Vertical transition and interface at passenger boarding bridge portal gate 407, bounded by the Level 03.1 concourse slab at elevation 137'-4 3/4" and the bottom of curtain wall at elevation 133'-4 3/4". The floor assembly consists of a built-up concrete slab on metal deck supported by cold-formed metal framing and structural steel haunch supports. Metal panel cladding wraps the structural steel haunch support below the deck level, accommodating conduit routing as allowed by the PBB installer. A fixed passenger boarding bridge connects adjacent to the portal wall, maintaining a minimum clearance above flashing details at the interface. The exterior facade incorporates CW-3 fixed glazing and alignment dimensions referencing the face of the portal.
