(End of Summary of Changes)

Section 00 22 11 W911KB-19-R-0020

Section 00 22 11 Page 4

5.1.2 Provide a one-page consolidated list of the Specialized Experience projects to include a matrix that identifies the projects and the firms that worked on each one (teaming). Identify if the offeror was the prime on the contract or a subcontractor. Include the completion date and dollar amount executed on the project by the firm establishing the specialized experience.

5.1.3 Provide a supplemental narrative, not to exceed two (2) pages, to address any of the following that are applicable. The information shall be limited to projects that are well underway (at least 50% completed) or that have been completed and turned over no longer than six (6) years preceding the date of this solicitation.

a. Offerors who submit experience information of a parent, sister or other affiliated company shall describe what involvement such company will have on the instant acquisition and demonstrate a firm commitment that the affiliated firm will participate meaningfully in the performance of the contract. The narrative shall clearly and specifically indicate how the resources of the parent, sister, predecessor or other affiliated company – its workforce, management, facilities, or other resources – will be provided or relied upon for contract performance. The Government may discount experience of a parent, sister, predecessor or other affiliated company unless the prime contractor clearly provides, in its proposal, evidence of a binding teaming agreement or other contractual agreement which creates legal responsibility on the part of the parent, sister, predecessor or other affiliated company. If there is no contractual arrangement between the prime contractor and the parent, sister, predecessor or other affiliated company, provide a

Meaningful Relationship Commitment Letter including the following:

1. A statement of commitment as to the performance and utilization of the identified entity’s resources on this project.

2. Signatures of both the Offeror and Meaningful Relationship Entity.

b. AM#02… Provide a list of subcontractors and describe any previous teaming experience between the prime contractor and subcontractors identified under Tab C. Provide a matrix that identifies specific projects and teaming. …AM#02

c. If submitting projects performed under a prior business arrangement (joint venture, for example) for Factor

1, Specialized Experience, address why that experience is relevant to the experience of the firm submitting the offer.

Clearly identify the role and responsibilities of each joint venture partner.

5.2 Evaluation Criteria:

5.2.1 The Government will evaluate the extent of recent, relevant experience of the prime contractor as relevant to their role proposed on this project. Experience on the similar projects identified on the project experience sheets (Attachment

2) will receive more consideration than experience provided in the supplemental narrative. The Government may place greater importance on projects performed as a prime contractor than as a subcontractor, depending upon overall role and relevancy considerations. Federal Government project experience will not be rated inherently more important than non-

Federal Government project experience. In assessing relevancy of Specialized Experience, the relevancy ratings included at the end of this section will be utilized.

5.2.2 The Offeror must submit the requested information to demonstrate a record of recent, related experience for construction of the facility type, which may include similar state or local government or private counterparts. Recent experience includes projects well underway (at least 50% completed) or those completed and turned over within six (6) years of the proposal issue date for this RFP for construction experience. Joint Venture partners shall each demonstrate

Section 00 22 11 W911KB-19-R-0020

Section 00 22 11 Page 10 field overhead costs through the proposed contract duration are inclusive in the offered price for the contract.

9.3.2 If deemed necessary, the supplemental price breakdown information will be used to assist the Government in performing the price evaluations described above.

10.0 VOLUME 2, TAB B - REQUIRED PRE-AWARD INFORMATION

10.1 Submission Requirements:
