| To find the number of
timbers needed. |
|
| Divide the total square
footage of wall by the appropriate number above. Include
bottom row and dead men. Approximately 1 dead men per
four timbers is figured into the total. |
|
|
| Example: 200 sq ft wall
/ 3.33 sq ft (5" timbers) = 60 timbers x 0.25 (for deadmen)
= 15. Total timbers needed 60 + 15 = 75 timbers. |
