The following are the answers to the Request for Clarifications:

QUESTION NO. 10:

Work Item D-25, Sea Valve (2.5 Inches And Smaller) Renewal:

These questions originated from Bay Valve Company, a major supplier and overhaul facility for valves:

1) Renewal spec says replacement valves will be bronze with Monel trim (paragraph 3.3), but lists 2 ea. ½” butterfly valves (5-212-1-TV and 5-212-2-TV).

To our knowledge, no manufacturer has ever made ½” butterfly valves in any material. Please confirm size and type of valve, and end connection (flanged, threaded, Sil-brazed union, etc.)

2) Valve 3-301-2-FREON is listed as a scupper. To our knowledge, no manufacturer makes a 1” scupper. Please confirm size and type of valve, end connection, and Manufacturer..

3) 5 ea. 1-1/2” butterfly valves (3-079-4-SD, 5-243-1-ALP, 5-243-1-TV, 5-243-2-TV, 5-102-2-TV) are no longer made in bronze bodies with Monel trim. Additionally, there are very few manufacturers who currently produce this size in industrial butterfly valves. Please advise if alternate materials are acceptable, and, if so, if they are lug style or wafer style, with lever handle operators.

As an alternative, it may be possible to adapt the 1-1/2” piping to utilize 2” valves. Another option would be GFM.

ANSWER:

5-212-1-TV is descope;

5-212-2-TV is descope; 3-301-2-FREON: is descope;

3-079-4-SD no alternative materials or valve sizes are acceptable. Paragraph 1.1 indicates Contractor may overhaul vice renew (price for overhaul should be included in the proposed price);

5-243-1 ALP is descope;

5-243-1 TV is descope;

5-243-2 TV is descope;

5-102-2 TV, no alternative materials or valve sizes are acceptable. Paragraph 1.1 indicates Contractor may overhaul vice renew (price for overhaul should be included in the proposed price).

QUESTION NO. 11:

Work item D-26, Sea Valve (Larger Than 2.5 Inches) Overhaul;

This question originated from Bay Valve Company, a major supplier and overhaul facility for valves:

Please confirm that valve 3-067-2-WW in the overhaul spec listed as a 4” X 5” Butterfly valve is actually a scupper. (There is no such thing as a 4” X 5” B’fly valve.)
