Rauch Safety & Engineering provides non-testifying technical consulting to counsel in matters involving fall protection systems, façade access systems (including Building Maintenance Units – BMUs), and permanent access infrastructure.

Engagements are typically initiated prior to expert designation to evaluate the technical validity of a claim, defense, or opposing position. This allows counsel to determine whether a matter is structurally sound before proceeding into formal expert pathways.

• System design and engineering intent 
• Installation and commissioning conditions
• Lifecycle use and maintenance environments
• Alignment with applicable standards (OSHA, ANSI, IWCA)

RSE is engaged to:

• Evaluate case feasibility and technical merit
• Identify system failures, misalignment, and responsibility gaps
• Analyze construction defects and performance issues
• Review and assess opposing expert reports 
• Determine design vs. installation discrepancies 

RSE operates independently of contractors, manufacturers, and installers, providing unbiased technical evaluation grounded in real-world system behavior across the full system lifecycle.

All engagements are strictly non-testifying and available across U.S. and international matters.

Key Services

• Early Case Technical Evaluation (Fall Protection & Access Systems)
• Construction Defect & System Performance Analysis (Fall Protection & Access Systems)
• Failure Analysis – Fall Protection & Access Systems
• BMU / Façade Access System Review
