General Fund Infrastructure · Phased execution against the gap

$3.7T ASCE backlog → $0.9T residual by Year 25

The 25-year buildout clears approximately 75% of the documented 2025 ASCE infrastructure backlog. Annual envelopes ramp through Civilization-Premium ramp (Era 1), peak in backlog buildout (Era 2), and taper through tail completion (Era 3) before the program drops to maintenance steady-state.
