Building Statistics, Part II
Electrical System 
The Hall Corporate Headquarters is supplied electrical service by Dominion Virginia Power. The incoming secondary is 480/277 V serving an 800 amp (MDP) Main Distribution Panel. The wiring system used is a 3 phase, 4 wire configuration. The Main Distribution Panel is rated at 25 KAIC. The wiring will mainly be THHW and THHN. The MDP serves the 480/277 V panelboards on the first, second and third floors. The 480/277 V panels serve 3 transformers one on each floor that step down the voltage to 208/120 V. The transformers used in the building are listed as follows. The first floor transformer is 75 KVA, 3 Phase, 480-208/120 V, K-4 rated and is floor mounted. The second floor transformer is 45 KVA, 3 Phase, 480-208/120 V, K-4 rated and is floor mounted. The first floor transformer is 75 KVA, 3 Phase, 480-208/120 V, K-4 rated and is floor mounted. There are 3 panels run on 408/277 V and 7 panels run on 208/120 V for a total of 10 panels used in the buildings. The 208/120 V panels are mainly used for power to receptacles and other objects in the building.
Lighting System 
The lighting in the Hall Corporate Headquarters is run mainly on 277 V. A small amount of the lighting is run on 120 V only 3 of the 25 fixtures used in the building are run on 120 V. The lighting includes very general lighting used in buildings with an office type setting. The fixture schedule for the Hall Corporate Headquarters can be located on my website as a separate file under the technical assignment link.
Typical 2’ X 2’ parabolic troffer fixtures are located in the meeting rooms, private offices and open office spaces. Downlights are used throughout the building to add to the light given by the parabolic troffers in certain areas. Recessed 1’x 4’ troffers are used for the lighting in the restrooms. The lobby is mainly lit with pendant and recessed downlights. Wall sconces are also used to light the lobby. The exterior is lit with vertically mounted wall washers and flood lamps directed towards the buildings facade. The parking lot is lit using 17 pole mounted exterior fixtures. The buildings side and rear façade is lit with 14 vertically wall washers. The front façade is lit with 4-100W metal halide flood lamps and the entry canopy is lit with 2-2 lamp 42W CFL recessed downlights.
Mechanical System 
The mechanical system in the Hall Corporate Headquarters is a Variable Air Volume (VAV) system with electric reheat. There are two Roof Top Units (RTU) and two Air-Cooled Condensing Units (ACCU) used in the mechanical system. The RTU’s are supplied by a 460 V, 3 phase power source. The fan powered VAV terminals for RTU-1 range from 280 cfm to 778 cfm. The fan powered VAV terminals for RTU-2 range from 185 cfm to 1308 cfm. There are two Fan Coil Units (FCU) sized at 12.6 mbh and 8.2 mbh. The 12.6 mbh FCU is powered by a 208 V, single phase source and the 8.2 mbh FCU is powered by a 115 V, single phase source. The mechanical system is monitored by the buildings EMCS system. Individual controls that the occupants can change are located throughout the building. The system has direct expansion refrigeration with output ranging from 422 –565.2 mbh.
Structural System 
The structural
system in the Hall Corporate
Headquarters is made up of the following. The skeleton is constructed of
tubular steel columns, steel wide flanged beams and steel joists. The floor is
concrete slab over non-composite metal deck. The ground floor is concrete
slab-on-grade. The ground slab is supported concrete pile caps on driven
concrete piles. The façade of the building is constructed of brick. The
entrance canopy to the building is constructed of steel beams.
Fire Protection 
The fire
protection system in the Hall Corporate
Headquarters is made up of the following components. The building sprinkler
system provides full coverage for the building per NFPA-13. The structural
systems beams, columns and joists are rated at 1 hour fire protection. The
building is classified under use group “B” which is Business. This class of use
group does not allow the use of construction materials less then 2C
noncombustible unprotected rating. The exit enclosures, shafts, hoists, smoke
partition and horizontal enclosure beneath shafts have a 1 hour protection
rating.
Transportation 
The Hall Corporate Headquarters has
one elevator located to the left of the lobby as you enter the building. The
building is only three stories high so stairs are the main source of getting
