REQUEST FOR SPECIFICATION CLARIFICATION

NAME OF CONTRACTOR:___________

SPECIFICATION ITEM NO.: 0102

PARAGRAPH / SECTION NO:Various

TITLE: ANTI ROLL TANK PRESERVATION

QUESTION:

1.

Can the government provide the surface area of the tank listed in 3.1.1? The drawings furnished lack the detail to accurately calculate the surface area.

2.

The government is furnishing 90 gallons of total paint (4.1) and 200 gallons of thinner. This seems unusual. Please confirm that this is correct.

3.

The specified product, Ameron 240, can be applied at steel tempreatures as low as 23 degrees (F) and even lower with the available cold weather curing agent. Will it be necessary to include the cost of heaters as per para’s 7.1.4c & d since the climate at the shipyard will make heaters unnecessary?

4.

Should the removal of any existing mud, muck or scale be allowed for during the cleaning process (7.2.1)? If so, how much?

ANSWER:

1. Assume 7,000 SF.

2. There will be sufficient paint provided as GFM. Government will double check the quantities.

3. Paint will need to be applied in the appropriate environment in accordance with the work item and the paint rep. Provide cost estimate appropriately.

4. The tank will need to be surface prepped in accordance with the work item. Any and all mud and muck should be removed. For estimating purposes assume for moderate scaling.
