The Heinrich Heine Memorial, also known as the Lorelei Fountain was designed and fabricated in Germany for erection in Dusseldorf. It ended up on the Grand Concourse in The Bronx in NYC where it was moved several times and heavily vandalized. In 1999 the Municipal Art Society raised funds for its restoration. D/2 Biological Solution was specified for its cleaning. Joan Berkowitz was the conservator and still gives the fountain a light D/2 maintenance spraying every other year.
455 Central Park West’s restoration was completed in 2005. Built by John Jacob Astor III in 1884 as the New York Cancer Hospital it lay in ruins for more than 25 years until the architectural firms of RKTB and Perkins Eastman were retained to restore and convert it into luxury housing. Jablonski Building Conservation was retained as building conservator and specified D/2 Biological Solution for removal of biological growth from the various facade stone and masonry substrates.
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.
The New York Public Library’s landmarked Fifth Avenue building was designed by architects Carrère and Hastings in 1897 and completed in 1911. In celebration of the iconic building’s 100th anniversary, it was given a facelift with D/2, washing away years of dirt and grime.
