    • Review the content of the SSPC Guide for Planning Coatings Inspection
    • Common formats of inspection plans
    • Common inspection check points that are transferred from the specification to the inspection plan
    • Common inspection instruments, standards, guides and methods used to perform inspection that are listed on an inspection plan
    • Listing the acceptance criteria from the specification onto the inspection plan
learning outcomes
Learning Outcomes
  • Completion of this webinar will enable the participant to:
    • Describe the purpose and importance of an inspection plan
    • Explain the benefits of an inspection plan
    • Recognize the SSPC Guide for Planning Coatings Inspection
    • Describe the various formats of inspection plans
    • Extract inspection check points from a specification
    • Identify the instruments, guides and methods used to inspect
    • Extract the acceptance criteria from a specification for each of the inspection check points
    • Prepare an inspection plan
purpose of an inspection plan
Purpose of an Inspection Plan
  • Provides a systematic inspection and testing plan that covers all phases of work in sequence
  • Provides a written document that lists what to inspect, how to inspect and the acceptance criteria
  • Provides a tool enabling an inspector to navigate through and extract inspection check points from the specification
  • May be a required contract submittal
benefits of a coatings inspection plan
Benefits of a Coatings Inspection Plan
  • Coating specifications can be complex documents
  • Specifications typically contain the quality requirements for a coatings project
  • Good inspection doesn’t happen by accident; it requires planning
  • Inspection plans make specification enforcement more streamlined and complete
  • Provide a key communication tool between QA and QC personnel

  • Developing an Inspection Plan
  • Process Control Procedures (PCPs)
  • Items Required for Inspection Plan Preparation
  • Listing of Common Inspection Instruments & Guides
  • Inspection Hold Points/Check Points
  • Sample Coating Inspection Plans (steel & concrete)
required items for developing an inspection plan
Required Items for Developing an Inspection Plan
  • Documents
    • Project specification
    • Referenced standards (SSPC, NACE, ASTM, etc.)
    • Product data sheets
    • MSDS
  • Inspection Equipment and Guides
    • The project specification and referenced standards will identify the appropriate test methods and equipment required
inspection plan format
Inspection Plan Format
  • Variable, depending on contract documents and inspector preference
  • Simple (three columns)
    • Inspection Check Point
    • Method of Inspection
    • Acceptance Criteria
  • Complex
    • Simple format, plus three additional columns
      • Testing Frequency
      • Standard Test Method Reference
      • Specification Reference (Part/Item No.)

developing an inspection plan
Developing an Inspection Plan
  • Example based on maintenance painting of a bridge structure
  • First, populate from the specification:

Column 1: Inspection check point column

Column 3: Frequency of test column

Column 5: Specification reference column

Column 6: Acceptance criteria column

  • Second, populate inspection method (Column 2) and standard test method (Column 4)

  • Complete the inspection plan by populating the remaining two columns
    • Inspection instrument/technique
    • Standard test method reference
