The Minnesota Department of Transportation (MnDOT) with KTA-Tator, Inc. (KTA) conducted a one-day seminar on Bridge Maintenance Painting Strategy & Project Design in May 2013. One outcome of that seminar was the realization that MnDOT needed a more uniform method to rate the condition of coatings statewide during the biennial bridge safety inspections and a process to select and prioritize maintenance painting strategies. MnDOT assembled a Technical Advisory Panel to address these needs and launched a multi-objective study from October 2013 through June 2014.

This paper identifies the unique steps taken to safely remove lead-based paint from a major highway/commuter railroad bridge connecting Philadelphia, Pennsylvania with Camden, New Jersey, followed by the application of a new long lasting protective coating system. The paper addresses project phasing by the owner and coordination with the commuter train to keep costs down and to minimize inconvenience to the public.

This paper examines the authors successful experiences on some simple and very complex projects where both the coatings and environmental requirements were limited to a few pages. Being made up almost entirely of SSPC/NACE and PDCA standards that described “performance criteria” as opposed to being a prescriptive or proprietary type of specification defining what was to be used, when it was to be used and how it was to be done.
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.
