posted 04.02.2015

OLATHE, Kan. — Terracon, a leading provider of environmental, geotechnical, materials, and facilities services is pleased to announce the ownership of two soils testing and materials laboratories in the Upper Midwest. The offices, located in Vernon Hills, Ill., and Green Bay, Wis., were most recently operated by AECOM, and previously owned by STS Consultants, Ltd.

Terracon will retain three employees currently working in the offices.

The acquisition allows the company to further expand its services and geographic presence in the region, which includes offices in Naperville and Chicago, Ill., and Milwaukee, Wis.

“These laboratories have completed testing on thousands of projects, many under the supervision of the former STS Consultants, Ltd.,” says Matt Catlin, P.E., division manager of the Naperville/Chicago offices. “Many of these projects were highly complex and included a number of iconic structures. Gaining that experience will help us to provide faster and more cost-effective consulting to our clients.”

The Vernon Hills facility is one of the few commercial laboratories which offers rock mechanics testing capabilities. The laboratory is accredited by the National Voluntary Laboratory Accreditation program (NVLAP), AASHTO Materials Reference Laboratory (AMRL), and is validated with the U.S. Army Corps of Engineers (USACE).

“These two offices have an excellent regional history and reputation,” said David Gaboury, P.E., Terracon’s president and chief executive officer. “We are excited to offer our clients solid, experienced services which align seamlessly with our expertise.”

Purchase of the Vernon Hills and Green Bay locations officially closed on March 11.

Terracon is an employee-owned engineering consulting firm with more than 3,500 employees providing environmental, facilities, geotechnical, and materials services from more than 150 offices in 42 states.
