Plumbing Design

James Shannon, PE, LEED AP

Plumbing/Fire Protection Department Head


Hand in hand with our fire protection services, AEI’s plumbing designers provide clients with code-compliant plumbing solutions that integrate with all engineered systems for a reliable built solution. We work with our clients to determine required and appropriate systems for each building space, assist with choosing fixtures and optimal locations, and calculate all components for size and compatibility. We take current or expected occupancy into consideration when determining which systems are to be utilized in a building, work with our clients and end users to identify the types of systems needed and determine the permitting and code requirements necessary to pass state inspection. We perform calculations in order to size pipes, grease traps, water heaters, compressors, ejector pumps, and gas, oil, and sand interceptors, among others.

Some of the plumbing systems we design and specify include:

  • Sanitary and storm drainage and vent systems
  • Natural gas systems
  • Medical gas systems
  • Laboratory gas systems
  • Hot and cold water distribution systems
  • Acid neutralization systems
  • Commercial kitchen systems
  • Grease waste systems

All plumbing systems designed by AEI adhere to strict and relevant state plumbing codes, including Massachusetts State Plumbing Code 248 CMR.
