To safeguard sensitive procurement data, the U.S. Section of the International Boundary and Water Commission (USIBWC) utilizes its secure FEDRAMP Microsoft SharePoint environment for the submission of bids and proposals. SharePoint is a cloud-based platform that integrates with Microsoft 365 and leverages enterprise-level security protocols, including data encryption at rest and in transit, multi-factor authentication (MFA), and role-based access controls. When folders are shared with external users for bid submission, access is limited to specific, authenticated email addresses. External users must verify their identity through a

Document Number: 191BWC26B0001 PROCESSED Page 5 of 7 secure email link and authentication code prior to gaining access, ensuring that only authorized parties can view or upload content.

Permissions can be tailored (view or edit), and access can be revoked or expire automatically. All activities on the platform are logged and monitored, providing traceability and accountability. These measures collectively ensure that procurement documents are handled with confidentiality, integrity, and compliance with federal IT security standards.

L.02.B. Due to the schedule and security requirements associated with this solicitation, all bids must be submitted exclusively via the U.S. IBWC's secure Microsoft SharePoint portal. This replaces prior instructions for submitting hard copy or physical media (DVD/ CD) bids.

(1) For bids that exceed $150,000, the bidder shall furnish a guarantee, assuring that the bidder will not withdraw a bid within the period specified for acceptance and will execute a written contract and furnish required bonds and insurance agreement within the period specified therefore, in an amount of not less than 20 percent of the bid price or two hundred sixty thousand dollars ($260,000) whichever is lesser.

(a)The bid guarantee penalty may be expressed in terms of a percentage of the bid price or may be expressed in dollars and cents.

SF-24, Bid Bond is located at the following website: http://www.gsa.gov/portal/forms/type/SF.

Document Number: 191BWC26B0001 PROCESSED Page 6 of 7

(c) Requirements for executive of surety bonds. Each surety company bond (bid, performance, or payment), that purports to have been executed by an agent or attorney-in-fact for the corporate surety, is required to have submitted with it a power of attorney to the signatory agent or attorney-in-fact, and

(1) be executed by the corporate surety upon a reasonable proximate to the date of the bond, or

(2) the power of attorney shall be accompanied by a certification of the surety to the effect that the power of attorney was in full force and effect upon a date reasonably proximate to the date of the bond.

(d) Individual Sureties.

(1) If individual surety bonds are furnished either for bid guarantee or for payment and performance bonds, the individual sureties must submit with their bonds proof of ownership and value of the assets which they claim in their net worth. The Government’s preferred method of proof is to have a statement of net worth prepared by a certified public accountant in accordance with generally accepted accounting principles. The statement of net worth on the SF-28, Affidavit of Individual Surety, is not in itself sufficient and will not be accepted absent of additional proof of value and ownership.

(2) Bidders are also cautioned that individual sureties must provide complete and detailed information in block 9 of the SF-28 concerning other contracts on which they have provided bonds. This information should include contract number, contract location, amount and type of bond and telephone number of the involved contracting officer.

(3) Failure to provide the proof and information requested above will cause delays to the start of the construction for which the contractor must bear the responsibility and may result in rejection of a bid or termination of contact for failure to provide adequate bonds.
