The Dickey House was completed in 1809 for the coffee and spice merchant Robert Dickey and his family, in what was then a fashionable residential district. The townhouse stood vacant and in disrepair since the September 11 terrorist attacks and was designated a New York City Landmark in 2005. The townhouse has now been incorporated into a public school that extends through the adjacent residential skyscraper’s podium.

Work began with the evaluation of the dilapidated landmark and the use non-destructive evaluation techniques such as baroscopic analysis and surface penetrating radar to determine the overall condition of the facade as well as any internal voids in the mortar. A 150-ton temporary steel skeleton was installed to support the fragile masonry facade following the condition assessment, and it was only then that the interior could be gutted.

The support system stayed in place until completion of the new cast-in-place permanent structure within, which is, in turn, connected to the tower’s floor slabs; a measure that also strengthens the lateral stability of the masonry facade. Once the new concrete floor structures and columns were in place to brace the original brick shell, the steel spider web was cut away with blow torches.
