10 hours in duration (7 am to 5 pm Monday thru Friday) and one work day that is
approximately 5 hours in duration (8 am to 1 pm Saturday).
a Construction meetings will occur weekly during construction and will be no longer than
one hour in length.
a There will be one material source for each type of earthwork material.
