We’re happy to announce the
promotion of
Sarah Kaddatz to
Lab Manager
Kurt Bell to Associate.

We recently received Small Business Enterprise (SBE) certification by both BART and LA Metro. Our 22-person firm has specialized in rail transit noise and vibration control since 1966. Our services have contributed to hundreds of successful projects over the decades, and now we’re pleased that we can also help primes meet SBE goals.

Wilson Ihrig has set up our entire staff to work from their homes until it is safe to return to the office. Much of our work falls under the designated “essential” category, so please do not hesitate to reach out to us during this time about how we can help your with your project.

We are fully operational and are committed to continuity of service.

Currently, all client meetings are done virtually, and essential travel and site visits are done in accordance with CDC guidelines.

We look forward to the day when our daily lives return to some semblance of normalcy.  We hope that day is not too far off. Until then, we wish you and yours all the best in terms of health and otherwise.
