The Efficiencies of Laser Scanning for Historic Architectural Reproduction.

Before laser scan technology, documenting historic elements made reproduction work an uncertain and tedious process. For example, it was understood that certain exterior terra cotta elements of an Upper Manhattan apartment building would have to be replaced. The issue was that they weren’t scheduled to be accessed until the erection of the scaffolding, six months off, so any measurements or takeoffs would have to wait until then. Since custom reproduction of architectural terra cotta requires several months of turnaround time, this would significantly delay the project. Corinthian Data Capture of Wyandanch, New York accelerated that process by recording the exterior facades of the building, from the ground, using 3D laser scan technology. This process was able to accurately capture measureable data for the first 10 stories of this historic building and give it to the terracotta manufacturer. This gave all parties a head start on the work. In cases like this, laser scanning can efficiently replace tedious documenting operations such as moldmaking or sketch artists in the field.
