Scanning at the World Trade Center

"We at Medina Consultants had the opportunity to use 3D laser scanning technology at the World Trade Center (WTC) Ground Zero site shortly after reconstruction had begun following the attacks of September 11th. The project supported re-establishing a subway station in the WTC �bathtub,� the 3' thick x 70' high slurry wall constructed many years ago to provide support for the proposed construction of the site

Our total time in the field was only nine hours. While scanning, we did spot-accuracy checks, inversing between targets with both our Cyrax and the Leica total station. Our worst-case check was 0.015'.
