Digital Restoration: Richmond Monument

 
The Story:
The history of the Richmond Monument begins almost two centuries ago, when in the winter of 1811 there was a horrible fire that destroyed the Richmond Theater and took the lives of 72 people. The United States government commissioned the great American architect Robert Mills to erect a church and a monument dedicated to the citizens who perished in the flames.

For almost 200 years, the Monumental Church and its monument have stood and taken a barrage of abuse. The jump start of the industrial revolution and mass transportation began to create chemical effects on the weather, namely acid rain. The acid rain would be the downfall of both structures.
The Challenge:
John Milner & Associates was commissioned by the Historic Richmond Foundation to restore and re-install the Richmond Monument as it would have looked when it was first installed in 1812.

The Solution:
  • Carefully 3D laser scan the deteriorating monument onsite
  • Compile a high resolution digital model
  • Work closely with art historians to study the deterioration of the monument as compared to the original
  • Analyze the high resolution digital model against original sketches, notes and photographs
  • Virtually re-build the monument in 3D using all the available information
  • Recreate and align names in CAD and subtract from model
  • Combine the re-built models with the scanned model
  • Rapid-prototype a half-scale model
  • Add hand-sculpted additions to the rapid-prototype
  • Scan the rapid-prototype with new additions
  • Combine new data with the earlier digital model
  • Send the final data to a milling company to be milled from marble             

The final marble monument was installed in the exact same space as the original monument in 2005.
