My First Mistake as an Engineer

Main Ideas and Lessons

The presenter introduces his forthcoming book, Disasters By Design, about major engineering failures, how they happened, and how disasters have shaped building codes, regulations, and engineering practices.

He recounts his first construction-site mistake. As a new engineer monitoring groundwater at a dam project, he lowered a bailer—a sampling device—into a monitoring well. He had accidentally used the shorter of two ropes on a spool, and the bailer fell into the well.

After worrying about the cost and consequences, he asked workers on site for help. They improvised a rescue using fishing gear from a nearby store, and he eventually retrieved the equipment.

The incident challenged his idealized view of engineers as infallible experts. He came to understand that engineering is done by capable, well-intentioned people who are still human and make mistakes.

The story illustrates how individual errors can lead to shared precautions. People learn from mishaps, pass on what happened, and gradually incorporate lessons into procedures, regulations, and codes.

The broader point is that modern infrastructure can be remarkably reliable, but that reliability is built through accumulated experience—including failures. Many existing structures and safeguards are responses to earlier mistakes or disasters.

Book and Release Information

• The book is scheduled for release in March and includes a chapter on the 2020 collapse of the Arecibo Radio Telescope.
• A US pre-order offer includes an exclusive Arecibo poster while supplies last. It applies to pre-orders from US retailers, including the audiobook.
• Signed US copies are available through Nowhere Books in San Antonio.
• The audiobook will be released at the same time as the book and read by the author.
• A UK edition will also be available, with differences mainly in spelling and units. The presenter says readers in many locations should be able to find an edition through a bookseller.

Speakers and Sources Featured
