Many construction-related resources can be found in books of the same color.

Originally compiled by a 400-person task force in Southern California, The Standard Specifications for Public Works Construction — aka The Greenbook — is now produced by Public Works Standards Inc., a mutual benefit corporation with board members from the Associated General Contractors of California, the Engineering Contractors Association, the Southern California Contractors Association, and BNi Publications Inc.

A 25-member committee, comprised of representatives from these organizations and other members of public agencies and utilities, updates the reference manual every three years to create a “living” document that reflects the latest technological and contracting developments.

The Greenbook's influence has spread far beyond its California roots; its specifications have been adopted by more than 200 cities and counties and even made their way into the hands of managers overseas.

With the wealth of reference materials available, especially “green” resources related to sustainability, we offer the following to avert potential confusion:

AED Green Book

Published since 1949, it provides average rental rates for construction equipment from hundreds of rental dealers nationwide.

EDC Green Book

The Sustainable Product & Resource Guide helps architects and designers find products and services indexed by CSI code.
