ANSWERS AND CLARIFICATION

ANSWERS AND CLARIFICATION

Answers and Clarification

1. Q: What is the reason for the re‐solicitation?

A: There are several reasons why the original solicitation (no. N00167‐17‐T‐0019) was canceled and re‐released as the present solicitation, including that the original solicitation did not adequately define the Government's minimum requirements.

2. Q: Please confirm that “Any quote that does not meet each of the specifications listed in Table 5 will be deemed technically unacceptable and unacceptable for award” also includes lead time, delivery date of August 11, 2017.

A: Yes, a quote that does not offer a delivery date of August 11, 2017 (or earlier) will be considered technically unacceptable.

3. Q: Please confirm that this solicitation is a 100% Small Business Set‐aside.

A: Confirmed that this solicitation is a 100% Small Business Set‐aside. Only quotes received from offerors that are small businesses under the applicable NAICS code (333923; size standard 1,250 employees) will be evaluated and considered for award.

4. Q: Do the questions and answers from the prior solicitations still apply?

A: The questions and answers from the prior solicitation do not apply as this is a new solicitation.

5. Q: When is quote due?

A: The quote is due 3/13/2017 by 4:00 PM EST.

6. Q: What ambient temperatures can we expect during start‐up and operations?

A: Operation in a marine environment in Ketchikan, Alaska includes expected ambient temperatures ranging from ‐5° to 30° C during start‐up and operations.

7. Q: The anchor winch will be extremely wide due to storage capacity and layer limitations.

(a) Can it be fabricated where as it can be broken down for transport and lift, such as the power unit being separated from winch for transport?

(b) Can it be totally separate with quick connects at hosing and electrical feeds.

A: (a) Yes, an anchor winch that is fabricated to allow the unit to be broken down for transportation and lifting, with a power unit that may be separated from the winch for transport is acceptable, provided that all pieces can be mounted on a single foundation for lifting, handling and installation, and that the final assembly meets all of the requirements in RFQ Section B, paragraph 2.1 [now paragraph 3.1]. During shipment, the assembly can be broken down as long as it will be re-assembled on a single consolidated foundation.

(b) Yes, the anchor winch may be totally separate with quick connects at hosing and electrical feeds, so long as the final assembly meets all of the requirements in RFQ Section B, paragraph 3.1.

8. Q: The positioning winch spec mentions constant tension and tension limiting by the operator. Are these the same functionality? Or as defined below?

A) Static tension whereas the operator only limits what the winch can pull with a knob.

In this case the operator would have total control over line speed with a joystick and a line tension cap provided through a knob. Over hauling would limited.

B) Is it a true dynamic constant tension whereas the load cell provides an input to the system and the system automatically hauls in and pays out the winch to maintain a desired rope tension? Under these circumstances in most cases the line speed would not be controlled by the operator. If the winch is below tension setting it would retrieve or payout line as fast as possible until the desired tension is achieved.

(a) If the answer is "B" a PLC control system could be required. Is this acceptable and if so is AC power available?

(b) What accuracy of constant line tension would be required?

A: (a) The answer is "B" above. A PLC control system is acceptable, provided that its operations are incorporated into the local winch control station (see RFQ Section A, paragraph 3.2.4). AC power will be available to provide power for electronics, but not to provide primary power to the winch (see RFQ Section A, paragraph 3.2.1). The Government can provide AC power to power the PLC control system, if the PLC control system requires a power source other than the positioning winch’s diesel engine.

(b) As noted in the RFQ (Section A, paragraph 3.2.4), the positioning winch’s controls shall allow for the winch to be configured to maintain a constant line tension at an operator-adjusted tension setting. For the control station’s constant line tension reading, accuracy of plus or minus 10% (or better) of the displayed reading is required.

9. Q: Regarding the level wind being capable of spooling two rope sizes. Is changing a sprocket an acceptable means to meet this requirement or would a drive ratio that falls between the two sizes acceptable?

A: Yes, changing a sprocket is an acceptable means to meet this requirement.

10. Q: For the position winches, maximum speeds for pay in and pay out are 100 and 300 ft/min respectively. Can we assume that the higher speed payout is for line handling and not to be performed under full load? This will significantly reduce the cost and size of the system.

A: Yes, offerors may assume that the higher speed payout is for line handling and not to be performed under full load.

11. Q: Similarly for the anchor winch can you confirm whether the 100 ft/min speed is required at maximum linepull? Typically for class standards (Lloyd's, abs, DnV) 30 ft/min is required at full load. We could offer a dual speed winch with 100 ft/min at reduced load if that is acceptable.

A: The 100 ft/min is not required at full load but is expected at about 50% load.

12. Q: Is the intent to have separate diesel power units for each winch, 4 total?

A:Yes, each winch will have its own diesel power unit.

13. Q: The current amendment # 2 and also # 1 are using the same line number for description of the specifications. For example, positioning winch power is 3.2.1 and anchor winch power is using the same numbering system (3.2.1) but has different specifications. Should this be numbered differently?

A: The paragraph numbering reflected in the previous amendment (Amendment 2) was correct. The specifications are divided into four sections (Sections A - D), and the paragraph numbering begins anew in each Section. Therefore, in the example provided, positioning winch power requirements are specified in Section A, paragraph 3.2.1, while anchor winch power requirements are specified in Section B, paragraph 3.2.1. Table 5, in Section D, follows this Section and Paragraph numbering paradigm as well, and the Section (A, B, or C) is indicated above the "Specification Section" heading for each Section in Table 5.

Please note that there was an error in Table 5 as it appeared in Amendment 2, in that the Section C specifications are repeated in Table 5. This error is corrected by this amendment (Amendment 3).

14. Q: Please confirm the only requirement for this solicitation to be classified as a small business is to have less than 1250 employees.

A: The Government cannot confirm as stated. For the purposes of this solicitation, an offeror must meet all of the applicable U.S. Small Business Administration (SBA) requirements for a small business concern (under NAICS code 333923, the NAICS code applicable to this procurement), as set forth in the SBA's regulations at 13 C.F.R. Part 121.

15. Q: If we are a Canadian based company are we eligible to bid for this contract?

A: The Government will not advise individual offerors or concerns as to their eligibility to bid for this contract. The Government does note, however, that it is unaware of any authority that would restrict an entity's elibigibility for an award for this specific solicitation based solely on the fact that the entity is based in Canada.

Additionally, the Government hereby notifies potential offerors of the percentages that may be invoiced for each CLIN:

CLINs 0001 and 0002 shall be no more than 5% each of the total value of the contract.

CLINs 0003 and 0004 shall be no more than 10% each of the total value of the contract.

CLINs 0005, 0006, and 0007 shall be priced as necessary.

The RFQ has been revised to correct errors in the Section/Paragraph numbering. The RFQ has also been revised to remove the duplicated rows of Section C listed in Table 5.

The Government has received a comment regarding difficulty opening solicitation documents.

Any potential offeror that this unable to open any document uploaded to FBO for this solicitation may contact shelby.o’neill@navy.mil for copies of solicitation documents. No additional time will be provided to respond.
