Our Featured Projects

What We Do

For over 20 years, CES has been providing exceptional MEP engineering services for design, energy assessments, commissioning, and construction administration projects.

The CES staff of over 75 employees specialize in mechanical, electrical, plumbing and fire protection services for analysis, design, and construction administration throughout the United States. As a medium sized firm, CES is divided into manageable teams consisting of 5 to 8 engineers. Each team is a well-rounded, experienced group of engineers representing each discipline, overseen by a project manager and a firm principal. This cohesive team approach allows CES to bring depth, personalized service and a collaborative atmosphere to each project. Working as a team allows there to be a comfortable, open line of communication between all design team members which is fundamental to ensuring a project is completed on schedule and within budget. As part of our commitment to sustainable design and energy saving practices, CES is a certified LEED™ consultant with Certified Energy Managers, Certified Geothermal Designers, Certified PV Designers and Certified Commissioning Professionals all on staff. Combined with our in-house Construction Administration and Commissioning team, CES is able to provide our clients with complete quality control on new and existing building systems.
