ARCHITECTURE
The architecture of Westinghouse’s Nuclear Engineering Headquarters is Post-modern Corporate architecture. A strong emphasis is put on symmetry. Building 1 is flanked on either side by Buildings 2 & 3 and are all connected by first floor corridors. The buildings are angled inward to an obtuse "V" shape to draw focus toward the main entrance as well as to create a sense of higher significance or grandeur.
The program of building 1 includes office space, data center, and conference rooms. But the program also includes amenities like a cafeteria/kitchen, gym and sauna. The office finishes are carpet flooring and acoustic ceiling tile.

SUSTAINABILITY FEATURES
This project is going to be at a minimum LEED Certified. The focus of the sustainability of this project is on material selection and construction methods. Materials that have at least five (5) to ten (10) percent recycled material are used. Twenty (20) percent of all building materials are manufactured regionally. And half of that twenty percent is extracted, harvested, or recovered within the region. Low emitting materials, adhesives and sealants are used in the interior of the building. Other LEED points are being obtained for “Construction Waste Management and Disposal” and construction indoor air quality management. The parking areas have bio-retention basins for rain water runoff collection.
CONSTRUCTION
Construction of the Westinghouse Nuclear Engineering Headquarters Campus began in February 2008 and will be complete in May 2010. The Construction Manager at Risk is Turner Construction Company using a design-bid-build delivery method. The total cost of the project is $240 million including Buildings 1,2 and 3. Core and Shell construction is $165 million. Building 1 was completed in two GMP contracts- the first was for Core and Shell with all site work and amenities included and the second was Tenant Improvements.
LIGHTING/ELECTRICAL
The main supply to the building is 480Y/277V, 3-phase, 4-wire. Secondary distribution is provided by the utility company. The main electrical room is located in the basement of Building 1. Two (2) 3000A main distribution switchgears. Also there are two (2) 1500 KVA Transformers to 208Y/120V 3-phase, 4-wire. For Life Safety Systems, a 500KW generator is provided. An 1500KW Emergency Back-up generator is provided to maintain data files in the Data Center room as well as other data storage throughout the building.
The majority of office space has 1x4 fluorescent parabolic trough fixtures. The office areas were designed to be open floor plans to allow as much natural daylighting as possible to cut down on lighting loads throughtout the day. Occupancy sensors cut down on the lighting load an additional amount. Site lighting is done with metal halide fixtures.
MECHANICAL
The vast majority of the office building is conditioned with a Variable Air Volume (VAV) System. Fan Powered Boxes are used to condition the perimeter and core while the VAV Terminal Boxes handle the interior office area. Computer Room Cooling (CRAC) units are used to condition the Data Center. The CRAC units are down flow, cold water distribution.
Conditioning for Building 1 is handled by three (3)-450 Ton chillers with three (3)-450 Ton cooling towers in the Mechanical Penthouse. For venilation of Building 1 there are four (4) AHU's (air handling units) to bring in about 40% outside air for the office areas. Separate AHU's ventilate individually the Electrical room and Mechanical room. Total design CFM to the building is 293,600CFM. It should be noted that Building's 2 & 3 have air handling units that use energy recovery or energy wheels.
Natural Gas and Electric Re-heating Coils are the primary heating source for the building units.
All the mechanical equipment is controlled by peer-to-peer network of DDC PID controllers in a BACnet System.
STRUCTURAL
The foundation of Building 1 is Drilled Concrete Piers that range from 7 to 31 feet deep. The caissons are topped with grade beams. The superstructure is primarily steel frame construction. The columns range in size from W14x61 to W14x233. The primary lateral support in the office areas are from steel girders and beams. The girders are most commonly W24x55 and the beams are typically W18x35. The Mechanical Penthouse is supported by W24x68 girders and W18x40 beams. The roof structural system is primarily W21x44 girders with open web joist of 28K10.
The flooring system is slab on deck. 2.5" Lightweight Concrete slabs on 2"-22 Gauge Composite Deck with 6x6-W2.1xW2.1 WWF.
The exterior walls are curtainwalls with reinforced CMU supporting the brick exterior.
FIRE PROTECTION
A Fire Pump Room is provided for the 1000gpm fire system pump. The majority of Building 1 uses a wet sprinkler stand pipe system. The Data Center uses FE-25 clean agent for fire protection.
TRANSPORTATION
Four (4) passenger elevators and one (1) service elevator are provided in the core portion of the lobby. They have a travelling speed of 100fpm, a volume of 68"x51"x96" and a maximum capacity of 2000lb.
There are three (3) stairwells in Building 1: east, center, and west wings. The east and west wing stairwells go up to Mechanical Penthouse.
SECURITY SYSTEMS
Cameras, card readers and personnel are planned for the campus. Other details not available.
TELECOMMUNICATIONS
All telecom systems are being handled by Westinghouse (tenant). Three (3) telecom rooms were provided on every floor. Back boxes provided and coordinating routes were planned. Basic telephone cable were installed for external use and emergency use. |
