Municipal

INTERRA has provided  engineering, inspection, and testing services for municipal clients that demand quality work products and responsive service on a consistent basis.  Municipal clients maintain long-term relationships with INTERRA because they know they can count on us to get the job done…no matter what the job is.

As one example of many, a municipal client initially retained INTERRA to determine subsurface soil stratification for a new salt dome.  This project was then quickly followed by a subsurface investigation for a proposed roadway reconstruction project and another to perform asphalt coring and test analyses.  Ultimately, INTERRA was retained for another four geotechnical investigations in rapid succession.

Additional examples of INTERRA’s work with municipalities can be found below.
