(The American Surveyor • January/February 2005) The successful use of laser scanning/high-definition surveying for industrial plant as-builts was well-documented when METCO Services, first began to look into the technology. Believing that automobile assembly plants in the area might provide fertile opportunities for scanning services, the company demonstrated an early interest in getting into laser scanning. plus

(Reporter 50, Apr 2004) New Jersey Department of
Transport (DOT) is replacing
a traffic circle at a heavy
traffic intersection of State
routes 30 and 130. A professional
engineering design
and consulting firm hired
Medina Consultants, P.C. to
provide accurate crosssections
and a digital terrain
model (DTM) of the existing
four and six-lane roadway.
The contract was awarded
based on conventional and
aerial survey techniques.
After winning the bid,
Medina Consultants agreed
to use their Cyrax® 2500
(since rebranded as
HDS2500) for the project.
The Cyrax system could save
$24,000 budgeted for lane
closure costs and halve
survey labor to five days
with a four-person crew from
20 days with a two-person
crew. In addition, operators
would not be at risk in traffic
lanes and drivers would not
be aggravated by closing
lanes. plus

The Pennsylvania Department of Transportation contracted rock removal from a rock face overlooking SR322 at Mt. Pleasant, PA. In order to verify the contractor’s estimate regarding the the volume of rock removed, PennDOT scanned the face using the Cyrax system. Contour maps generated directly within Cyra Software were exported to AutoCAD® and MicroStation®. Volumetric information was compared to that prepared by the contractor. plus

“What we have been seeing is that Cyrax can gather thousands of points in one day which would take us weeks using traditional methods”

“ We were able to survey the highway much safer and faster, without lane closures, plus we provided greater detail for our road designers. We
estimated that using Cyrax on our first project (Hwy 880) cost roughly the same as using traditional methods. On our second project (Hwys 101
and 85) we just about doubled our production.” plus
