Clough Harbour


CHA Consulting, Inc. is an international engineering consulting and construction management firm headquartered in Albany, New York. The firm was founded in 1952 by John Clarkeson, P.E., in Boston, Massachusetts, and focused on civil design work. The firm was subsequently purchased by Ronald Clough and renamed Clough & Associates. Ronald Clough then partnered with Bill Harbour and the firm was renamed Clough, Harbour & Associates, LLP.
Some of the firm’s first notable projects were its work on Boston’s "Inner Belt" highway and the Interstate Highways throughout the Northeast.
CHA has grown substantially since then and now has a large presence in several different engineering fields, including power supply and distribution, communications infrastructure, structural, electrical, mechanical, environmental, geotechnical, civil, aviation, rail, and traffic/transportation engineering, as well as landscape architecture, land use planning, surveying, sports and recreation, wetland delineation, construction engineering and technology services.
In 2020, Engineering News-Record, a publication which ranks design firms based on information about their revenue, ranked CHA as the 61st largest engineering design firm in the United States.
CHA Consulting and its subsidiary companies were sold in 2018 to First Reserve, a private equity firm that focuses on the acquisition of internationally-based energy companies.
