1. Question: D-11 Shower Deck Drain Replacement, Paragraph 3.1, 3.3.3.4 - Table 3.1.A, Item #4 indicates that the Affected Head is the CPO WR, WC, SH (01-57-4-L) and that the Space Below Affected Head is space 1-65-2-L. The Affected Head, space 01-57-4-L, is located on the 01 Level, between frames 61 and 62, outboard of centerline on the Port side of the ship. A review of the GA drawings found that the Space Below Affected Head by this repair will not be space 1-65-2-L as indicated in the spec, but will in fact affect space 01-60-4-A (Freezer Storeroom) and potentially 01-60-2-A (Chill Storeroom) on the Main Deck. Contractor requests all drawings and tech pubs related to the freezer and chill storage areas.

Answer: We will be providing CD to Contractor for following Drawings and Tech Pub in electronic format:

2. Question: D-11 Shower Deck Drain Replacement – Paragraph 3.1.2 The scope of Item D-11 calls for the “replacement miscellaneous deck drains fittings serving shower stalls in thirteen (13) Crew’s Head and Government-furnished deck drain fittings.” Paragraph 3.1.1 states the “shall include, but not limited to, . . . Crew WR, WC, SH (01-88-1-L), . . .” Paragraph 3.4 states “install all necessary piping and fittings to install Government-furnished deck drain fittings in way of removed drain piping . . . . Crew WR, WC, SH (01-88-1-L) . . .” The list of thirteen (13) items under Table 3.1.A does not include Crew WR, WC, SH (1-88-1-L). Is it the intent of the USCG that the shower in space Crew WR, WC, SH (01-88-1-L) be included in the scope of work? If so, is there a space that is currently listed in Table 3.1.A that should be excluded?

Answer: The scope remains unchanged as thirteen (13) shower drains. Table 3.1.A has remained unchanged and is correct. Paragraph 3.1.1, 3.3, and 3.4 did have inconsistencies in describing affected heads and as a result changes have been made to those paragraphs. Please make the following corrections to the specifications for those three paragraphs:

3.1.1 The concerned work area shall include, but not limited to TABLE 3.1.A. CG Dwgs 225B-WLB 528-1 and 225B-WLB-644-1 are existing drawings that can be used to identify affected components and work areas.

3.3 SHOWER PAN (FLOOR) AND DECK DRAIN REMOVAL - Using the enclosed Figure, “Shower Pan and Deck Drain Piping Removal” as guidance, remove and discard components in the affected heads (TABLE 3.1.A) as described below . A crosshatched sections in the Figure denote components required for removal. Cut or grind welds for welded fittings, or unscrew threaded connections from components to facilitate removal. Mark all piping and components including deck drains for removal for verification by the Coast Guard Inspector prior to actual ripout. Discard all permanently removed piping and components.

3.4 SHOWER DECK DRAIN INSTALLATION AND DRAIN PIPING MODIFICATION – Using the enclosed Figure, “Shower Deck Drain and Deck Covering Installation” as guidance, provide and install all necessary piping and fittings to install Government-furnished deck drain fittings in way of the removed drain piping (deck penetration piping risers) in the affected heads (TABLE 3.1.A) as described below. Provide all necessary materials except the Government-furnished material (part #1 in Figure, “Shower Deck Drain and Deck Covering Installation”) to facilitate installation and modification. Horizontal piping runs shall have a minimum pitch of 1/8 inch per foot toward the direction of flow to achieve gravity drainage. Allow the Coast Guard Inspector to verify any proposed pipe runs prior to actual installation. Unless, otherwise specified in the specification, all materials shall be in accordance with Coast Guard Dwg 225B-WLB 528-001. For descriptive purposes piece number (P/N #) in parentheses are the same piece number called-out in enclosed Figure, “Shower Deck Drain and Deck Covering Installation.
