Tamiami Trail Project-Florida: “Mr. Vyas and the whole Interra team were instrumental in contributing to the high quality work provided to the USACE. Interra’s management went above and beyond in meeting our needs.” Larry Corn, Area Quality Manager, Kiewit Infrastructure …
Trusted Results. INTERRA’s technology-driven materials testing laboratories are some of the most efficient in the country and are designed to deliver consistent results and documentation. Additionally, as a company with no outside ownership interests and therefore, with completely independent laboratories, clients can confidently rely on their test results throughout the duration of their project.
Rapid Results. Our state of the art facilities employ automatic equipment and data acquisition systems to minimize operator and data entry errors. Our proprietary, in-house data management system and Quality Control procedures help ensure accurate results and expedited turn-arounds for faster, more confident decisions. So…no matter if it’s five samples or five thousand, you can be confident that INTERRA’s reliable test results will be delivered when needed.
Accredited. INTERRA’s materials testing laboratories have been accredited by a number of regulatory agencies including: US Army Corps of Engineers, ASTM/AASHTO, and various state departments of transportation.
