Section L - Instructions, Conditions, and Notices to Offerors and Respondents

L.04 - Proposal Composition Requirements and Instructions

L.04.A. In order to assess the Offeror's Qualifications, the Offeror shall submit a proposal in accordance with the instructions contained in this provision. The Offeror is advised to carefully read the entire Solicitation.

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 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.04.B (a). Due to the schedule and security requirements associated with this solicitation, all proposals 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) proposals.

L.04.C (a) Instructions concerning the content and organization of the proposal.

Each Offeror shall propose to satisfy the requirement as set forth in this solicitation. The proposals will be evaluated on the basis of content (what is written in the documents). No extraneous information will be used for evaluation purposes with the exception of past performance.

The USIBWC may utilize written and/or verbal communications with past performance references and/or information available in the Past Performance Information Retrieval System (PPIRS).

L.04.C (b) Each Offeror is responsible for including sufficient details to permit a complete and accurate evaluation of the proposal from both a technical and management standpoint.

The Offeror shall be prepared to provide all services as described in their proposal. In the case of a conflict between the Offeror's proposal and the PWS, the PWS takes precedence.

L.04.C (c) Proposals shall be as brief as possible but sufficiently detailed to completely and adequately describe what is proposed.

Document Number: 191BWC26R0001 PROCESSED Page 5 of 6

L.04.C (d) Offerors shall comply with all requirements of the proposal submission instructions. Deviations shall be fully explained;

however, inclusion of cost/price information with the technical/management volume of the proposal is not considered an acceptable deviation.

Each Offeror is cautioned that "parroting" of the requirements with a statement of intent to perform does not reveal the Offeror's understanding of the problem or his capability to solve it. The inclusion of filler material from previous proposals or commercial applications shall be avoided unless there is a direct application to the objective of this solicitation.

L.04.C (e) Unless the Offeror inserts a longer period of time on the Standard Form (SF) 33, page 1, block 12, proposals will remain valid for a period of 120 calendar days from the date specified for receipt of proposals in Block 9.

1) TECHNICAL PROPOSAL, VOLUME I: The technical volume shall contain sufficient quantitative and qualitative details (without reference to cost or price) to permit a complete and accurate evaluation of the proposal from strictly a technical viewpoint. Offerors are cautioned to keep in mind the criteria set forth in Section M against which the proposals will be evaluated. Proposals shall be organized into separate sections responding to each merit factor in the order listed below. The Technical Volume shall contain:

a. Factor 1: Past performance of wastewater treatment plant operations and maintenance service contract (s).

b. Factor 2: Specialized experience and technical competence in secondary activated sludge with aeration tanks wastewater treatment plant operations and maintenance.

g. Factor 7: Supervisory Control and Data Acquisition (SCADA) experience. The contractor shall submit a self-attestation that their Corporate System has implemented or will implement all the agency designated security controls selected from NIST 800-171.

The Technical Volume shall contain an addendum consisting of the proposed Phase-In Plan to provide for (1) a complete and orderly phase-in, (2) a timetable for orderly assumptions of each responsibility, as required, (3) performance of all functions, (4) adequate resources, and (5) plans covering key functional areas during the phase-in period.

(2) The Phase-In Plan will be evaluated. An Acceptable or higher rated Phase-In Plan is mandatory and will be evaluated during the initial evaluation.
