| Thursday was the third day of classes. Our group divided into 2 sections for the field exercise. My section drew the job of helping to mix the shotcrete and run the pumping machine. The other section was spraying the shotcrete on the inside of the 20 foot dome. Our sections would trade jobs on Friday. |
