Amendment No. 0003

14A. The following questions were received. The questions and the government’s response to those questions are hereby incorporated into the solicitation and any resulting contract.

QUESTION AND ANSWERS.

QUESTION 1: Specification Para 3.1.4 Hot Work

Are there any guide lines for work schedule (hours per day) start/stop times?

ANSWER 1: Work hours 7:30 AM to 5:00 PM Monday through Friday. Contractor may coordinate any work outside of these times with the Engineering Officer. Any work performed outside of the specified hours will not be grounds for reimbursement by the government.

QUESTION 2: Specification Para. 1.15 Access Plan

Does the plan need to be approved prior to starting performance?

ANSWER 2: Access Plan shall be submitted at the Arrival Conference for review and acceptance.

QUESTION 3: Specification Para. 3.1.19 Tank Work

If tanks need to be pumped does this mean the contractor needs to supply a temporary potable tank?

ANSWER 3: No, the ship will have potable water shore.

QUESTION 4: Specification Para 3.7.6 Thru 3.7.11 what is GFE equipment (if any) in these paragraphs?

ANSWER 4: Government Furnished Property is defined in Specification para .13 as “TYPE I, II, III Reefer Condensing Units, TYPE I, II, III Coolers, TYPE I Modular Walk In Refrigerated Boxes. Contractor shall provide all other necessary material s and equipment necessary to perform the install.

QUESTION 5: Specification Para 3.7.13

3.7.13 Gauges Thermometers, test connections

Are any of these GFM MATERIALS?

ANSWER 5: No, these materials are considered installation material and contractor should include these items in their proposal.

Solicitation No. HSCG40-09-R-50039

Amendment No. 0003

QUESTION 6: Specification Para 3.10.1 Surface preparation

The areas that get thickness measurements (should be completed) prior to coating D.) could not get access to inspect shelving during ship check

ANSWER 6: The thickness readings shall be completed prior to recoating the tank top.

QUESTION 7: Specification Para 3.10.2.1 Lead based paint

Calls for test 7 days prior to the performance (how can this be accomplished without removing the box)

For remediation if lead paint is discovered: please provide a square footage figure for worst case scenario; or may this be treated as growth work?

ANSWER 7: A small section of the sheathing and insulation can be removed for testing. A specific location for each sample has not been identified and wil be responsibility of the lead remediation contractor. However, the samples shall not be closely adjacent to any other sample location. The estimated area of remediation is approximately 3500 ft2, but it will be the lead remediation contractor’s responsibility to determine the full area.

QUESTION 8: Specification Para 3.13.2 Crane service

Can we bring in our own crane truck? Or are we required to use the CIS contracted cranes that are used by the government at each of the locations (Alameda and Seattle)?

ANSWER 8: The contractor is responsible for providing their own crane and rigging services for installations at homeports; however, installations at the Coast Guard Yard will be handled by the Coast Guard Yard personnel. Contractor will be required to provide a credit in contract line item 0007, 0019, 1007 and 1022 for these services perform at the Coast Guard Yard.

QUESTION 9: Specification Para 3.13.3 Temp. Boxes

Does the contractor need to supply the power source (or will it come from the ship)

ANSWER 9: The government will provide electrical power for temporary boxes. The contractor will need to provide notification of the required power at the time when they are provided a task order.

Solicitation No. HSCG40-09-R-50039

Amendment No. 0003

QUESTION 10: 3.13.12 Testing

When can we expect to receive the test plan for the 378 “W” Cutter

ANSWER 10: Test Plan will be furnished within two (2) weeks after contract award.

QUESTION 11: Do you have a consolidated list that lists all GFE or GFM? It would be nice to have a list of all parts and equipment that is supplied by the government that includes manufacturer and model #. This info is needed especially for the PLC. The spec requires for us to write the software, install software and firmware, and supply the ship with cables for the PLC. Without manufacturer or model # of the PLC it is hard to know exactly how to quote this portion of the spec.

ANSWER 11: The list of GFE/GFM was provided in the specification. The manufacturer for the PLC is Automation Direct for 210’ 270’ and 378’ Coast Guard vessels.

QUESTION 12: Also, in regards to the relief overboard piping: can we tie into the existing overboard piping or do we have to run new piping with through hull penetrations? Our ship check of the Cutter in Alameda showed that the existing piping was used as a tie in.

ANSWER 12: The relief overboard piping can be incorporated into the existing overboard piping provided that it is correctly sized to handle the required discharge rate, which will be contractor’s responsibility to determine. If the piping is not correctly signed the contractor shall be required to replace the overboard piping in accordance with 3.7.16 of the specification.

!4B. Physically remove existing specification and replace with the attached REV B dated 9/16/09.

Date and Time for receipt of proposals remains September 22, 2009 at 2:00 p.m.

All other terms and conditions remain unchanged.
