the existing terrain. As a result, you are given
an initial design profile that is then modified
and adjusted repeatedly as the design
progresses. This profile is the “backbone” of the
road model and is the single greatest influence
on the earthwork quantities that will be
produced by your road.
Questions about cut and fill quantities will be
among the first questions posed about your
design because excavation is such an expensive
part of construction. As a designer, you will be
called upon to minimize cut and fill quantities
and to report your results in detail. Typically,
adjusting the profile to achieve the best
earthwork results is an iterative process—a little
higher here, a little lower there, and run the
volume analysis. Then repeat as many times as
necessary until earthwork results appear to be
the best they can be. As you might guess, or as
you may have experienced, this process is
time-consuming and repetitive.
What if you could click a magic button that
would perform all of these iterations for you?
What if the computing power needed to
perform such an optimization was readily
available? Well, through the cloud via
InfraWorks 360 and a function called Profile
Optimization, this is all a reality. And not only
will Profile Optimization balance your road
earthwork, it will also provide a detailed cost
