Seventy-Eight Fire Consultants provides high quality engineering advice in the fields of fire engineering and fluid dynamics. Working with a variety of clients on an assortment of projects ranging from small shops to towering residential blocks, seventy-eight fire consultants can ensure whatever your project demand we can provide a safe solution in order to meet the functional requirements from The Building Regulations.

Our expertise lies in complex performance based fire strategies and Computational Fluid Dynamic (CFD) simulations. From extending travel distances within common corridor of residential buildings to determining the impact of smoke within atria, we can provide solutions for the common complex issues usually found in construction.

Please see below for a selection of projects our engineers have been involved with:

Peach Place (Wokingham): Fire Strategy - Peach Place is a mixed used residential and commercial development comprising of new construction and existing refurbishment. Work involved the development of a global fire strategy covering the entire development.

Design challenges: mixed use escape routes between residential units, commercial units and existing back of house areas.    Fire Consultants: Trenton Fire

Warrington Youth Zone (WYZ): Fire Strategy - WYZ is a state-of-the-art multi-purpose leisure facility designed for children and young adults. The facility is home to an external MUGA pitch as well as indoor court facilities. Work involved the development of a fire strategy involving thermal radiation analysis (TRA) of the external façades of the building.

Design challenges: Proximity of the development to the site boundary (B4 - external fire spread).    Fire Consultants: Trenton Fire

Shell Store Incubation Centre (Herefordshire): CFD Simulation - Redevelopment of a first world war shell storage facility into a new incubation centre. Work involved CFD simulation to determine the ASET/RSET required to provide tenable conditions for occupants during means of escape due to the large open spaces within the development.

Design challenges: Proximity of people egressing from a smoke layer contained within ceiling voids (B1 - means of escape).    CFD Fire Consultants: 78 Ltd

Manchester Youth Zone East (MYZE): Fire Strategy and CFD Simulation - MYZE is a state-of-the-art multipurpose facility containing a climbing wall, various courts, a sports hall, fully equipped gym and a music room with recording studio. Work involved modelling the impact of smoke curtain deployment on the ASET/RSET calculations to provide a safe means of escape for all people within the building.

Design challenges: Proximity of people egressing from a walkway near a void (B1 - means of escape).    Fire Consultants: Trenton Fire



Computational Fluid Dynamics Modelling: In order to assist both smoke control manufacturers and building designers to create effective smoke control systems, Computational Fluid Dynamics (CFD) is often employed to simulate air and smoke flow as well as heat transfer within buildings.

Modelling enables variety of commonly encountered situations in the building industry, a selection of these include:

  • Extended travel distances in residential corridors
  • Smoke control / clearance systems for car parks
  • Smoke control systems for atria
  • Commercial building ventilation

CFD simulation for fire engineering is provided using Fire Dynamics Simulator (FDS) developed by NIST, it is the industry standard for simulating buoyancy driven, low-speed flows as well as combustion.

Fire Engineering: At Seventy-Eight Fire Consultants we appreciate that no two buildings are ever 'simple' or the same, so why should the fire engineering aspects?

We therefore offer fully fire engineered solutions based on scientific research and performance based frameworks (BS 7974) to ensure you receive the most technically accurate solutions to your problems.

Fire Strategies: From simple buildings designed to Approved Document B (ADB), through more complicated commercial and residential buildings designed to BS 9999 and BS 9991, respectively, we can offer fire strategies to suit your need.

In addition to residential and commercial buildings we can also provide advice on schools (BB 100) and healthcare (HTM 05 series).

Reviews: Seventy-Eight Fire Consultants also offer reviews services relating to both fire strategies and CFD reviews. We work as independent reviewers for various Local Authority Building Control (LABC) as well as Approved Inspectors.

Seventy-Eight Fire Consultants typically review fire strategies written according to published guidance (ADB Volume 1, ADB Volume 2, BS 9991, BS 9999, CIBSE Guide E) as well as fire engineered solution based on the BS 7974 framework. Computational Fluid Dynamics (CFD) reviews are typically based on BS 7974 or the Smoke Control Association (SCA) Guide.

Fire Risk Assessments: Seventy-Eight Fire Consultants are able to offer Fire Risk Assements (FRA) as required under the Regulatory Reform (Fire Safety) Order 2005. In addition, we are also able to offer pre or post occupation FRA on complex or fire engineered developments.
