Building Enclosure
The facade of the building has CMU base with a 1/2" UHPC panel for certain walls. The second type of wall is a prefinished aluminum composite panel that is fastened-over to semi-rigid mineral wool insulation. The aluminum curtain wall system runs a majority of the building. A fritted Kawneer, tpye 1600 wall system, can be seen at the main entrance of the Food Court as well as the second floor where the dining seats are located.
The roof just as the rest of the structural system in steel. The structural roof deck is a RD-1.5 metal decking with a depth of 1-1/2". An alternate to this roof deck system is a 1-1/2" acoustical roof deck. The roofing system for the Michigan Food Court consists of a membrane roofing ststem, which includes both ballast and extensive green roof tray system. The roof of the Food Court can be broken into two separate pieces as the roof is varies in different sections. In one are, a fully adhered roof membrane can be located with decorative river rock ballast. In the other section, a fully adhered roofin membrane with an extensive freen roof try system can be located ( further discussed below as part of a sustainable feature.) The roof starts with a 1-1/2" roof deck that lies below a 1/2" substrate board that has a vapor retarder adhered to it. Next lies the continuous R-24 roofing insulation before reaching a cover board. AFter the cover board comes a drainage panel with fully adhered membrane of roofing coming next. The last piece of the roof as stated earlier varies in areas and will either be a layer of river rock ballast or an extensive green roof tray system.
Sustainability Features
The Michigan Food Court contains signifcant sustainability features as this building is intended to achieve LLED silver. The main sustainable feature that was implemeneted was the rain garden. The rain garden on the rood was designed to capture rain that could then be recirculated for pre-rinse and save about 85% of the water usage for he Food Court. The Food Court was designed to implement Var-Flow Controls, which has turndown capabilities on both exhaust and temepered make-up air of up to 50%, this results in 90% of electrical savings and additional heating and cooling savings. Using Vari-Flow controls contributes to earning two LEED credits. Additionally, components of being sustainable is the use of an air economizer within the air handling units. In an open space that adjacent to the building, a vegetated open space will be provided for the use of the public.
Construction
The Michigan Food Court is a project that is to be constructed within a one year time span. With the Michigan Food Court estimated to be around $34 million, the projcect will start in the Fall 2016 with completion estimated to be Winter 2017. The biggest concern that the building construction team will face will be the weather conditions of the Michigan region during the winter months. The soil and civil work will pose a challenge during the steel erection.
Mechanical
The Michigan Food Court contains an on site plant that supplies steam to 5 shell and tube heat exchangers:
- 2 are used for domestic hot water of the building
- 1 for the perimeter fin tube radiation of the building
- 2 for the snow melt system that is outside of the building used for the walkways.
The chilled water of the building is provided by 2 air-cooled water chillers: one at 225 tons and the other 280 tons. Theses two chillers sit outside in a nearby chiller yard.
There are 4 air handling units that were placded into the mechanical room of the building on the first floor. 3 air handling units supply 100% outside air while the other air handling unit is running make up air to the supply ducts.
Each kitchen grill has its own fan hood that exhausts the air straight out of the building. Any air that can be constituted as make up air from the dining area is reused within the building.
Electrical/Lighting
The Michigan Food Court has a 100% LED lighting system is utilized, helping to lower energy consumption and contribute to its sustainability. The building is powered from a 300kVA transformer, and a 500 amp, 3 wire, 480 V primary feeder. The building also has a 438 kVA natural gas emergency generator and draws power from several substations for quality assurance.
Structural
The Michigan Food Court is a non-composite structural steel system with HSS columns. The framing of the Food Court consists of both moment and braceing frames. For the concrete foundation, the minimum allowable bearing capacity for spread footings and continuous footings are 3000 PSF for both. The concrete used for slab-on-grade and and on metal decking is to a have a compressive strength of 4000 PSI. The steel floor decking is to be 3 inches deep composite floor decking with a design thickness of 0.0358 inch fabricated zinc coated steel sheets complying with ASTM A 653 SS, G60 coating designation. DEcking will be installed in 3 span lengths.
Fire Protection
The Michigan Food Court abides by codes set forth by the NFPA. All spaces which are classified as class A-2 spaces are fully sprinklered. 100% automatic sprinklers will be provided throughout the whole building. Dry-type sprinkler heads will be placed in the walk-in freezer/cooler, while the sprinkler heads in all other areas will be coordinated with all trades.
Plumbing
The Michigan Food Court is in accordance with the 2009 Michigan Plumbing Code. The gray water that is used within the building comes from the captured rain water on the roof.
Transportation
The Food Court has multiple entraces to the building for those entering the first level looking to go to the cafe and an entrance on the second level for those looking to have a meal from one of the several food locations. Once inside the building, one can take the stairs on the inside either up or down or for those that are handicap, 2 elevators are available to use. A stairway outside also leader for the first level to second level with an overhang to protect against the environment. The outside stairs as well as landings are heated by the snowmelt system.
Telecommunication
The Food Court's has two telecommunication rooms, one on each floor with the telecomunication lines within the building running through the first and second floors. The PA systems are on both floors for all to hear. As well as PA systems, the Food Court has telephone lines and that run both levels of the building. Wireless internet is also provided throughout the bulding.
