Engineering in Plain Sight: An Illustrated Field Guide to the Constructed Environment is a 2022 non-fiction book by civil engineer Grady Hillhouse. Published by No Starch Press, the work identifies and explains the physical infrastructure of the modern world, including the electrical grid, water treatment systems, and telecommunications networks.
The book has been recognized for its accessibility and technical accuracy, leading to its inclusion in major public library systems across the United States, including the Anne Arundel County Public Library, the Austin Public Library, and the Black Gold Library Consortium.
The book's development was an extension of Hillhouse's work as the creator of Practical Engineering, a YouTube channel focused on civil engineering education. Hillhouse, a licensed professional engineer (PE), began the project to address what he described as a lack of "infrastructure literacy" among the general public.
He modeled the book's structure after traditional biological field guides, such as The Sibley Guide to Birds. Rather than focusing on historical narrative, Hillhouse intended the work to be used as a "spotter's guide" for readers to identify and understand the components of the built environment they encounter in daily life.
The book is organized into eight functional chapters, using detailed illustrations to catalog various types of civil hardware:
A central feature of the book is its reliance on technical illustrations over photographs. Hillhouse argues that diagrams allow for the removal of "visual noise," such as shadows or surrounding vegetation, which can obscure critical engineering details in a photograph. The illustrations often use cutaway drawings to show the internal workings of sealed components and exploded axonometric views to demonstrate how multiple parts interact within a larger system.
The book emphasizes the theme of "informed simplicity," which maintains that complex systems can often be best understood through their constituent parts. Hillhouse advocates for a greater public understanding of infrastructure, suggesting that a citizenry that understands its water and power systems is better equipped to make decisions regarding public works and sustainability.
The book was well-received by both engineering professionals and general readers. Library Journal recommended the work for all libraries, noting its high-quality production and its ability to answer common questions about the built environment. Design World highlighted the book's value in explaining "everyday engineering," specifically praising the use of clear illustrations over potentially confusing photographs.
In addition to its popular appeal, the book has been integrated into educational frameworks and academic collections. It was featured in the Purdue University INSPIRE Engineering Gift Guide, where it was described as an "invaluable tool" for engineering design learning. The book has also been included in academic library acquisitions and new materials lists for institutions such as Western Illinois University and Del Mar College.
In 2024, Bill Gates included the book on his "Holiday Books" list, stating that "it's easy to take these things for granted until they break." Other reviews noted its utility as a reference for curious travelers and those interested in the "hidden" mechanics of the modern world.
