About this file
This file contains presentation slides from a 35% Design Review Meeting for the Bomber Agile Common Hangar (BACH) project at Tinker Air Force Base, presented by Mason & Hanger + Mead & Hunt Joint Venture in February 2024.
The slides review the design progress for a 4-dock aircraft maintenance hangar facility, including civil/site design details like towway specifications (75-ft wide full strength pavement with 50-ft shoulders, 125-ft clearance from centerline), grading plans (2-3% transverse grade, max 3% longitudinal grade), and drainage requirements (10-year storm frequency design). The design team includes specialists across multiple disciplines including civil, structural, mechanical, electrical, architectural and other engineering fields. The presentation materials cover safety information, project team introductions, review of the DD1391 documentation and statement of work, and detailed design reviews by discipline. The facility will support B-52 and B-21 bomber maintenance operations, with project objectives focused on providing Tinker AFB with an efficient aircraft maintenance hangar that meets functional needs.

Very Likely – 90% Probability/Likelihood of the risk occurring.
Occurs often or is continually experienced.
Likely – 60% Probability/Likelihood of the risk occurring.
Occurs several times over the duration of the project.
Negligible – No impact to the project.
Generators/transformers/automatic transfer switches are expected to be one year or more. The team is investigating providing an Admin NTP ahead of a construction NTP in order to get the generators and H\VAC on order.

Minor – Little or no impact on project accomplishment.
Im p ac t
Se ve ri ty
Impact / Severity
Need sufficient structural support for the foundation. Geotechnical instability could result in the need for design changes/increased construction costs. Will accept the risk until the geotechnical investigation is complete.
Design team will research and provide data to the KTR
Unforeseeable – 0% Probability/Likelihood of the risk occurring. Can assume it will not occur.
Probability / Likelihood
Example: Covid impact on construction costs, or other errors in determining an adequate cost estimate
Risk of multiple design firms failing to coordinate appropriately.
Possible – 40% Probability/Likelihood of the risk occurring.
Occurs sporadically.

Attachment 5: Post-Charrette Finalized Floorplan
Description of changes since Charrette:
•To meet life safety codes, we had to add a third stair at AMXS in order to maintain the common path of travel distance. AMXS small and medium conference rooms were mirrored to accommodate these stairs.
•Restrooms/breakroom on Northwest portion of building was rotated to correct proportions of the breakroom and prevent a dead-end corridor.
•The Northern utility spine was mirrored to allow access to the second Dock Office from the large, centrally located corridor.
•Hazardous Waste/Hazardous Storage were swapped with PSC/Dock Office per Government request to consolidate all of the tool crib attendants, their admin, and functions.
•Door was added for egress out of Hazardous Waste/Storage.
•Fire pump room door was relocated for exterior access.
•Rather than one large electrical room upstairs, the electrical engineer requested three smaller rooms centrally located across the floor.
*Please note, this is the finalized plan going forward to 35%.

Bomber Agile Common Hanger (BACH) – LCCA Plumbing Meeting
This confirms and records our understanding of the discussions which occurred, and the decisions reached during this meeting. Unless notified in writing within seven days of the date prepared, we will assume that the
Domestic Hot Water:
• Have preliminary load calcs - in folder Bob shared
• 270 gal/hr, emergency showers - deliver 150%, ESEW requires 210 gal hot water storage
• Energy model inputs for domestic water heaters:
o tank size (gallons) o capacity (kW) o efficiency (%, COP) o flow rate (GPM) o temperatures (F supply and return)
• Alternatives o Electric resistance - baseline, o Heat pump (air vs water),
▪ A.O. Smith - air source heat pump - temp 40-110 degrees, would need to be indoors
▪ \\corp.meadhunt.com\sharedfolders\entp\3167300\232112.01\TECH\disc\plumb\05
RMM\
▪ Shorter life? Would factor into LCCA
▪ Look at air & water options? Dependent on chilled water for HVAC decision
▪ Bob will send us cut sheets of options looking at o 30% solar hot water requirement
▪ Taking off buildings on current base - don't maintain properly, maintenance costs high o Tankless? (not great option) – don’t recommend including
• DOE tool for solar - LCCA etc. Domestic Solar Water Heating Calculator, downloadable spreadsheet

