Phase
I of this project encompasses 960,000 square feet and
includes a 13-story office tower, structured parking
for 4,000 cars, and one of the world’s largest
column-free trading facilities. The project accommodates
2,200 employees (1,000 on the trading floor) and contains
offices, a 25,000 square foot cafeteria and kitchen,
multi-media room and conference center, a 50,000 square
foot Tier IV data center and a total life/health club
facility. Infrastructure designed on the basis of Tier
IV for Phase I includes a 3000-ton chiller plant, 500-ton
condenser water plant, a 500 horsepower dual-fired boiler
plant, 100,000 gallon on-site water storage, as well
as supplemental air conditioning and power design for
the trading arena. The emergency power system consists
of (4) 1750 KW generators in an N+1 configuration. The
critical power infrastructure consists of (2) 1500 KW
UPS systems configured in a 2N topology. The utility
company service to the project consisted of three H.V.
feeders run in divergently routed underground duct banks
networked together within the building; two groups of
transformer vaults (six transformers total); switchgear
rooms and ATS equipment located remote from each other
by 150 foot horizontal and two floor vertical separations
to insure continuous service in case of fire and/or
flooding. Phase II involved the expansion of the existing
trading floor by 400 traders and required an enhancement
to the critical infrastructure including the addition
of a fifth 1750 KW generator, and the upgrading of the
UPS capacity with the addition of a 1000 KW UPS system.
Flexibility for workstations in open office areas was
achieved through the use of a two-level raised flooring
under which all electrical and tel/data cabling is distributed
as well as a return air plenum. A continuous return
air plenum was provided below the trading floor and
flexible ducts are provided to remove heat from the
trading desks. Modular electrical distribution junction
boxes with power from electrical panels are located
regularly and contain circuitry adequate for the maximum
density occupancy of each entire floor. Power and tel/data
can be brought to newly added or reconfigured workstations
by relocating the raised floor hatch boxes, circuitry
and whips to the new locations. This system proved so
successful that it even allows the client to relocate
traders into areas originally engineered for standard
office space.
