The Board of the New York City Housing Authority has approved a $2.3 million contract to repair the exterior brickwork of Williams Plaza Houses, a public housing development in the Williamsburg section of Brooklyn.

"This is major renovation work that not only includes the replacement of brickwork, but new horizontal expansion joints, rebuilding the existing vertical expansion joints and cleaning the facades of the buildings," said NYCHA Chairman Tino Hernandez.

The contract was awarded to Sumrart Restoration Corp, of Bellerose, N.Y., and is expected to take about a year to complete.

Williams Plaza Houses has five buildings, 14 and 21-stories tall with 577 apartments housing approximately 1,674 people. Completed in April 1964, the 5.58-acre site is bordered by Roebling Street, Broadway, Division and Marcy Avenues.
