and then place it horizontally from the point at which
represents normal Seabee production under average
it intersected the diagonal line. You can now read the
delay factor from the values given on the right-hand
side of the chart. Lets look at an example of the
process of adjusting man-hour estimates.
Assume that from the work estimate taken from
the tables in P-405, you find that 6 man-hours are
needed for a given unit of work. To adjust this figure
to the conditions evaluated on your job, assume that
the average of foreseen conditions you rated is 87
percent. The corresponding delay factor read from the
production efficiency graph is 0.80. You find the
adjusted man-hour estimate by multiplying this delay
factor by the man-hours from the estimating tables
(6 MH x 0.8 = 4.8 as the adjusted man-hour estimate).
The activities in the various labor estimating
tables are divided into units of measurement
commonly associated with each craft and material
takeoff quantities. There is only one amount of
man-hour effort per unit of work. This number
conditions. As used herein, 1 man-day equals 8
man-hours of direct labor.
No two jobs are exactly alike, nor do they have
exactly the same conditions. Therefore, you, as the
estimator, must exercise some judgment about the
project that is being planned. The production
efficiency guide chart and graph (table 2-4 and fig.
2-14) are provided to assist you in weighing the many
factors that contribute to varying production
conditions and the eventual completion of a project.
You can then translate what is known about a
particular project and produce a more accurate
quantity from the average figures given on the labor
