Questions and Answers

3. Factor 4; Key Personnel; P. 63 of 64: The Key Personnel section of Factor 4 lists out seven (7) different Key Personnel roles, but it does not go into detail about what specifically the offeror/bidder should provide. Please advise what information the offeror/bidder should provide under this section.

a. The contractor shall decide the pertinent details to provide for each key personnel.

4. Price Proposal; P. 63 of 64: The solicitation does not specifically mention what items/information should be included in the Price Proposal. Please advise if the following contents are acceptable. If not acceptable, please advise what all should be included in the price proposal. Contents: SF 1442; Amendments; Section B - Supplies or Services and Prices/Costs; Cost Breakdown Example; Bid Bond; Reps & Certs (from the solicitation - Section K); CPARS Requirements form (L.6 of the solicitation).

a. Refer to the solicitation for required items to include in the price proposal.

5. Exhibit A Breakdown Example: Please advise if the CDC will be issuing a clean version of this form for the offeror/bidder to use, or if the offeror/bidder is to use the example form and replace the example data with project specific data.

a. The form provided can be edited as needed.

6. Section K – Representations, Certifications, and Other Statements of Offerors: K.7

HHSAR 352.239-73 Electronic Information and Technology Accessibility Notice (Dec 2015): “…offerors must submit an HHS Section 508 Product Assessment Template, in accordance with its completion instructions.” As this project is for construction services, and not information/technology services, please advise if the offerors of this particular project are required to complete and submit this form (HHS Section 508 Product Assessment Template) with their bids. If so, please confirm if the “Voluntary Product Accessibility Template® (VPAT®) Revised Section 508 Edition Version 2.4” is the correct form, which must be completed. If not, would the CDC be willing to post the correct form for offerors to complete?

a. HHSAR 352.239-73 is a mandatory clause to include in all contracts. The relevant portion of that clause reads, “In order to facilitate the Government’s determination whether proposed EIT supplies meet applicable Section 508 accessibility standards, offerors must submit an HHS Section 508 Product Assessment Template”. Here, the CDC is not purchasing Electronic and Information Technology (EIT) services or supplies so there is no need to determine accessibility therefore, no need to submit this form.

7. While section 01 54 60 Health and Safety does not call out a dedicated On-Site Safety Health Officer (SSHO) – can the contractor assume that the On-Site Project Superintendent can fulfill those duties?

a. It is at the contractor’s discretion to provide the appropriate qualified person(s) responsible for the tasks outlined in this specification.

8. While section 01 40 00 Quality Requirements does not call out a dedicated Site Quality

Control Manager (QCM) – can the contractor assume that the On-Site Project Superintendent can fulfill those duties?

Would it be possible for the government to provide architectural drawings showing the various connecting corridors from building 15 to the shared loading dock?

a. See attached drawings.

10. Amendment # 1 – Justification and Approval for Hood-Paterson & Dewar (HPD). While we understand the governments sole-sourced justification for HPD to handle all studies as outlined in section 26 05 73, question # 10 of the JA states “ This work must be coordinated with the balance of construction work for CDC project P20151192 Replace Air Handling Units – GARO0015. It is best to award this as a requirement for the construction contract so that the General Contractor can coordinate this requirement and integrate it into the construction schedule”. Is the cost for HPD to be covered by the GC or the government? If cost is by the GC can the government provide the contact for

HPD?

a. Costs shall be included by the GC. Contact Susan Pandy (770) 453 – 1446.
