Questions and Answers

1. Will past performance on non- federal government contracts related to rail car design, testing and manufacture be acceptable and desired (state, local government and commercial)?

Answer: Yes.

2. How does the Government intend to evaluate delivery pricing under the Solicitation's Item 0006 and SOW Section 3.4.5?

Answer: The cost of the shipping should be considered for all 3 Strategic Weapons Facility locations. The exact location will be determined by available location prior to the delivery order. The Government will evaluate comparatively with respect to shipping location.

3. When the railcar is delivered, is it the Governments expectation the car will be a fully commissioned car and able to be towed or the car will not be fully commissioned, and transportation must occur using a method other than towing?

Answer: Fully commissioned and approved for use on rail with AAR.

4. Were any risk reduction contracts awarded prior to this effort? If so, can you provide the contract number and what data rights the Government owns?

Answer: No risk reduction contracts have been awarded prior to this effort.

5. For each order, will there be a Not-to-Exceed amount given for Shipping since shipping costs may vary? Who bears the risk or the rail carrier damage?

Answers: Shipping should be planned out by the vendor. Assumption of risk is in accordance with "Freight on Board" (FOB) terms.

6. Is there an incumbent for this requirement?

Answer: No.

7. What are the number of rail cars to be manufactured for development and production?

Answer: See Section B.

8. What is the minimum quantity for this IDIQ?

Answer: See Section B

9. What are the number of flat railcars for this contract?

Answer: See Section B.

10. After contract award, how long will it take the Technical Point of Contract to provide GFI.

Answer: 30 days.

11. What should be included in the Bill of Material (BOM)?

Answer: The BOM should be based on the final design of the railcar.

12. Is the end of railcar hydraulic cushioning required?

Answer: Yes. Defined in the Systems Requirement Document (SRD).

13. Please confirm that the design of the NSWC AIM Flatcar should be to AAR-M1001 Section C, part II, and not to any standards pertaining to tank cars.

Answer: Yes. Defined in the Systems Requirement Document (SRD).

14. Are there drawings for WS20972?

Answer: See the new GFI issued with current Solicitation Amendment.

15. What is the G-loading in conjunction with the requirement of the lightweight car of 116,000 pounds?

Answer: Please review Section 3.39 Figure 11 in SRD and the interface drawing Trident II AIM Flatcar /SSE Interface Dwg. 5681514.

16. On page 19 Section 3.12 of the SRD, correct?

Answer: Yes. Please review Section 3.39 Figure 11 in SRD and the interface drawing Trident II AIM Flatcar /SSE Interface Dwg. 5681514.

17. Will WS20972 be provided?

Answer: See the new GFI issued with current Solicitation Amendment.

18. Will the AIM Railcar Bulkhead, AIM Shipping Fixture, and Loading Tube as shown in the 'D5 AIM FLATCAR CARGO' figure of drawing 5681514 be provided as GFP for testing? Additionally, will all the hardware to attach the cargo structures to the flatcar be provided for testing?

Answer: Please review the GFP.

19. Is the government providing mechanical and fabrication drawings for the shipping fixture, bulkhead, and loading tube?

Current drawings provided do not have enough details to create CAD for analysis.

Answer: Please review the GFP.

20. What are the timelines for CLIN 0001 and CLIN 0002?

Answer: This can be negotiated.

21. What are the design criteria for the G forces/ strike-down load listed? Are they yield or ultimate?

Answer: This is listed in Trident II AIM Flatcar/SSE Interface Dwg. 5681514 in Figure 11 in the SRD.

Answer: Strike download did change but is listed in the updated SRD. Strike down load updated to 355 kips.

22. Is the 116,000 pounds lightweight critical given the Vertical G force requirement or is the overall capacity the critical element?

Answer: This is listed in Trident II AIM Flatcar/SSE Interface Dwg. 5681514 in Figure 11 in the SRD.

23. What is the maximum allowable length of the railcar?

Answer: Defined in the Systems Requirement Document (SRD).

24. Should max width of rail car fit within plate C? 10'-0" Recommended for max width with deck length of 68'.

Answer: Defined in Systems Requirement Document (SRD).

25. What is the preferred length of the rail car deck?

Answer: Defined in the Systems Requirement Document

26. What is to be done if the wheels, axles, bearings, side frames, truck bolsters, or span bolsters don't meet the G-loading criteria?

