After the prepainting meeting, obtain and review the contractor’s painting quality work plan for structural steel painting or paint removal.

Refer to Section 155, “Paint,” of Structure Construction’s Bridge Construction Records and Procedures manual for guidelines on inspecting surface preparation, paint application, thickness of paint film, and protective measures. Included in this section is a bridge painting checklist that will aid with verification of contract compliance.

Take the following steps:

  • Ensure that surfaces have been prepared as the specifications require.
  • Allow application of paint only to thoroughly dry surfaces and only during periods of favorable weather.

4-5904 Quality Control

Department acceptance for structural steel painting consists of verification inspection that validates the contractor’s quality control sampling and testing program. This verification inspection consists of witnessing the contractor’s quality control to ensure that the contractor measures coating thickness, coating adhesion, and soluble salt levels at the frequency specified and at locations determined by the resident engineer.
