2018 Greenbook: Standard Specifications for Public Works Construction
For over 50 years, the “Greenbook” has set the standard for public works specifications for hundreds of cities, counties, and agencies in Southern California. Over the years, interest in the “Greenbook” has spread throughout the United States, Canada and many other countries overseas.

First published in 1967, the “Greenbook” promotes uniformity, and eliminates conflicts and confusion, among the plans and specifications used by local public agencies. Use of the “Greenbook” lowers construction costs by encouraging participation in competitive bidding by more private contractors. It is the work of an active volunteer committee of professional agency members who are thoroughly versed in the changing technology and advanced thinking of the construction industry.
