BUILDING STATS
| GENERAL BUILDING DATA |
Building Name: Virginia Advanced Shipbuilding & Carrier Integration Center
Locations: Newport News, VA
Building Occupancy Name: Northrop Grunman Newport News
Occupancy Type: Office/Research/Shipbuilding Facility
Size: 241,000 sf
Number of Stories: Office -8, Laboratory - 3, Parking Structure - 4
Primary Project Team: Clark Nexsen Architecture & Engineering
Dates of Construction: December 1999 - February 2002
Actual Cost: $58 million
Project Delivery: Design-Bid-Build |
| ARCHITECTURE & ENCLOSURE |
The office building is enclosed by a curtain wall that gives the building a light, airy feel. The curved shape of the building gives it the appearance of a tall, glass ship lookng out over the James River. The building is elevated off the ground on concrete "stilts" to help with flooding.
The laboratory wing and parking structure are large, thick concrete structures. This heavy look is a large contrast to the tall, light look of the office building. The lab wing is enclosed by concrete wall panels as well s glazing and precast concrete on the east and west ends. |
| MAJOR CODES |
BOCA National Building Code-1996
AISC Manual of Steel Construction, Load and Resistance Factor Design - Second Edition
ACI 318-95 "Building Code Requirements for Structural Concrete: |
| ROOFING SYSTEM |
The office building uses EPMD on the roof.
The lab wing is a slowing metal roof deck |
| SUSTAINABILITY FEATURES |
| The office building makes use of shading systems to combat the effect of the large amount of glazing on the facade. Three types of rolling shade systems are installed on the interior of the building: two manually operated and one motorized shade. Shades with an independently operating darkening shade are used for the conference spaces, multi-purpose spaces, and the auditorium space. |
| STRUCTURAL SYSTEM |
FOUNDATION
The foundation is a deep foundation system which consists of precast, prestressed concrete driven piles. The piles support a concrete pile cap and grade beam system that supports each building susperstructure.
Materials: 5000psi minimum compressive strength concrete piles
FLOOR SYSTEM
The flooring of the office building is a steel beam system that supports a composite steel deck with lightweight concrete topping. Steel studs are welded to the top flange in order to achive composite action with the concrete deck.
The flooring system of the laboratory wing consists of precast, prestressed concrete double Ts. The double Ts span an average of 60 feet and are supported by precast, prestressed concrete beams.
FRAMING SYSTEM
The framing system of the office tower consists of structural steel columns and braced frames.
The framing system of the laboratory wing consists of precast, prestressed concrete columns. Precast inverted T beams are placed at each column line and used as support beams. |
| The mechanical system contains one 350 ton chiller and one 650 ton chiller totaling 1000 tons. The load is provided by high efficiency water cooled centrifugal chillers. The heating system contains a hot water system with gas fired broilers to produce hot water. Additionally, 3 VAV AHU's located in the penthouse mechanical room provide air for the office tower. 4 VAV AHU's located in the center of the lab building provide the air for the lab building. |
| LIGHTING/ELECTRICAL SYSTEM |
| VASCIC makes use of a 480-280y/120V power distribution system to distribute power throughout the office building. This is done through the use of five transformers located at the service entrance. VASCIC is lit using linear flourescent, compact flourescent, incandescent, halogen, metal halide, and high intensity discharch lamps. Vast dimming control systems are used in the auditorium to control power use. |
The office tower contains a sprinkler system coordinated with the height of the building. The system is required to have a fire pump station that is motor driven and is connected to the facility generator via a power transfer swich for use in emergency situations. Smoke detectors, duct smoke detectors and sprinkler systems are utilized within the building. Finally, voice automated fire alarm systems are used in spaces of assembly type occupancies.
|
| There is a designated telecommunications room on each floor of the office tower. Cable trays placed above the lay-in ceiling tile allow a firber optic cable to be run horizontally to systems furniture connections in the open office areas. |
