Abstract:
A variety of destructive and nondestructive tests were used to evaluate existing conditions and the extent of deterioration of Brandywine Shoal Lighthouse. Founded atop a hazardous shoal next to a busy shipping channel in Delaware Bay, this historic concrete structure has deteriorated severely in the harsh marine environment. The recommended repairs utilize the full spectrum of concrete types, including shotcrete, preplaced-aggregate, tremie, precast and cast-in-place.
