It’s pile driving and drilling time again in the Burg as two buildings that have been moving toward construction look like they’re getting underway. The project on the right is at 187 N. 8th Street at N. 8th and Driggs, on the site of the Wonder Foods building that was demolished about year ago. It will be a six-story building with 49 units. The other is the site of the former Beach Russ building on the street that is rapidly becoming Brooklyn’s Construction Site Row, Union Avenue. 554 Union will have 100 units. Both machines look like they’re going to give the neighborhood and the neighbors a good, hard pounding.
