(27 points, total) Each alternative: 4 points but must include Wood species required, either Mixed Oak (MO) or Douglas Fir (DF) ( point), sheeting size and horizontal spacing ( point each); wale size and vertical spacing ( point each); and cross brace size, vertical spacing, and horizontal spacing ( point each)) Show units ( points for showing units on all). Note: the sizes of timbers should be in units of inches so show the units. Simply writing 6x8 is incorrect since they must be full sawn so 6"x8" is the correct reference. It is also valid to just state "closed" for the sheeting because that just means the sheeting is placed such that the gap between each vertical sheeting member is as tight as reasonably possible.
