The two laborers from Problem $1$ will be transporting lumber from the stockpile to the

work area, which is an average of $65$ feet. STATE YOUR ASSUMPTIONS for a cycle

time based on the example from the text. The crew of $5$ carpenters can build formwork

up to $6$ above ground at a rate of $32$ sf$/$hour $($if the lumber is available$).$ Based on a $45$

min hour, determine the probable rate for building $2$x$6$ formwork and production unit

cost for the concrete formwork in $$/$sf$.$
