In 2003 Connecticut Department of Transportation (DOT) conducted a study to quantify the throughput and cost savings potential of a PAS two-coat system versus a three-coat system. The study showed that a PAS two-coat system had a 31% increase in productivity and direct cost savings of approximately $6 per square foot, with indirect cost savings of $18 per square foot when including the benefits of reduced traffic congestion.17 PAS two-coat systems utilize a zinc-rich primer for galvanic protection; the epoxy and polyurethane layers are replaced by a high-build PAS topcoat.
The presentation is meant to be a guide for owners, contractors, and engineering/inspection teams – from the perspective of a licensed resident engineer – on how to be successful bidding, scheduling, coordinating, and performing work on a large scale and high-profile coatings contract. Contractors will gain insight into aspects of the project that may be outside their specialty and see examples of unanticipated issues that develop during a major project that should be considered when preparing a bid.
This study is a result of analyzing the data and statistics from the Brooklyn Bridge project collected during lead paint removal operation. The $508 million Brooklyn Bridge Contract 6, which is still ongoing, commenced in 2010 as a part of New York City Department of Transportation’s (NYCDOT) $2.6 billion East River Bridges Capital Program.
