We are pleased to announce that GTA Associates, Inc. (GTA) has relocated our Raleigh office, formerly on Chapel Hill Road, to Building 2 within the Merritt Midway Business Park, in Knightdale, NC. This new, larger space accommodates our growing company and includes an expanded soil, concrete, and asphalt testing lab allowing us to better serve the needs of our clients.

GTA has two locations in North Carolina. We opened our original Raleigh office in 2015. Our Charlotte office was opened in 2006. The new Raleigh area office in Knightdale is managed by Shawn Sullivan and provides geotechnical engineering, environmental consulting, natural resource services, and construction observation testing and special inspection services for residential, commercial, utility, and infrastructure projects. This office is supported by the technical expertise and resources of our other 20 offices and 500 employees.

Please note our new address:

530 Hinton Pond Road, Suite 104, Knightdale, NC 27545
