LAS VEGAS—Complex containment, strict schedules and rigorous regulations earned eight painting projects top honors as SSPC 2015 opened Tuesday (Feb. 3) in Las Vegas, NV.

SSPC kicked off its annual conference and exhibition with its awards luncheon, where outgoing Executive Director Bill Shoup and President James R. King Jr. also updated members on the society's current numbers.

This year's award-winning projects were fraught with danger, difficulty and drama.

Crews scrambled around frequent bridge openings high over waterways; navigated wind-buffeted access structures; volunteered their time for historic military projects; designed innovative containment to protect wildlife; and braved a soaking-wet, cold rock-tunnel penstock 80 feet underneath a Canadian generating station.

The society also honored outstanding individuals whose careers reflect decades of service to the industry.

Structure Awards

The Structure Award winners, listed below, will also be featured in a photo essay in an upcoming issue of JPCL.

George Campbell Award

The George Campbell Award honors a difficult or complex industrial or commercial coatings project. Challenges may include extreme environmental conditions, time constraints, limited access or high traffic, complex structural components, or coordination with multiple trades or subcontractors.

The award is named for the late George Campbell, founder of Campbell Painting Company in New York.

Brooklyn Bridge: New York, NY

Owner: New York City Department of Transportation
Contractor/Applicator: Ahern Painting Contractors
Coating Supplier: Devoe High Performance Coatings

Once an avenue for P.T. Barnum's elephants to march into town, the Brooklyn Bridge—a 132-year-old hybrid stayed/suspension span—carries 120,000 vehicles and 7,000 pedestrians over the East River every day.

Traffic, existing lead coatings, outside agency coordination and sheer size necessitated a multi-tiered approach to clean and repaint the structure's 4.2 million square feet of steel beams, braces and cables.

For work on the Brooklyn Bridge, a complex system of hoses and duct work was designed, stretching from the SSPC Class1A containment to a custom grit recycling unit more than 1,200 feet away.

The project required coordination with the City of New York, the Boroughs of Manhattan and Brooklyn, City Hall, 1 Police Plaza, NYCDOT and the U.S. Coast Guard.

Abating the existing lead coatings created another set of challenges. The bridge's age and weight limitations, along with a requirement to keep all three lanes open for traffic, nixed any chance of placing abatement vehicles on the roadway. Therefore, a complex system of hoses and duct work was designed, stretching from the SSPC Class1A containment to a custom grit recycling unit more than 1,200 feet away.

A 20,000-panel system of under-bridge platforms was used for work on the 3,455-foot-long structure. After abrasive blast cleaning to a Near-White (SSPC-SP 10) finish, the steelwork was repainted with a four-coat system consisting of an organic zinc-rich epoxy primer, a pre-prime sealer coat, an epoxy intermediate, and an aliphatic urethane gloss finish.

The project started in January 2010 and was completed Oct. 1, 2014.

Fremont Bridge: Seattle, WA

Owner: Seattle Department of Transportation
Contractor/Applicator: Purcell Painting & Coatings LLC
Coating Supplier: The Sherwin-Williams Company

The low 30-foot vessel clearance of the Fremont Bridge, a double-leaf bascule structure spanning a heavily used navigable waterway, challenged crews to deal with frequent drawbridge interruptions and complex loading conditions.

The 97-year-old bridge, which connects Seattle's Fremont and Queen Anne neighborhoods, was last cleaned and coated in 1970. In this project, the structure was spot repaired and coated with a moisture-cured system to protect against the area's harsh wind and rain.

While working on one of the busiest bascule bridges in the world, the contractor's 37-person team had to quickly secure its work, vacuum up paint chips, and clear the bridge nearly three dozen times per day to allow it to open for marine traffic.

While working on one of the busiest bascule bridges in the world, the contractor's 37-person team had to quickly secure its work, vacuum up paint chips, and clear the bridge nearly three dozen times per day to allow the span to open for marine traffic.

A suspended platform system had to be designed to support the worker and debris load while the bridge was down, but also keep the platform stable when the bridge was raised. Engineers were also concerned that high winds would slam the platform into the underside of the bridge as it lifted vertically with the raising structure.

Therefore, a series of rigid anti-uplift and horizontal bracing members was installed to hold the deck in place, while intentionally passing the load to the stronger framing points of the bridge substructure.

