Civil – Comment 10643470, 10643473

10643470 Site plan. Will sidewalk or walkway be provided from the POV to the Hangar? Or is intended to use the existing sidewalk that goes to MROTC.

This project will provide a sidewalk along the northern boundary of the POV parking lot to the personnel gate. There are currently no new sidewalks being provided from the personnel gate to the hangar.

10643473 Utility corridor. Arch plan shows a 20' wide corridor.

Consider a wider utility corridor path and provide a preliminary utility trench configuration showing all the possible utilities for this campus. KC-46A utility corridor has become a congested corridor due to poor planning and narrow width.

Please, provide direction from Base CE (Matt DeToy).

Civil – Comment 10643481, 10643507, 10643520

10643481 The utility plan is lacking or missing other utilities such as industrial waste, breathing air, telecom, power, fuels and fuel pits(if applicable), dedicated fire mains(if applicable), etc.

The current design does not include industrial waste, breathing air, or fuel lines serving this hanger from off site. The site telecom and power information will be shown in the electrical/communications site drawings. A dedicated fire main will be shown in the next submittal running from the existing fire main west of Douglas, parallel to the domestic water line, to feed into the north and south sides of the proposed hangar.

10643520 Indicate if there will be designated dumpster areas for this hangar?

Government to provide direction regarding any necessary dumpster areas.

10643507 DA. Pavement design. Please confirm or indicate what's the pavement design life. Unless I overlooked it.

The standard traffic pattern utilized by the Air Force is based on 20-year life. Will add to the DA.

Thank you. Please ensure this is clear for airfields and and site roads as applicable. FYSA. Site roads require a 25-design life if applicable.

Architecture/Security - Comment 10641007 10641007 Attached are my initial findings in looking at the room to be built/provisioned for future SAP use by us. Mr. Liles is communicating with B52 stakeholder to ensure they have absolutely no need to utilize this space to store/process/discuss collateral or SAP. So far he is hearing they do not need the room at that level; however, is confirming they have no intended use for that space until we take over the facility later down the road. In provisioning the room for us, ICD 705 needs to be applied and the issues noted in the attached/below need to be remedied. With that, we need to understand from Mr. Akin how he would want the room protected between when build is complete and we take ownership and plan to bring that room up to SAP level. I would think if B52 is not going to use the room, an X10 should be placed on the main entrance and controlled by us until later but that is AO PSO call. At a minimum, security requirements for physical and TEMPEST need to be factored in now (z ducts, inspection ports, man bars, dielectric breaks/grounding, conduit in place for ACS/IDS pulls later) so the room does not need to be torn apart and reworked.

Our next concern is that none of the SAPWA requirements for the Hangar bays have been planned in to provision it for that level of work for us later. Mr. Taber has stated it will need to be able to go up to SAP levels in future when we take ownership. We believe we should build to the standard JT has outlined for MOB facilities now with the exception of installing IDS/ACS, secure locks, etc. We strongly urge we consider planning in the following:

- Z ducts with manbars, flex ducts or grounding, and inspection ports on the secure side

- Dielectric breaks or grounding for electric conduit/water piping

- If metal fiber trays run through the space, they need to be looked at closer. i.e. they should not penetrate secure boundary and should be grounded

- Roof hatch assemblies with no external hardware that can be secured on the inside with conduit available to tie them into the IDS later

- Conduit in place for future IDS to include adding BMS's at the perimeter doors (main entrance, emergency egress, hangar doors, roll up doors, etc)

- ID location for IDS/ACS panels contained within the SAPWA boundary

- Sound attenuation is not as concerning here where we need to rework walls understanding the SOP JT has laid out for the MOBS when it comes to discussion in the bays

Architecture/Security - Comment 10641007 (Cont.)

10641007 ICD 705 will be applied with concerns mentioned above. An X-10 will be considered and confirmed with AO PSO.

For future SAPWA requirements, design will consider all construction techniques mentioned above.

Architecture/Security – Comment 10641007 (Cont.)

Please, confirm this room is to be designed to ICD 705 version 1.5.1, 26 July 2021. Also, confirm TEMPEST is a requirement.

Previous direction was that it was not required and therefore has not been designed as such.

Please, provide AO PSO contact, so we can coordinate design submittal reviews with them.

Comment refers to SAP and SAPWA. Please, confirm that we are to design to DoDM 52.05.07- B3 April 23, 2015, change 3 12/08/2023.

Is RF Shielding required?

*MOB facility guide.

Architecture – Comment 10641499

10641499 Make sure storage (such as lockers and or desk drawers) inside the hangar bay are above 18" AFF to maintain the Class 1 Div 2 rating.

