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.
