stage 02 through to Stage 04 on a mixed-use commercial /residential scheme in Kent. The scheme was situated close to the site boundary on two sides and required detailed external fire spread analysis to rationalise the amount of fire rated glazing required.
Detailed means of escape design was carried out at ground floor and basement level to ensure that escape routes from the different tenancies were separate thereby reducing the requirement for ventilated lobbies, whilst ensuring means of escape were adequately sized for the respective tenancies.
Residential CFD Modelling
Delta Fire Engineering engineers utilised Computational Fluid Dynamics (CFD) modelling to specify the required extract rate for a mechanical smoke control system in a high-rise residential building in London.
The modelling compared the proposed mechanical system (with 0.6sq.m cross-sectional area) against a 'code-compliant' 1.5sq.m natural system to demonstrate increased performance over the prescriptive guidance approach.
The performance-based design solution allowed the architect to realise their design aspirations whilst ensuring that conditions within the means of escape were maintained within acceptable limits.
Fire Risk Assessment
Delta Fire Engineering engineers carried out a Fire Risk Assessment at a stadium in the North West of England.
Our team attended site to review the existing condition in a stadium that had been closed for an extended period, highlighting fire safety hazards that required remediation.
The Fire Risk Assessment was tailored to the Clubs need to make the stadium occupiable prior to the commencement of the new football season.
Retrospective Fire Strategy
Delta Fire Engineering engineers adopted a performance-based design approach when compiling a retrospective fire strategy for an industrial facility in West Yorkshire.
The site had a large floor area and remote exits which resulted in significantly extended travel distances, however by taking account of the large ceiling height and applying a zone model methodology we were able to demonstrate that the means of escape remained tenable throughout the means of escape phase.
This allowed the client to retain the existing fire exits and remove the requirement to carry out alteration works to the building fabric.
London Plan Fire Statement
Delta Fire Engineering engineers provided support during the planning stage by providing a Fire Statement in support of Policy D12 of the London Plan.
The scheme involved the demolition of existing garages and construction of 6 dwellinghouses in southeast London. The London Plan Statement included detailed setting out plans for Fire Brigade access to the dwellings, including a marked-up site plan showing hydrant location and hose lay routes.
The statement provided justification for provision of a watermist system in lieu of residential sprinkler system throughout units.
