Terracon’s Longmont office was established in 1978 as Empire Laboratories. The office was opened with just one person, Edward Paas, P.E., who is still the office manager. In 1992, Terracon acquired Empire Laboratories. The small, but dedicated staff have provided quality engineering and construction materials engineering and testing services along the Front Range to projects including the 29th Street Mall Redevelopment, I-25 Widening between WCR 16 to SH 119, Longmont United Hospital additions, multiple park and municipal projects for the City of Longmont, and St. Vrain Valley School District’s new school construction and improvements.
