Ground broke Tuesday on Sol on Park, a 229-unit affordable housing development built on NYCHA-owned land in the Bronx, under the agency's Permanent Affordability Commitment Together program.

The city's own announcement — first reported by NYC.gov — names the Mamdani administration, NYCHA, and its private development partners as co-hosts of the groundbreaking, part of the broader push to convert NYCHA land into financed affordable housing without selling the underlying property.

This is the delivery end of a pipeline The RFI Wire has tracked all year: NYCHA takes land it already owns, brings in a private developer and lender, and gets new units built without City Council capital dollars. For GCs and subs, PACT groundbreakings are where the pipeline becomes real work — excavation, foundations, and vertical construction are about to start on a site that spent a year or more as a financing story.

The mayor's office closed financing on this exact site back in July, so the roughly two-month gap between closing and groundbreaking is itself useful data: that is about how long it now takes a PACT deal to go from paper to dirt. Subs bidding future PACT sites can use that lag to plan mobilization.

Contractors chasing NYCHA-adjacent work should watch the agency's PACT solicitation page for the next site in this pipeline — financing closings are now a leading indicator for bid postings 60 to 90 days out.
