About us
TREVIICOS: history, know-how and innovation

TREVIICOS was founded in 1997 when TREVI acquired ICOS to combine the world wide experience of TREVI with ICOS' knowledge of the North American market.

Active in North America since 1964, ICOS has made construction of hundreds of infrastructure projects and renowned buildings possible, including the World Trade Center in New York City. Soon after its inception, TREVIICOS was awarded a major contract for the complex foundation system of the new Southeast Expressway, better known as the Big Dig.

As work on the Big Dig projects ended, private development in the Boston area flourished, offering opportunities for TREVIICOS to be involved in the construction of new hotels, condominiums, office buildings as well as medical and educational facilities.
