Ahneman Kirby, LLC is the result of a merger between two outstanding firms and traditions: Ahneman Associates started in 1988 by Edward and Thomas G. Ahneman in Greenwich, CT and J.A. Kirby Company started in 1871 by Joseph Andrew Kirby in Port Chester, New York. Joseph Kirby’s legacy includes the Boston Post Road (Rte.1) bridge that spans the Byram River at the “Gateway to New England” – the State of Connecticut Boundary.
J.A. Kirby’s surveys, sewer designs, road designs, and storm water designs shaped the Village of Port Chester at the end of the 19th century. Many of his maps and designs are in use today and Ahneman Kirby, LLC is the proud steward of Kirby’s records, and continues the J. A. Kirby tradition of time tested civil engineering work.
Ahneman Associates founders Ed, Jr. and Tom G. Ahneman are second and third generation civil engineers. Edward Ahneman, Sr. was a civil engineer on the team that built the Kensico Dam in North White Plains, New York, the New York City water supply reservoirs, and was chief engineer overseeing the construction of New York City water supply aqueduct tunnels 5 and 5A which are still in use today.
Principal, Thomas G. Ahneman, P.E. has extensive engineering experience in structural designs. He obtained his B.S. in Civil Engineering from UCONN in 1981 focusing on structural and geotechnical disciplines. He worked for a NYC consultant designing high rise structures while performing coursework toward a Master’s Degree at City College CUNY. He joined his father in Greenwich, CT in 1985 to provide structural expertise to the firm.
