Plan Sheet Library

The Plan Sheet Library provides drawings of site-specific details and experimental designs that are precluded from adoption as Standard Plans. These drawings each have a narrative explaining the intended use and some of the possible impacts associated with its usage.

These drawings were developed and are supported by the Headquarters Design Office; however, they are provided “as is”. The user assumes full responsibility for the plan’s adequacy to address a specific construction situation and for any alterations to the drawing by the user.

When a drawing from this Plan Sheet Library is used in a contract document, a Professional Engineer must review the plan and accept full responsibility for its contents in the manner prescribed by the Washington State Department of Licensing.
