Bill of Materials (BOM)
« on: January 11, 2018, 01:35:23 PM »
Hardware team - please start creating a BOM. Enter the data in the correct section below. For each item, enter the description and the quantity. When the actual BOM is made, there will also be cost associated with each but that'll be entered later. Not everything needs to be itemized in the final BOM but for now let's just collect the information and we can filter stuff out later. No need to enter small stuff like nuts and bolts.

Raw cost of aluminum based on Sullivan Metal 1/19/17 receipt:

6 inch wide, 1/4 inch thick stock. $64.87 for 12 feet or 864 sq in. => $0.07508 / sq in
4 inch wide, 1/8 inch thick stock. $50.62 for 24 feet or 1152 sq in. => $0.04394 / sq in
1/2 x 1/2 x 1/16 angle aluminum stock (Lowes). $2.18 for 3 ft => $0.73 per linear foot
3/4 x 3/4 x 1/8 angle aluminum stock. $0.72 / linear foot
1 x 1 x 1/8 angle aluminum stock. $24.47 for 25 feet => $0.9788 / linear foot
