Construction materials engineering and testing services included fill placement monitoring, soil compaction testing, shallow foundation evaluations, f-numbers verification, reinforcing steel verification, reinforced concrete testing, structural masonry verification/testing, structural steel testing and concrete and asphalt paving testing.
Terracon's Austin office was originally founded as HBC Engineering in February 1994, and then acquired by Terracon in December 1998. The office has more than 50 engineers, geologists, scientists, and technicians. All of the department managers in the Austin office have been with Terracon between 12 and 16 years. Our services include geotechnical engineering, construction materials engineering and testing, and environmental consulting.
Terracon provided Phase I environmental site assessments, geotechnical engineering and Quality Assurance testing and inspection services for the Formula 1 racetrack and associated buildings. The project included a 1,000+ acre site with 3.4 miles of winding racetrack, two tunnels, a main grandstand, pit building, team buildings, media building, medical building, parking areas, and an electrical substation.
Established in 1975, Midwest Testing Laboratory (Midwest Testing) has provided geotechnical engineering and materials engineering and testing services on a wide variety of projects in the upper Midwest, including North Dakota, South Dakota, Minnesota, and Montana. Midwest Testing was acquired by Terracon in 2010 to enhance our services in North Dakota and surrounding states.

Terracon has also consulted on site redevelopment for building…
The Blennerhassett Bridge is the final project in a decades-long effort to complete the four-lane Appalachian Corridor D from I-79 at Clarksburg into Ohio. HCN, a Terracon company, completed three geotechnical phases for the originally planned suspension bridge alternate. During the first phase, a preliminary geotechnical investigation was performed initially by drilling 21 test borings in November of 1999. A second geotechnical study was performed by drilling 34 borings in December of 2000. The second and third phases provided recommendations for the foundation alternatives at the towers, cable bents, and anchorage of the suspension bridge alternate.
The West Virginia Division of Highways opted for a tied-arch design after evaluating four concepts for the bridge; comparing factors such as cost construction and environmental issues. The final geotechnical phase performed by HCN established recommendations for the Short Span Tied Arch Alternate. During the construction phase of the…
