Allegheny Contracting was founded in 1997 by Brent Buehler as a one man, part-time residential excavating and remodeling service operating as Allegheny Contracting and Construction.
The company quickly grew to the point where additional help was needed, and soon had a part-time team of three employees working to satisfy the demand.
In early 2001, work had grown to the point that it justified a more formal and full-time business structure. At this time, the name was changed to Allegheny Contracting LLC, and eight full-time employees were put on staff.
The team drew on its experience and expertise to successfully compete in the public works market installing water and sewer infrastructure, along with commercial building construction, and small bridge construction services.
