(a) As used in this section the following words shall have the meanings ascribed to them as follows:
(1) CONTRACTOR. Any natural person, partnership, company, firm, corporation, association, limited liability company, cooperative, or other legal entity licensed by the Alabama State Licensing Board for General Contractors.
(2) NONRESIDENT CONTRACTOR. A contractor which is neither a. organized and existing under the laws of the State of Alabama, nor b. maintains its principal place of business in the State of Alabama. A nonresident contractor which has maintained a permanent branch office within the State of Alabama for at least five continuous years shall not thereafter be deemed to be a nonresident contractor so long as the contractor continues to maintain a branch office within Alabama.
(3) RETAINAGE. That money belonging to the contractor which has been retained by the awarding authority conditioned on final completion and acceptance of all work in connection with a project or projects by the contractor.
(b) Unless otherwise provided in the specifications, partial payments shall be made as the work progresses at the end of each calendar month, or as soon thereafter as practicable, on the estimates made and approved by the awarding authority. In preparing estimates, the material delivered on the site, materials suitably stored and insured off-site, and preparatory work done may be taken into consideration.
(c) In making the partial payments, there shall be retained not more than five percent of the estimated amount of work done and the value of materials stored on the site or suitably stored and insured off-site, and after 50 percent completion has been accomplished, no further retainage shall be withheld. The retainage as set out above shall be held until final completion and acceptance of all work covered by the contract unless the escrow or deposit arrangement described in subsections (f) and (g) is utilized. Provided, however, no retainage shall be withheld on contracts entered into by the Alabama Department of Transportation for the construction or maintenance of public highways, bridges, or roads.
(d) In addition to other requirements, a nonresident contractor shall satisfy the awarding authority that he or she has paid all taxes due and payable to the State of Alabama or any political subdivision thereof prior to receiving final payment for contract work. When maintenance periods are included in the contract covering highways and bridges or similar structures, the periods shall be considered a component part of the contract. On completion and acceptance of each separate building, public work, or other division of the contract on which a price is stated separately in the contract or can be separately ascertained, payment may be made in full, including the retained percentage thereof, less authorized deductions. Nothing in this section shall be interpreted to require the awarding authority to make full payment on an item of work when the item of work is an integral part of a complete improvement.
(e) In lieu of the retained amounts provided for in subsection (c) of this section, the awarding authority may provide in the specifications or contracts an alternate procedure for the maintenance of an escrow account as provided in subsection (f) or the depositing of security as provided in subsection (g).
(f) An escrow account, established pursuant to an escrow agreement, shall be entered into only on the following conditions:
(1) If the contractor shall have entered into more than one construction contract allowing for the maintenance of escrow accounts, the contractor may elect to combine the amounts held in lieu of retainage under each contract into one or more escrow accounts or may elect to establish a separate escrow account for each contract.
(2) Only state or national banks chartered within the State of Alabama or savings and loan associations domiciled in the State of Alabama may serve as an escrow agent.
(3) The escrow agent must limit the investment of funds held in escrow in lieu of retained amounts provided for in subsection (c) of this section to savings accounts, certificates of deposit or similar time deposit investments (which may, at the election of the contractor, be in an amount in excess of the maximum dollar amount of coverage by the Federal Deposit Insurance Corporation, the Federal Savings & Loan Insurance Corporation, or other similar agency), U.S. Treasury Bonds, U.S. Treasurer Notes, U.S. Treasurer Certificates of Indebtedness, U.S. Treasury Bills, bonds or notes of the State of Alabama or bonds of any political subdivision of the State of Alabama.
(4) As interest on all investments held in escrow becomes due, it shall be collected by the escrow agent and paid to the contractor.
(5) The escrow agent shall periodically acknowledge to the awarding authority and contractor the amount and value of the escrow account held by the escrow agent, and any additions to the escrow account by the awarding authority shall be reported immediately to the contractor. Withdrawals from the escrow account shall only be made subject to the written approval of the awarding authority.
(6) Upon default or overpayment, as determined by the awarding authority, of any contract or contracts subject to this procedure, and upon the written demand of the awarding authority, the escrow agent shall within 10 days deliver a cashier’s check to the awarding authority in the amount of the escrow account balance (subject to the redemption value of such investments at the time of disbursement) relating to the contract or contracts in default.
(7) The escrow account may be terminated upon completion and acceptance of the contract or contracts as provided in subsections (c) and (i) of this section.
(8) All fees and expenses of the escrow agent shall be paid by the contractor to the escrow agent and if not paid shall constitute a lien on the interest accruing to the escrow account and shall be paid therefrom.
(9) The escrow account shall constitute a specific pledge to the awarding authority, and the contractor shall not, except to his surety, otherwise assign, pledge, discount, sell or transfer his interest in said escrow account, the funds in which shall not be subject to levy, garnishment, attachment or any other process whatsoever.
(10) The form of the escrow agreement and provisions thereof in compliance herewith, as well as such other provisions as the awarding authority shall from time to time prescribe, shall be subject to written approval of the awarding authority. The approval of the escrow agreement by the awarding authority shall authorize the escrow agent to accept appointment in such capacity.
(11) The awarding authority shall not be liable to the contractor or his surety for the failure of the escrow agent to perform under the escrow agreement, or for the failure of any financial institution to honor investments issued by it which are held in the escrow account.
(g) The contractor may withdraw the whole or any part of the retainage upon deposit of securities only in accordance with the following procedures:
(1) The contractor shall deposit with the State Treasurer or the municipal or county official holding funds belonging to the contractor, the following readily negotiable security or any combination thereof in an amount at least equal to the amount withdrawn, the security shall be accepted at the time of deposit at market value but not in excess of par value:
a. U.S. Treasury Bonds, U.S. Treasury Notes, U.S. Treasury Certificates of Indebtedness, or U.S. Treasury Bills.

