At
Charter
Estimating,
we
use
formulas
that
will
take
the
stress
out
of
estimating
and
allocation
of
manpower.

how
to
correctly
man
load
your
projects
to
increase

and
lower
your
overhead!
Below
is
an
example
of
the
figures
we
calculate.
Average
Man-Loading Number
of
estimated
man-hours
=
2,910
Number
of
hours
in
a
work
day
=
8
Number
of
work
days
in
one
month
=
20
Number
of
months
in
contract
=
6
2,910
(total
hours) ÷
8
(hours
per
day)
=
364
work
days.
It
will
take
one
man
364
days
to
complete
the
contract.
The
contract
says
the
job
should
be
completed
in
6
months.
6
(months)
x
20
(work
days
per
month)
=
120
contract
days
364
(days
for
1
man) ÷
120
(contract
days)
=
3
