Our Story

Communication, Experience, and Flexibility

LEAD TO SUCCESSFUL PROJECTS

An open line of communication is critical to understanding your expectations and budget. We pride ourselves on collaboration to help you make timely decisions and move your project forward on time and within budget.

LRA has the breadth of experience you expect from your engineer with the added benefit of decades of combined experience in commercial and residential construction. This ensures that our designs are compliant and buildable.

When your engineer is flexible, your project goes smoothly. We easily accommodate changes in your project schedule, budget, and design criteria, while remaining sensitive to the desired end product. It is this flexibility that keeps our clients turning to Lewis Ross for their next project.

Better Design through Experience and Technology

MECHANICAL ENGINEERING

Our designs leverage the latest energy modeling and BIM technology ensuring compliant, efficient systems. Thorough knowledge of current equipment offerings makes for designs that provide the best value to our clients.

ELECTRICAL ENGINEERING

With decades of electrical contracting experience in the ranks, our designs are more cost-effective and buildable. Our communication with utility service planners moves projects forward faster and smoother. 

PLUMBING ENGINEERING

With our breadth of experience, our capabilities go beyond domestic water, waste, and gas. We handle hydronic, fuel gas, state-of-the-art boilers, lab gas, purified water, steam piping, process piping, and more.

GREEN BUILDING & TITLE 24

We excel at navigating the intricacies of the latest energy codes. Envelope and lighting calculations are all done in-house, providing well coordinated MEP designs that operate efficiently.
