Marine Borer Investigation at FDR Drive

McLaren inspected a multitude of waterfront structures of different ages and construction types, including low-level relieving platforms (timber and concrete), high-level platforms (timber, steel, and concrete), steel sheet pile bulkheads, timber sheet pile bulkheads, concrete gravity seawalls, timber crib walls, and riprap embankments The condition survey was comprehensive, and was broken down into "location" and "segments." Destructive testing Level II timber cores were retrieved on hundreds of timber piles, and submitted by McLaren to testing labs to assess marine borer activity and creosote retention. The results of the inspection and studies are presented in detailed reports.
