Figure 2-21.Sample equipment estimate (page 1).
P-437 not only gives the man-hours required but also
sheet to prepare your detailed estimates and then select
gives a breakdown of the construction efforts by rating
as well as lapse time which is expressed in the
following equation. The P-437 estimates all labor on
10 hour workdays; however, do not mistake this with
the normal workday of 8 man-hours per man-day.
Use detailed material estimates and equipment
estimates to assist you in determining the labor
requirements for constructing a given project. Take the
individual activity quantities from the activity work
the man-hours per unit figure from the appropriate
table in P-405 and multiply it by the quantity to obtain
the total man-hours required. When preparing the
activity estimates in the format covered earlier, you
may use a copy of the activity estimates as a labor
estimate work sheet by adding four columns to it with
the headings of Activity, Quantity, Man-Hours per
Unit, and Total Man-Days required. Prepare work
sheets, whether on the activity work sheet or on
another format, in sufficient detail to provide the
degree of progress control desired.
