DOB Debuts Interactive Construction Map

By Jonathan Sperling

Thanks to a new tool from the Department of Buildings, you can find out exactly what’s going on above the scaffolding that just went up on your block.  

At more than 6,300 other work sites, too.

The DOB launched an interactive Active Major Construction map that allows curious residents to view all active major construction sites, with buildings on the map categorized by square footage, estimated cost and the proposed number of units with larger points denoting higher values.

The map depicts New Building and Alteration Type 1 Enlargement permits.

Clicking on a point on the map gives the user more details and interactive filters, as well as a direct link to the construction site’s permit info via the DOB’s Building Information System.

For those into rankings, the map also displays a daily Top 10 list of active sites boasting the most square footage, the most expensive, the tallest and most dwelling units. Top 10 bar graphs display general contractors with the most active citywide square footage and cost, as well as occupancy information, according to the DOB.

As of Thursday, Aug. 30, the map plotted 6,339 active construction site permits, 179,428,780 total square feet of construction and 118,428 proposed dwelling units.

In Queens, Long Island City and Astoria stands out as a hotspot of construction, with scores of dots plotted along the waterfront. A high concentration of new development is also evident in Flushing and Jamaica.
