The Harrington Group

I had never hired a fire protection engineer, but I’m certainly glad I did. For every dollar that I paid Harrington Group, I believe your advice saved me almost fifty dollars in unnecessary or less optimal build-out costs. That kind of ROI makes me real happy! — Richard Sheroff, Signet Key Ventures, Inc.

Computer Fire Modeling

Fire protection engineers use complex mathematical tools for analysis involving fire and life safety in buildings. These tools, often referred to as computer fire models, are particularly valuable when the analysis involves comparing the relative merits of two possible solutions where one solution is prescribed by the building code and the other is an alternative method developed by the fire protection engineer.

In addition, computer fire models have proven to be powerful tools for investigators performing post-fire reconstruction and analysis.

Capabilities of modern computer fire models include:

  • Predicting fire growth and behavior
  • Evaluating occupant egress
  • Analyzing smoke control systems
  • Predicting detector actuation time
  • Providing plausible post-fire timeline of events
