Pharmaceutical and cleanroom construction is not ordinary commercial work. A single airborne particle, a poorly coordinated trade, or a material that sheds or outgasses can compromise a controlled environment and jeopardize an FDA or third-party inspection. These projects demand contractors who understand ISO 14644 classifications, cGMP requirements, and the precise coordination of HVAC, electrical, controls, and fire protection that contamination control requires.
That is the work DHH Construction does every day. We build and renovate the controlled environments where pharmaceutical and healthcare products are made — with an on-site presence at a major pharmaceutical manufacturing facility that trusts our team inside its walls.
