I am preparing a schedule, and it includes steel erection for a church. Our steel erection expert says the base rate for erection of this type of structure is $8$ tons per day and that a $15\%$ time allowance is needed for weather delays, mostly delay due to winds higher than the limits of the crane operation. If the current drawings show a total of $73\mathrm{.}5$ tons of steel in the structure, what would be the number of workdays $($rounded up to the next workday$)$ to show for the duration of this work in the schedule, including the time allowance for weather?

$$ A$.7$ workdays

B$.9$ workdays

C$.10$ workdays

D$.11$ workdays

E$.12$ workdays

F$.14$ workdays

G$.16$ workdays
