Uwe M. Janssen, Founder & Principal of Rauch Safety & Engineering, serves as a consulting and testifying expert in matters involving fall protection, façade access (including Building Maintenance Units, BMUs), suspended access, permanent access, rigging, and rescue systems.

Mr. Janssen brings more than four decades of field and assessment experience with these systems on landmark and high-consequence assets in the United States and internationally. He has been retained by counsel on approximately 30 matters, on behalf of both plaintiffs and defendants. He is the author of the Integrated Design Guide for Work-at-Height & Access Systems (Edition 3, 2026).

Most experts enter a matter after counsel has decided it needs one. Mr. Janssen can also be brought in earlier, before designation, to test whether the technical position warrants moving forward. Counsel can then retain him as the testifying expert under a separate engagement, or retain someone else. Services include early case technical evaluation, consulting support through discovery and settlement, and expert reports, deposition, and trial testimony.

Rauch Safety & Engineering does not manufacture, sell, install, maintain, or service equipment. Plaintiff or defense. U.S. and international matters.
