Amendment 0002

1. RFI: What is the preferred coating/painting specification?

RESPONSE: No coating is required

2. RFI: The dimensions are on the drawing but as for tolerances for these parts we don’t see any. What are they if any?

RESPONSE: No tolerances are provided. Fabrication should follow the drawing requirements.

3. RFI: Are we allowed any twisting from normal welding processes?

RESPONSE: No twisting will be allowed during the fabrication process.

4. RFI: The 85’ driver. Is this to be shipped as one piece or can it be in sections? If in sections, what length can we ship? Such as a 60’ and 25’ sections or other combos?

RESPONSE: Reference Amendment 0002 to the request for quote. See paragraph 2 under the heading Specifications in the attached Scope of Work dated March 04, 2016. The anchor length required is sixty (60) feet. See also the corrected drawing S-4 for further detail.

5. RFI: Can a different steel be substituted such as ER70 S6 and welding with 95% argon/ 5% CO2?

RESPONSE: No steel substitutions will be accepted. Comply with the specifications in the Scope of Work and on the drawings. Anchors and Drivers shall be fabricated using A573 Grade 50 steel. Comply with the welding requirements on revised drawings S-3 and S-4.

6. RFI: Drawing S-4 says “for reference only”. Will you document to use this as to what we are quoting?

RESPONSE: Reference revised drawing S-4. The “for reference only” has been removed, and additional information has been added to the drawing to clarify details.

7. RFI: Are there any models, other drawings, actual parts, or tech doc’s of these components? And can we have access to see them?

RESPONSE: The drawings attached to Amendment 0002 are the only drawings. For visual clarity, reference the photographs uploaded as part of Amendment 0002. Additionally, actual anchors and drivers can be seen at USACE Brazos River Floodgates, 4335 E Floodgate Rd Freeport, TX 77541

8. RFI: There are no fabrication specifications. Can you provide?

RESPONSE: The drawings include the fabrication specification information. Both S-3 and S-4 have been replaced as part of this amendment.

9. RFI: For the 4 drivers, the RFQ calls out for them to be 85 feet in length. Do these need to be one continuous length with no splice? If a slice is acceptable, is a splice specification available?

RESPONSE: The length required for the drivers is sixty (60) feet. See the revised Scope of Work and reference the clouded note on revised drawing S-4. Welding requirements are shown on the drawings.

10. RFI: Could you please clarify item 10 on the attached drawing? The material does not match the part.

RESPONSE: Reference the revised drawing S-3.

11. RFI: We haven’t found any finish and marking requirements? Are there any and if so, what are they? (Duplicated, see Q&A 1)

RESPONSE: There are no coating or marking requirements

12. RFI: Drawing S-4 NOTES: ALL STRUCTURAL STEEL SHALL CONFORM TO ASTM SPECIFICATION A36. However, the solicitation on page 4 specifications; 110 each Mud Anchors shall be fabricated as per attached drawings and specifications from A572 Grade 50 steel

Which steel specification do you require and which pieces do you consider structural steel?

RESPONSE: Drawing S-4 depicts the anchor follower (driver) while drawing S-3 depicts the anchors. The drivers are specified at ASTM A36, while the anchors are ASTM A572 Grade 50.

13. RFI: Delivery Dates. Are you flexible in this time line?

RESPONSE: No.

14. RFI: Drawing S-3, item number 4, part number 91-39-IF-4 and number 5, part number 91-39-IF-5. We need to know what size hole required. Drawing S-3 Item number 10, part number 91-39-IF-10. Is this tube and if so you have a better drawing section of this?

RESPONSE: - Please see attached drawing with revisions.