Certificates of deposit issued by savings and loan associations located in the State of Alabama, the accounts of which are insured by the Federal Deposit Insurance Corporation or the accounts of which are insured by a company approved by the state Savings and Loan Board and the certificates shall be made payable with accrued interest on demand. Any certificate from any of the savings and loan associations referred to in this paragraph shall not be for an amount in excess of the maximum dollar amount of coverage of the Federal Deposit Insurance Corporation.
(2) The agency or department of the state having jurisdiction over any public works contract shall notify the State Treasurer of the amount of the deposit required and shall also notify the State Treasurer when to release the deposit.
(3) The architect or engineer representing any municipality or county or the chair of any board, commission, or agency of any municipality or county shall notify the municipal or county official of the amount of deposit required and shall also notify the municipal or county official when to release the deposit.
(4) At the time of deposit of any security, the security may be endorsed and shall be accompanied by a conditional assignment to the public body designated as owner in the contract document, which assignment shall empower the State Treasurer, or the municipal or county official to negotiate the security at any time to the extent necessary to cause the fulfilling of the contract.
(5) Any interest or income due on any security deposited shall be paid to the contractor. If the deposit is in the form of coupon bonds, the coupons, as they respectively become due, shall be delivered to the contractor.
(6) In the event the contractor defaults in the performance of the contract or any portion of the contract, the securities deposited by the contractor in lieu of retainage and all interest, income, and coupons accruing on the securities, after default, may be sold by the state or any agency or department of the state, any municipality or county, or any board, commission, or agency of the municipality or county and the proceeds of the sale shall be used as if the proceeds represented the retainage provided for under the contract.
(h) All material and work covered by partial payments made shall become the sole property of the awarding authority, but the contractor shall not be relieved from the sole responsibility for the care and protection of materials and work upon which payments have been made, and for the restoration of any damaged work.
(i)(1) Upon the contractor’s completion and the awarding authority’s acceptance of all work required, the awarding authority shall pay the amount due the contractor upon the contractor’s presentation of the following items:

c. Proof of advertisement as provided by law.
(2) Such payment shall become due and owing 40 days after all the requirements of subdivision (1) are fulfilled.

The interest rate shall be the legal amount currently charged by the State of Alabama Department of Revenue. Interest shall accrue on the day following the later date described above and shall be paid from the same fund or source from which the contract principal is paid.
(j) If the Department of Transportation or a county awarding authority shall determine that there has been overpayment to a contractor on a contract award pursuant to this chapter, the Department of Transportation or the county awarding authority shall provide written notice of the overpayment to the contractor and the contractor shall remit the overpayment to the Department of Transportation or the county awarding authority within 120 days of receipt of the demand. If the contractor fails to remit payment in full of the overpayment within 120 days of receipt of demand, the contractor shall be disqualified from bidding as a prime contractor or from performing work as a subcontractor on any future Department of Transportation contract or county contract for the construction or maintenance of public highways, bridges, or roads until the overpayment is made.
