ArchKey/Mona Helps Bring Urban Expansion to Life, Assisting in Build-Out of New Eco-Conscious Development

As the D.C. region expanded west, Capital One made big plans for a new expansion. Sitting atop a 26-acre development, the new Capital One Center in Tysons Corner now one of the up-and-coming urban development and has been awarded Best New Development 2022 by Washington Business Journal. Sporting offices, a hotel, retail space, performing arts center, public green spaces, sculpture gardens, grocery store, bars, and restaurants, this project encompasses 2.7 million square feet of multi-use office, hospitality, and retail spaces, along with parking garages and the performing arts center. Our team handled a comprehensive scope of work from electrical and distribution capabilities to substation and life safety systems across the Capital One Tower (Block B), mixed-use tower (Block A) and Capital One Hall (Block C).

Capital One Tower, Block B

Capital One Tower, a new 1.7 million square foot building in Tyson’s Corner, stands nearly 470 feet tall. It’s a mixed-use building with eight floors of podium (garage, and multi-purpose space), followed by a high-rise tower (floors 9-31) housing fully outfitted office space. Additionally, the building includes two stories of Penthouse space and will serve as the international headquarters for the bank.

Capital One Corner, Block A

Situated in the Tysons Corner neighborhood, Block A, a 24-story class A twin-tower building, totals 900,000 square feet. It will house 850,000 square feet of office spaces, and two levels of future retail space spanning 20 floors. In alignment with their commitment to environmental sustainability, CapitalOne is targeting LEED Gold certification for this building with multiple eco-concious features. These include a striking 12-story atrium interlinked by connecting bridges, innovative rain-water capture and re-use program, smart lighting controls, and 33 EV charging stations placed throughout the four-level underground and ten-level above-ground parking garage.

Capital One Center, Block C

As part of Capital One Center, Capital One Hall is a high-end performance and community space featuring a 1,600-seat main theater, a 225-seat black-box theater and a large 4-story open event atrium. A 12-acre rooftop park features a 230-seat amphitheater, sculpture garden and biergarten. Anticipating a LEED NC Gold certification, the building’s HVAC and energy recovery systems are anticipated to reduce energy consumption by 27% compared to comparable code-compliant buildings.

Scope of Work

Our team’s work on Capital One Center encompassed the Capital One Tower (Block B), mixed-use tower (Block A) and Capital One Hall (Block C).

Capital One Tower, Block B

On the Capital One Tower, our scope of work involved furnishing the complete electrical and life safety system. The service to the building comprises siz 4000 amp 480/277 volt switchboards with emergency backup from five 900kw diesel generators (three on level 4 and two on the penthouse level). This building boasts over 15,000 specialty lights along with a state-of-the-art lighting control system.

Capital One Corner, Block A

Work on Block A consisted of power distribution to the facility achieved through bus ducts and IPAC substations. The incoming service feeds included two 35kv, 10 mega watt transformers, which then fed two 5kv metal clad switchgears and subsequently twelve 5kv substations. Additionally, we installed 33 Chargepoint CT4000 series EV chargers. ArchKey/Mona is responsible for the core and shell of the building, covering 29 elevators, the Lime Light lighting control system in the garage, and the high-rise voice fire alarm system.

Capital One Hall, Block C

Finally for Block C, the Capital One Hall, our work included setting up power distribution infrastructure for the performing arts and retail spaces, hotel, Wegmans Grocery Store, and two additional future towers. Utility services feed into one 4000A switchboard, ninety-two 5000A switchboards, and sixty-five distribution and brandch panelboards. Multiple busways run to feed the hotel and Wegman’s electrical room, which is distributed from the basement up to hotel level 24.
