REQUEST FOR SPECIFICATION CLARIFICATION

SPECIFICATION ITEM NO.: ____103_________________

PARAGRAPH / SECTION NO:____various________________

TITLE: ____Pump Room Bilge Preservation _

QUESTION:

Paragraph 3.1.1 states to perform 1000 sq ft of mechanical cleaning and 7500 sq ft of resurfacing/ preservation.

Paragraph 3.1.2 states to perform 500 sq ft of mechanical cleaning and 5000 sq ft of resurfacing/ preservation

Reading these line items would lead us to presume that we would be doing spot power tooling, spot coats, cleaning/ washing and painting a full coat to the entire area.

Paragraph 7.2.2 states to perform surface preparation to a WJ-2 standard, SC-2 Condition to all areas of the bilge and 4” up and stations, brackets and anything attached to the bilge, then perform power tooling on inaccessible areas to water blasting to an SP-11 standard

Reading this line would lead us to presume that we are to UHP blast the entire area and power tooling any inaccessible areas to an SP-11 standard.

Paragraph 7.2.6 states to apply the following coating system to all of the prepared surfaces of the tank deck overhead.

What is the real intent of this item?

ANSWER:

The real intent of this item is to water jet blast the entire bilge areas identified in paragraph 3.0. There may be some areas of mechanical cleaning which is stated in paragraph 3.0 as 1000 sq ft and 500 sq ft respectively. The entire bilge will be cleaned, primed and painted.

Para 7.2.6 Should read “ apply the following coating system to all prepared surfaces of this Work Item.”
