Which elevation shows the exterior roll-up door and personnel entrance doors into Mechanical/Electrical Room No. 0.1?

The correct answer is the West elevation, as it provides a view that typically includes features such as roll-up doors and personnel entrances for a Mechanical/Electrical Room. In architectural drawings and blueprints, different elevations give distinct perspectives on the building's exterior, and the West elevation is where these features are commonly located.

Exterior roll-up doors are typically used for service access and would be more prominent on that elevation, allowing for easy access to mechanical and electrical equipment. Personnel doors, which provide access for staff, are also strategically placed for convenience and safety, often near significant operational areas like the Mechanical/Electrical Room.

In contrast, other elevations may not showcase these features, as roll-up doors and entrances are designed considering functional accessibility and spatial layout. Therefore, identifying the West elevation as the location of the exterior roll-up and personnel entry into Mechanical/Electrical Room No. 0.1 is informed by common architectural practices in building design.
