How do you find construction engineering books in the Dewey decimal system?

The Dewey Decimal System classifies books according to ten broad subject areas, and consists of three digits (000-999), which may be followed by a decimal point and a range of numbers. This number is then followed with the first three letters of the author's last name.

To find construction engineering, you would use the following path:

600 - Technology

620 - Engineering

624 - Civil Engineering

Depending on the specific topic you are looking for, you may then continue to narrow down the classificiation number. For example:

624.1 - Structural engineering and underground construction

624.17 - Structural analysis and design

624.177 - Structural design and specific structural elements

624.1773 - Trusses and frames
