388 Greenwich Street

Kohn Pederson Fox were the architects for Shearson Lehman Plaza, located at 388 Greenwich St. NYC, just a few blocks north of what was then The World Trade Center. It later became the Traveler’s Insurance Building. Now it is being transformed into the new Citigroup Headquarters and a major renovation is taking place.

The North and East facades of the 40 story skyscraper have been cleaned with D/2 Biological Solution. The building material is a fairly porous cast stone that that has attracted significant biological growth and air born pollutants. Work was staged from as many as twelve 30’ swing scaffolds.

Tishman Construction is overseeing the project. Brisk Waterproofing, a Division of Western Waterproofing was the façade cleaning contractor. Integrated Conservation Resources developed the cleaning specifications and supervised the work.  D/2 Biological Solution was supplied by AH Harris.