LCCA Modeling:
• Cost estimator to help with LCCA? Ask Scott for contact
Alternative Water Sources:
• Planning on underground storage tank for stormwater – confirm if storing both water from rooftop and pavement?
o Rainwater generally clean/can filter, pavement drainage not very clean o Separate tank would be expensive, if already have a tank we could use for rainwater collection it would reduce cost
• Rainwater better for plumbing - flushing for 35 toilets/8 urinal, Occupancy 190,
• Process water? no landscape or aircraft wash, no current process water from HVAC o Cooling tower - if have, could use non-potable water
• Need flow test data - might need booster pump, plus separate rainwater pump, cost dependent on required booster pumps
• Bob can provide list of added items for non-potable water system for cost analysi
• Larger tank + day tank – temperature of water in storage doesn't affect

Meeting Notes
Graphic Ideas – Kristin Kraft
• Historical wall at the entrance has been approved.
• Base has a Historical Officer. Would be point of contact for photo requests.
o Team would like to see a history of bomber maintenance.
• Will not be moving forward with the silhouette image in the training room, due to concerns of graphic longevity and resiliency.
o They have had to manually scrub them in the past; preference is for the training rooms to be blank.
• Mural in break room has been approved.
o Oklahoma feature graphic: commenter thinks we should tie the history with Oklahoma.
• Insignia logos will be most likely located in a break room but will ultimately be up to the users.
o Does not want it to be wallpaper or paint, should be something easily changeable.
• Way-finding ideas were declined due to the small number of visitors.
Issues and Items to Consider
• B-21 and future user groups o When the B-21 comes along, users may want to personalize spaces due to pride of working on the aircraft.
Should give the B-21 space to personalize.
Common areas are where we can focus the graphics.
• Durability o Vinyl wallpaper tends to not hold up very well, leaning towards 3form or paint.
• Maintenance o This year will be around for 50 plus years and needs to stand the test of time.
• Location of Graphics o Break rooms, hallways, and larger entrances are where they should be focused.

• Exterior Color Palette o Have more freedom to choose new palettes as this is a new building on a new campus, so it does not need to match any existing palette.
o Preference is gray scale.
• 35% Submittal o Will outline the type and location of each graphic.
o There will be a separate graphic schedule.
• 65% Submittal o Rendering can occur at this point or show wall elevations.
Future Graphics Meeting Scheduling
• Looking at February or March 2024.

Bomber Agile Common Hangar (BACH) – OCWUT Meeting
This confirms and records our understanding of the discussions which occurred, and the decisions reached during this meeting. Unless notified in writing within seven days of the date prepared, we will assume that the following documentation is complete and accurate.
Meeting began with introductions of attendees.
Discussion started with the review of RFIs 20 and 31. RFIs request information on the domestic water supply.
After the group agreed that fire flow was a separate topic, the conversation focused on the 12” domestic water supply.
OCWUT representatives stated that existing flow data does not exist. Additionally, with the proposed project improvements to the campus, any existing flow data would not be accurate for design purposes.
For design purposes, OCWUT representatives stated that OCWUT is required to provide 50-70 psi operating service pressure for domestic water.
Given the above information, the plumbing designer, Bob Mutsch, stated that he could use this information to progress with the design.
With the concurrence of the group with respect to information for design purposes, the meeting was adjourned.

DD1391 and other
Categories: Red Category
All, We had a call with Ron Rosebrook, Rafael Gonzalez, Patrick Buhler, and I this morning at 10:00 am to discuss the addi onal airfield pavement ques ons below.
Regarding ques on 1: The AE is to proceed with the addi onal paving beyond what was documented in the 1391. It does not need to be priced as a separate line item and should be included in the total pavement es mate for the 35% review. It is understood this addi onal pavement is necessary for a successful design and mission.
Regarding ques on 2: Replacement of the exis ng towway pavement between Douglas Blvd and the new BACH pavement is not being considered currently. It is understood that this pavement is likely to degrade more quickly from the adjacent new pavement. This could require a shutdown of the towway and hanger in the future. No RFI is necessary.
Please let me know if there are any ques ons or concerns with these responses.
Thanks, William (Clint) Rodgers, RA, NCARB

