BLAST MEDIA QUESTIONS AND ANSWERS

Question:

The blast media price list shows the shipping container required for each abrasive. However, in the SOW section 2.0, it says that various packaging sizes may be required and will be determined with each call/order. This would be very difficult to accomplish and still be able to deliver within the 5-business day window. It would be impossible to plan and stock for every packaging size contingency. Please elaborate.

Response:

This verbiage has been removed from the SOW. Only the packaging sizes on the “Pricing List” will be ordered.

It appears that you want pricing per the minimum quantity for each abrasive, and then each increment above that. This might cause the following problems:

a. Difficulty producing and/or stocking enough of each media to meet any particular call/order. An order could be 50 lbs. or 2000 lbs.

b. Difficulty calculating the shipping charges for the same reasons as above (since delivered pricing is required). The price per lb. to ship 50 lbs. is much more than for shipping 1000 or 2000 lbs. at a time.

c. This may lead suppliers to hedge their bets regarding shipping, and make it artificially expensive for each 50 or 250 lb. increment that they quote. If Hill uses 2000# per month of Type II 10/20 plastic, you will receive the best delivered price if supplies know they can ship in 2000 lbs. at a time, and not worry that any given call/order will only be for 250 lbs.

A document labeled “Estimated Order Quantities” has been added which gives order estimates and estimated order frequency based on historical blast media use. However, the Government reserves the right to order only the minimum order quantity as listed on the Pricing List for each blast media type.

What is the Rockwell hardness requirement for the Steel media.

The Rockwell hardness per Mil-S-851D is C-42 to C-52 (see section 3.4.1 of the Mil-Spec). A copy of the Mil-Spec has been posted for your convenience.

Notification:

Type VIII Blast Media has been removed from this requirement. The SOW has been updated to remove all references to Type VIII Blast Media.
