1.5 Offeror's Responsibility. It is the offeror's responsibility to ensure the completeness and accuracy of his or her proposal. Corrections will not be made by the Government.

INFORMATION SHALL BE PROVIDED IN VOLUME I.

The cover shall indicate the following:

The introduction shall briefly state the purpose and content of the proposal.

3.7.4 Technical

Demonstrate understanding/approach to meet requirements of Performance Work Statement.

The Offeror shall demonstrate relevant corporate experience related to the evaluation criteria. Recent Relevant experience is experience (within the last 3 years) that is of the same or similar scope and complexity to the work described in the Performance Work Statement, and is to demonstrate its corporate experience, the Offeror shall identify up to three (3) of its most relevant contracts or efforts within the past three (3) years, and provide any other information the Offeror considers relevant to the requirements of the solicitation. Offerors shall provide a detailed explanation demonstrating the relevance of the contracts or efforts to the requirements of the solicitation.

The project description shall clearly describe the projects. The Government will not assume any project characteristics that are not specifically identified and described. The offeror may describe how the project contained the elements described above meets the requirements of this factor. The submission must contain sufficient information for the Government to determine whether the project meets the requirements of 3.7.4.

To the extent that the Offeror intends to subcontract significant portions of the effort, for each subcontractor the Offeror shall identify up to three (3) of the most relevant contracts or efforts within the past three (3) years and provide any other information the Offeror considers relevant to the requirements of the solicitation. In evaluating subcontractor experience, the relevance of subcontractor experience will be determined based on the scope, complexity, and magnitude of the aspects of the work in the solicitation for which the subcontractor is proposed to perform. Therefore, the proposal shall detail clearly the aspects of the work in the solicitation that each subcontractor is intended to perform. The Offeror shall also provide information as to where the subcontractor fits into their organizational chart.

3.8 Volume II - Past Performance Proposal

The Offeror shall demonstrate relevant past performance or affirmatively state that it possesses no relevant past performance. Relevant past performance is performance under contracts or efforts within the past three (3) years that is of the same or similar scope, complexity, and magnitude to that which is described in the solicitation (as explained under the Experience subsection).

If the Offeror has limited experience within the past three (3) years, but does have relevant experience beyond three (3) years in the past, a full description of this past experience must be given along with a narrative describing why this past experience is still relevant and what steps have been taken over the intervening time span to retain the necessary technical expertise and capability to fulfill the requirements of the Performance Work Statement.

Offerors are reminded that both independent data and data provided by Offerors in their proposals may be used by the Government to evaluate Offeror past performance. Since the Government may not necessarily interview all the sources provided by the Offerors; it is incumbent upon the Offeror to explain the relevance of the data provided. The Government does not assume the duty to search for data to cure problems it finds in the proposal. The burden of providing thorough and complete Past Performance information remains with the Offerors. Proposals that do not contain the information requested risk rejection or less than acceptable performance rating by the Government.

Past Performance Questionnaire - The Past Performance Questionnaire (PPQ) included in the solicitation is provided for the offeror or its team members to submit to the client for each project the offeror includes in its proposal for Volume II, Past Performance. Ensure correct phone numbers and email addresses are provided for the client point of contact. Completed Past Performance Questionnaires should be submitted with your proposal. If the offeror is unable to obtain a completed PPQ from the client for a project(s) before proposal closing date, the offeror should complete and submit with the proposal the first page of the PPQ (Attachment A), which will provide contract and client information for the respective project(s). Offerors should follow-up with clients/references to ensure timely submittal of questionnaires.

If the client requests, questionnaires may be submitted directly to the Government's point of contact, Amanda Andrews and Sonia Boyd via email at Amanda.Andrews@usace.army.mil and Sonia.J.

Boyd@usace.army.mil prior to proposal closing date. Offeror shall not incorporate by reference into their proposal PPQs previously submitted for other RFPs. However, this does not preclude the Government from utilizing previously submitted PPQ information in the past performance evaluation.

Also include performance recognition documents received within the last two (2) years, such as awards, award fee determination, customer letters of commendation, and any other forms of performance recognition.

In addition to the above, the Government may review any other sources of information for evaluating past performance. Other sources may include, but are not limited to, past performance information retrieved through the Contractor Performance Assessment Reporting System (CPARS), using all CAGE/UEI numbers of team members (subcontractor, partnership, joint venture, teaming arrangement, or parent company/subsidiary/affiliate) identified in the offeror's proposal, inquiries of owner representative(s), Federal Awardee Performance and Integrity Information System (FAPIIS), Electronic Subcontract Reporting System (eSRS), and any other known sources not provided by the offeror.

While the Government may elect to consider data from other sources, the burden of providing detailed, current, accurate and complete past performance information rests with the Offeror.

New Corporate Entities -- New corporate entities may submit data on prior relevant and recent contracts as explained under the Experience subsection (within the last three (3) calendar years) involving its officers and employees. However, in addition to the other requirements in this section, the Offeror shall discuss in detail the role performed by such persons in the prior contracts cited. Past performance information on work for state and local governments, private sector clients, and subcontractors that are similar to the Government requirement will be evaluated equally with similar federal contracts. Offerors may submit information on key personnel, major subcontractors, and work performed as part of a team or joint venture and other previous reincarnation of its current organization.
