About this file
This is a Questions and Answers (Q&A) document for Air Force solicitation FA875126Q0013, a Request for Quotation (RFQ) for the renovation of Suite H8 in Building 3 at the Air Force Research Laboratory. The document addresses clarifications submitted by potential offerors during the pre-bid phase and provides government responses to technical and procedural inquiries. Key technical clarifications include confirmation that Victaulic mechanical pipe joining is approved for chilled water and heating water systems; all piping within, above, or below the cleanroom envelope (rooms H8-K, H8-L, and H8-M) must be 316 stainless steel, with the exception of chlorine gas lines which require carbon or alloy steel per Chlorine Institute specifications; ductwork serving the cleanroom must be welded 316 stainless steel while remaining ductwork can be galvanized sheet metal constructed to SMACNA standards for 2.0 inwg static pressure; unit pricing per foot for stainless steel and carbon/alloy steel final connections is required; and BILCO Type T access doors should be provided in the custom size of 2'-2" x 5'-0" as indicated. The government clarified that missing drawings (S-4, S-7, S-11), specification section 22 00 00 (Plumbing), and Job Drawing JD-001 have been provided as attachments. The RFI period closed on 25 September 2026 at 1600 EST, and Amendment 0001 extended the solicitation response date to 23 October 2026. The acquisition is set-aside for small business concerns and incorporates FAR provisions by reference. Several questions remain unanswered, including responsibility for fiber cable management, access card reader installation, phone and intercom maintenance contracts, and the acceptability of stainless steel EMT conduit in cleanroom areas versus rigid conduit.

Sheet1
| Question | Government Response |
| It appears that drawings S-4, S-7 and S-11 are missing. Can you those be provided? | See attachments S-4, S-7, S-11 |
| Are Victaulic Fittings acceptable for the chilled water and heating water in the H8 Suite Area? | Mechanical pipe joining (Victaulic) is listed as an approved pipe joining method in the specifications, therefore, it is approved for the HWS/R and CHWS/R |
| Does the piping in the Plenum above the Clean areas required to be 316 Stainless Steel? | Piping/Utilities (including all supports, hangers, etc.) touching the cleanroom envelope (within, above or below H8-K, H8-L, & H8-M) need to be Stainless Steel |
| Does the 1/2" 'Various Gas' lines required to be 316 Stainless Steel in the trench from Tank Storage H8-E Dirty Room H8-K? | Yes, Gas storage manifold detail states: “gas piping, except CL2, to be brazed stainless steel”. That means all of the various gas piping needs to be SS. General note off to the right side of sheet P-1 also includes DCW, DHW, DHWR, SAN & VENT within the cleanroom envelope |
| Are we required to provide a unit price per foot for final connections per Note on drawing P-1? | Yes, a unit price for ½” SS & Carbon/Alloy Steel is required to make final field routing as field directed by Owner |
| The entire CSI section 22 "Plumbing" is missing from the contract documents, could you kindly provide that specification section? | See attachment Spec section 22 00 00 |
| Drawing P-1 shows a note for use of 316 stainless steel for all piping in the clean room environment. Is this limited to the Class 100 clean room, or is the dirty room (Class 1000) included as well? | Exposed to the cleanroom environment” means anything in, under or above (based on the airside mechanical scheme) rooms H8-K, H8-L, and H8-M (all three cleanroom areas). Also noted - Chlorine gas is not compatible with 316 SS and will need a carbon or alloy steel pipe rated for service Class 1 Dry Gas Chlorine. See Chlorine Institutes Pamphlet 6, “Piping Systems for Dry Chlorine”. This is stated on the Gas Storage Manifold Detail and is the exception that was noted by the general notes off to the right side of Sheet P-1. |
| In the Auxiliary Equipment Room H8-H, the domestic water line is shown coming into an apparatus labeled "1." I cannot find what that item references on the schedule | Text wouldn’t fit in the spot of “1” on the floor plan and is shown just up and to the right, same sheet. Note reads: “Fleck / 2815 Backwashing Sediment Filter (40 gpm)” |
| The plans call for two 2’2”w x 5’0”l Bilco hatches. |
The sizes for this type of hatch are limited to the following for a single leaf door:
2’x2’ 2’6” x2’6” 3’0” x 2’6” 3’0” x 3’0” 3’6” x 3’6”
In a double leaf door the sizes are:
4’x4’ 4’x6’ 5’x5’
