When reviewing mechanical plans, which item is NOT typically considered?

• A. Traffic Patterns
• B. Electrical Layout
• C. Ventilation Systems
• D. Plumbing Piping

Answer: (A)

Reviewing mechanical plans focuses on the systems that move air and fluids—ventilation and air distribution, exhaust, piping for water and waste, fuels, and the equipment and controls that serve them. Electrical layout can appear in coordination with mechanical work, since equipment needs power and control wiring, but the main concern is the mechanical installation and performance. Traffic patterns, by contrast, deal with how people move through spaces and how egress is organized—topics handled by architectural and life-safety planning, not the mechanical system design. Because of that, traffic patterns are not typically part of mechanical plan review.
