Tight sites for construction projects are not uncommon in New York. More often than not, project teams rise to the challenge. But when that site is landlocked by subway stations on three sides and a landmark theater on another, no room is left for Con Edison vaults below the sidewalks. The project team decided to put the vaults on the 3rd floor of the new, $150 million, 38-story, 575-foot-high, 1.1 million square foot building.

E-J Electric’s team built a complete Con Edison Spot Network within the vaults. This network consists of four 4100-480/277Volt power transformers (with expansion capabilities to six), network protectors and collector bus. E-J ran 5kV power conductors, within concrete-encased five-inch rigid metal conduits that sweep up from behind street level to the 3rd floor.

To deliver base building power E-J installed a lineup of four, 6000Amp service switchgear arrays, feeding four duct risers (one for every nine floors), with tap-offs to transformers. To compensate for the voltage drop experienced at higher floor levels, the bus duct runs are rated at both 4000A and 5000A.

A 1500 watt- rated standby diesel generator provides power for emergency lighting circuits and other vital loads, if utility-supplied power to the building is ever lost.

Combining creativity with technology, a unique façade lighting installation provides dramatic visual identification to this Times Square office tower. E-J Electric also installed an UL-listed lighting protection system for the office tower.
