Q&A Solicitation 040ADV-25-R-0016 GPO – NARA 4th Floor Renovation

Q.1 Would it be possible to include site photos in the RFI responses?

RFI responses will be written.

Q.2 Can the Government confirm if the following document types are or would be count(ed) against the 120-page limit associated with this solicitation: cover, title page, table of contents, first page?

Cover, title, table of contents and first pages are NOT counted against the 120-page limit.

Q.3 For “graphic presentations, including tables” may offerors use 11x17 pages? If so, would each such page count as one or two pages against the 120-page limit associated with this solicitation?

Offerors may use 11x17 sheets for graphic presentations. Each 11x-17 will be counted as a single page.

Q.4 Volume 3: “The Offeror shall submit a comprehensive Quality Control/Quality

Assurance (QC/QA) Management Plan.” Is the Government looking for a summary or a draft of a complete, post-award-type submittal? If the latter, these plans are often 50 pages or more; can the Government confirm if this Plan is excluded from the 120-page limit?

A full, post-award level plan is not required. Please adhere to the solicitation instructions.

Q.5 Volume 3: “The Offeror shall submit a comprehensive Safety Plan.” Is the

Government looking for a summary or a draft of a complete, post-award-type submittal? If the latter, these plans are often 50 pages or more; can the Government confirm if this Plan is excluded from the 120-page limit?

See response to Q.4.

Q.6 Volume 3: “An Accident Prevention Plan (APP) is required for this contract and must be job site specific.” Is the Government looking for a summary or a draft of a complete, post-award-type submittal? If the latter, these plans are often 50 pages or more; can the Government confirm if this Plan is excluded from the 120-page limit?

See response to Q.4

Q.7 Volume 5: “The offeror’s proposal submission must include a minimum of three completed past performance questionnaires, but no more than five completed questionnaires, to enable proper evaluation. An offeror may submit other forms of past performance records as supplemental information, including CPARS. The supplemental information, however, may not be submitted in lieu of the PPQ form.”

Would the Government reconsider and allow offerors to submit CPARS in lieu of new PPQ forms submitted directly to the Government? Such existing federal-form evaluations are designed for this purpose and would evaluate the relevant categories.

Evaluators/references are often reluctant to complete new evaluations when existing evaluations are already available and have already been completed for this type of situation and purpose. In addition, over a multi-year look-back, references are very often no longer available. These are circumstances that are beyond an offeror’s control and that can impact proposal scores unnecessarily and an offeror’s ability to present its most recent and relevant work. Allowing such existing evaluations – in lieu of new PPQ forms – helps offerors provide the best experience information and most thorough proposals possible for the Government’s consideration. And because they would be evaluations on official, federal forms, they would still allow the Government to assess offeror past performance effectively.

Offerors must comply with all solicitation instructions. CPARS may be submitted as supplemental information; however, supplemental information cannot be used as a substitute for the required questionnaires.

Q.8 Volumes 1 and 6: Can the Government confirm if offerors should count the information applicable to these two Volumes against the 120-page limit associated with this solicitation?

Except for tables of content, the cover page, and the first page, all sheets will count against the 120-page limit.

Q.45 Sheet A702 - Detail E6 notes that there is an add alternate for brick infill at Central shafts 1-10. This work is to include new doors. This alternate work is not noted in the RFP/Price schedule, and these doors are not shown on the door schedule. Please confirm that an alternate for the work shown on Sheet A702 - Detail E6 is to be

Base Bid vs. Alternate: While the architectural detail notes this as an "Add Alternate," the Government has determined that this work is not required for the functional completion of the NARA 4th Floor Renovation currently.

Q.46 Provide a cut section or detail for new drywall element at E5 & D5/A702

The drywall must extend from the finished floor through the suspended ceiling grid and terminate at the underside of the structural deck above.

Q.47 Wall type SOZ shown on A801 appears to indicate in-wall insulation but does not call it out. Please confirm insulation will not be used on wall type SOZ.

Wall Type SOZ is a specialized "Archival Partition" designed for acoustic separation and thermal stability:

(1) Insulation Requirement: 3-1/2" thick Mineral Wool Sound Attenuation Fire Batts

(SAFB).

(2) Framing: 3-5/8" 20-gauge metal studs at 16" O.C.

(3) Facing: 5/8" Type X Gypsum Board on both sides, extending slab-to-slab as defined in Q.46.

Q.48 Notes AD14 and AD15 on AD102 as well as notes AF23 and AF24 on A102 call for patching in Existing Mechanical Room A421 walls. Please advise on wall types being patched.

Based on the Existing Conditions Survey and the Architectural Demolition (AD) series drawings, the walls within and surrounding Mechanical Room A421 consist of two primary construction types. The patching required by the notes mentioned shall match these existing assemblies:

(1) Concrete Masonry Unit (CMU) Walls: Where old piping, conduits, or ductwork are removed (per notes AD14/AD15), the contractor must infill the openings with matching CMU blocks.

(2) Finish: The patch must be finished with a sand-finish mortar joint to match existing.

In areas visible to the public or office staff, a skim coat of plaster or joint compound may be required to achieve a flush, paintable surface (per notes AF23/AF24).

(3) Fire Rating: Because Room A421 is a mechanical shaft/space, these walls are part of a 2-hour fire-rated assembly. All patches must be fully grouted, and any remaining gaps must be sealed with UL-listed fire-stopping mortar or intumescent sealant.

Q.49 B4/A703 shows the lightweight concrete topping abutting the face of the furring wall that goes around the perimeter of the floor. Partition detail SOZ on A801, however, shows the concrete topping passing under the furring wall and abutting a piece of blocking. Please advise if the concrete topping is to abutt the face of the furring wall or pass under it.

The lightweight topping is non-structural. Mounting the furring wall directly to the structural slab provides a more stable substrate for the wall framing than mounting it on top of the topping material.

Q.50 Price schedule "J.6+-+Cost-Price+Proposal+-+Excel+NARA" includes 6 CLINs while the RFP-Section B includes 1 CLIN. Is this project to be priced as a single lump sum or broken into the 6 CLINs in the Excel Price schedule?

The project must be priced using the six-CLIN breakdown as provided in Attachment J.6 (Excel Price Schedule). While Section B of the RFP may show a single aggregate CLIN for administrative summary purposes, the detailed cost breakdown in the Excel document is mandatory for a responsive bid.

Q.51 The bid documents are broken into Phase 1 - Architectural and HVAC upgrades minus the dehumidifier work and Phase 2 - Installation of high bay storage systems and dehumidifiers. The CLINs in the Price Schedule do not appear to align with the phasing in the Bid documents. Is this project to be priced as a single lump sum or priced

Phase 1 (Abatement, Demo, HVAC Upgrades): This work should be distributed across CLIN 0001 (Abatement/Demo) and CLIN 0002 (Infrastructure/MEP).

Phase 2 (High-Density Storage & Dehumidifiers): The storage systems should be captured under CLIN 0004, while the dehumidification units and their specialized integration fall under the remainder of CLIN 0002.
