The engineer of record attributed the fatal design flaw to a breakdown in communication. Subject coverage includes all aspects of civil engineering, ranging from aerospace, architectural, coastal and ocean, computing in civil engineering, construction, energy, engineering mechanics, environmental, and geotechnical to hydraulic, infrastructure, materials, management, professional issues, structural, transportation, urban planning, and water resources. In terms of ultimate load capacity of the connection, the minimum value should have been 1. The shearing forces caused the failure due to lack of firm foundation supporting the floors. Other than the third floor now being left without a connecting walkway, the lobby generally retains its original design.

Had this change in the hanger rod design not been made, the maximum capacity of the design connection would have been far short of Kansas City building code requirements which require a minimum value of 33. Was it a man-made disaster? Rescue teams would later liken the scene to a war zone. The short rods plus the lack of threads in the rods depicted structural weakness.
