REVISED 6/25/2020

SECTION 00 11 00 - Page 2

4.0 SPECIFIC PROPOSAL SUBMISSION INSTRUCTIONS

4.1 There are three separate volumes required in response to this solicitation. Volume I includes four

(4) non-priced evaluation factors that will be evaluated. Volume II includes administrative requirements and proposed pricing. Volume III includes Subcontracting Plan (Individual Contract

Plan). In general, the non-priced factors are considered significantly more important than price in relative importance.

EVALUATION FACTORS AND ORDER OF RELATIVE IMPORTANCE

4.2 VOLUME I - TAB A, FACTOR 1 – PAST PERFORMANCE INFORMATION OF THE PRIME

CONTRACTOR

The Past Performance of the Prime Contractor (Offeror) consists of RELEVANT COMPANY EFFORT and QUALITY OF PAST PERFORMANCE. The Government will review recent, relevant company efforts and quality information provided by the owners of those efforts to assess the Offeror’s past experience and probability of successfully performing the work described in this solicitation. A recent, relevant project is a construction project:

• That was performed under a contract or task order, as those terms are defined in FAR 2.101, for

Federal projects, or similar contractual agreements for State or Local Governments, or the commercial or private sector. Multiple projects under a single contract or task order are considered to be one project. However, do not combine multiple projects under separate contracts or task orders to create a single project.

• That is “recent”; one that has been completed within ten (10) years of the solicitation issue date, or one where the construction is at least 75% complete (measured by performance period days) as of the solicitation issue date. Offerors are responsible for providing start and completion dates for each completed project, or the start and scheduled completion dates for projects currently under construction.

• That is “relevant”; one that is similar in scope (type, size, complexity and dollar value) to the project described in this solicitation. For a project to be assessed on any degree of “relevancy”, it must reflect the performance of construction type work similar to the project required by this solicitation.

4.2.2 QUALITY OF PAST PERFORMANCE

4.2.2.1 The Offeror shall submit evidence of the quality of their past performance for each of the provided projects. For Federal Government projects, the Offeror shall provide a completed contractor performance evaluation, whether interim or final, found in the Contractor

Performance Assessment Reporting System (www.cpars.gov/). If a proper evaluation does not exist in CPARS, because it has not been completed or the project is a non-Federal Government project, the Offeror shall provide a completed Past Performance Questionnaire (PPQ) (See

Attachment 3). If, at time of evaluation, a final contractor performance evaluation exists in

CPARS, and yet the Offeror submits a PPQ, only the evaluation in CPARS will be considered.

4.2.2.2 Past performance surveys/assessment/evaluation forms other than CPARS or PPQs are unacceptable and will not be considered or evaluated.

4.2.2.3 Completed PPQs that were submitted in response to previous solicitations may be used in this source selection. However, Offerors shall not incorporate such PPQs by reference and thus must resubmit the PPQ with their proposal. This does not, however, preclude the Government from utilizing previously submitted PPQ information in the Past Performance evaluation.

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

4.2.2.4 If an Offeror has been required to take corrective action for any substandard performance or experienced other performance problems such as cost overruns, extended performance periods, numerous warranty calls, etc., the Offeror should explain the circumstances and the corrective actions taken.

4.2.2.5 If an Offeror’s client/customer will only provide completed PPQs directly to the U.S. Army

Corps of Engineers, Mobile District, Offerors must ensure the client/customer submits the

PPQ by the proposal due date using the following electronic mailing address: CTHYDRO-

PROPOSALS@usace.army.mil. The solicitation number shall be included on the PPQ form.

PPQs received after the proposal due date will be considered untimely and will not be considered during the evaluation.

4.2.3 JOINT VENTURE SUBMISSION REQUIREMENTS

4.2.3.1 Like other Offerors, a JV Offeror shall provide no more than eight (8) examples of recent, relevant projects performed by the JV that reflect the JV’s ability to perform the work required in this solicitation.

4.2.3.2 If the JV Offeror does not have projects performed as a JV, the Offeror may supplement those projects it performed as a JV with recent, relevant projects performed by the members of the

JV in their individual capacities. In such instance, the total number of projects submitted by the JV shall be no more than eight (8).

4.2.3.3 If the JV Offeror has not previously performed as a JV, each member of the JV may submit recent, relevant projects performed in their individual capacities. The total number of projects submitted by the JV shall be no more than eight (8).

4.2.3.4 All Business Entities: To satisfy Paragraph 4.2.1 and 4.2.2 only information pertaining to the corporate entity listed on the SF 1442 will be considered in the evaluation. Information related

SECTION 00 11 00 - Page 8 to a parent company, affiliates, divisions, subsidiaries, other related entities, subcontractors, or the individual experience of key personnel will not be considered.

4.2.4 VERIFICATION

The Government reserves the right to verify the information on projects submitted for evaluation, and to review CPARS, or other Government project appraisal systems, for information on other projects performed by the Offeror whether submitted as part of a proposal or not. The Government also reserves the right to contact project clients/customer, or other references. For any adverse performance information found for which the Offeror has not had an opportunity to address, the

Offeror will be afforded an opportunity to explain.