Clint, BLUF: Two topics\issues. 1)The airfield pavement areas in the project currently under design differ from the areas listed in the DD1391. Below in 1) is a narra ve describing and detailing this difference.
2)An RFI is proposed in 2) to replace the exis ng towway pavement sec on with a thicker sec on per the designed PCC pavement sec on. This would result in an increase in the project scope and cost.
Below from Patrick Buhler -
1) Upon generating the airfield paving geometric layout, it is apparent that the quantities listed on 1391 and the Final Bomber Planning Document did not account for the need to include 50’ wide paved shoulders on each side of the existing towway, which is also being widened to 75’ PCC. In addition, during the charrette there was a project requirement generated to provide additional PCC to the southeast of the proposed hangar for a B-52 parking spot, which will be used to store the B-52 aircraft stands during maintenance operations. The additional airfield pavement required for the 50’ wide shoulders and the B-52 parking spot equate to approximately 9,200 SM of additional area that is not currently included in the 1391 quantities. Therefore, should the construction cost for these two items be shown separately from the rest of the project scope items in the cost estimate for the 35% deliverable? ***Scott’s note – The areas and subsequent quantities above were discussed during the design charrette and included in the out-brief presentation. I do not believe these should be separated out as requested but certainly discussed in the upcoming 35% review as it pertains to the revision of the DD1391.***
2) Also, it is strongly recommended that it be considered to add to the project the replacement of the existing towway, which was planned to remain in the 1391 and the Final Bomber Planning Document. The concern is that the existing PCC on the center of the towway is 16” thick. The proposed pavement section included in this project is approximately 22.5” PCC, on 5” Drainage Layer, on 4” Aggregate Base Course separation layer, placed on a 12” Lime Stabilized Subgrade. Not including replacement of the center section of the towway will result in full strength pavement only being located along the edges. This is the opposite of what should occur as the existing slabs to remain are also the more critical slabs as they will see the majority of the aircraft main gear load. Therefore, the actual loading from the aircraft will be carried by the existing 16” thick PCC section to remain. *** To note *** if the existing towway pavement were to remain in place, any repair or replacement required to the existing towway pavement in the future would pose a construction phasing challenge as the towway would be the only access pathway to the new BACH location and would\will be located in the middle of the towway. Therefore, any future repair project will require access to the BACH be restricted during the entirety of the project. Please advise if the replacement of the existing towway should be included in the design of the project as a separate scope item with the cost also being included as a separate item in the 35% deliverable.
If you concur that an RFI is in order for 2), we will generate and issue one immediately.
Thank you, Scott Nall PE

Bomber Agile Common Hangar (BACH) – LCCA Results Meeting
This confirms and records our understanding of the discussions which occurred, and the decisions reached during this meeting. Unless notified in writing within seven days of the date prepared, we will assume that the
Life Cycle Cost Analysis Results presentation of the Life Cycle Cost Analysis (LCCA) by Mead and Hunt. Overview of process and requirements by Federal Guiding Principles, UFC, and Executive Order for electrification. This included whole building energy modeling for different all electric design alternative energy efficiency measures (EEMs) to demonstrate a 30% energy cost savings over an ASHRAE 90.1-2019 Appendix G baseline, as well as life cycle cost effectiveness (LCCE) compared to the base case over a 40 year period. Each option was analyzed for both energy cost savings and a 40 year net present value for LCCE.
To meet the above project requirements, it is recommended to implement ALL of the following all electric design options (broken out by discipline). These options bundled together meet the 30% energy cost savings and are LCCE.
• Architectural o Roof Admin Alternate 2 (RA-IEAD-A2) –
IEAD of 6 inches polyiso above deck (max U-0.025, min R-40 c.i.)
o Roof Hangar Alternate 1 (RH-SSMR-A1) –
SSMR w/ of 6 inches polyiso (max U-0.025, min R-38 c.i.)
o Wall Admin Alternate 1 (WA-TU-A1) –
Tilt Up 3.5 inches rigid insulation (max U-0.061, min R-20) o Wall Hangar Alternate 1 (WH-IMP-A1) –
IMP w/ 1 inch rigid insulation (max U-0.044, min R-25 + R-6 c.i.)
o Window Option 1 (FA-AS-A1) –
Aluminum storefront 1 inch, tinted/tempered, low-e, double pane (max U-0.25, SHGC-
0.25, VT-0.275)
o Overhead Door Alternate 1 (OD-IS-A1) – R-9 Alpine IMB-V9, 1 inch polyurethane (max U-0.11)

