Summary of 300' Concrete Pier Inspection and Assessment Report

This document is a waterfront facility inspection and assessment report for the 300' Concrete Pier (RPUID 16769) located at USCG SFO Fort Macon in Atlantic Beach, North Carolina. The pier is a fixed concrete platform supported by cast-in-place concrete pile caps, beams, and precast concrete piles, measuring 300 feet long by 20 feet wide. It functions as a loading/unload platform for the cutter's buoy tending operations and can support a concentrated load limit of 20,000 pounds. The inspection was conducted as part of a rehabilitation project that was recently terminated due to contractor default. The pier received a Condition Assessment Index Rating of "Poor" with a Condition Index (CI) of 67, indicating significant structural deterioration requiring repairs.

The assessment identifies critical repairs needed across multiple structural elements with a total estimated construction cost of $3,750,700. Short-term, high-risk repairs include underdeck corrosion spall repairs ($444,900), top deck repairs involving removal and restoration of sections with curing cracks ($1,370,900), edge beam corrosion spall repairs ($444,900), and pile cap corrosion spall repairs ($55,700). Additional short-term, medium-risk repairs include a ramp corrosion spall repair ($7,500). The document recommends installing a temporary steel plate in the buoy off-load area to distribute loads during the repair process. The pier's remaining service life without repairs is 5 years; with repairs, it extends to 10+ years. The next inspection is scheduled for 2028. Operational restrictions recommend limiting access between Bents 20 and 21, with recommendations to add slat piles to the buoy loading area to distribute concentrated loads.
