Question 1: WORK ITEM 6: Rub Rail, Remove, Inspect and Install

3.4 Reinstallation. After the completion of all inspections and any authorized repairs, the Contractor shall re-install each rub rail section, using new nylon insert locking nuts.

3.6 Paint schedule. For vessel 47206 and subsequent, area covered by fendering system and aluminum faying surfaces (surfaces of similar or dissimilar materials that are fit closely together and fastened) shall be painted in accordance with CG Drawing 47B-MLB 631-020.

Question: There is no scope of work about installing the rub rails as shown on BP#47B MLB 611-020

Rev H sheet 3 of 3 items 8 & 9. Wanted to check to see if we are still sandblasting the hull surfaces not mechanically cleaning them, inspecting them, applying two coats of the epoxy paint, applying a full coat of 5200 sealant on the hull surface then utilizing the 4200 sealant to seal up the seams and edges?

APM ANSWER: Yes the spec is somewhat vague on the work required. Based on paragraph

3.3.1(Clean & Inspect), the rub rail, fender mounting surfaces, etc shall be inspected and a

CIR submitted with results of inspection and any recommended repairs. The coating system is not to be applied/renewed until a CIR is submitted and a CR approved. A full coating of 5200 and 4200 on the seams will be applied upon re-installing the rub rails.

Question: I have looked through the drawing and 3360 Manufactures Instruction Book and could not find information on the Wiper speed pots, Do you have any other information on the wiper speed pots and if the wiper controllers are GFE why are not these?

In paragraph 3.2.1 has to remove the compass already, is there something more in table one to add to it?

Question: Are these special OEM hoses still contractor supplied or GFE, and are all of the hose end fittings that are not reusable under the end fitting inspection to be put on a change request for renewal?

APM Response: Since there has been some mis-understanding on previous contracts. For this contract, submit a CR for any fittings that need to be renewed, all fittings that need to be renewed will inspected by PE/COR and agree with KTR recommendations. If fittings need to be renewed and they have been inspected by PE/COR funding will be provided but extension will not be granted because labor hours are within the scope of work.

APM Answer 2: Special OEM Hoses shall be supplied by the Contractor

Question 5: WORK ITEM 24: Sea Strainers - Sea Strainers - Duplex (All Sizes), Overhaul

3.3 Reinstall. After completion and acceptance by the Coast Guard Inspector; the Contractor shall reinstall all overhauled, cleaned and new strainers to their original locations, as shown on Coast Guard Drawing

47B-MLB 505-020 and TP 3359. Renew all gaskets with material conforming to ASTM D1330 of the same size and configuration as those gaskets removed. Renew all hardware with nickel-copper alloy fasteners.

Question: Are we to renew fasteners with in-kind materials, not nickel-copper alloy?

APM ANSWER: YES in kind

Question 6: WORK ITEM 24: Sea Strainers - Sea Strainers - Duplex (All Sizes), Overhaul

3.6 Contractor’s option for strainer renewal. The Contractor may opt to renew strainers designated for overhaul if preferable for the Contractor, and is at no additional cost to the Government. New strainers shall be equivalent (including identical material) to the strainer being renewed. Visually inspect the piping and mounting arrangements, and submit a CFR detailing any required modifications to accommodate the new strainer(s).

Question: In the past, we have always had these strainers as GFE if they were not overhaulable, because, why would the contractor spend $6,000.00 on the new strainers when if the strainers were overhaulable, only costing about $1,000.00. Does not make fair bidding for the contractor to gamble they are in good condition, then if not, must purchase new ones.

Should be a change request if they not overhaulable, or will the GFE listed be available without contractor cost?

APM Answer: Yes PE/COR will request as GFE if they cannot be overhauled. Bid for Overhaul

Question 7: WORK ITEM 25: Sea Strainers - Simplex (All Sizes), Clean and Inspect

3.2.3 Reassemble. After completion and acceptance by the Coast Guard Inspector, reassemble all strainers.

Renew all hardware with nickel-copper alloy (Monel) fasteners.

APM ANSWER: YES in kind

ITEM DESCRIPTION LOCATION APPROXIMATE

SQFT.

Bilge Preservation needs to be

Completed underneath the Strainers in the Engine Room. Prepare and Preserve

IAW WI 38 TABLE 2

Engine Room APPX ( 8 sq ft)

Question: I believe this is just an error on location as in some of the previous bids since the location in table one is in the engine room which is already covered under WORK ITEM 23. Is the concerned area just in the

Aux Space as listed in the intent of work?

APM Answer: My intent is to preserve the bilge in the Aux as per WI 38. As for Table 1 and the intent to preserve the pocket under the strainers in the engine room. I need that preserved as well. IF that pocket is covered under WI 23 please disregard. DO not bid on preserving the pocket (under strainers) in the engine room twice. REV-01 will NOT be issued.
