2 Provide a concise project description in the following box (one page maximum). Include the significant aspects of the project and their relationship to the judging criteria. When completed later this year, Comcast Technology Center will be an urban alternative to the sprawling suburban high-tech campuses of Silicon Valley. This high-density development will be a thriving center of innovation and is expected to produce 2,800 permanent jobs and an annual economic impact of more than $720 million. The Comcast Technology Center is a 60-story, mixed-use building, with 1.5 million square feet of research and development space and will serve as an incubator for new apps, software and services. The 1,121- foot-tall LEED Platinum tower features a glass façade, glass elevators, and three-story atriums with green space located every three office floors. The top 12 stories will function as a luxury Four Seasons hotel, with more than 200 rooms and amenities that include a spa, fitness center, event space and a rooftop restaurant, with a 360- degree view of the city. Rail transportation and other city services will be easily accessible via a subterranean concourse that connects to the Suburban Station regional rail hub. In addition, there will be two levels of belowgrade parking. The winter garden plaza with restaurant and retail space is located at the street level. At a Glance 60-Story Office/Television Studio/Hotel Building 1.8 Million Gross Square Feet, 1121 Tall, The 9th tallest building in the U.S. Concrete Asymmetrical Split Concrete Core, Steel Floor Framing, Concrete on Metal Deck LEED Platinum Goal A Sampling of Significant Structural Features Structural Lateral System The primary lateral system consists of a concrete core which is positioned eccentrically on the west side of the plan to allow for the largest possible uninterrupted floor plan. The core splits to create a central East-West vision corridor which is a key component of the architectural project vision. The core not only steps as the low-rise and mid-rise elevators drop out but the east and west walls transfer to the center of the hotel floor plate allowing for a more efficient hotel room configuration. The asymmetrical split concrete core is supplemented by five sloshing damper tanks to increase occupant comfort at the hotel floors. The dampers are positioned to control accelerations in the primary X-Y axes as well torsional velocities propagated by wind buffering from the 58-story Comcast Center located on the next block. Office Floors With the core located so as to provide the large unencumbered floor plate, the floors are positioned into three story groups with a sky gardens at the east façade of each group. The base floor of each group is the entire floor plate with middle floor cut back 60 at the center bay and the top floor cut back 30 feet to create a large atrium space in each group of floors. These groupings are accented on the façade with the diagonal bracing which supplements the lateral system. Core Designed for Eccentric Crane Loading The concrete subcontractor proposed the use of a tower crane mounted on the east face of the core. Thornton Tomasetti reanalyzed the core for the loads imposed by the crane and modified the design to accommodate this process. The result of this collaboration between design team and contractor allowed for the elimination of floor leave outs and accelerated core and floor construction. The Lantern 120-foot-tall braced steel frame tower constructed at the top of the concrete core, the Lantern is clad in curtain wall and will be backlit to create an iconic presence in the city. The Tunnel A pedestrian tunnel was created under 18th Street to allow occupants indoor access to the regional transportation hub, Suburban Station. Artwork The public spaces will have multiple large-scale pieces commissioned for the project including the Conrad Shallcross piece Exploded Paradigm and an LED feature by Jenny Holzer which will create the ceiling of the five-story escalator to the hotel ballroom.
