Our Roots, Focus, & Expertise


Daniel O’Connell’s Sons is recognized as a unique group of professionals who simply love to build. For generations, people who respect the building process and relish construction challenges have driven work to DOC. Our firm has deep roots in virtually all types of construction. We’ve built everything from classrooms to dams, theaters to bridges, and laboratories to high rise towers.


Our business is focused on helping private clients and public agencies successfully address their most important and difficult challenges. We’re among the best at planning and implementing projects that are technically complex and require particular management and engineering expertise.

Because of this focused approach, we’ve earned a reputation as one of New England’s premier builders, capable of managing the most sophisticated and challenging projects – and we’ve proven it time and again.

We’ve demolished and rebuilt a bridge on an active Boston commuter rail line during a 72-hour holiday weekend. Our work on Boston’s Central Artery Project included subsurface construction 120 feet deep, through an operating mass transit station. The award-winning Rowes Wharf complex and its below-grade parking was built largely on piles in Boston Harbor.
