Alabama public retainage and private contract holdback
Alabama public construction retainage is planned at 5% under Ala. Code § 39-2-12, with release often about 45 days after completion. Prompt pay for private work is a different article (Ala. Code § 8-29-1 et seq.). Mixing those two is how subs over-model cash on a private job that still holds 10%.
Private retainage is whatever the subcontract says. There is no Alabama private cap equivalent to Massachusetts § 29F. Prime-to-sub on public work is typically 7 days after the prime is paid.
If the job is Alabama public, start the retainage calculator at 5%. If it is private, use the subcontract rate and treat the G702-style Line 5 as cumulative — Alabama GCs still catch a pay app that restarts retainage each month.
