Session 1 - Corrosion Control Using Protective Coatings (1.5 PDH)
Corrosion is a process where metals (e.g., steel) give up energy and return to their natural state. There are significant costs and consequences associated with corrosion; the National Association of Corrosion Engineers estimates that the cost of corrosion approaches $300 billion annually. While corrosion cannot be completely halted, it can be slowed. The most widely used method to prevent/slow the onset of corrosion today, particularly on carbon steel, is the application of high performance coating systems. Session One includes the definition of corrosion, explains the
corrosion process and the elements of a corrosion cell, describes various types of corrosion present on bridge structures, and highlights design configurations that are conducive to corrosion. The role of high-performance coatings in corrosion prevention is explained, including the various protective properties of coatings: barrier, inhibitive and galvanic. Session one is worth 1.5 PDH credits.
Session 2 - Bridge Coating Maintenance Strategies (2.5 PDH)
While properly installed coating systems can protect steel bridges for 25 years or more, they require interim maintenance to control corrosion and minimize surface preparation requirements. Cost-effective maintenance requires scheduling the repair of coatings before deterioration progresses to the point that the only option is total removal and replacement of the coating system. However, prior to selecting a maintenance strategy, the condition of the existing coating system must be carefully assessed. This session will emphasize the importance of steel bridge coating system maintenance and will explain the impact on
installation costs and life-cycle costs. The importance of assessing the condition of the existing coating system will also be described, as well as how the results of the coating condition assessment are used to determine whether maintenance painting is warranted, and which strategies are likely to provide adequate preservation of the structure.  There are five maintenance painting strategies that may be selected for any given painted steel bridge. These include: do nothing, spot repair, spot repair and overcoat, removal and replacement in zones, and removal and replacement of the existing system for the entire structure. The advantages and limitations of each will be explored. Session two is worth 2.5 PDH credits.
Session 3 - Coating System Selection for Steel Bridges (2.5 PDH)
There are a variety of coatings and coating systems that can be used to protect steel bridges; selection is based on the prevailing service environment, the maintenance strategy, available funding and other factors. The advantages, limitations and curing mechanisms of common steel bridge coating systems will be described in Session Three, along with the function of the various coating layers, the importance of coating thickness and when selection of two coat systems may be justified over traditional three-coat systems. The impact of Volatile Organic Compound (VOC) regulations on coating system selection will also be explained. The use of duplex coatings systems (hot-dip galvanizing with liquid or powder coating finishes) and thermal spray coatings (and the associated industry guides/standards) will be discussed, as well as when and where the use of weathering steel may be justified.  
 
Most steel bridges contain connections that are slip-critical. When the EOR elects to coat faying surfaces, the coatings (i.e., primers) are required to demonstrate resistance to slip once the bolts are tensioned. Session Three will include an explanation of how coatings are tested and classified according to the requirements of Appendix A of the RCSC Specification for Structural Joints Using High-Strength Bolts.  
 
Because not all generic coatings systems are created equally, many transportation agencies will create an Approved Products List (APL) or Qualified Products List (QPL) based on laboratory testing of candidate coating systems and/or successful track records. Session Three will conclude with an overview of the National Transportation Product Evaluation Program (NTPEP) for Structural Steel Coatings, as well as how the Northeast Protective Coatings Committee (NEPCOAT), a consortium of ten northeastern states, including Massachusetts uses NTPEP-generated data to generate an APL. Session three is worth 2.5 PDH credits.
Day 2 - Tuesday, March 20, 2018
William D. Corbett, Chief Operating Officer, KTA-Tator, Inc.
Michael Hewins, Coatings Engineer, Massachusetts Department of Transportation
 
Session 4 - Surface Preparation Methods & Standards (2.5 PDH)
Preparation of steel surfaces for coating application is typically regarded as the most important step, as it effectively lays the foundation for the coating system. Session Four begins a discussion of pre-surface preparation concerns that may need to be addressed in coating specifications (e.g., edges, weld spatter, laminations, section loss, grease/oil, chemical contaminants, etc.). Various methods of surface preparation will be described, including advantages and limitations of each, and which are appropriate for shop work versus field preparation. Subsequently, factors associated with selection of surface preparation method(s) for inclusion in coating specifications (e.g., maintenance strategy, coating system requirements, access and worker/environmental concerns) will be discussed. Session Four will conclude with a discussion of the industry standards for surface preparation published by organizations such as ASTM International, SSPC: The Society for Protective Coatings, and NACE International that can be used in the preparation of project specifications. Session four is worth 2.5 PDH credits.
Session 5 - Quality Assurance & Quality Control (2.5 PDH)
Verification of quality is a shared responsibility of the facility owner and contractor. The roles and responsibilities of quality assurance (QA) and quality control (QC) personnel and the associated reporting relationships will be explored in Session Five. The inspection requirements that may be invoked by project specifications related to pre-surface preparation, surface preparation and coating application for both existing and new steel bridges will be described. Session Five will conclude with a discussion of the inspection instruments, visual guides and test kits that are used to verify quality at each step of the surface preparation and coating application process. Session five is worth 2.5 PDH credits.
Session 6, Part 1 - Coating Specifications (1.5 PDH)
The first part will focus on the purpose and content of coating specifications, including common formats. The instructor will compare coating specification content for new steel bridge structures, (including the advantages and limitations of total shop painting), and coating specifications for maintenance painting of existing structures (including sequencing and impact of the maintenance strategy on specification content). Part one will conclude with a discussion of specification preparation, including common submittal requirements. Session six, part one is worth 1.5 PDH credits.
Session 6, Part 2 - MassDOT's Approach to Protection of Steel Structures (1 PDH)
The second part of Session Six will be led by Michael Hewins, Bridge Coatings Engineer, who will describe Mass Highway’s approach to protecting steel bridge structures from corrosion using protective coatings. Mike will describe the maintenance strategies employed by the Agency; the coating systems used; surface preparation methods specified; contractor certification requirements; and management of quality assurance inspection. Mike will also share some of the challenges his Agency encounters related to corrosion control of steel bridges in Massachusetts. Session six, part two is worth 1 PDH credit.
