the nations worst building collapse, a crowded
walkway in the Kansas City Hyatt Regency Hotel failed
in 1981, killing 114 people and injuring more than 200.
NIST experts found that the design of critical connections
in two walkways had been changed from the original plans
and did not meet local building codes. Their findings
led the American Society of Civil Engineers to adopt
a document that for the first time assigned responsibility
for various aspects of the construction process.
