The Merrill Lynch Denver Operations Center is an office campus complex located in the Meridian Business Center office park in southeast Denver. The master plan calls for five office buildings totaling 900,000 sf and three structural parking decks. During the first phase a 285,000 sf four-story building, a 140,000 sf four-story building and one parking deck were designed and constructed. Since then, another 140,000 sf four-story building and parking deck have been designed but construction has not yet begun. |
The mechanical and electrical systems for each building are stand alone so that each building could be sold separately if necessary at a later date. The loads for each building were established for a high density, PC intensive use and flexibility was a major design criteria. Each building includes a large computer room in the basement, a large lobby/atrium and one building has a large employee cafeteria on the first floor. |
Each building has a central boiler plant on the roof. A central chiller plant in the basement with either one or two built-up air handling systems utilizing plug type fans with variable frequency drives. The systems and or risers are tied together on each floor for optimal flexibility and serve a series of hot water fan-powered VAV boxes for perimeter zones and cooling only VAV boxes for interior zones. The systems were sized and arranged for staggered occupancy, multiple work shifts and for the addition of humidification in the future. |
The electrical requirements for each building are served by one or two 3000 amp, 480-volt, 3-phase, 4-wire main distribution center located on the lower level. A standby power emergency generator has been provided for each building. Each computer room is served from the main distribution center and backed up by a UPS system. The distribution within each building consists of 480-volt risers which are tapped on each floor by a K-13 rated transformer. A raised floor system is utilized throughout the facility for maximum flexibility of power and data distribution to the workstations. Separate neutrals are provided for all branch circuits feeding workstations and transient voltage surge suppression is installed in the main distribution centers and all 120/208 volt panelboards serving workstations. |
