Marine Borer Investigation at FDR Drive

Marine Borer Investigation at FDR Drive
Project Overview: 
McLaren completed the underwater inspection of approximately 12 miles of relieving platform along the FDR and Harlem River Drives, including underwater condition survey, below water inspection and assessment of 63,400 piles, marine borer identification, and destructive testing and evaluation. This work spanned nearly the entire length of the East side of Manhattan from the South Street Seaport to 181st Street.
McLaren's Role: 
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.
