Installation of FRP pile jackets at bridge sites in Portsmouth, New Hampshire.  The project consisted of demolition of existing concrete, pile repairs, replacement/repair of cathodic protection system, HP blasting of steel to WJ-3 standards, and pumping of marine epoxy grout.  Roadway closure restrictions limited work to be preformed from sectional work barge,  An eight foot tidal range caused exceptionally fast-moving current within the waterways of the Piscataqua Estuary was challenging to complete this project.
