This essential resource is the "graphical companion" to the "Greenbook" (Standard Specifications for Public Works Construction). It features hundreds of standardized drawings and dimensional details covering every aspect of public works construction; from street improvement and sewers and sanitation, to street lighting, traffic signals, retaining walls, landscaping and irrigation systems - now all in standard English units. It also features cross-sections that clearly illustrate the latest approved techniques, and exhaustive notes covering every detail - with clearly spelled out answers to any question you might have. Most importantly, it contains all the latest changes that have been researched and approved by the 25-member "Greenbook" committee, which includes representatives from the American Public Works Association , the Associated General Contractors of California, the Engineering Contractors Association, and the Southern California Contractors Association.