Talking with our FPE, NFPA 70 requirements for Class 1 Div 2 rating is to have no powered devices less than 18" AFF in the hangar bay which could provide enough exposed energy to ignite an explosive concentration of vapor. The interior designer will specify lockers that do not have power and that meet NFPA 286 Class A rating. She also noted that the desks at the hangar bay currently do not have storage below 18" AFF. Any power requirements will be coordinated with the electrical engineer.

Architecture – Comment 10621987, 10641542 10621987 Kind of confusing when overlaying the outlines of the future campus. In particular, what are the lines just across the towway across Douglas?

10641542 Recommend to remove future facilities from this plan as they appear incomplete and confusing.

Please, provide direction as to what you would like us to show with regards to future planning. (This can be a separate civil sheet used for internal planning purposes only – Not For Construction.)

Architecture – Comment 10621990 106219990 Request we find a way to get the Dock Office rm 108 moved to the North so they have a window onto the hangar bay. See attachment for options.

The design team can make the attached revision work. We will discuss further at the review conference to get concurrence from all reviewers.

Architecture – Comment 10621999 10621999 Request we take the Stairwell 10' above the roof eave and provide a 4' door onto the roof. See attachment for reference.

The design team should be able to accommodate this request. We will discuss further at the review conference to seek consensus amongst all reviewers.

Architecture – Comment 10641545, 10641548 10641545 The amount of brick looks excessive. In the KC-46A campus we usually have a wainscot up to about 4' AFF.

The wall construction is different since we opted for precast concrete sandwich panels for speed of construction and durability.

10641548 The color of brick does not seem to match the intent of "Creech Brown" standards because of too much red.

TAFB Facility Standards for District C (closest district to our project) lists Garnet by Acme as a basis of design for exterior brick. This is not available as a thin brick, but selection chosen is close to this color and complements it. At the charrette, it was discussed that this was a new campus and that they were open to a new color palette.

If the pocket grows to incorporate the additional requested space, this has an impact on the coordinates provided by the base CE (Matt Detoy) set point for all hangars in the future. *Limited opportunities to grow hangar (1'-4"). Possibility to eliminate corridor at Area B only, travel distances not met in Area C/D with this approach. Please, advise.

Architecture/Structure – Comment 10643381 10643381 General Comment: Wall sections show architectural precast concrete panels with thin brick veneer. Please ensure that the thin brick is mechanically attached to the panel and not adhered when the specification is created. Adhered thin brick is susceptible to detaching in the frequent freeze-thaw cycles in Oklahoma.

We plan to integrally cast the thin brick into the concrete panel. Our BOD thin brick conforms with ASTM and PCI standards. PCI Architectural Precast Concrete manual states:

With thin-brick units, no metal ties or weeps are required to attach them to the concrete because adequate bond is achieved. In general, clay products that are cast integrally with the concrete have bond strengths exceeding that obtained when laying units in the conventional manner. Thin bricks conforming to PCI standard have lower water absorption than conventional brick. In addition, thin brick is less susceptible than conventional brick to freeze-thaw issues, spalling, and efflorescence.

Lunch Break Reconvene at 1200hrs

Structural – Comment 10641764 10641764 Provide verification that all connections from the host building to the storm shelter are designed to the ultimate failure of the connection, per ICC 500-2020, section 304.9. This includes foundation elements, such as grade beams and slab-on-grade. Recommend to disconnect the storm shelter foundation elements from the host building. Recommend providing an additional adjacent pier and grade beam system at the boundary between the host and storm shelter buildings.

The storm shelters are currently detailed to be completely isolated from the host building. The foundation shown for the shelters is a soil supported mat foundation. Once the geotech report is received, we will either confirm the use of the mat foundation or utilize grade beams and piers that are isolated from the host building.

The submitted foundation drawings do not appear to currently indicate a separate foundation from the host building. Clarify the response.

Mechanical

10634850 Mechanical Design Analysis Sec. 6.3.2. pg 73

Instead of MERV 8, use MERV 13 for pre-filters in order to adequately protect (and extend) the life of the equipment.

Comment provided by Sara Sayler.

Evaluation: Check and Resolve

Typically at Tinker AFB, we have been requested to use MERV 8 prefilters followed by MERV 13 final filters. Although labeled as final filters, they come right after the pre-filters and before any coils or fans. These should not be confused with clean room type final filters that are located after the fan. Please confirm MERV 8 prefilter are not desired to extend the life of the MERV 13 filters.

10641572 Mechanical Design Analysis Sect 6.3.2

What level of filtering is accomplished on incoming air for the DOAS? Requesting capable of filtering fumes, jet fuel, and gaseous contaminants. Southwest of this hangar will be the primary engine runs spots. Common issue with existing hangars near run spots is the HVAC system pulls in fumes taking hours to dissipate. Submitted by Dustin Baker.

