After park officials were alerted, the girders, which poked through the sand on the beach, were barricaded for “public safety” and inspection.
“Our engineers and designers made several inspections, completed a survey and are working on a solution,” Pat Kirshner, vice president of capital planning and construction at Brooklyn Bridge Park said in a statement.
“We will be pulling the three piles out of the beach shortly,” she said.
The small beach at Pier 4 opened last month along with basketball, bocce and shuffleboard courts and playgrounds at Pier 2 in Brooklyn Bridge Park.
Hundreds of cubic yards of debris were removed from the site to construct the natural-looking shoreline. The steel beams were left over from old bulkhead.
The work on the piles will begin early Wednesday morning during low tide and take a few hours to complete, spokeswoman Teresa Gonzalez said.
