Prior to the installation of the new cornice, STONE designed a new structural frame to support the propsed cornice at the building. The new frame would allow for the cornice to fit seamlessly like a lego piece to replicate the existing, detailed cornice that was.
Upon discovery of the existing cornice and its condition to be severe, STONE scoped the replacement of the existing cornice with new GRFC. Working close with LPC, we managed to reduce the load of the new cornice as well as retain the existing look and its beauty.
In addition to cornice replacement, STONE also scoped the replacement of any existing, damaged sections of terra cotta found thoughout our close up visual inspections.
STONE scoped the replacement of any damaged window sills with new tinted pre-cast concrete at secondary facades to aesthetically match the adjacent marble sills.
