Mechanical and Electrical Engineering

A reliable mechanical and electrical system is the backbone of every great facility.

At SEH, our integrated mechanical, electrical, lighting, and controls engineering teams offer comprehensive solutions for building and infrastructure projects across the country.

Our engineers and designers collaborate seamlessly to deliver efficient and reliable systems. From facility HVAC, plumbing, and site utilities to industrial systems design, bridge lighting, outdoor roadway, and plant controls, we cover a wide range of disciplines.  

We work alongside our clients to identify, specify, and implement reliable and efficient systems ‐ systems your staff will understand, and users will appreciate, even if they don't know it's there.   

Mechanical Engineering 

Stainless food grade

Our mechanical engineering team works across all SEH services to provide engineering services geared toward facility HVAC/plumbing and site utilities. We work across multiple areas such as municipal, water/wastewater, retail, federal, colleges/universities, and industrial/manufacturing. Our experts are not only skilled in facility design, but also possess expertise in the less common projects that require an understanding of corrosion protections and hazardous area classifications commonly found in industrial settings.
