A bridge coatings specification can be a complex and sometimes confusing document to navigate through. Yet it is regarded as the rulebook for quality control and quality assurance personnel responsible for inspecting the quality of work. An inspection plan is a tool that can make the process of understanding the inspection checkpoints invoked by a bridge coating specification more streamlined and can be a key communication tool for contractor and inspection personnel.
A bridge coatings specification can be a complex and sometimes confusing document to navigate through. Yet it is regarded as the rulebook for quality control and quality assurance personnel responsible for inspecting the quality of work. An inspection plan is a tool that can make the process of understanding the inspection checkpoints invoked by a bridge coating specification more streamlined and can be a key communication tool for contractor and inspection personnel. This presentation reviews the purpose and benefits of developing an inspection plan and the content of SSPC’s Guide for Planning Coatings Inspection, illustrates two formats for inspection plans and demonstrates how to populate an inspection plan based on the requirements of a bridge coating specification.
This paper describes a bridge coating operation and maintenance manual that was developed for the City of Vancouver which operates and maintains an inventory of 33 bridges with coated steel elements.

Overcoating an existing bridge coating system can be an economical solution to maintain bridges. Overcoating eliminates the costs for removal of old, often hazardous coating systems that were possibly applied years ago. However, prior to the overcoating process, it is necessary to establish that the existing coating is well adhered to the substrate. Coatings with inadequate adhesion must be removed. Unfortunately, though some standard test methods are available, the determination of a well-adhered coating is not an exact science.
One of the, if not the most, vexing problems for bridge maintenance personnel is the deterioration of bridge components below leaking joints. The joints may be open or closed, construction or expansion, but all seemingly leak shortly after construction or resealing. The bridge components affected by the leaking joints may be steel or concrete, but the end result is the same, deterioration.
