The floor slabs are 21/2" concrete over 3" Q decking Building's exterior is comprised of faceted, alternating horizontal bands of polished and flame finished Imperial Red granite from Sweden, stainless steel glass. All windows framing is off-white aluminum, both internally and externally. A two-story high elliptical room is nearly equal in size with the footprint of the base of the Building. A surrounding curtain wall of floor-to-ceiling windows, segmented by bands of stone and stainless steel is carried through to the lobby finishes. Typically 9' 0" finished. Typical slab-to-slab heights are 12' 2".

Heating for exterior zones is provided by hot water heating coils mounted in the CAV fan-powered terminal devices. Individual room thermostats — which are located in every CAV zone — control each terminal device. Each office floor has been separated into a particular number of air conditioning zones, each served by a separate CAV fan-powered terminal device. The number of temperature zones per floor varies according to floor size; this system has the capability to provide a tenant with additional zones by adding or rearranging the fan-powered devices on that floor. There are 3 Trane Centravac centrifugal refrigeration machines, two 600-ton units and one 300-ton unit provide the air handlers with chilled water. Temperatures and pressures are controlled through the Building Management System (BMS). Condensor water is available at the riser in each air-handling unit room for the tenant's use. Domestic city water delivered by two centrifugal, 3-stage, horizontal split-case Weinmann house pumps rated at 40-gpm operated by U.S. Motor 40-hp, 208-volt, 3-phase, 60-hertz induction electric motors. Bathrooms are equipped with a handicap stall and have been modified to be ADA compliant on a limited basis. Some floors have unisex handicap restrooms. The electric service is supplied through individual primary circuits form Con Ed's electrical network to vault type transformers located in the basement transformer vault. Bus ducts from the transformers service the main switchboards with 277/480 volt, three-phase, 4-wire electrical power. The main switchgear includes fusible power switches with high capacity current limiting fuses, single-phase protection and ground fault protection on the bus riser system. One Emergency Diesel Generator is located on Lower Level I. The generator is a Caterpillar SR4 model rated at 500Kw with a fuel capacity of 275 gallons. The generator powers a variety of building systems in the event of power loss, including emergency lighting, one elevator in each bank in addition to the freight, water pumps, the BMS and the PMO Telephone System. Fully sprinklered and equipped with a computer-controlled emergency life safety system that monitors the smoke detectors, water flow devices and the manual pull stations. A new, fully addressable BRD - Firecom Class E system was installed in 2005. A 24 hours, 7 days a week, staffed lobby security console provides closed circuit television surveillance systems. There are two security turnstiles in each of the three elevator banks. - In-House Messenger center - Newsstand - Direct subway access from just outside the building provides connections to Grand Central Terminal, Penn Station, and Port Authority Bus Terminal are all possible from the building.
