First published in 1967, the “Greenbook” promotes uniformity, and eliminate 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.
