About DAS

Established in 1897, DAS has served all of New England, primarily the Western and Central Massachusetts area, for over 125 years!  With annual sales of ~$50 million, DAS typically manages 15 projects a year. Well regarded in the construction industry, DAS maintains deeply rooted ties to the surrounding communities.

 

Personal attention to project management and value to the customer have allowed DAS to remain a competitive presence in both the public and private construction markets.

 

Our long established ties with the institutions, businesses, and municipalities in the surrounding communities further our commitment to quality construction. Maintaining low overhead and a manageable number of projects per year, DAS can guarantee the personal attention and commitment required to bring a project to a successful completion. We've continually completed projects on time, within budget, and with strong satisfaction from our clients.

 

The staff at DAS shares in our commitment to excellence. Many of our employees have been with us for over 20 years. Some represent a second generation of their family's involvement with our firm. Accordingly, our overall management philosophy is one of personal attention, quality, and long-term dedication to an Owner. This generally fosters relationships with an Owner that last well beyond the lifetime of a project.
