Quick answer

Alaska's construction payment article, AS 36.90.200 to 36.90.290, covers public work and sets no retainage percentage. The state or political subdivision pays the prime contractor interest on retainage from the date a pay request is approved until payment, and the prime pays each subcontractor its retainage within eight working days after receiving final payment. Private work has no statutory rule.

Alaska's construction payment article, AS 36.90.200 to 36.90.290, applies to public construction and public works contracts of the state and its political subdivisions. It sets no retainage rule for private work, so a private contract governs.

Retainage cap
AS 36.90.200 to 36.90.290 set no maximum retainage percentage. They require the state or political subdivision to pay the prime contractor interest on retainage, including warranty retainage, and require every public subcontract to carry clauses that pass retainage down within eight working days. A political subdivision with a population of 500 or less is exempt from the interest on retainage, and a contract provision that waives a provision of the article is void (AS 36.90.270).
Deadline
8 days
Final payment to the prime contractor by the state or political subdivision (or the end of the AS 36.25.020(b) notice period, if later). The eight working days are the prime contractor's deadline for paying each subcontractor its retainage; the article sets no date for the owner's own release of retainage.
What the statute says
The state or a political subdivision of the state shall pay to the prime contractor interest on retainage, including warranty retainage, on a contract for public construction or public works at an interest rate that is equal to the amount set out in AS 45.45.010 (a). Interest on retainage accrues from the date of approval of a pay request until the date of payment to the contractor.

Who this applies to

Alaska's rules sit in one article of Title 36, AS 36.90.200 to 36.90.290, and that article is written for public construction and public works contracts of the state and its political subdivisions [2]. Under AS 36.90.265, it applies to a political subdivision's contract if the subdivision has entered into a written contract with the state for the state to provide funds for the project [2]. Two relationships are covered: the public owner and its prime contractor, and the prime contractor and its subcontractors [1].

On a private job, no statute caps retainage or sets a release date, so the contract governs [2].

What the rule says

Alaska does not limit how much retainage a public owner may hold. The article works on the cost of holding it and on how quickly it moves down the chain.

Interest from the owner. Under AS 36.90.250(a), the state or political subdivision pays the prime contractor interest on retainage, warranty retainage included, at the rate set in AS 45.45.010(a) [1]. Interest runs from the day a pay request is approved until the day the contractor is paid [1]. A political subdivision with a population of 500 or less is exempt from this interest [1].

Pass-down to subcontractors. Every public subcontract must carry clauses that require the prime to pay the subcontractor all retainage due within eight working days [1] after the prime receives final payment from the public owner, or after the notice period under AS 36.25.020(b) expires, whichever is later [1]. The same required clauses provide interest on retainage withheld from subcontractors and their suppliers at the same statutory rate [1].

The eight working days are the prime contractor's deadline. No section of the article names a separate deadline for the public owner's release of retainage to the prime, and the late-payment interest in AS 36.90.200 does not apply to retainage [1].