Evaluation: Check and Resolve

Carbon filters can be installed in the outside air stream of the DOAS units. However, these filters are fairly expensive to install as well as very expensive to maintain. They require frequence maintenance with either regeneration or replacement. Please confirm this is the direction the Government wishes to take and also confirm whether gas-phase filters should be installed on all OA intakes including hangar bay ventilation units.

Submitted by D.Delsigne

Evaluation: Check and Resolve

Pipe and connectors will be provided as requested; however, we need to know what the service is (flow and pressure) and/or the type of pipe and fittings. Also, will need to know what connector are needed.

10643000 Mechanical Plans

Document Reference: M-100s Add installed bottom of duct heights,VAV numbering helps to match room numbers,HVLS fans are light at nose of plane. Submitted By: Eric Slater.

Evaluation: Check and Resolve

1. BOD elevation will be added at a future submittal. Probably after the 65% stage.

2. VAV's do not correspond to room numbers and it would be confusing to have VAV boxes numbered after a room it is located in when it serves another room or if two VAV's serve the same room.

3. Agree, but the aircraft is not being ventilated. The fans are to increase the circulation within the space to minimize dead spots. We are trying not to blow down directly on the AC. Please advise if more HVLS fans are desired.

10643099 Mechanical Plans

Document Reference: M-schedules

I believe UFC only allows up to 6 row coils. Submitted By: Eric Slater

Evaluation: Check and Resolve

I cannot find the requirement stated, please furnish the reference since it is generally desired to have an 8 row coil to maintain a decent chilled water delta T.

10644163 Mechanical Specifications 23 25 00

UFGS 23 25 00 CHEMICAL TREATMENT OF WATER FOR MECHANICAL SYSTEMS may not be deleted from the specifications. Water treatment is required per para K. WATER TREATMENT on page 18 of the TAFB Base Mechanical Standard. Submitted By: Joe Marcano

Evaluation: Check and Resolve

Typically in the past at Tinker, we have used the Water Treatment requirements listed in Section 23 64 26 Chilled, Chilled-Hot, and Condenser Water Piping Systems since it addresses chilled water and condenser water only. It has the same requirements as 23 25 00 for chilled water without all the requirements for different boilers and cooling tower systems. We feel using the same section for piping and water treatment makes for a cleaner set of specs; however, if the Government feels a separate spec section if desired, please advise.

General / Life Safety – Comment 10641585

10641585 Remove RM 104A, 104B, 104C, and 104D labels; assign square footage to RM 104.

Remove RM 102A and add SF to 102.

Non-Concurred Those are architectural model features. The occupant loads associated with those areas are collectively calculated under area #33, except 104C which is an office calculated accordingly.

Fire Protection / Life Safety – Comment 10641623

10641623 Perpendicular PPE to hangar door should continue until they intersect the hangar door hazard warning area lines. No other PPE lines is required next to hangar door. PPE Lines to be yellow.

Life Safety – Comment 10643326

10643326 SECTION 9 - LIFE SAFETY - FIRE PROTECTION, 9.1 GENERAL PARAMETERS: SF is listed as 176, 230 SF. I don't see any correlation between that number and the Program Area Comparison table starting on page 58 of the PDF. Please clarify if the 176,230 is representing a Net area or Gross area and correct if necessary.

Concurred* The calculation of building area for the IBC is the footprint area of the structure measured to the inside face of the exterior walls (generally). The Program Area in the indicated table is the total area of multiple floors and not compared to the IBC area in Section 9.

Customer DA – Comment 10634840

10634840 This specifies no natural gas service is being provided. I realize there is an electrification requirement, but should we reconsider gas service for resiliency and/or future use purposes?

EO 14057 requires electrification of buildings but does not specify if that would include connections for future usage. Adding a natural gas connection for potential future usage would be an additional cost that may not ever be used.

Cost Engineering – Comment 10643606

10643606 The design analysis (page 6 of the .pdf) states the following: "The current DD 1391 provides a Programmed Amount (PA) of $282,000,000 which includes a 5.0% construction contingency and 6.5% for Corps of Engineer Supervision, Inspection and Administration. The contract Scope of Work requires that any construction cost estimate base bid that exceeds 80% of the PA have bid options."

The CCL from the DD 1391 is is $251,551,000, so where is the requirement stated above coming from?

The DD1391 PA is $282M as stated.

Section 2.5 of our Scope of Work identifies the ECCL for this project as $239,700,000.

Section 5.14 of our Scope of Work directs us to define recommendations /solutions if that cost is exceeded.

As $239.7M is not 80% of $282M, that will be corrected in the DA.

Cost Engineering – Comment 10644685

10644685 A design contingency of more than 15% should be added to the MII cost estimate at this point.

There are still numerous unknowns in the design that could have some significant cost impacts.

We'll capture some of these risks in the CSRA/cost certification process as well.

