We’ve come a long way from Ben Franklin’s kite and key experiment in a lightning storm. Today, electricity literally powers the world economy. Evolving electrical system design keeps everything– from communication and supercomputing to financial trading and logistics– buzzing. Whatever your electrical design needs, our electrical engineers offer technical expertise relative to reliability, resiliency, and flexibility for:

  • Normal / Emergency / Standby / Uninterruptible Power
  • Cogeneration / Distributed Generation Systems
  • Electrical Monitoring and Control Systems
  • Energy Conservation Retrofits
  • Mission Critical Systems
  • Reliability Analysis Reports
  • Site Power Distribution Systems


Arguably our most precious natural resource, water is the life blood of any building. And clean and efficient water systems are at the heart of these structures. Proper sanitation systems prevent disease and contribute to healthy environments. Our plumbing design and consulting services include incorporating domestic water supply, sanitation, and storm water systems into your facility’s design. Plumbing engineers at ESD offer design solutions and technical expertise for:

  • Domestic Hot- and Cold-Water Distribution
  • Food Service/Pumping
  • Sanitary and Storm Drainage
  • Water Treatment
  • Acid Dilution Systems

Fire Protection and Life Safety Engineering

Fire Protection/Life Safety

In Maslow’s hierarchy of needs, safety is cited as one of our most primal and basic human requirements for a happy and healthy life. Today’s advances in technology help building owners and managers meet that need with state-of-the-art systems and equipment. But these safety nets are only as good as their implementation and use. Properly designed and functioning fire protection, life safety, and fire alarm systems provide facility occupants, operators, and owners with a higher level of confidence that they are safe within their facilities.

Our technical specialists offer you peace of mind by providing expertise and design solutions for:

  • Fire Pump Booster
  • Wet/Dry/Pre-Action Sprinklers
  • Clean Agent Suppression
  • Fire Alarm and Monitoring Systems
  • ADA and Local Code Authority Systems / Analysis
  • Hazard Analysis and Insurance Rating Coordination
  • Hydraulic Calculations and Flow Analysis


This specialized branch of engineering is focused on the science of sound and vibration. Working with our other in-house engineering teams, Acoustical focuses on the design, analysis, and control of sound to deliver a superior environmental experience for our clients. In other words, designing and retrofitting spaces to meet the needs of our clients for quiet, private, and comfortable spaces facilitating clear communication and excellent sonic signature is our primary objective.
