QUESTION:

Background: The Bill of Material for drawing 8497002 (items 1 thru 4) calls for specific aluminum alloys and tempers (AL 5086-H32 & AL 5052-H32). Callouts for AL 5086-H32 and AL 5052-H32 are for non-critical secondary structure. Substituting to AL 5083-H116 will have no adverse effects on the foundation(s), and will greatly reduce material costs. Some current contracts with ABS approved mills purchase AL 5083-H116 in bulk.

Can 5083-H116 be substituted for all callouts of 5086-H32 or 5052-H32?

ANSWER:

5083-H116 can be substituted. All changes shall be incorporated into redlines and final As-built drawings.
