Hart Companies

Elite Craftsmanship. Family Values. Life Science Precision.

For over 40 years, Hart Companies has been building spaces that power the most critical work in the world - the manufacturing, development, and delivery of life-saving drugs.

We’re a family-owned, Rhode Island–based firm that has quietly become a trusted name in life sciences facility design, engineering, construction, and passivation. Our reputation is rooted in craftsmanship, consistency, and the kind of execution that delivers results with measurable cost, quality, and timeline outcomes.

From master planning to commissioning support, we specialize in facilities/utilities/process design for pharmaceutical, biotech, chemical, and industrial clients.
