Part I

Wall Forms $(6$ points$)$

If a ${12}^{\text{'}\text{'}}$ wide by ${12}^{\text{'}}$ tall concrete wall has formwork designed as shown in Figure $9\mathrm{.}1,$ determine the following if the wall is $150\text{'}$ long. Ignore the bulkhead material. Assume plywood is used as form material $($diagram shows board sheathing on one side$).$ Form ties shall be $24$ "from the bulkhead, then spaced as noted below.

Sheets of plywood $(\frac{3}{4^{\text{'}\text{'}}}48){150}^{\text{'}}{12}^{\text{'}}2=3600s\frac{F}{48}=$

Board feet of $24$ : studs $(16"$ o$.$c$.,$ not ${24}^{\text{'}\text{'}}$ as shown in Fig. $9\mathrm{.}1),$ top and bottom plates $($studs are ordered as $12\text{'}($installed as $11\text{'}-9"),$ order $16\text{'}$ sticks for the plate materials$)$

Board feet of $26$ : double wales $($order $16\text{'}$ sticks for the wale material$)$

Board feet of $28$ : double wales $($order ${16}^{\text{'}}$ sticks for the wale material$)\frac{28}{12}16$

Total board feet of $24,26,$ and $28\text{'}$s
