Sparks-san, I have a question about MT consideration for bow ramp prefabrication job.

Is the previous .38E9366211_A01 will be cancelled? If so, I will recreate job spec A02 as new one including necessity requirements of A0l. Please advise.

Dasan, I made the rounds with Engineering and Planning for questions 7 through 10 as discussed:

7. Recommend to fabricate per drawing 169-5110389 Rev. B, excluding installation of the pocket padeyes. KTR should fabricate them, but final welding to the bow ramp can be done by installing activity unable to template properly from craft at this time. For hinge pads on bow ramp, those have to be installed in drawing locations as the bow ramp longitudinals provide structural support to them. Instead, please prepare for relocation and possibly fabrication of new hinge padeyes on the craft side to match the bow ramp. Material has not been ordered for the craft side hinge pads yet, but that can be on the installation work spec.

8. MT and VT are the requirements and what will be covered by the work spec. However, you can notify the KTR that engineering will accept proposals for PT NDT locations in a CFR. We will approve for locations where MT equipment cannot fit into and have it documented .

9. Current work spec only covers construction primer. However, we prefer full preservation as the primer will have to be removed prior to final preservation. The geometry of the exterior of the bow ramp has a lot of pockets to go redo later. If fully preserved from beginning, then only have to redo the small locations where hot work is to be done. It's a preference so I'll leave it up to the Maintenance Team.

10. We're okay with the proposal along with the comments from 7 above.

Understand that a revision spec may be needed to incorporate these changes.

Please let us know if you need anything else.

Respectfully, Cary Fujikawa, Jr.

Kurita-san, We will work with on engineering department to provide a REV SPEC and amend the solicitation by 14AUG26.

Cary and Matsumoto-san, We are looking to fabricate as much of the BOW Ramp as we can with it still being attached to LCU-1651. Remainder of the fabrication, load test, and final installation will be done under a different job during the DSRA starting in FEB2027. Can you please provide answers to the questions attached? Additionally can you validate what is best to be done by the installing contractor to best fit the bow ramp on LCU-1651 during the DSRA?

Initial look for the Maintenance Team is that we would hold off on the hinges, striker plate, and the chain hoists attachment points.

Looking to get the REV SPEC done by 14AUG26. Standing by to discuss.

Hi again Sparks-san, I emailed KUBO immediately after receiving your last email. Their response is below.

"We are now entering the full -scale quotation preparation process.

If possible, we would appreciate it if you could grant us an extension until August 28 to submit our quotation.

Thank you for your understanding and consideration."

After I received the above email, I called KUBO to ask them to reconsider the August 28 deadline. This is because while the current IGE is SAT, there is a possibility it could exceed SAT. Given that it is the end of the fiscal year, I am asking if they can submit the proposal a bit earlier. Based on our phone conversation, it seems unlikely we will get their response today.

Although we will close the RFQ tomorrow at 10:00am as planned, I expect it will result in a No Bid. Therefore, I plan to reopen it as soon as we hear back from KUBO. They also expressed some concerns regarding the spec dates.

I will let you know about that as soon as I receive their response anyway.

This is a quick update for now.

Thank you.

v/r, Hiromi Kurita

Kurita-san, We will accept the 4 month additional POP that is required for them to do the work.

Additionally, we will accept them fabricating in accordance with the DWG or

SRF Design Guidance.

Finally the painting requirements are listed in the DWG and the NAVSEA Standard Item table and we can clarify the requirement post award via CFR submission.

Please relay these responses to them so that we can proceed with receiving their proposal and follow on award.

Thank you.

Good afternoon Ms. Tanya, Understood. While it is a bit unexpected, I will keep the solicitation open as directed.

Regarding KUBO's requirements, please note the following critical points.

- Period of Performance: A 4-month PoP is required, with the earliest estimated start date being this November/December.

- Critical Requirement for Bidding: The most vital condition is that either SRF provides accurate drawings, or the bow ramp must be removed for measurement. Without meeting one of these options, it will be extremely difficult for KUBO to bid.

I will stand by.

Good morning Ms. T, Thank you for the answers.

I will forward them to Kubo, and issue the amendment once I receive all of the answers.

Please provide me the answers to #3 and #6 by noon, August 6 so that the amendment will be issued before the original closing date, August 7.

Separate note:

Below is from SHI.

"Regarding the bow ramp, 100% NDT is required for the welding. This means we must repeatedly perform QA-witnessed NDT after each welding session, which significantly slows down the work speed and requires a large amount of labor.

If we focus on other LCU tasks, we cannot allocate enough hands to the bow ramp, leaving us with no choice but to secure a separate team. However, the welding work requires certifies personnel, and it is currently very difficult to gather enough qualified workers. The reality is that we do not have enough certified welders to handle both the main LCU construction and the bow ramp at the same location.

Furthermore, regarding the location, there are very few sites in Sasebo that are close to the sea and suitable for loading onto a barge. SSK is technically the best location for this."

Thank you.
