Top construction companies in Massachusetts

Massachusetts anchors New England’s economy, and its construction sector reflects that weight. The state is home to some of the country’s largest and oldest builders — employee-owned general contractors that have worked here for a century, heavy-civil firms rebuilding the region’s highways and bridges, and specialty developers putting up the labs, hospitals, and clean-energy projects that define the local market.

This post ranks the top construction companies headquartered in Massachusetts by their position on Engineering News-Record’s 2026 Top 400 Contractors list, which ranks firms by their 2025 construction revenue. Every revenue figure and rank below comes from ENR’s published list; sources are linked throughout.

Suffolk also plans its workforce with Bridgit — connecting estimates in Ediphi directly to staffing plans so operations leaders can see roles, availability, and experience across dozens of concurrent projects in one place. Their team tells that story in full in this case study.

Nexamp

Headquarters: Boston, Massachusetts 2025 revenue (ENR 2026 Top 400): $698.0 million — national rank #194

Nexamp is a Boston-based clean-energy company and one of the largest community-solar developers and asset owners in the United States. Founded in 2007 by two US Army veterans, it handles the full lifecycle of its projects — development, design, construction, operations, and customer management — which is why its build work registers on ENR’s contractor list even though it is a renewable-energy developer rather than a general building contractor.

Nexamp’s work includes:

• community and distributed solar development
• solar and battery-storage construction
• agrivoltaic and “solar grazing” projects

Middlesex operates as a family of companies — including Middlesex Paving, Middlesex Asphalt, and Mass Ready Mix — that lets it self-perform much of the paving and material supply on its heavy-civil work. That vertical integration is a core reason the firm can take on the large transportation contracts that define its portfolio.

Notable mentions

Suffolk Construction (#23) runs one of the largest project portfolios in the country, with dozens of major jobs going at once out of its Boston office alone. It plans its workforce with Bridgit — estimates built in Ediphi flow straight into Bridgit as staffing plans, so operations leaders see the roles a project needs, when people start and roll off, and who has the right experience across the whole portfolio. “You can see the open roles, see the available people, and match them together very quickly,” says project manager Steven Jennings. “In Bridgit, it becomes almost plug-and-play.” Read the full Suffolk case study.
