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

The records below are grouped because they publish BIN 1045572. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 4 alteration filing. Its latest status categories are 4 approved. Each filing page preserves its own status, dates, scope and source identifier.
