SUMMARY OF CHANGES

SECTION SF 1449 - CONTINUATION SHEET

The following have been modified:

QUESTIONS & ANSWERS

Q & A Section Q: Is the delivery date really 7/17/2017?

A: The delivery date has been changed with Amendment 0001. Delivery is now due on or before 7 weeks after date of contract (7 wks ADC).

Q: The drawings are labeled “1 of 3” and “2 of 3.” There is no third page.

A: Page 3 of the drawings contains specifications for another item (spud pins) being fabricated separately from this contract. It is not relevant to this solicitation.

Q: The Welding Notes section of the fabrication drawings indicate the welding is to be SMAW (Shielded Metal Arc Welding – aka Stick welding), by specifying the electrode type to be used.

Is it permissible to use SAW (Submerged Arc Welding) and/or FCAW (Flux Core Arc Welding) instead?

A: The drawing did not require the use of SMAW welds. The weld electrodes as shown were provided for guidance for weld metal tensile strength requirements. Any welding process can be used as long as: (1) weld metal tensile strength agrees with electrode as defined on the contract drawings;(2) welding process does not compromise base metal strength.

Q: We will have prequalified ASME Sec IX weld procedures and welder qualifications. The drawing states AWS D1.1 code. I assume ASME would be more than sufficient.

A: Use of ASME Section IX for welder's qualifications and welding procedures is not acceptable since ASME does not address the structural materials, as used in this contract.

Q: The drawings show four different shell [spud body] sections, ranging from 10’ 3” to 12’ in length. Our normal suppliers are only able to furnish the plate in 8’ wide sheets at the thickness required. In addition, our standard shop equipment can handle plates up to 8’ wide. We’d like to build the shell in four sections, each 8’ or shorter in length. This would require additional weld seams. Is this acceptable?

A: Use of 8-foot wide section to construct spud body above tip assembly is not acceptable. The structural design includes transverse plates in way of the weld seams to provide adequate strength and assist with plate rolling/forming tolerances. If 8-foot wide plate sections are used, additional transverse plates would be required. The additional transverse plates will increase spud weight above current spud design weight, which is not acceptable as spud weight is limited by lifting capabilities of existing spud winch. ASTM A514 Gr. B plate widths up to 120 inches and plate lengths up to 480 inches, are available. Further, it should be noted that since the contract drawing permits only one longitudinal seam in the spud assembly, the required circumference of each rolled plate segment requires a minimum plate dimension of 113" prior to rolling, for each spud segment. Therefore, plate dimensions that are greater than 8'-0" are required for both plate width and length, for each spud rolled plate segment.

Q: Our shop only has the capability of rolling 10’ wide plates of the thickness required. May we deviate from the drawings?

A: No. See previous answer for an explanation.

Q: My shop regularly does hard surface welding for similar sized pieces. Would you like us to provide an estimate for that additional work?

A: No. As stated in the solicitation, Government labor will be used to complete the hard surface welding.

Q: Will there be NDT (non-destructive testing) required on the welds?

A: No testing is required.

Q: In the fabrication drawings, Section 11-E, can welds be made on the outside only?

A: Welding shall be completed on the inside as required.

Q: In detail drawing 14-C, they are asking to back the weld on the inside. This cannot be done with the baffles welded in the ends. How would they like this weld made?

A: The back welding would have to be completed prior to the baffle plates being installed.

Q: According to my plate rolling company [subcontractor], [to form the main spud tube] the plate would have to be rolled in two halves, as A514 will spring back; or the plate may be hot rolled. Would it be possible to roll in halves?

A: No. The additional seam could weaken the spud.

Q: In the Statement of Work, the solicitation states that “Unloading assistance will be provided by the Government.” However, on page 5, Item No. 0001, it states that “Contractor shall be responsible for unloading at destination.” Which is correct?

A: Government labor and equipment will be used to off-load the spuds when delivered.

Q: The fabrication drawings are calling for Item 9, two pieces of 4" pipe, each 14-3/4" long, welded at the center, and the weld splinted with an 8" piece of 5" pipe. It would make more sense to use a solid piece of 4" pipe, 29 1/2" long.

A: A solid piece of 4” pipe 29 ½” cannot be used. The two 14 ¾” lengths of pipe are not butt welded in the center. The 8” long 5” diameter pipe welded over the 4”pipe allows for slight flexing when lifting the spuds.

Q: In the fabrication drawings, Item 8 calls for 3" thick plate. As we were reading the drawings (Section A-A and Section C-C), the 3 inch plate is being welded with an inch sticking out beyond the OD of the pipe, then machined off. That seems like a lot of grinding without an obvious purpose. Could we use a thinner piece of plate, and have it recessed to the outside diameter of the main pipe?

A: The 3” thick plate is required. Refer to Detail 15-E on page two. The 3” plate can be machined prior to inserting in to Spud.

Additional Questions & Answers Added By Amendment 0002 – 25 May 2017 Q: The second question of the Q&A section says Sheet 3 is for spud pins being fabricated separately from this contract. Does that mean items 15 and 16, called out as spud pins on Sheet 1 of 3 are not required as part of this quote?

A: The Spud Pins are not part of this contract. Please do not include them in your quote.

Q: Item 13 has a Quantity of 6 pieces. Should this be 12?

A: Yes, 12 pieces is correct. The drawing should be corrected to show 12 pieces. [A revised drawing is expected to be released Tuesday, May 30 and will be provided via a separate amendment]

Q: Item 13 calls for ½” thick material on the Bill of Materials. Detail 13-E shows the material as ¾” thick. Which is correct?

A: The ½” material for the Baffle Plates (Item 13) is the correct thickness. [A revised drawing with this change is expected to be released on Tuesday, May 30 and will be provided via a separate amendment.]

Q: The paint requirements per drawing 816-B406-01 call for yellow spud markings per clauses C406 and C460. Where do we find the information on what part(s) of the spud get painted yellow?

A: No Yellow paint is required. Spuds shall be painted BLACK per “Hull Exterior Below Waterline.” Refer to document 816-B406-01.

Q: I have to agree with the person regarding Q&A #10. The back side of the weld joint at detail 14-C cannot be made to the current design. It cannot be done before the baffle plates weld in either because then the baffle plates will not be welded as noted in detail 13-E. 13-E says the baffle welds need to face the spud wall seam. That will not be possible if the baffles are not welded in before the tube sections are welded together and it also defeats the purpose of the baffle plates being used to round the tube before the sections are joined together. Is it possible the note in 14-C is actually asking for a weld backing ring inside of the pipe?

A: Spud construction should be as follows, in accordance with contract drawings:

1. Roll plate sections to form pipe sections, with longitudinal weld seam, without baffle plates.

2. Weld transverse baffle plates to rolled pipe sections.

3. Weld rolled pipe assemblies containing transverse baffle plates together, to form spud.
