Flushed with success

Flushed with success

A core responsibility for a commissioning team is making sure that systems perform as they’re designed to do. Sometimes that takes creativity—like the time of the big flush.

While building Seattle’s Qwest Field football stadium, one test required flushing all the toilets at once to simulate the worst thing that might happen during a half-time break. As every worker in the massive structure stood ready the fire alarm sounded, flush handles went down, everyone waited in suspense—and several stories below, water rushed into a street-level loading dock. The culprit: a city sewer drain had been partially blocked by gravel.
