Design Checking

As the Country’s leading independent fire engineering consultancies with over twenty years experience in the development of fire engineering solutions and the application of fire safety standards. LWF provide an independent fire engineering checking and validation service designed specifically for Building Control Departments.

New developments and refurbishment schemes are increasingly relying on fire safety engineering solutions. More particularly, relaxation against prescriptive fire safety standards is sought for reasons such as occupancy capacity or travel distance. LWF can therefore provide services tailored to meet these changing needs by reviewing fire safety submissions to:

  • Identify fire safety design criteria
  • Validate design methodology
  • Identify any deviations from the codes
  • Assess all results against the design criteria

Independent qualified evaluation of proposals and installed systems to ensure compliance with design intentions for either fire engineered or prescriptive applications, including

  • Fire Strategies
  • Evacuation Procedures
  • Fire Suppression Systems Designs
  • Fire Alarm and Detection System Designs
  • Means of Escape
  • Structural Fire Separation

Independent assessment of contractors commissioning and compliance certification.

Definition of requirements and options for remedial measures.

Computer-aided analysis of complex design solutions.

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...
