Fire Engineering Solutions

Modern building design is tending ever towards larger, more open plan concepts. This design approach requires that the normally applied prescriptive fire safety standards utilised in more traditional building designs, become restrictive in their application. Statutory design guidelines give the option for developers to move away from the prescriptive fire safety constraints and use an approach that enables engineered solutions to be applied specifically to new and existing buildings.

This approach enables the designer to take full advantage of design features and to offset one fire precaution measure with others that may positively contribute towards an aesthetically and engineered optimum solution. Existing buildings, subject to redevelopment or refurbishment, can also benefit from a fire engineered approach, the benefits here in addition to potentially reduced costs and restrictive measures, can include less intrusion particularly if the building is of a Listed or ‘fine’ nature.

Fire engineering techniques require the designer to prepare a specific design for a building taking into account the features, proposed use and occupancy of the facility. Prescriptive applied standards are general in their nature and are required to be applicable to all buildings put to a similar use. For maximisation of building potential and optimisation or even feasibility of design, the fire engineer becomes an essential advisor to the facility manager or member of the project design team.

LWF are able to undertake on your behalf:

  • Identification of rationalised potential life and property losses.
  • Analysis of fire and smoke behaviour in large or complex spaces.
  • Quantified analysis of fire risk.
  • Solutions based on objective or cost benefit analysis.
  • Fire safety measures that fully utilise and take maximum advantage of existing building features.
  • Solutions that optimise capital outlay by prioritisation.
  • Computer aided modelling for detailed scenario prediction.
  • Analysis of occupancy and populations distribution to optimise emergency evacuation procedures.
  • Determination of integrated schemes using state of the art detection and suppression.
  • Tailor-made services to address special or high risks, including special-needs occupants, security, special hazards and salvage requirements.

FIRE SAFETY BLOGS

  • Fire Safety for Healthcare Premises - Vertical Escape - Part 23

    In LWF’s blog series for healthcare professionals, we look to give information on best practice in fire safety for hospitals and other healthcare premises. In part 22 of this series, we looked at the issue of vertical escape in relation to stairways and ascertained that in effect, all stairways in a hospital must be considered escape stairways as they would be used for escape in case of fire. In part 23, we will continue looking...

  • Facilities Management & Fire Safety - Inspection, Testing and Maintenance - Part 1

    In LWF’s blog series for Facilities Managers or those with an interest in or responsibility for fire safety, we aim to give an overview of best practice and methods of applying or maintaining fire prevention provision. In part 1, the importance of inspection, testing and maintenance of fire protection measures is discussed.Once fire protection measures are installed in a building, it would be comforting to think that they were simply waiting in case they...

  • Fire Engineering Design and Risk Assessment - Foam Proportioning - Part 4

    In LWF’s fire engineering blog series for Architects and others in the building design business, we have been looking at fire suppression systems and in particular, foam systems. In part 3, it was ascertained that foam proportioning is the means by which foam concentrate is mixed with water at the necessary ratio. An overview of inductors (also known as line proportioners) was given. In...

  • Fire Safety for Healthcare Premises - Vertical Escape - Part 22

    In LWF’s blog series for healthcare professionals, the aim is to give information on best practice of fire safety in hospitals and other healthcare premises. In part 21 of this series, LWF looked at the necessary considerations of hospital streets and escape route widths. In part 22, we will look at vertical escape using stairways.While it is possible for organisations to denote certain staircases as escape stairs (and therefore, certain staircases are not classed...

  • Fire Engineering Design and Risk Assessment - Foam Systems - Part 3

    In LWF’s Fire Engineering blog series for Architects and others in the building design business, we have been looking at fire suppression systems and, in particular, foam concentrate systems. In part 2, we began an overview of the different types of foam concentrate and part 3 will continue from that point before discussing foam proportioning.Synthetic, or high expansion foam is produced from detergents and, as a result, can produce great quantities of ‘bubbles’ making...
