demolition, deformation, and demarcation: scanning to enable design and construction by john smits
DESCRIPTION
This presentation will illustrate through real life examples how the Faro laser scanner was used to enable accurate documentation and fast tracking of construction though a better understanding of the physical state of existing conditions. Discussed will be methods of data acquisition in often adverse or cluttered site conditions, scanning in high traffic public areas and active construction sites. A variety of deliverables will be shown: 3D models, 2D drawings, topographic surface mappings, even direct use of printed scalable scan data sections.TRANSCRIPT
Demolition, Deformation and Demarcation
Scanning to Enable
Design & Construction
St. Patrick’s Cathedral, NY
Undercroft at Altar
346 Broadway, NYC
Former New York Life Building McKim Mead & White
1894-1898
Cross Section through Building
Entry Lobby at Center of Building
Clock Tower featured in movie 9 ½ Weeks
Claiborne Pell Bridge, Newport, RI
Project Goals: Scan entire bridge 11,248 LF (3,428m)
Scan at night, complete within two weeks Tie scan data in geo-coordinates
Use data as basis for CAD documents
The key element the Bridge Authority wanted to document was the numerous patches in the roadway.
Faro Focus: Quick Scan Time
Fine Detailed Resolution
Perfect Solution
The Faro Focus 3D and the Faro 330 were used. Scans were taken at 1/4 resolution, set 60’ (18.3m) apart to gain
sufficient detail and resolution of the roadway surface.
Almost 400 scans were taken over a period of nine nights, documenting both lanes (22,500LF / 6,856m) of the bridge.