Answer: The system fails and redesign will be required.

27. What is the anticipated date of contract award?

Answer: The anticipated award date will be No Later Than 5 Mar 2027.

28. The empty weight of the car, resulting from the Gross Load Weight/Gross Rail Load requirement stated in Section 3.3.1, is not achievable.

Answer: The GRL is 286,000 lbs. The main focus is configuration 4.4. This will be the transportation load weight with the AIM that will be transported from site to site. Configuration 4.4 is listed at 186,800 lbs., therefore leaving 99,200 lbs. for the weight of JUST the flatcar to meet the 286,000 lb. GRL.

29. The Navy has requested a 68-foot car, the empty weight of the flatcar would be heavier than 80,000 lbs., thus resulting in an excess weight.

Answer: Configuration 4.1 thru 4.4 is the only transportation requirements so the max configuration load is 186,800 lbs. This leaves 99,200 lbs for the weight of JUST the flatcar. Regardless of this, if the design that the vendor creates is over that limit they will need to work with the railroad to put waivers in place so that the flatcar can still travel over the rail limiting the 286,000 lb gross load weight. Additionally, there are some specialized, higher-capacity cars that can handle a Gross Load Weight of 315,000 lbs, though their use might be restricted to specific routes capable of supporting such heavy loads.

30. In Drawing 5681514 on page 60 of 97 of the file "Drawings and SRD.pdf", Note 17 says that "Truck Axle Loads shall not exceed 60,000 lb. per axle in any load condition." To meet the axle load requirement, more than 4 axles are necessary.

Answer: The design DOESN'T have to be a 4-axle flatcar.

Answer: Question and answer above are no longer applicable because it is an obsolete facility requirement.

31.A 6-axle railcar cannot be designed due to the elimination of 3-axle truck bolsters by the rail industry. If the design changes to an 8-axle car, which uses commonly available components, the design of the railcar must be altered resulting in a change in the length specification, a change to the deck height and increase in weight of the railcar which will all exceed the current specifications.

Answer: This is defined in the SRD. This needs to meet the HxWxL requirements.

32.WS20972 and MIL-SPC-810. The specification refers to the securement of the load, but doesn't specifically say the equipment used to transport the load must be designed to these criteria. Please confirm the loadings specified in WS20972 document and MIL-SPC-810 apply to the securement of the load and not the vehicle itself.

Answer: Yes the loadings specified that WS20972 and MIL-SPC-810 apply to the securement of the load.

33. The SRD-500778 includes Configuration 5 requiring support of 249,500 lbs of cargo load, with Configurations 6 and 7 requiring 224,800 lbs. and 230,100 lbs. respectively. If the intended railcar design basis is a 286,000 lb. gross rail load platform, Configuration 5 would leave only 36,500 lbs. available for the car tare weight, which does not appear feasible for a compliant flatcar design. Also requesting Clarification regarding whether the new AIM Flatcar is intended to be limited to a 286,000 lb. gross rail load design, or Configurations 5, 6, and 7 load cases are to be interpreted differently than standard railcar cargo load/gross rail assumption.

Answer: If the design calls out for a higher GRL than 286,000 lbs. waivers can be discussed and that discussion can start. For more details, see previous comments about the load configurations. Configuration 4.4 is the main concern for the transportation load. 4.5 - 4.7 are used for storage and operational use at the facility.

34. At this time, the 286,000 lb. capacity requirement does not appear to be explicitly stated in the SOW text itself, 34.

Answer: Please see note 18 on Drawing 5681514. "ONLY LOAD CONFIGURATIONS 4.1 THRU 4.4 ARE USED FOR

TRANSPORTATION. OTHER LOADS ARE USED FOR STORAGE AND OPERATIONAL USE AT THE

FACILITY". Configuration 4.5 - 4.7 is just facility and storage requirements that will NOT leave the facility. They need to focus on configuration 4.4 as that is the main transportation weight for the cargo as it is in transit. In Configuration 4.4 the load is 216,800 lbs. With the max GRL at 186,000 lbs. this allows 99,200 lbs. for the weight of the flatcar itself.

35. Does the Government anticipate a heavier-duty design basis beyond a standard 286,000 lb. freight car platform?

Answer: The GRL is not listed in the SOW because it is a requirement and it is in the Systems Requirement Document

(SRD-500778).
