SSPC Checklist of Items Commonly Found in

Specifications for Coating Steel and Concrete

NOTE: Use applicable portions of this document for each project, and add requirements not listed here as appropriate to produce a competent design.

General contract considerations

• Coordinate with owner’s “front-end” documents (General Conditions, Additional General Conditions, Special Conditions, etc.)

• Define scope of project fully (Get detailed field conditions if maintenance work) Contract specifications (using CSI three-part Section format)
