Ventilation: Per ASHRAE 62.1-2022 and UFC 4-211-01

Mechanical – Design Review

Typical Air Handling Units

Central station AHU’s will be 100% recirculating (no outside air), have chilled water-cooling coils sized for 30% propylene glycol, VAV fans with VFD’s for duct static pressure control, 4” MERV 8 prefilters and 4” MERV 13 final filters. Construction will be minimum 3-inch-thick insulated walls suitable for indoor installation. These AHU’s will deliver 55°Fdb air to VAV air terminal units equipped with electric resistance reheat coils. The VAV terminal units will modulate the quantity and final temperature of the supply air to maintain zone temperature.

Typical Dedicated Outside Air Systems

DOAS will deliver tempered (70°Fdb, 52°Fdp) 100% outside air directly to each space. Dew point will vary to meet latent loads. Additionally, the DOAS units will exhaust air from various spaces including restrooms and shop areas. The exhaust air and outside air will pass through a crossflow plate energy recovery system (ERV) to exchange energy between the exhaust and outside air streams. Each DOAS will have both exhaust and outside air flow rate monitors for building pressurization control.

Makeup Air Units

MAU’s will deliver supply air for ventilation and heating as well as exhaust air from the space. These units will have electric resistance pre- and heating coils, MERV 8 outside air filters, MERV 13 final filters, supply and exhaust fans, and a cross flow heat exchanger. These units are heating and ventilating only with no cooling. The outside air will bypass the heat exchanger in the summer.

Air-Cooled Chilled Water Plant

The air-cooled chilled water plant will consist of a single variable speed air cooled chiller with redundant primary and secondary pumps. Primary pumps will be constant volume. Secondary pumps will be variable flow and controlled through VFD’s to maintain a differential pressure setpoint in the chilled water distribution system. The chilled water will be 30% propylene glycol to prevent freezing.

Ductless Split-System Heat Pumps: Ductless split-system heat pumps will be used to provide temperature control for dedicated spaces such as fire alarm rooms, data rooms, and comm rooms that require conditioning during unoccupied periods.

Unit Heaters: Electric resistance unit heaters will be used to heat smaller heated only spaces such as mechanical and electrical rooms.

Cabinet Heaters: Electric resistance cabinet heaters or electric resistance convectors will be used for vestibules and other spaces that require supplemental heat.

Dr Checks Comments Review

Civil – Comment 10621968

• Existing Towway Widened to 75’

• Comment 10621968 suggests to investigate straightening towway

• Response: Replacing the existing PCC was discussed but instructed to keep in place. Not included in 1391 and currently out of scope.

Civil – Comment 10621978

Response: Proposed C/L is consistent with the C/L location in the Final Bomber Planning doc. The image from the Final Bomber Planning Doc shows the centerline 150' east of the ACH. Proposed C/L is 150' east of the ACH with a full strength towway width of 75'

Civil – Comment 10621982

Is it possible to add and additional row of POV parking along the south side of both the new lot and the existing lot? See Attachment.

It may be possible to add the additional row of POV parking. We will know once the survey and easements are completed and shown. We will either add the spaces or explain why parking can't expand south for the next submittal.

Civil – Comment 10641038

Clarification: Will Douglas or SE 59th be bored for water or sewer? Applicable specs may be needed. The Sanitary Sewer Force Main Piping may be needed, unless it's included in the Packaged Utility Wastewater Pumping Station.

Current plans do not require a specific method but do require that if trenched, the contractor must provide coordination/traffic control. We can require all crossings to be bored if that is the preferred method. Will include specification for Sanitary Sewer Force Main Piping. Currently showing Sanitary Sewer connection into the existing system north of our site, not across Douglas.

Please refer to construction limits on GC111. The connection information to the existing system will be better defined in the next submittal.

Civil – Comment 10641490

Do these markings comply with UFC 3-260-04 Para 6-1 and 6-2? Towway centerlines should be 6" wide yellow. At the end of the arc as the line enters into the hangar the line should be 6" wide white. Remove the non-reflective black background paint.

All aircraft are to be towed to the ACH and within the future B-21 campus. Paragraph 6-1 and 6-2 refer to taxilane and taxiway markings for powered aircraft, which does not apply to this project site. Towway markings per 6-5.9 of UFC 3-260-04 are to be white as shown on plans.

The black border is recommended per the UFC on light-colored pavements (PCC), especially with white markings.

Civil – Comment 10641512

Comment: Show new pavement for AGE parking that will be demolished by the project between B2301 and south of B2300

Civil – Comment 10641515

Existing utilities need to be removed under the towway in addition to the 18" and 24" culvert crossings being installed. Due to the size of the culverts, boring and jacking as an installation method will be costly. In future submittals restrictions can be provided on the phasing plans to expedite the construction work in these areas to limit the effects on towway operations.

Require that both storm drain crossings of towway be bored instead of trenched.

Civil – Comment 10641518

Comment: Verify sufficient room on ramp to turn B-52 into crabbed position and push it into the hangar on the east side

Civil – Comment 10641520

Comment: Show dimensions of modified keel section of existing east-west towway and new north-south towway

Civil – Comment 10641534/35, 10641568, 10643456

10641534/35 Show B-52 crabbed wheel lines into hangar as well as centerlines.

Please provide operational pavement markings for B-52 crab movements. These are not covered in the UFC.

10641568 Add additional personnel gate at existing personnel gate due to increased personnel flow.

Will discuss at the review meeting for confirmation to add additional personnel gate and to verify no other infrastructure will be required (additional guards or lighting).

10643456 DA. Civil 2.3.8. Airfield aprons, taxiways pavements to use 5-year storm event for analysis as indicated in UFC 3-201-01, 3-1.2.1. Please verify, confirm and adjust as necessary.

Per paragraph 3-1.2 of UFC 3-201-01, this project is using the facility storm drainage requirements of 10-year not the airfield minimum of 5-year due to this project being located within a building campus and not within the Aircraft Operations Area. Typically, an airfield is a pond and culvert system where this facility is fully reliant on the storm sewer network to project the buildings.

Civil – Comment 10643458

10643458 Is there a master drainage plan for the whole campus?

I would think these were discussed during the campus development and design charrette.

Although the reference guide of OKC drainage manual is a good start, the governing drainage criteria should follow UFCs unless this campus has been decided to follow OKC drainage criteria.

There is a master drainage plan in the final bomber campus plan. Storm sewer infrastructure included in this project is designed to accommodate the future bomber campus to the south of the ACH. As discussed during the charrette detention will be designed only for this project as the B-21 infrastructure project to include the perimeter road and detention area has not been completed. UFC 3-201-01 paragraph 3-1 states to use the storm drainage criteria listed in the UFC or local regulatory agency; whichever is more stringent. The local OKC drainage manual and guidance will govern design parameters.

Thanks for the masterplan info.

But I was not able to locate such info. I was able to locate the drainage maps starting on PDF page 881, but these don't seem to be for all the campus and was some of the off-site on the south.

UFC 3-201-01 paragraph 3-1, "local criteria" applies only when the local criteria agency has jurisdiction over the installation. I don't believe OKC has jurisdiction over the stormsewer improvements on base or will have once the new campus is complete. Base typically operates and maintains all stormsewer infrastructure on base unless this has changed recently.
