Table 2-4. - Production Efficiency Guide Factor Chart

MC = DL x WD x ME x AF

Use DL to represent the number of direct labor assigned, WD for the number of available workdays, 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,

ME, and WD. The number of workdays is taken from the deployment calendar.

ME = WD - Lunch - Travel - Breaks- Actual MHRS/work day

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)

or

Duration = MD estimated ÷ CS ÷ AF ÷ ME
