The firm operated as a sole proprietorship (Spencer F. Thew, PE-LS) from 1972 through 1999 and was affiliated with Atlantic Testing Laboratories, Limited (ATL) from 1972 through 2007, which was also founded by Spence in 1967.
In 2007, Spence put away his transit, steel tape, and slide rule to pursue other interests in his retirement years; however, we continue to tap his 50 plus years of surveying, engineering, and construction experience, as the advice he offers and the perspective he provides are always valuable.
Spence has Bachelors of Science and Masters of Science degrees from Clarkson University in Civil Engineering and Geotechnical Engineering, respectively. He obtained his surveying experience working under the supervision of Spencer J. Johnston, PLS (No. 024084) in the Adirondack Mountains and Champlain Valley of New York, and under the direction of Harry Lord in St. Lawrence County.
Spence became a licensed Professional Engineer and Land Surveyor in 1967 and 1972, respectively. He seized upon the need for high quality topographic, bathymetric, utility, and boundary surveying and mapping, and construction surveying and as-built mapping for the architectural, engineering, and construction industries throughout Central and Northern New York.
Jim has a Bachelors of Science degree in Surveying Engineering from the University of Maine (Orono) and became a Licensed Land Surveyor in 1996. He obtained his practical surveying experience working under the supervision of Spence (Dad), and remembers being “Dad’s rodman” at the tender age of six (there was no enforcement of child labor laws back in the early 1970’s). From 1997 through 2005, Jim managed ATL’s Drilling and Geotechnical Engineering Division responsible for the execution of land and water based geotechnical and environmental investigations. In 2006, he decided that he would focus on growing the survey company and subsequently resigned his position with ATL. It has proven to be a very satisfying decision.
