Refrigeran t

Section 23 81 00 cites ASHRAE 15 and 34 (2022) but does not specify an acceptable refrigerant for PTHPs.

AIM Act phasedown has effectively eliminated new R-410A PTHP production. A2L PTHPs (e.g., R-32) serving sleeping quarters are high-probability systems under ASHRAE

15, requiring refrigerant leak detection and occupant notification not addressed in the current spec.

Confirm: (1) A2L PTHPs are acceptable; (2) whether ASHRAE

15.2 compliance is required; (3) whether refrigerant leak detection integrated with MNS/fire alarm is in the DB contractor scope.

Per ASHRAE 15 (2022 and

2024) section 7.5.2.1 these systems are exempt from high-probability status due to containing less than 6.6lbs of refrigerant. No leak detection is required as long as the refrigerant charge is less than the m1 allowable limits under

ASHRAE 15.2 (2022 and

2024) 5.3.1 and Table 9-1. If those limits are exceeded, or if there is another applicable requirement within ASHRAE

15 such as exceeding overall refrigerant limits, then leak detection integrated with

MNS/fire alarm will be in the

DB contractor scope.

Can the location of manhole MH57L be confirmed? The location noted on the site plan V-106 doesn't seem accurate. This looks more like a low-voltage handhole serving the secondary conductors to 4201.

If an alternate or more optimal tie-in location for medium-voltage power can be identified and implemented without causing outages to other buildings, is the government open to considering alternate tie-in locations?

Yes, but the existing “Barracks

Loop” A3/A4 12.47 kV circuit must be kept intact.

Attachme nt H, Vol

1, G40

This section mentions that generally manholes aren't permitted for medium-voltage extensions and that above-ground tap-boxes are preferred for radial feeds. The RFP also states to maintain loop-feed capability through all new transformers. Being able to pull multiple sets of MV conductors through shared manholes to allow for loop-feed topologies is much simpler and requires significantly fewer structures than installing tap-boxes at all UFC 3-550-01 driven locations.

Can manholes be utilized for this project in addition to tap-boxes?

Manholes are allowed, but all taps on the existing “Barracks

Loop” circuit must utilize above ground junction boxes.

A 3-way duct bank from a manhole to a JB is required with the tap from the junction box going back through the manhole and then to the transformer. But two new conduits from an existing manhole to a new transformer should allow for the exiting

“loop” to be extended to a new transformer without a tap.

Where cables would require in-line splices to extend to the new transformer(s) location(s), the existing cable should be replaced with new that goes back to the previous and/or next transformer.

Attachme

1, G40

Its mentioned that underground medium-voltage splices are not permitted, however to remove the existing BEQ transformers and re-establish the loop connection with the

A3/A4 MV feeder, underground splicing in the manholes around the campus is the much more cost-effective approach rather than pulling new MV cables from the next upstream and downstream transformers/switches on a given segment of the MV loop. Can medium-voltage splicing be utilized for this project?

The requirements for the stained and polished concrete which is required in the corridors and public spaces in the project creates significant constructability and cost challenges.

Suggest changing the requirement to a surface stain and polish system or an alternative high performance flooring system such as the C302002 Terrazz

Floor Finishes. The ESR requires the full depth of the slab to be integrally colored and 2 different colors. To construct the slabs large pours are standard and breaking up the slab into specific rooms will be non-typical and costly. Since the corridors run the entire length of the building this floor finish and its integral color requirement will impact a large portion of the building. Also, large areas of stained and polished concrete are difficult to maintain consistent finishes on making the final approval of this type of system difficult and possibly more costly.
