Architectural design and function
: |
The Building is a five-story apartment building that rests upon a two story parking structure; the first of witch is semi below grade. There is distinction from the parking garage to the apartment portion with a change in materials from brick to stucco. The noticeable voids in he exterior façade of the building is to create dimension between the high rising flat facades directly parallel to the building. This creates a more inviting space between the structures to house the merchants on the first floors. |

Building Envelope |
||
Exterior Wall Systems:
|
The Exterior Wall System is made of 8-14” hollow core CMU Units with Dur-O-Wal every other course and the cells that contain rebar grouted. A brick façade is located between the second level of the parking garage and the 1st finished floor. From level one to the roof, the exterior of the CMU’s have EIFS Stucco over 1 ¾” min. rigid insulation. On the Interior of the CMU’s are 2X metal studs at 16” O.C., 1 ½” rigid insulation, continuous water barrier, and ½” gypsum wallboard. |
|
Roofing Systems:
|
The roof is flat and framed with 8” deep concrete planks resting on a series of W14x34 and W12x26 beams plus the load bearing CMU exterior walls. Atop the Concrete planks rests a layer of Sure-Seal Insulation covered by a Sure-Seal/Brite-Ply EPDM Membrane. |

Structural System: |
The structural design is dominated by the load-bearing 8" CMU exterior walls that also cross north to south at particular portions in the interior of the building in order to be the primary lateral force resisting system. This system compliments the 8" pre-cast hollow core concrete slabs that make up at least 90% of all floor slabs in the building. The Interior slabs bear on the wide flange beam/column grid with W12X26 & W14X43 as the typical beam sizes. The majority of the steel columns carry the load to the parking levels where 20X24 concrete columns assist the load to the 6' X 8' concrete footing. | |
Mechanical System: |
The mechanical system in the Centre Court Apartments is gas fired with two 1800 CFM roof top units that process 360 CFM of outside air each. There is a 660 CFM Air Handling Unit located in the laundry area of the second and fourth levels. Each apartment is equipped with 5 in wall air-conditioning units. The units in the living rooms are 8000 BTU's and 840 cooling watts while the bedrooms units are 6000 BTU's with 600 cooling watts. | |
Lighting/Electrical: |
The Main wiring system is a 277/480 Volt, 3 Phase, 4 Watt system with an 85 W natural gas fired emergency generator with the same wiring. The ground floor electrical room contains a 150 KVA transformer with a 1600 AMP main switchboard. The lighting fixtures throughout the building are diverse with the majority of the exterior lighting supplied by Lithonia 50W-MH 120V wall mounted fixtures and the interior public lighting supplied by Lithonia 32W-T8 both wall and surface mounted fixtures. | |
Fire Protection: |
The Centre Court Apartments are fully sprinkled and all interior spaces are run off of a wet system while the two parking levels at the bottom of the building are run off a dry pipe sprinkling system. The fire service line extends from 5' outside of the west face of the building with a 6" pipe running directly into the Water Service Room on the ground level. | |
Construction: |
L.S. Fiore did The Construction in a design-bid-build process. The total project consisted of both a large renovation to the west end of a building to the north and the new construction of the Centre Court Apartment building atop a previous parking lot. | |
Transportation: |
There is an elevator located inside the main lobby toward the north of the building and there are two staircases, one located on the southeast corner of the building and the other in the south west that extend the full height of the structure. |
