Man-Day Equivalent (ME) is the number of man-days
expended (actual man-hours swinging hammers) in a
typical workday, and AF is the availability y factor.
Availability Factor takes into account that Seabees
assigned as direct labor are not available 100% of the
time. Multiply these four factors to figure the man-day
capability (MC). You can use this same equation to
determine the direct labor manning for a detail if you
substitute tasked man-days for MC and plug in AF,

CONSTRUCTION ACTIVITY DURATIONS.
The man-day capability (MC) equation also can be
used to determine construction activity durations
expressed in the following equation:
Duration = MD estimated (CS x AF x ME)
Duration = MD estimated ÷ CS ÷ AF ÷ ME
