For distributors and material suppliers
Know who is about to buy, and who they are.
You need all three axes, and the third one is the point: who will do the work.
The same logic applies to every product category. Knowing that a project will need mechanical equipment is the first measured example, not the only use case. Knowing that the general contractor's three most likely mechanical firms are A, B and C — and that one of them is right 78.4% of the time — tells your rep which door to knock on, weeks before the permit is filed.
After the permit is issued, the same data becomes a purchase-ready list: in Philadelphia, roughly 880 permits are issued each week, 87% of them naming the contractor.
Practical next step
Use the public timeline to identify a project worth researching, confirm the current permit with the issuing authority, and apply your own commercial qualification before outreach. The page describes a workflow for this role; it does not promise access to a specific job or decision-maker.
Why the evidence remains local
Permit labels, filing habits and project timing vary by jurisdiction. A frequency shown for Philadelphia is evidence for Philadelphia and its stated sample, not a performance claim for another market.
