CGC MACKINAW – CLARIFICATION

QUESTION: Paragraph 3.2 identifies the lengths and compartment locations of the designated piping to be renewed. However, It does not identify if or how many pipe fittings will be renewed.

Question Is it the intent of the Government for the contractor to perform a visual inspect of the designated piping and identify what additional piping and fittings may need to be renewed?

ANSWER:

Yes, a visual inspection will be part of the work item. There shouldn’t be any additional piping to be renewed other that what is listed in 3.2.1 – 3.2.4. If there is additional piping to be removed, it will be at discretion of CG Inspector (COR). With regard to fittings…typically a coupling (fitting) is added at each cut in the pipe and subsequently welded or silver brazed as necessary, i.e., two welds per coupling.

QUESTION: 1.This work item describes the requirements for the Contractor to inspect and renew 12 fuseable links in Repair Locker 2 (2), Repair Locker 3 (2), Scullery Window (2), Serving Line Windows (4), and Wardroom to Galley Windows (2).

Question: The drawings provided do not provide any amplifying information concerning the counter shutters in the galley, wardroom and scullery. As well SFLC 0000 doesn’t provide any guidance.

In reviewing the material we are under the assumption these are FIRE doors, counter shutters.

If so the following must occur:

1. Federal Fire Code - Requires annual testing and certification [drop testing] of any fire rated door to confine a fire - most of which we deal with are rolling doors and rolling shutters.

2. Any repairs made to a Fire Rated Door requires re-certification [passing the drop test] to comply with Federal Fire Codes.

3. If repairs require further materials then these must be ordered from the manufacturer, installed and then another testing/certification [drop test] must take place.

Please provide clarification and direction on the 12 units in question?
