CONTINUATION SHEET

1. QUESTION: Section 23 07 00 Part 3.3 “Duct Insulation Systems Installation” does not require for exhaust ducts to be insulated. However, the exhaust ductwork serving the E1 grilles (in the closets and bathrooms in the sleeping rooms) is being routed to a DOAS unit with energy recovery. Does the exhaust ductwork from the sleeping rooms to the DOAS need to be insulated, and if so, what thickness is required?

ANSWER: Spec section 23 07 00 was updated as part of Amendment 01, 06/30/26

2. QUESTION: Note 6 on P-001 indicates that all vents to have vandal proof hoods. Detail C6 on drawing P-501 indicates for the vent to be installed without a vandal proof hood. Are we to install the vents per detail C6 on drawing P-501?

ANSWER: No. Vandal proof hood vents are not required for this project.

3. QUESTION: There is no specification indicating the type of material to be used for the gas piping. Please provide specification.

ANSWER: Spec section 23 11 20 will be provided.

4. QUESTION: Detail C1 on drawing M-504 Pre-Heat Coil Piping does not show a strainer on the main supply line serving the DOAS Units, nor does it show a check valve on the main supply line to keep the recirculation pump from circulating on the supply side and not through the coil.

See attached drawing and red line valves for possible installation to prevent this issue and protect the coil. Will recommended strainer and check valves be required?

ANSWER: Sheet with updated details will be provided.

5. QUESTION: Adhesive labels with arrows in the specified colors have been sufficient for pipe designation at Camp Lejeune. Will adhesive labels be allowed in lieu of snap on or wrap around labels shown on detail D4 on drawing P-504 and detail A4 on drawing M-504?

ANSWER: DOR takes no exception to the use of adhesive labels in lieu of snap on/wrap around labels.

6. QUESTION: Section 33 61 14 Exterior Buried Preinsulated Water Piping, paragraph 1.2- System Description says “Piping system includes hot domestic water piping, recirculating hot domestic water piping, chilled water piping, and related work.” There is no mention of heating hot water piping. What are the requirements for the exterior buried preinsulated heated hot water piping?

N40085-26-R-9044 Amendment 0004

ANSWER: 33 61 14 applies to hot water piping. Description should read, “Piping system includes hot domestic water piping, recirculating hot domestic water piping, chilled water piping, hot water piping and related work.”

7. QUESTION: Note 5 on Air Distribution Schedule on drawing M-601 calls for a minimum-security face plate with tamperproof screws. Is the intent for this to have a minimum-security type grille, or a standard grilled with a security cover installed over it?

ANSWER: Note 5 states: "PROVIDE GRILLE WITH FACTORY PROVIDED/INSTALLED

OPPOSED BLADE DAMPER."

8. QUESTION: Plumbing Equipment Schedule on P-601 show a thermostatic mixing valve tagged TMV-2 to be located on the Laundry Restroom. We cannot find this mixing valve anywhere on the drawings except the schedule. Where specifically do this mixing valve located?

ANSWER: This mixing valve is not required for this project.

9. QUESTION: Shower drains are listed in specification section 22 00 00 paragraph 2.6.1 Floor & Shower Drains. These drains are listed to have a “galvanized body, integral seepage pan, and adjustable perforated or slotted chromium-plated bronze, nickel-bronze, or nickel-brass strainer, consisting of grate and threaded collar.” However, this description is for drains typically used in tile showers with metallic shower pans and is not compatible with the specified shower stall system. Typically in a solid surface shower pan, the shower drain is 2” no-caulk shower drain designed for use with preformed shower stall bases where the drain body is sealed to the shower base with a fiber/rubber washer and mechanically compressed gasket. The drain body material will be PVC to match the new drain, waste, and vent piping. The shower drain strainer can be 4.25” diameter stainless steel. Will this type of drain be a proposed solution that is acceptable to the government? If not, please clarify what type of drain to use.

ANSWER: Provide and install 2" diameter no-caulk shower drain designed for us with preformed shower stall bases where the drain body is sealed to the shower with a fiber/rubber washer and mechanically compressed gasket. The drain body material will be PVC to match the new drain, waste and vent piping. The shower drain strainer will be 4.25" diameter stainless steel.
