We've been around 126 years for a reason.

Our long established ties with the institutions, businesses, and municipalities in surrounding communities further our commitment to quality construction. Maintaining low overhead and a manageable number of projects per year, DAS can guarantee 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. Accordingly, our overall management philosophy is one of personal attention, quality, and long-term dedication to an Owner. This generally fosters relationships that last well beyond the lifetime of a project.