• Electrical o Interior Lighting Power Alternate 1 (LT-LD-A1) –
0.54 W/sf Admin, 0.64 W/sf Hangar
o Solar PV Option (PV-A1) –
Hangar roof south PV array, approximately 420 kW-DC array Structural concerns were discussed. Possibly mitigated with light weight racking or panel options Cost of additional structural not included in LCCA due to uncertainty of panel and racking weights and manufacturers Glint and glare issues discussed. Could have a glint and glare study conducted. FAA no longer requires studies due to panel coatings limiting glare and glint being unavoidable from other sources such as bodies of water and glass.
Potential for other PV array types such as carport or ground-mounted arrays which would have higher first costs.
Hail concerns addressed. PV panel warranties include hail and are designed to withstand hail and wind.
Timing of roof and PV panel replacement important cost consideration. PV panel expected life between 20-25 years while roof may be much longer.
Net metering in Oklahoma limited to 300 kW included in simple payback. Electric utility rates would be commercial retail unless excess generation above net metering would then switch to avoidance rate that is lower than retail and closer to wholesale rates.
• Plumbing o Service Hot Water Alternate 2 (SW-WS-A1) –
Water source heat pump
Would use HVAC Option 1 chilled water return
• Mechanical o HVAC Option 1 – Air cooled chiller, VAV w/electric reheat, DOAS (Admin), MAU w/ electric resistance, ERV (Hangar) o Demonstrated energy cost savings of 2.6% compared to ASHRAE baseline o Flexible for future changes
Additionally, some options were considered but not determined to be LCCE and not recommended including:
30% solar hot water o 30% of service hot water load provided by solar hot water, with full sized base case electric resistance tanked service hot water system.
o Small amount of annual energy cost savings.
o Not LCCE due to larger savings from water source heat pump. Could possibly be implemented in conjunction with water source heat pump system.
Rainwater harvesting o 30,000 gallon underground storage tank, with (3x) variable speed pumps, treatment skid, transfer pumps, primary and secondary filtration, UV sterilization, 300 gallon day tank.
o Not LCCE due to low water cost savings and inexpensive water utility rates compared to high first cost and maintenance costs.
o Discussion on location of storage tank above ground. Would require additional structural and be at risk of accidental damage, but could be cheaper to maintain than underground.
HVAC Option 2 – o Packaged RTU heatpump, w/ DOAS heat pump, electric resistance reheat, ERV (admin).
o MAU w/ heat pump heating, electric resistance backup (hangar).
o Demonstrated 11.2% energy cost savings compared to ASHRAE baseline.
o Not LCCE compared to base case due to maintenance and replacement costs associated with multiple RTUs and limited size of heat pumps.
o Heat pumps operable down to zero Fahrenheit and would require electric backup for temps below zero.

HVAC Option 3 – o VRF heat recovery and w/ ERV (admin).
o MAU heat pump (Daikin Aurora or equivalent), electric resistance backup (hangar).
o Demonstrated 15.6% energy cost savings compared to ASHRAE baseline.
o Not LCCE compared to base case due to higher first cost, maintenance, and replacement costs.
o UFC 3-410-01 c8 has special requirements for VRF systems indicating concerns associated with proprietary hardware and software in conflict with 10 USC 2867, risk of leaks from high amount of refrigerants in VRF systems, and uncertain life-cycle costs compared to traditional HVAC systems.

