ReEngineering the Engineer: Security 101: COVID, a New Level of Growing Pain
Life was seemingly simple when I started engineering. We printed out a large floor plan from the architect and drew the floor framing on tracing paper. Then we designed one beam after another, writing the reactions on the plan, then the girders, then on to the columns and carrying the reactions down to the foundation. Difficult? Not really. Tedious?

From exposed soils to concrete, trash and solvents, pollutants present at construction sites, if uncontrolled, can easily be conveyed offsite and into waterways, degrading water quality and damaging delicate ecosystems. To limit such degradation, the discharge of stormwater from construction sites is regulated at several levels: federally by the U.S. Environmenta...
