Construction Security Plan (CSP) - Melissa Schlick to provide Construction Security Plan (CSP) that will cover the construction security requirements of the areas for our organization within the BACH. This was delivered on 6 September 2024. Please let us know if there are any questions.

Trash Enclosure – South side of building? Base CE to provide possible locations. Matt DeToy will discuss the trash removal process with the contractor, ongoing.

Interior Design: Waiting on for the Room Data Sheets: Requesting follow up information from meeting on 07-24 about Tool Crib equipment and storage needs, and Hazmat storage and equipment needs from Dustin. Looking for type and quantity needed. Dustin Baker is working on an updated version of the equipment list for the Tool Crib, ongoing.

Electrical: Waiting for word from Rafael via the chain of communications regarding exactly how future electrification capacity/space/etc. may or may not be incorporated into the building’s interior electrical distribution system design. Rafael confirmed the design intent, and the design team is prepared to move forward.

Miscellaneous Items:

The design team has provided a BACH Fire Hydrant Plan. It was discussed that a low-profile hydrant is not permitted per the UFC. Additional discussions will take place at our next meeting. Below are questions from BCE.

1) What are the line sizes for the water lines and fire water lines?

2) Two fire pump rooms in the Hangar with one on north and south sides based on two firewater connections OR they using existing fire pump bldg. on the west side of Douglas as well as the fire water tanks?

3) Do we need the future campus Fire pump bldg. and fire water tanks for the B-21 campus now that

HEF is not required in the hangars? Question for Cahill maybe?

4) PIV locations for Firewater lines?

5) Fire hydrants not blocking any hangar access doors?

6) FH in the southwest corner is a dead leg, how long is this dead leg line?

7) Why not complete the loop on the west side of the Hangar? Paint hangar to the south will have a loop water around it on the north, west, and south sides.

8) Pressure/flow test data of existing lines being connected to on the south and west for domestic water and firewater?

Please have the DFPE confirm that the base power utility is considered reliable power regarding the use of electric motor-driven fire pumps. (UFC 3-600-01 §1-12.7.2).

OG&E will construct a new 40MVA substation with generator backup north of the BACH site and dedicated to TAFB . From the south of the BACH site OG&E will tie into an existing TAFB dedicated service sourced from OG&E substation 5 which is internal to TAFB. These two actions will satisfy the UFC requirements.

Civil-Site

0013 – CRITICAL PATH

Need confirmation on security requirements for construction (access, fencing, monitoring, etc).

After getting clarification on the request, the safest option is to fence off the construction area so that security and access for the existing compound is maintained, but construction crews can access the site via their own gate that they secure when not in use. Essentially a freezone like currently being used at Lancer gate (construction crews have no access to the current compound they don’t need access to, but can easily access the construction site). I’m not familiar with security requirements for ongoing construction projects, but I assume at least a chain-link fence with barbed wire outrigger that’s secured at night/when not in use and an “authorized personnel only” type sign.

Subject: [Non-DoD Source] RE: TAFB BACH - WWYK263009 - RFI No. 16 - Confirm requirements for impacting the floodplain.

Chad, Below are the answers I received from CSU-CEMML management regarding a contractor being required to update the floodplain data after construction altered the landscape. Basically, there are no requirements in place for the CSU-CEMML enhanced floodplain data or the FEMA data. For the CSU data they do suggest reaching out to our floodplain sponsor for a “re-do” of the data. For FEMA floodplain data, there is no requirement, but if there is a benefit to the base, a LOMR or LOMA can be submitted.

I am not aware of any requirement to do this, and certainly not from our project or the CSU side of things. For a base to require a contractor to provide updated “post construction” flood data, I would imagine it would have to be in their contract to do so (with requirements for who is qualified for doing so). If you received such data, you could add that in as a separate feature to your Inundation feature class, but I would not recommend trying to alter the CSU Eng provided data (or FEMA for that matter).

In terms of the CSU flood data:

It would be assumed to be accurate as of the modeled date.

…Or in reality the date the LiDAR data that was used in the model was flown.

If a large area was affected, my suggestion would be for the PM to reach out to our sponsor (currently Heather Hatlestad) and request that we add the base back to our flood plain list for a priority “re-do” based upon significant constructions changes.