Bomber Agile Common Hangar (BACH) – 35% Design Review Meeting
This confirms and records our understanding of the discussions which occurred, and the decisions reached during this meeting. Unless notified in writing within seven days of the date prepared, we will assume that the
Day 1 Project Team Introductions & Opening Remarks
• D. Hensley opened the meeting with a greeting to those attending and then proceeded with introductions.
35% Design Review Goals & Objectives (DD1391)
• S. Nall gave a brief overview of the purpose of the meeting; review goals and objectives of the 35% design. The disciplines would provide a brief review of their deign intent and direction followed by a review of the cost estimate, construction schedule and sustainability and guiding principles review on Day 1. Day 2 would primarily be a discussion of the Dr Checks items other than ‘Concur’ that were in the system.
Project Review – Civil/Site
• Patrick Buhler reviewed the applicable geometric design requirements of UFC 3-260-01
• Site accommodates up to 200-ft wingspan aircraft which locates the towway clearance line 125-feet each side from centerline.
• It was noted that towway full-strength pavement is 75-feet wide. This will provide flexibility to perform repairs on half of the towway while using the other half to still tow aircraft.
• Matt Detoy noted that the utility corridor and other utility locations will need to be installed at elevations under this project that will mesh with the future bomber campus. Grading will be coordinated for all utilities, so they are set at appropriate elevations with the future bomber campus being considered.
• Carmie Ashley suggested checking grades on eastern edge of towway to ensure we aren’t creating problem spots for future campus construction.
• Patrick Buhler reviewed grading concept and storm sewer infrastructure plan. It was noted that storm pipes and inlets are sized for 10-year storm events and account for the future bomber campus plan development to the south.
• Detention basin is only being sized for this project.

• Patrick Buhler reviewed the PCASE pavement design inputs and proposed pavement section. It was stated that the Geotech results are still pending, and the data used for the 35% was utilized from KC- 36A campus.
• It was noted that survey results are pending and existing topography shown was from public LIDAR data and existing site linework provided was from Tinker GIS data.
• Representative from OCWUT stated that if a utility crossing is required at 59th Street, the City of OKC may require that it be bored.
• A second gate from the POV parking lot was discussed. Second gate to be a man gate as opposed to the existing vehicle gate.
• It was noted that the base is not under City of Oklahoma City requirements.
• It was noted by Tinker representatives that there is a surge in POV parking. Shift changes drive more available parking spaces.
• Tinker representatives noted that the utility corridor may need to be wider than the proposed 20-foot.
Manholes along the corridor should be sized (height) for the ultimate condition not a temporary solution. Final campus earthwork contours.
Project Review – Architecture
• R. Siler provided a review of the architectural design standards, UFC and other criteria.
Project Review – Interior Design
• C. Fernandez provided a review of the interior design standards, UFC and other criteria.
Project Review – Mechanical/Plumbing
• R. Carter provided a review of the mechanical design standards, UFC and other criteria.
• Floor drains at eyewash stations: UFC doesn’t require. Base representatives directed to not install.
o Portals in hangar door: 16” square. Will likely require man-bars for SAPWA.
Project Review – Electrical/Communications Electrical:
• Project scope includes demolition of existing power stands on the project site. The team was reminded that documentation of the existing work will be required to provide the construction contractor information sufficient to include the demolition scope in his proposal. It was noted during the meeting that a related RFI would be submitted.
• Project scope includes modification(extension) of existing parking lot lighting system on the project site.
The team was reminded that documentation of the existing work will be required to provide the construction contractor information sufficient to include the extension of the parking lot lighting to light the expanded parking lot in his proposal. It was noted during the meeting that a related RFI would be submitted.
• Project scope includes modification(extension) of existing fence line lighting system on the project site.
The team was reminded that documentation of the existing work will be required to provide the construction contractor information sufficient to include the modification(extension) of the fence line lighting in his proposal. It was noted during the meeting that a related RFI would be submitted.
• Site lighting fixtures mounted above 30 feet high were discussed. A RFI will be submitted to clarify the special review noted in the Tinker Electrical Standard.
• Building obstruction lighting was discussed and it was noted that the proposed hangar is outside the base BRL line(s). An RFI will be submitted to clarify the requirement for obstruction lighting at the Bomber Agile Common Hangar.
• Routing of power cabling from hangar bay power stations to the hangar bay floor. Subsequent design submittal will propose a solution. A RFI will be submitted to determine the overhead clearance requirements.
Communications:
• There will be IP TV with network cable distribution for the TV system.
• Show TV riser diagrams.
• Room 119 is potential vault storage.
