Our teaming partner Harry Abramson from Direct Dimensions sent us this great pair of before and after pics of the monument.



Macedonian Monument Project at the U.S. Naval Academy: Cannons Installed

24 Apr


Aeon has completed the restoration of the Macedonian Monument for the U.S. Naval Academy in Annapolis. This year-long project has involved a wide range of services from laser scanning and non-destructive evaluation, concrete restoration and the conservation of bronze plaques, to replication of the original figurehead in mahogany and treatment of the four 18th century cannon. The cannons have just finished a five month process of paint removal and electrolytic reduction to remove all traces of chlorides from deep within the cast iron. The final steps included a phosphoric acid treatment to stabilize the surface prior to painting. Following treatment many details emerged from the old corroded surface that were never visible before. The rededication of this War of 1812 monument is scheduled for April 25.

National Gallery of Art

26 Mar

Recently Aeon has been working at the National Gallery of Art in DC with Balfour Beatty/Smoot and CA Lindman on the cleaning and restoration of this iconic Modern masterpiece. At one of the curtainwalls we have been focused on cleaning thousands of little yellow and black streaks from the glass and concrete surfaces. After careful analysis we came the conclusion that the staining was organic in nature and suspected that it might be insect related. NGA brought in an entomologist who confirmed that what we were seeing was indeed spider droppings from a colony of Wolf Spiders living in the curtainwall. Information on the project can be found here.
