Hollow structural section soffit framing ties into supporting steel beams, girts, and column grid lines A and B. The assembly utilizes L4x4x1/4 angles connected with 3/8-inch thick connection plates and two 3/4-inch diameter A325-SC-OVS bolts spaced at 3 inches on center. Fillet welds of 1/4-inch size and complete joint penetration welds with ultrasonic testing (CJP UT) secure the structural steel components. Architectural elements including wall panels, soffit panels, and a hangar door interface with the steel framing according to specified architectural drawings.
