New York City City (pop., 2000: 8,008,278), southeastern New York, at the mouth of the Hudson River. The largest city in the U.S. . Designed by Wiley and Corbett in 1939, the Criminal Courts Building is a 17-story art deco-influenced structure with a monumental ziggurat-shaped tower. Composed of three wings on the east and west elevations, the building is faced with buff-colored limestone above a polished blackish green granite three-story base. Vertical strips of windows with cast aluminum spandrel spandrel Roughly triangular area on either side of an arch, bounded by a line running horizontally through its apex, a line rising vertically from the springing of the arch, and the exterior curve of the arch. panels and ornamental caps alternate between flat ashlar limestone piers. Multiple setbacks begin at the 17th floor, culminating in the 24-story central tower. The building facade suffers from deferred maintenance. Breaches in the building envelope A building envelope is the separation between the interior and the exterior environments of a building. It serves as the outer shell to protect the indoor environment as well as to facilitate its climate control. , particularly at parapets and deteriorated mortar joints, has led to serious water infiltration infiltration /in·fil·tra·tion/ (in?fil-tra´shun) 1. the pathological diffusion or accumulation in a tissue or cells of substances not normal to it or in amounts in excess of the normal. 2. infiltrate (2). , causing corrosion of stone anchors that is exacerbated by the freeze/thaw movement of trapped moisture. As a result, the stone facade materials exhibit displaced displaced see displacement. units and a conspicuous pattern of cracks and spalls at the corner of units. SHCA conducted an exterior evaluation to document exterior damage and deterioration. A comprehensive investigative probe campaign has been completed documenting the underlying configurations and conditions at each parapet level and at locations with evident distress. Based on the information revealed from this investigation, SHCA prepared construction documents for the work required to restore the facade to its original condition. Construction will be performed in two phases. Phase I will address unsafe conditions and is set to commence before the end of 2003. Phase 2 will restore the balance of the exterior and is currently out for bid. Work is expected to be complete by 2005. |
