Non-testifying consulting support for counsel on matters involving fall protection and access systems, including BMU, suspended, and permanent access systems (U.S. and International)

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.

Work focuses on system failures, installation alignment, and responsibility across design, manufacturing, and construction, particularly where breakdowns occur between design intent and real-world conditions.

Scope includes analysis of:

• 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
