Terracon's Manchester office is located in the heart of New Hampshire's "Queen City," in a historic shoe factory building situated along the Merrimack River. The Manchester office was originally founded in 1986 by Gary Jaworski, Ph.D., P.E., as Jaworski Geotech, Inc. (JGI). The multiple disciplines offered by Dr. Jaworski and his early staff are still our specialty today. Many original client relationships established by Dr. Jaworski continue to this day, as long-term clients and client referrals comprise the majority of our business. JGI merged with Terracon in 2007, becoming part of the national, award-winning, employee-owned consulting firm, and providing a reliable presence in the New England region. The primary services offered to clients in both the public and private sectors include geotechnical, environmental, and construction materials engineering and testing. In addition, the Manchester office provides hazardous building materials services (asbestos, lead paint, and mold related services), Special Inspections, and we have a certified soils and concrete laboratory. The professional staff consists of geotechnical engineers, geologists, hydrologists, environmental scientists, and project managers. Projects span several business sectors including transportation, energy, federal, telecommunications, education, healthcare, and commercial and retail development.
