Legacy SSPC Conference Papers
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 presentation will offer best practices maintenance advice to the user of Abrasive Blasting Equipment, providing a ready-made checklist to guide the user through an operating year.
The use of sustainable materials in the flooring market has gained widespread interest in recent years. Bio based raw materials contribute significantly to these efforts and are used to prepare environmentally friendly coatings. Castor oil-based emulsions are used as polyols in waterborne polyurethane coatings. These systems have outstanding chemical resistance and good durability. But they have inherent issues like very short pot life, poor appearance / flow properties, and delayed early hardness development.
The Farm Security and Rural Investment Act of 2002 (FSRIA) and the Food, Conservation and energy Act of 2008 (FCEA) established the BioPreferred Program which requires Federal agencies o give preference to biobased products when making purchases.
In early 2009 the City of Sunnyvale in Northern California put out to bid a repaint of three five‐million gallon water tank exteriors. The tanks existing coatings qualified as leadbased paint with average concentrations of 120,000ppm or 12% lead. The three tanks were successfully abrasive blasted to an SSPC SP‐10 and recoated with a zinc/acrylic system without erection of an SSPC Guide 6 Type 1A enshrouding containment. This paper tells the story of how this was done successfully using standard but not often seen work practices, even though the project was right next door to an elementary school and multi‐family residential developments and so had to perform to the strictest levels of environmental standards.
The aim of this case study is to identify the challenges of blasting a large bridge, blasting at long distances from equipment, and painting on a maintenance program vs the whole bridge. Then we provide recommendations and suggestions how to make it profitable, based on real-life project experience.
The Sunshine Skyway Cable Stay Bridge is the signature bridge in the State of Florida. During 2004 the decision was made to repaint the stay cables for corrosion protection and aesthetic issues. The authors participated in a coatings condition assessment, plan development for refurbishing the coating system, and project execution. This paper identifies areas that made the Sunshine Skyway Bridge a challenging project such as: coatings condition assessment, paint specifications, access, containment system, execution, and final acceptance.
Brief Background Throughout the last decades, coatings science has incorporated very versatile inorganic materials into organic coating to form the inorganic/organic hybrid coating systems. Combining various organic and inorganic constituents in combination with different preparation and processing methods, very versatile materials can be produced for optical, structural and coatings applications. The hybrid products have combined the properties of the inorganic materials, i.e., hardness, durability, and thermal stability, and organic polymers, i.e., flexibility and toughness.
With over 5 million respirator users in approximately 1.3 million United States workplaces, Respiratory Protection is a perennial “Top 5” most cited OSHA violation. 2013 saw 3,995 violations, taking fourth place and increasing 64% from 2012 (also the fourth-most cited standard) (1). The number one reason for citation – lack of a written program. 29CFR1910.134 is the OSHA standard that covers Respiratory Protection (2). A written program is required in any workplace where respirators are necessary to protect the health of the employee or whenever respirators are required by the employer.
This paper identifies the problems and challenges with the making of the Bridge Brothers documentary, from its inception to the distribution. It will discuss the intent of the film from the perspective of the filmmakers, and the bridge painting contractor. The documentary explains the importance of re-painting and rehabilitating our nation’s bridges, while exploring life on the bridge for the industrial bridge painters (Bridge Brothers) on the Commodore Barry and Walt Whitman Bridges in Philadelphia.
As an island nation, Japan is particularly dependent on the good health of its bridges to connect its different regions for commercial activities. In order to reduce maintenance cost and downtime for bridges, Japanese road authorities have looked to the use of longer lasting premium materials of construction.
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.
