REQUEST FOR SPECIFICATION CLARIFICATION

RFC # 012

NAME OF CONTRACTOR: ___________________

SPECIFICATION ITEM NO.: ___021__________________

PARAGRAPH / SECTION NO:__7.2. 7.4, 7.7, Enclosure 2.2.1_____________

TITLE: CLEAN AND GAS FREE TANKS, VOIDS, COFFERDAMS & SPACES

QUESTION:

Paragraph 7.2 states, "...verify sounding of all tanks listed in enclosure 2.2.1 on arrival…"; however, the contractor notes the enclosure does not contain all ballast tanks shown in the Capacity Plan.

Paragraph 7.4 states, "Contents to be temporarily stored are indicated in the enclosure (2.2.1)." However there is no such indication of contents storage in the enclosure.

Paragraph 7.7 states, "Clean and Gas Free tanks and spaces listed in enclosure 2.2.1." Enclosure 2.2.1 provides Capacity (100%) for each tank listed but does not provide the Arrival Condition for each tank.

Will the Government re-issue Enclosure 2.2.1 in order to provide;

1. The Arrival Condition of each tank.

2. The contents to be temporarily stored (if different from paragraph 7.3).

3. Confirmation that the list of tanks provided therein is complete for this availability.

ANSWER:

Revised WI 021 posted to AMRDEC with updates to Enclosure 2.2.1 to modify the tanks required for this availability. The arrival condition of each tank is stated in paragraph 7.4 in that the ship shall pump down the contents to the low suction. Storage requirements are specified in paragraph 7.3 and any storage beyond that will be done on a change order. The list of tanks in Enclosure 2.2.1 is modified and complete for purposes of this availability.
