Answer: See answer to question 21.

32. Can a subcontractor holding the relevant manufacturer applicator certification and past performance satisfy the technical/experience requirements on behalf of a prime contractor that does not independently hold that certification? Is there a required minimum percentage of work that must be self-performed by the prime versus subcontracted?

Answer: The Government will permit offerors to propose qualified subcontractors to perform portions of the required work. A subcontractor's manufacturer applicator certification and relevant experience may be considered as evidence of the offeror's ability to perform the requirement, provided that the subcontractor is identified in the proposal and is committed to performing the applicable work. However, where the solicitation specifically requires the prime contractor itself to possess a certification, that requirement must be satisfied by the prime contractor and may not be satisfied solely through a subcontractor.

The solicitation does not establish a separate minimum percentage of the work that must be self-performed by the prime contractor, unless otherwise stated in the solicitation or required by applicable Federal Acquisition Regulation provisions. The prime contractor remains responsible for the overall performance of the contract and for the performance of its subcontractors.

33. Is a U.S.-domiciled prime contractor with an Egypt-based subcontractor performing the on-the-ground work an eligible teaming structure for this acquisition?

Answer: Yes, provided that the proposed teaming arrangement complies with all applicable solicitation requirements and the prime contractor remains responsible for performance of the contract.

34. For the clay tile roof sections, should offerors price Alternate Option 1 (historic/modern hybrid) or Alternate Option 2 (fully historic) as the base bid, or should both be priced separately for evaluation?

Answer: Both shall be priced separately for evaluation.

Answer: There are no other limitations other than those provided.

50. Phase 1 Preliminary Project Understanding Statement Reference: Section L, Volume 1, Phase 1 Mandatory Minimum Requirement No. 5; Volume 2, Tab A, Performance Schedule and Narrative.

Volume 1 requires a preliminary project-understanding statement, while Volume 2 requires a detailed performance schedule and narrative.

Please confirm whether the Phase 1 statement must be a separate Volume 1 submission or may cross-reference the detailed Volume 2 narrative.

Answer: These are separate submission requirements and serve different purposes. The Phase 1 Preliminary Project Understanding Statement is a Phase 1 Mandatory Minimum Requirement and shall be submitted in Volume 1 as specified in the solicitation. The Performance Schedule and Narrative in Volume 2 is a separate submission addressing the quoter's proposed schedule and execution approach. Accordingly, the Phase 1 Preliminary Project Understanding Statement may not be satisfied solely by cross-reference to the Volume 2 Performance Schedule and Narrative. The quoter shall provide the required Phase 1 statement in Volume 1; however, the quoter may avoid unnecessary duplication by appropriately cross-referencing information contained in Volume 2, provided that the Phase 1 submission itself clearly demonstrates the required project understanding.

51. Authorization to Perform in Egypt. Reference: Section L, Volume 1, Phase 1 Mandatory Minimum Requirement No. 3; DOSAR 652.242-73, Authorization and Performance. The solicitation permits a quoter to provide a plan for obtaining authorization to operate in Egypt but does not identify the specific authorization required. Please confirm:

a. if Egyptian registration, license, permit, or other authorization is required of the Prime Contractor.

b. whether the Prime must hold the authorization directly or may satisfy the requirement through a properly licensed Egyptian subcontractor or partner.

c. when the authorization must be fully obtained.

Answer: If work is performed by an Egyptian subcontractor, the quoter shall identify the proposed subcontractor and provide evidence of the subcontractor's applicable authorization, licenses, and permits as per local laws and regulations. The prime contractor remains responsible for ensuring that the contract is performed in accordance with DOSAR 652.242-73 and applicable Egyptian laws and regulations.

If the quoter itself will perform work in Egypt for which an authorization, license, or permit is required, the quoter must obtain and maintain the applicable authorization, license, or permit. If the quoter has not obtained such authorization, the quoter shall provide all documents stated in attachment 1, page 72, sub-part 3. Full authorization must be provided within 30 days of award.

52. Key Personnel - Prior Relationship with the Contractor:

Reference: Section H.14.1, Key Personnel; Section L, Volume 2, Tab B, Key Personnel:

Please:

a. Confirm whether the one-year prior working relationship is a mandatory qualification at quotation submission.

b. Confirm whether personnel proposed under a Letter of Intent who have not previously worked with the quoter for one year may satisfy this requirement.

Answer:

a. Yes. In accordance with Section H.14.1, at least two of the three proposed Key Personnel must have worked with the quoter for more than one year on similar projects. This is a mandatory requirement and must be demonstrated at the time of quotation submission.

b. Personnel proposed pursuant to a Letter of Intent may be considered for the Key Personnel requirement; however, the Letter of Intent does not waive or replace the one-year prior working relationship requirement in Section H.14.1. Accordingly, at least two of the three proposed Key Personnel must satisfy the one-year prior working relationship requirement, regardless of whether they are current employees or proposed under a Letter of Intent. A third Key Person may be proposed under a Letter of Intent without having previously worked with the quoter for one year, provided that all other applicable Key Personnel requirements are satisfied.
