Corporate Construction is now Meridian.
Meridian Controlled Environments is the new name — and unified global brand — of Corporate Construction, Inc. Same people, same standards, and the same relationships our clients have relied on since 1999, now operating as one company built for a global stage. The name changes; the accountability, the record, and the team behind it do not.

Why clients consolidate with us.
Most controlled environments are assembled from a fragmented chain of architects, contractors, mechanical vendors and service providers — and risk hides in every hand-off. Meridian closes those gaps. We plan, build, monitor, maintain and update the entire environment, and we bring specialized capability in-house — from cleanroom construction to high-purity process piping — so the details that decide yield, sterility and compliance never fall between the cracks. We are not design-build. We are build-and-design: discipline first.

Built for a global stage.
Headquartered in Danbury, Connecticut, Meridian delivers across the United States and beyond — serving semiconductor and high-tech, healthcare and life sciences, pharmaceutical and biotechnology, and government and defense clients, often the same clients, again and again.

The standard never moves.
As the industries we serve push into ever-smaller tolerances and ever-stricter regulation, the margin for error keeps shrinking. Meeting an exact standard, every time, is the whole point of our name — and the reason we’re built for what you build next.
