# Estimate Laboring
|
|
|
|
In construction estimating,
|
|
**laboring** is the process of calculating the labor hours required
|
|
to install takeoff material.
|
|
|
|
## Labor Factoring
|
|
|
|
**Labor factoring** is the adjustment of base labor hours
|
|
to account for adverse or beneficial working conditions.
|
|
|
|
Labor factors are most often used to increase labor,
|
|
but decrease is also possible,
|
|
especially efficiency gains due to repetitive work.
|
|
|
|
%%
|
|
|
|
## TODO
|
|
|
|
Discuss purpose and practice of labor factoring,
|
|
briefly mention impracticality.
|

## Software Integration
|
|
|
|
%% TODO: move to more appropriate article. %%
|
|
|
|
calculate labor hours utilizing a comprehensive set of factors
|
|
not practical with traditional methods.
|
|
The use of this framework will provide:
|
|
|
|
* more accurate projections for project schedule,
|
|
* more insightful analysis of historical labor data, and
|
|
* a more rewarding estimating workflow.
|
|
|
|
For myself, and I suspect for many other estimators,
|
|
laboring is the most interesting and rewarding part of the job.
|
|
Discussions of human factors are far more engaging
|
|
than those of statistical analysis.
|
|
|
|
%%
|
|
TODO: discuss the necessity of comprehensive labor consumption insights
|
|
and visualizations which are not currently feasible
|
|
as an expectation of owners and contractors.
|
|
|
|
Estimators know that doubling crew won't double production,
|
|
but we must be able to offer evidence as such.
|
|
%%
|
|
|
|
Tables of labor factors given certain conditions
|
|
can be converted to functions using regressions.
|
|
|
|
## Going Further
|
|
|
|
Base labor units suggest a highly functional nature,
|
|
most sensitive to _weight_.
|
|
Greater understanding of this relationship would make practical
|
|
the prediction of labor of unstudied items.
