Gewalt HamiltonAssociates &High-DefinitionSurveying
Gewalt Hamilton Associates is equipped to handle
your most complex project.
To support the professional engineering know-how
and creativity of our 60-person staff, we’ve added
high-definition surveying (HDS) to our range of
services. Our surveyors have the training, expertise
and experience that HDS requires.
Gewalt Hamilton is one of only a few engineering firms
to have HDS, which represents a paradigm shift in
surveying technology. In years to come, HDS will
replace traditional surveying methods for projects
simple and complex, large and small.
Our most important service is meeting our
clients’ needs.
“AT GEWALT HAMILTON
ASSOCIATES, OUR CORE
PHILOSOPHY IS TO PROVIDE
HIGH-QUALITY, TIMELY
SERVICE. HIGH-DEFINITION
SURVEYING ALIGNS
PERFECTLY WITH
THAT PHILOSOPHY.”
BOB HAMILTON, P.E.,PTOE
PRESIDENT
At GHA, we’re early-adopters of technical resources that will be indispensable in the future.

STATE OF THE ART.
Gewalt Hamilton Associates has chosen the Leica
ScanStation high-definition surveying (HDS™)
equipment that combines four critical features:
Full f ield-of-view that captures 360o data from
ceilings, elevated pipes, tall facades, ornamented
surfaces, columns, towers and other difficult-to-
measure areas and structures.
Survey-grade, dual-axis compensation, which
provides freedom, flexibility, and safety in the field.
Survey-grade point accuracy for each
measurement, together with ultra-fine point
spacing at long range that takes optimal advantage of
scan targets and provides unsurpassed registration
accuracy and project control.
Practical range of approximately 300 meters for
90% reflectivity and 134 meters for 18% reflectivity;
HDS has a narrow beam and fine-scanning
capability that produce highly accurate data
from accessible points in the field.
The Leica ScanStation unites state-of-the-art
technology with point-and-shoot simplicity.
That’s the future of surveying, and we have it
at Gewalt Hamilton—now.HDS REMOVES

“HDS lets us survey a busy intersection without stopping traffic. We can analyze steeply sloped terrain from a safe,
remote location. We can work at night. HDS works as hard as we do.”
HDS technology brings unprecedented breadth, depth and scope to surveying. HDS is versatile and can handle the gamut of projects, from single buildings to highway systems.
And it’s f lexible in the field, providing optimal vantage points and crew safety.

Gewalt Hamilton Associates is in its third decade of
providing services for civil site design, transportation
engineering, and surveying. Our portfolio includes
projects for municipalities and governments,
residential subdivisions, office parks and corporate
office sites, shopping malls, hospitals, senior care
facilities and public schools.
As our assignments have grown more complex and
sophisticated, so have our skills and capabilities.
We stay ahead of the curve in technology, with
HDS as a prime example.
On each project, our engineers, surveyors and com-
puter technicians work as a team with the architect,
contractors and others who are committed to
creating a successful result. HDS gives the team
the comprehensive information it needs.

CAPTURE RAW DATA, CREATING A
POINT CLOUD. LATER, BACK AT THE

Gewalt Hamilton Associates uses high-definition
surveying for the added value it brings to our
client services.
Complete and accurate. In most architectural
and engineering projects, surveying is the first
important step. HDS has a 360-degree field-of-view,
registers 3,000+ points per second, and produces
data that’s accurate within 2 mm. Projects begin
with solid, comprehensive information.
Non-invasive. Because HDS is non-invasive, it’s
a natural for the renovation of older buildings or
the restoration of historic landmarks. HDS is also
ideal for surveying intersections, the undersides
of highway overpasses and other areas that
are difficult to access.
Cost-effective. HDS cuts surveying time in the field and
gets complex projects off to a flying start. And HDS
lengthens the life of information. Once a scan is made,
it’s ready to use right away, or a year away. Our com-
puter keeps HDS data as long as it might be needed.
Cutting-edge. HDS technology is the future of
surveying. Gewalt Hamilton has it now, and our trained
staff have the expertise it requires.
Take a look at HDS. Once you see what it can do, you’ll
wonder how you did without it, particularly for complex
projects. We’ll arrange a demonstration whenever,
wherever it’s convenient for you.
Call our survey department at 847-478-9700 to find
out how HDS technology can benefit your project.
“IN TRADITIONAL SURVEYING, YOU PICK A SPOT IN THE FIELD, SET UP, RECORD, THEN REPEAT
THE PROCESS AT 50- OR 100-FOOT INTERVALS. WITH HDS, YOU PICK THE SPOT.
ONCE. FROM THAT VANTAGE POINT, HDS RECORDS THE DOTS AT 3,000 POINTS
PER SECOND. HDS CONNECTS THE DOTS AND CREATES A CLOUD OF DATA—
A POINT CLOUD.”
