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.

8. St. Patrick’s Cathedral, NY

15. Undercroft at Altar

25. 346 Broadway, NYC

26. Former New York Life Building

31. Cross Section through Building

32. Entry Lobby at Center of Building

37. Clock Tower featured in movie 9 ½ Weeks

41. Claiborne Pell Bridge, Newport, RI

43. 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

46. The key element the Bridge Authority wanted to document was the numerous patches in the roadway.

47. Faro Focus:
Quick Scan Time
Fine Detailed Resolution
Perfect Solution

48. 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.

52. Almost 400 scans were taken over a period of nine nights, documenting both lanes (22,500LF / 6,856m) of the bridge.
