SECTION I - CONTRACT CLAUSES

The following have been modified:

52.228-15

52.228-15 – Performance and Payment Bonds -- Construction (Oct 2010)

(a) Definitions. As used in this clause --

“Original contract price” means the award price of the contract; or, for requirements contracts, the price payable for the estimated total quantity; or, for indefinite-quantity contracts, the price payable for the specified minimum quantity. Original contract price does not include the price of any options, except those options exercised at the time of contract award.

(b) Amount of required bonds. Unless the resulting contract price is $150,000 or less, the successful offeror shall furnish performance and payment bonds to the Contracting Officer as follows:

(1) Performance Bonds (Standard Form 25). The penal amount of performance bonds shall be 100 percent of the original contract price for CLINS 0003-0008 and is due within 10 calendar days after receiving the Notice to

Proceed (NTP) for CLINS 0003-0008,

(2) Payment Bonds (Standard Form 25-A). The penal amount of payment bonds shall be 100 percent of the original contract price for CLINS 0003-0008 and is due within 10 calendar days after receiving the Notice to Proceed (NTP) for CLINS 0003-0008.

(3) Additional bond protection. (i) The Government may require additional performance and payment bond protection if the contract price for any portion of the construction work is increased. The increase in protection generally will equal 100 percent of the increase in contract price for construction work.

(ii) The Government may secure the additional protection by directing the Contractor to increase the penal amount of the existing bond or to obtain an additional bond.

(c) Furnishing executed bonds. The Contractor shall furnish all executed bonds, including any necessary reinsurance agreements, to the Contracting Officer, within the time period specified in the Bid Guarantee provision of the solicitation, or otherwise specified by the Contracting Officer, but in any event, before starting work.

(d) Surety or other security for bonds. The bonds shall be in the form of firm commitment, supported by corporate sureties whose names appear on the list contained in Treasury Department Circular 570, individual sureties, or by other acceptable security such as postal money order, certified check, cashier’s check, irrevocable letter of credit, or, in accordance with Treasury Department regulations, certain bonds or notes of the United States. Treasury Circular

570 is published in the Federal Register or may be obtained from the U.S. Department of Treasury, Financial

Management Service, Surety Bond Branch, 3700 East West Highway, Room 6F01, Hyattsville, MD 20782. Or via the internet at http://www.fms.treas.gov/c570/ .

(e) Notice of subcontractor waiver of protection (40 U.S.C. 3133(c)). Any waiver of the right to sue on the payment bond is void unless it is in writing, signed by the person whose right is waived, and executed after such person has first furnished labor or material for use in the performance of the contract.
