What is recorded here
Multiple filings, one stable building identifier.

The records below are grouped because they publish BIN 3179705. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 2 alteration filing. Its latest status categories are 2 approved. Each filing page preserves its own status, dates, scope and source identifier.
