Routine design When we think of bridges, it is the dramatic and monumental long spans that come to mind first, especially the lithe suspension bridges such as the Golden Gate and the pure geometric arches such as Sydney Harbour. But the majority of bridges are not such spectacular structures. Most of them are ordinary overpasses, with spans of 30 or 40 feet, carrying roadways or rails across other thoroughfares or over small streams. You see such bridges by the dozen on any drive down the Interstate. They may be lacking in glamour, but they are more representative of a bridge builder's art. The engineering and construction of girder bridges are pretty routine these days, but the bridges are not quite standard items you order from a catalogue. The girders, whether of steel or concrete, are custom-build for each bridge, then trucked to the site and hoisted into place with a crane. The designer still has scope for variation and creativity, and it shows out on the highways: some overpasses are prettier than others.

The management strategy that saved Apollo 11 An Article by Matthew Ström matthewstrom.com In 1969, the people in charge of Apollo 11 trusted a 23-year-old engineer in a back room of mission control to make one of the most consequential decisions of this decade-defining mission. And they did so in seconds, without deliberating or debating. Next time you’re faced with a decision, ask yourself: how can this decision be made on the lowest level? Have you given your team the authority to decide? If you haven’t, why not? If they’re not able to make good decisions, you’ve missed an opportunity to be a leader. Empower, enable, and entrust them. Take it from NASA: the ability to delegate quickly and decisively was the key to landing men on the moon.
