Greenbook Changes for Plastic Pipe
The “Greenbook” is used throughout southern California for public works construction, and is often referred to by agencies and consulting engineers in other localities as a guide specification. It has been changed significantly in 2009 relative to contractor requirements for installation and deflection testing of plastic pipe. These changes should be carefully reviewed by Engineers and Contractors prior to specifying or using plastic pipe, as the new requirements could have significant cost impacts, as well as affecting considerations whether this flexible pipe is appropriate for the intended application.