The cost estimate is currently carrying a 20% design contingency. If the design contingency needs to be higher than 20% please advise.

Bomber Agile Common Hangar (BACH) – Airfield Pavements Discussion

Terry Helms

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

General Notes – Topics of Discussion

1. The alignment of the east-west towway portion of the proposed pavement north of the proposed

BACH.

2. Size and of the proposed PCC AGE storage area.

3. Thickness\cross section of the PCC AGE storage area.

4. Alignment of the future fire station access roadway as it intersects with the BACH project pavements.

1. Pavement alignment

NW hangar location utilizes coordinate location provided from base and is oriented true north. 125’ is the distance from hangar to centerline to accommodate a 200’ wingspan aircraft and 25’ wingtip clearance. A larger aircraft (potentially C-5) could access the east side of the ACH with an offset centerline to accommodate the required wingtip clearance; moving the existing fence near marines would be required.

2. and 3. AGE parking area

20,000 SF required. Centerline of towway is 142.5’ from B2300 and also from the future de-paint hangar (285’ feet from face of hangar to face of hangar) The pavement will be 60’ clear from the de-paint hangar and be 225’x120’. The pavement keep section will extend from centerline east to account for future hangar door locations of the de-paint hangar. Mead & Hunt to provide sketches showing proposed AGE location and cross sections. Current intent is to maintain current access drive\walkway location from the access gate and POV parking, which divides the proposed AGE storage.

4.Alignment of BACH proposed pavements with future fire station The future fire station drive connection location can be flexible as long as it lines up with one of the future engine bays. Further east may be preferred. Design for 65% will be revised to eliminate the North\South storm culvert daylighting near the future drive entrance. The strengthened shoulder will be

BACH Sanitary force main will be shifted east to line up with the current proposed fire station parking lot. Storm structures along the north side of BACH flowing east will be sized appropriately to handle additional flows generated from the proposed fire station (oversized from what is required for current flowrate + additional BACH runoff).

ACTION ITEMS:

1. Tinker to provide A\E Team with fire station background drawing information.

2. A\E Team to provide background drawing of BACH project to USACE\Tinker to align the fire station access road w/r to the BACH project proposed pavements.

3. A\E Team to provide drawing of AGE parking area with dimensions and cross section of same for review by USACE and Tinker CE for concurrence.

Bomber Agile Common Hangar (BACH) – Tool Crib/FOM Layout 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

DISCUSSION ITEMS

1. Tool Crib Layout:

a. Users requested vertical rolling carousel, rather than the current stacking high density storage.

Use Kardex Megamat 180 as basis of design.

b. Large shelving units for receiving and checking out rolling carts/chests. Leave out bottom shelf of pallet racks in order to park rolling carts.

c. Users like KC-46 layout and like Vidmar flexibility of storage cabinets at corridor and tool crib.

d. Verify aisle clearance around pallet racks for pallet jack. They aren’t anticipating driving a forklift through this space.

The Mason & Hanger Group Inc. 300 West Vine Street, Suite 1500 Lexington, KY 40507 t 859.252.9980 f 859.253.0781 masonandhanger.com

e. High density storage is not preferred.

f. Vidmar cabinets to remain in the corridor on the other side of the building

g. Ceiling height in the tool crib is easily found 15' 10" to the deck

h. Concerned about the height of things for fire protection

i. Dustin to send vertical lift information

j. Vidmar cabinets in DLA and composite? - No but still reviewing the rooms

k. Completely remove high density shelving replace with carousel

l. Eliminate double door from Hazardous storage to Tool Crib. Users request that the 3’ wide door grow to a 4’ wide door by checkout counter to hazardous storage for larger items to pass through.

m. Shift workstations by posts to prevent accidental collisions with them.

n. Align windows with aisles and orient shelving vertically as shown in Dustin’s image below.

2. FOM Layout:

a. This will be used similarly to the tool crib, but for smaller piece parts of tail bins.

b. They prefer the pallet storage aisles to run horizontally in plan vs. the current vertical orientation. Request roughly 8 pallet racks.

c. Users need 4 or 5 large 4’ x 8’ metal tables on rollers to break out kits.

d. Users need 4’ wide dutch door and OH coiling door to the hangar.

e. Users would like a window to the hangar from the administrative space.

f. Storage to be arranged with one main aisle and several smaller aisles with three shelves high -see image

g. See image from Dustin below.

ACTION ITEMS

1. Dustin to verify if 8’ or 10’ wide OH coiling door is preferred at FOM storage. 10’ can be accommodated with current design.

2. Coordinate large storage items with structural slab.

3. Coordinate shelving height from top of shelves to structure with FPE to ensure it doesn’t interfere with fire protection.

4. Coordinate larger door with structure from hazardous storage to tool crib. Currently, a structural brace would be conflicting with the wider door.
