“Preparing an Inspection Plan for Bridge Maintenance Painting” (PDF114Kb) 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.

”Time is Money: Improving Shop and Field Painting Throughout by Reducing Finish Coat Handling Time” (PDF 558Kb) Handling and transportation of finish coated steel from the fabrication shop to the project site is impacted by the length of time that the finish coat must dry. Known as shop-field throughput, a reduction in the dry time required prior to handling (without compromising performance), as well as a minimization of handling damage can greatly reduce project costs. The authors believe that it may be possible to save at least one or possibly two full days of throughput time by using a two coat system (organic zinc or inorganic zinc silicate primer with a fast dry finish coat) compared to a two-coat or three-coat system with a slower drying finish coat. Additionally, faster dry times reduce the risk of dust, abrasive and other airborne contaminants from becoming embedded into the finished product. This study compares the handling time of three generic types of high performance finish coats cured under normal and cold/damp conditions, applied as two and three-coat systems, using traditional standardized test procedures as well as novel testing procedures designed to simulate actual handling and environmental conditions in the shop or field.

“Regulatory Update: Current and Emerging Trends in Occupational and Environmental Health” (PDF 98Kb) This paper takes a look at emerging environmental, health and safety issues that may impact painting contactors and facility owners. Specific topics include a summary of OSHA and EPA’s new and proposed revised regulations related to lead, paint, and construction. Information will be provided on EPA regulatory actions related to NAAQS Lead and the recent advanced notice of proposed rulemaking for Lead; Renovation, Repair, and Painting Program for Public and Commercial Buildings. Much of the information is taken directly from the respective agency’s published regulatory agenda, supplemented by anecdotal information gathered from various professional journals, seminars and conferences.

“Southern Nevada Water Authority-Polyurethane Lining Evaluation and Testing” (PDF 270Kb) The Southern Nevada Water Authority (SNWA) is a regional agency whose mission is to manage water resources and develop solutions that will ensure adequate future water supplies for the Las Vegas Valley. Its primary water resource is the Colorado River via Lake Mead. Since 2000, persistent droughts have resulted in decreasing Lake Mead water levels. To reduce Southern Nevada’s reliance on the Colorado River, SNWA has begun planning for the development of in-state groundwater resources north of Las Vegas. Initial planning efforts identified project specific requirements that could potentially justify the use of polyurethane lining systems in lieu of traditional cement mortar lining for over 200 miles of large diameter water transmission pipeline.

“Protective Coatings in 21st Century Nuclear Plants” (PDF 155Kb) The nuclear renaissance that is emerging in the United States will be based on new power plant designs from a variety of US and international sources. While the new plant designs will be based on the time tested and proven concepts of both the boiling water reactor (BWR) and the pressurized water reactor (PWR), the emphasis of the new plants will be on engineering designs that incorporate increased levels of redundancy in safety systems, and post-LOCA passive systems to move fluids about the reactor containment, thereby providing for long-term core cooling and decay heat removal, The new plant designs will include a strong emphasis on modular, off-site construction where more protective coatings will be applied in the fabrication shop. This paper will investigate: (1) the anticipated use and types of protective coatings in new reactor designs, (2) relate how the NRC is moving to regulate the technical requirements applicable to coating selection and testing, 3) describe how the design philosophies inherent in the new reactor plants will potentially affect the performance envelope of the planned coating systems, and (4) discuss possible methodologies for the long-term maintenance of the applied coating systems.

“Coating Problems Faced by Commercial Building Owners” (PDF 83Kb) Big box stores typically consist of a steel framework of structural columns and roof joists overlaid with roof decking. Walls are usually Single Wythe concrete masonry units (CMU), tilt up concrete panels, or colored block and brick. The CMU often consists of one or more block types – smooth face, split face, or scored block, all of which are painted. Smooth tilt up panels are painted or sealed, and colored block and brick are sealed. The walls may also be covered with an Exterior Insulation and Finish System (EIFS) or stucco, both of which are painted.
