Completed in 1980, the Carrier Dome is a 49,262-seat sports stadium covering 7.5 acres on the campus of Syracuse University in central New York State. In addition to sporting events, the Dome has played host to Olympic champion ice skating shows, world class concerts, commencement and various academic convocations as well as community events. At the time of completion, it was ranked the 5th largest domed stadium in the US and the first of its kind in the Northeast. The Carrier Dome remains the largest structure of its kind on a college campus in the country.
In April, 2012, JPW Riggers, Inc. contracted Delta Engineers, Architects & Land Surveyors to perform a High Definition Laser Scan survey for the installation of a 360 Degree Ribbon Board Display signage to show ribbon-style video clips, animation, advertisements and real time scores and statistics.
The HD Laser Scanner provides high quality 3-dimensional seamless images of an image at a rate of over 50,000 points per second and scans and logs all points to form a complete picture. Each point on the scan is then imported into proprietary software for 2D or 3D modeling and rendering in Auto CAD and/or a fly-through video.
The top of the concrete area that the 360 Ribbon Board Display was being installed on, was estimated to vary by approximately 6 inches around the perimeter. Since the new display needed to be perfectly level for installation, Delta performed the high definition laser scan of this display area to verify and determine the difference in elevation of the structure by laying out a fixed elevation baseline every 10+I-feet (approximately 260 points) around the face of the concrete. A drawing was prepared to show this discrepancy in elevations, related to an arbitrary datum set in the Dome in an earlier project.
