REQUEST FOR SPECIFICATION CLARIFICATION

NAME OF CONTRACTOR:

SPECIFICATION ITEM NO.:508

PARAGRAPH / SECTION NO:7.3.1 e.

TITLE: REPLACE ZONE 3 AFF PIPING REPLACEMENT, REV 1

QUESTION:

The paragraph identified above states to remove and replace with new 200 feet of 8” piping and directs you to reference 2.1.1 (NAVSEA Drawings #555-6241219 Foam

System Diagram) “page 6 plan view 22A”. There is no plan view 22A on sheet 6 nor on any other page or sheet of the provided drawing reference. Please clarify?

In addition, the enclosure provided that is identified as a list of contractor furnished material has no pipe or fitting listed that are 8”. Please clarify?

ANSWER:

Reference 2.1.1 is NAVSEA Drawing # 555-6241210 rev G ‘Foam System Diagram’ not

6241219. The Enclosure identifying CFM for Zone 3 mistakenly omitted the 8” pipe.

This material is to be bid as written in 7.3.1.e as CFM and is Seamless Carbon Steel, ASTM A-106, Grade B, Extra Heavy pipe.

Paragraph 7.3.1 e is in error & should read:

“Remove and replace with new 100 feet of 8” Zone 3 piping between frames 60 to approx. frame 54. See reference 2.1.1, Page 6, Partial Plan View 45-D. All piping material specifications are identified in Ref. 2.1.1”
