Zoning: “B”, Business
Building Envelope: The exterior wall cladding is made up of various types of masonry and brick, as well as metal paneling. The flat roofing is a single-ply roofing membrane while the gabled roof areas are comprised of standing seam metal roofing.
Construction:
The building site is located in close vicinity to a small lake, with the surrounding soils being comprised of medium compact to compact sand. To accommodate the relatively small bearing strength of the soil, a friction steel pile foundation system was designed. This system consists of steel HP shapes being driven into the ground to a certain depth that guarantees the friction between the pile and soil provides the correct amount of load bearing capacity.
Structural System:
There is a deep foundation system to support all building columns, walls, grade beams and other foundation elements. The deep foundation elements are comprised of friction steel H-piles in native medium compact to compact sand. All H-piles consist of 75 foot long HP12x84 sections with concrete pile caps. The concrete pile caps are of reinforced concrete construction with their top elevation at a minimum depth of 3'-6" below finished grade as to prevent frost heave. The dimensions of the caps range from 3'x3' for a single H-pile element up to 13'x11'-8" for a 7 H-pile element. The typical slab on grade used in the building is an 8 inch thick two way slab system spanning bays of 20'x20'.All concrete used has a minimum compressive strength of 3000 psi.
The main column system is made up of wide flange shapes ranging in size from W14x43 to W14x311. Typically, these columns rest upon the deep foundation system and span 72 feet to the penthouse level with a column splice at an elevation of 52 feet (falling within the third story). In areas where the building is only one story, the columns are composed of W14x43 and W14x61 wide flange shapes as well as hollow structural steel shapes of HSS6x6x1/4 sections. These columns also sit on the deep foundation system but only span 14 feet to the top of the first story.
The typical framing system for the Visteon Village Corporate Center is composed of structural steel composite beams and girders. The supported floors will consist of 40 foot long wide flange shapes spanning a column free space. The typical bay for each floor is 40'x20' with wide flange beams spaced at 10' on center supporting 3" composite metal floor deck with 3-1/4" light weight concrete fill providing a total slab depth of 6-1/4".
All lateral loads caused by wind and seismic forces are resisted by structural steel moment frames. There are five moment frames running in the North/South direction of analysis and six moment frames running in the East/West direction of analysis. Each moment frame consists of multistory wide flange columns and wide flange beams.
Mechanical:
The Visteon Village Corporate Center utilizes a unique under-floor air distribution system (UFADS) throughout most of the building's areas. The system uses the plenum below the raised access floor to distribute supply air to diffusers installed in the raised access floor. The penthouse air-handling units pressurize the plenum below the floor to a constant pressure. Using this system provides many advantages over a traditional overhead system such as improved thermal comfort and indoor air quality.
The penthouse air handling units are configured using 2" double-wall construction, 100% outside air economizer cycle, 35% pre-filters, 95% final filters, pumped heating coil, draw-through cooling coil, secondary return air mixing box, centrifugal plenum supply fan with variable frequency drive and acoustical attenuation as required.
Hot water is generated using three natural gas fired 4-pass fire tube boilers. Each of these boilers is sized to handle approximately 50 percent of the total building heating load, and have peak efficiency of 82 percent. These boilers are designed to have the capability to operate using captured gas from a nearby landfill if that option becomes available in the future. Chilled water for the building is provided using water-cooled electric centrifugal water chillers and plate and frame heat exchangers.
Lighting:
Lighting for the exterior of the building and the surrounding area consists of streetscape style lighting to enhance the village concept of the area. Metal halide lighting poles and fluorescent light bollards provide lighting on all walking areas and ambient lighting on the building facades. Wall mounted fluorescent fixtures are located at main building entries.
Lighting in typical office and lab areas is provided by indirect or indirect/direct pendant luminaries with high output T-5, 3500 K fluorescent lamps. This provides a glare free work environment, increased perception of openness, and the potential for daylight harvesting. In high ceiling specialty labs where the level of illumination needs to be greater than that provided by the fluorescent lamps, 400-watt metal halide prismatic glass reflector fixtures are provided. Lobbies and other public areas use low voltage halogen lamps that provide accent and aesthetic warmth.
Electrical:
A single 13,800 volt, 3-phase, 3-wire, delta, 60 Hz primary feeder provides power from the transformer. This feeder is sized to handle the entire Visteon project electrical load and terminates into a 15kv main switchgear. The 15kv switchgear distributes the power from the primary feeder to three main electrical substations using Interlocked armored cables routed in overhead cable trays. The breakers for the feeders are insulated case type circuit breakers. The secondary power distribution system accommodates lighting loads, lab loads, mechanical equipment loads and other general loads. The building has a main power distribution switchboard, sized to handle the entire electrical load of the building. One 350kw and one 1000kw, 480Y/277 volt, 3-phase, 4-wire diesel generator will provide emergency power.
Power for all mechanical systems is 480 volt, 3-phase, 3-wire. Power for all receptacles and miscellaneous loads is 208Y/120 volt, 3-phase, 4-wire. Some specialty lab equipment has separate power requirements of 220 volt, 3-phase, 3-wire and 240 volt, 3-phase, 3-wire systems. For this specialty equipment, transformers and panel-boards are provided.
Additional Systems:
Vertical transportation will be provided by electric traction elevators that service all floors of the building except for the penthouse level, which must be reached using one of the many fire rated stairways throughout the building that service all floors. The telecommunication systems of the building consist of access control and closed circuit television, audio/visual devices, telephone system, and fire alarm system. The fire alarm system is monitored electronically and is also directly connected to the local fire authority to provide fast response in the event of an emergency.
