Photos: construction progress, below-grade, at B4 and B15 sites

The construction of B4 (18 Sixth Avenue) and B15 (664 Pacific Street) encroaches on Atlantic and Sixth avenues, significantly, but what's going on behind the fences? What's the product of all those after-hours construction approvals? I took a few photos last week, which shows progress below-grade.

Most notably, there's a (partial?) concrete pour at B4, built at the northeast flank of the Barclays Center, and a deep excavation catercorner at B15, which will contain a school in its lower floors, and below grade.

The 511-foot B4--the largest tower so far, and likely the second-largest in the project--may be finished in 2022, while B15 should be finished in 2021.

B15 photos

The B15 site, looking north through a hole in the fence on Dean Street, east of Sixth Avenue. It's probably not super-peaceful to live in the apartment building at rear, with the balconies, or at the apartment building at right foreground, mostly a blank wall now.
