Fire Protection Engineering

James Shannon, PE, LEED AP

Plumbing/Fire Protection Department Head


Often in conjunction with AEI’s plumbing practice, our fire protection engineers design systems to meet necessary life safety requirements. Our first objective when starting a job is to determine the occupancy classification of the facility in order to identify the assets needing protection. Then we match the fire load of the building to the appropriate suppression method in order to protect the building, simultaneously adhering to strict state building codes. We often work alongside our design team partners to coordinate with the HVAC and mechanical, electrical, civil, structural, and plumbing trades.

Our fire protection engineers identify all applicable codes and standards pertinent to each project and conform to those standards when designing fire protection systems. As part of our process, we identify system interfaces and the customer requirements applicable to the project.

Some of the systems we design include:

  • Design water-based fire protection systems
  • Pre-action systems
  • Dry-systems
  • Standpipe systems
  • Clean-agent fire suppression systems
  • Automatic wet-sprinkler systems
  • Fire pumps


Hydrant Flow Testing

We also perform hydrant flow testing and calculate the static and residual pressure and flow at the hydrant to determine the size of the pipe needed for a particular sprinkler system. By doing this in the design stage we are able to collect necessary data in a streamlined process that eliminates the cost, schedule, and need for a third party to perform the same task. Our hydrant flow testing services accelerate project deliverables and provide a single-source option to our clients.
