Commercial construction is one of the clearest indicators of a region's economic momentum, and Greater Hartford has plenty of activity to show. Major healthcare systems are expanding medical campuses, universities are investing in research and student facilities, aerospace and advanced manufacturing companies are upgrading plants, and developers are reimagining downtown districts near the riverfront and around Dunkin' Park. Distribution centers continue to rise along the I-91 corridor north of the city.

The commercial construction firms that succeed in this environment bring deep technical expertise, robust safety programs, and strong financial capacity.