The project started April 7, 2014, and was completed Dec. 30, 2014.

William Johnson Award

The William Johnson Award recognizes outstanding achievement in aesthetic merit in industrial or commercial coatings work. Criteria include color, gloss, texture, and how the coating complements the environment while enhancing the structure.

The award is named for a late consultant with KTA-Tator Inc., whose work in coatings formulation, failure analysis, and surface preparation was instrumental in advancing the industry.

Rainbow Swash LNG Tank: Boston, MA

Owner: National Grid
Contractor/Applicator: John W. Egan Company Inc.
Coating Supplier: The Sherwin-Williams Company

At 139 feet tall and 152 feet in diameter, the Rainbow Swash natural gas storage tank isn't just a Boston landmark—it's the largest copyrighted work of art in the world.

Overcoating the tank's 73,374-square-foot exterior required detailed application of a tinted epoxy basecoat and polyurethane topcoats to restore the art without compromising the original design work, which was commissioned in 1971 and created by Corita Kent.

The Rainbow Swash is the largest copyrighted work of art in the world.

(The original tank was demolished in 1992, but the "Rainbow Swash" was recreated on an adjacent tank.)

Surface preparation included removing the existing clear coat and surface contamination with waterjet cleaning to SSPC-SP WJ-4/NACE WJ-4; power tool-cleaning localized areas of corrosion to SSPC-SP 3; and abrading the existing coatings.

The tank exterior was spot-primed with a fast-cure polyamide epoxy before receiving a three-coat system consisting of a fast-cure polyamide epoxy, an acrylic polyurethane, and a clear coat urethane.

The project started July 7, 2014, and was completed Oct. 3, 2014.

E. Crone Knoy Award
Named for the late founder and president of Tank Industry Consultants, the E. Crone Knoy Award acknowledges coatings work that demonstrates innovation, durability or utility.
The award recognizes outstanding achievement that may include excellence in craftsmanship, execution of work, or the use of state-of-the-art techniques and products to creatively solve a problem or provide long-term service.
Mamquam Generating Station: Squamish, British Columbia
Owner: Atlantic Power
Contractor/Applicator: Certified Coating Specialists Inc.
Coating Supplier: Carboline Co.

This project included cleaning and recoating the exterior of the Mamquam Generating Station's 1,750-foot penstock, located 80 feet underground.
Encased in a rock tunnel, working space ranged from five to 15 feet. All of the equipment, scaffolding and personnel had to be transported down a vertical shaft via ladder access.
Workers faced uneven ground, changing elevation, and a constant flow of water; they changed clothes three to four times per shift in order to stay warm and dry.


Workers had to transport equipment 80 feet underground, where they worked in a cold, constant flow of water.

The penstock exterior was scraped to remove loose rust before it was abrasive blast-cleaned to a Near-White finish (SSPC-SP 10). Afterward, the surface had to be pressure washed and squeegeed to remove abrasive stuck to the penstock due to constant moisture sweating. Three coats of an epoxy were spray- and backroll-applied.

The project started in January 2014 and was completed in April 2014.

Mokelumne Aqueducts: Contra Costa and San Joaquin Counties, CA
Owner: East Bay Municipal Utility District
Contractor/Applicator: Abhe & Svoboda Inc.
Coating Supplier: Carboline Co.

About 1.3 million people rely on three Mokelumne Aqueducts to carry water 90 miles from the Sierra Nevada Mountains to San Francisco's East Bay communities.
A 10-mile portion of the system's steel pipelines are above ground, where they cross four sloughs—sensitive bodies of water that are home to numerous protected wildlife species.
Environmental concerns and strict permitting required an innovative approach to abate the original red lead/aluminum paint system. The team came up with a unique floating containment system that could navigate shallow wetlands waterways influenced by tides.
The pipe barrel was abrasive blast-cleaned to Near-White (SSPC-SP 10) and coated with an untopcoated inorganic zinc. The steel supports received a three-coat system consisting of an inorganic zinc, an epoxy and a polyurethane.

Cleaning and coating the Mokelumne Aqueducts required a unique floating containment system.
The project started July 1, 2011, and was completed Oct. 21, 2013.
