In New York the client is rarely the only decision maker
A very large share of New York construction work happens inside buildings that someone else manages. An apartment renovation needs the building to agree as well as the owner, with alteration paperwork, deposits, insurance requirements and a board decision that arrives on its own timetable. A commercial fit-out needs the landlord and the building management. Even straightforward work is gated by protection requirements, work hours and elevator access.
That reshapes the pipeline. A job can be entirely agreed with the paying client and still be months from starting, and the party who has to be chased is not the client. Firms that treat building approval as an explicit stage with an owner and dated tasks convert far more of these projects, because somebody is actually pushing the paperwork instead of everyone waiting politely.
Site access is a paperwork problem
Certificates of insurance are the single most common reason a New York crew stands down on a morning it was supposed to start. Requirements from managing agents and general contractors are detailed, they expire, and nobody notices until the lobby turns the crew away. A queue with owners, turnaround targets and renewal tasks ahead of expiry removes an entire category of avoidable loss.