| Can you let us know if the size of the door can change - or the other option would be to change the type of door to just a diamond plate cover instead of receiving VCT flooring? | Hatches indicated in the plans in Passage H8-C – the intent is a BILCO Type T access door – to accept floor finish. Plans indicate 2’-2” x 60”. This is correct – provide custom size indicated. | |
| Are there any restrictions on deliveries into the site? | All deliveries must be searched by entering the right lane at the entrance gate. Suggest avoiding the ‘rush hour’ of 0600 – 0800. Standard site access ID requirements are in place as detailed in the solicitation. | |
| What are your thoughts on the columns to the penthouse? | Need to penetrate the roof with the column. There is a lot of sensitivity to vibration which is the reason for the penthouse. Everything coming into the facility is taking vibration into account. The instruments that will be used in the facility are very sensitive to vibration. | |
| What is the RFI period? | RFI’s will be accepted until 1600 on 25 September 2026 | |
| Can the door by the boilers be used to remove debris and concrete? | Likely not as it is a temporary door and may not be there when this project commences. An alternate route will have to be used | |
| Is the slab floor coming out and what is the thickness? | Yes, a large portion of the slab will need to be removed. Approximately 8” thick | |
| Can propane minis be used for debris removal? | Yes | |
| Has the FRP color and type been selected already? | Unknown at this time but not applicable | |
| Can you provide the cost range of this project? | No, we don’t provide that information | |
| When does the ‘clock start’ on this project? | We will issue the award and hold a pre-con meeting. Then a notice to proceed will be issued with likely a 10-day window | |
| Can long lead time items be done ahead of the ‘clock start’ | Yes | |
| Will the roofing and boiler projects be on-going during this project? | The roofing should be complete. The boiler will be on-going | |
| Are pictures allowed to be taken? | No, but we may be able to provide specific pictures upon request (see excel sheets) | |
| Drawing S-2 indicates a sizable amount of hatched area where we are reinforcing the existing roof with 2x12’s @ 16” O.C. (note 1, ~ 1200 SF) and reinforcing the existing roof with 11 ¼” LVL @ 16” O.C. (note 2, ~ 2300 SF). Other than these two notes, is there additional information or details regarding the reinforcing? Please provide more information | Refer to Job Drawing JD-001 | |
| Spec section 2.8.1.a references Appendix D of Section 23 05 93 for duct system static pressure requirements. Appendix D seems to be missing and the spec section stops at Appendix C. Please provide static pressures requirements for duct fabrication. | AHU’s and EF’s are all categorized as low pressure (under 2.0 inwg and 2,000 fpm), ductwork should be constructed to current SMACNA Standards for 2.0 inwg static pressure. Please disregard the reference to Appendix D. | |
| It is noted that all duct associate with the cleanroom space is welded SS 316 per notes 1 on the central station air handling schedule. Power ventilator schedule has a note 2 in the title, but it is not shown in each line item for the individual fans. Can it be assumed that all duct with the power ventilators is welded 316 SS? What material are the remaining ductwork systems? | This will be clarified via Addendum. Ductwork serving AHU-H8-MEL and EF-H8-MEL can be galvanized sheet metal constructed to current SMACNA Standards for 2.0 inwg static pressure. | |
| Is it the intent that the owner will provide all equipment shown on drawing G-2? | All equipment indicated on Dwg G-2 is by the Government - except plumbing fixtures (ie: sink and eye wash) | |
| Is there a preferred cleanroom consultant contractor within the AFRL? | We don’t have a preferred cleanroom consultant | |
| Unanswered Questions |
Is the fiber cable in the corner to be dealt with on this project? It’s not shown in the specs
Who is responsible for installation of access card readers on the doors?
Is there a contract that does the phone and intercom maintenance?
In existing LAB H8-A East Wall there is cable tray & conduit going down to a 24” junction box with Communication cables( Fiber/Copper). None of the Demo drawings show removals, does this need to be removed/relocated?
Can device boxes and conduit be concealed in Clean/Dirty/Gowning rooms walls or does it need to be surface mounted?
Can Stainless steel EMT be used for Clean/Dirty/Gowning rooms, in place of stainless steel Rigid conduit?
