For the ninth year, Core States Group has earned a spot on the 2026 MEP Giants list by Consulting-Specifying Engineer, which recognizes the nation’s leading mechanical, electrical, plumbing, and fire protection engineering firms. This year, we ranked #67, climbing a spot from our #68 ranking in 2025.

The annual ranking is based on MEP design revenue and provides a snapshot of the evolving building systems engineering market. This year’s report reflects continued momentum across the industry, with the 100 ranked firms reporting a 27.7% increase in combined MEP design revenue over the previous year.

Behind this recognition is a team that understands how building systems affect every aspect of a client’s operation. As energy demands, technology, and code requirements continue to evolve, our MEP/FP teams collaborate closely across disciplines to solve complex challenges with solutions that support each client’s goals.

Whether supporting a national rollout, a new prototype, or a complex facility upgrade, our team brings technical depth and a solutions-focused mindset to help clients move from early planning through project delivery with confidence.

We are proud of this recognition and grateful to our clients, partners, and team members who continue to make it possible.
