Building System Information:
Architecture:
The Residences of Sherman Plaza are located in the diverse community of downtown Evanston, IL, just north of the city of Chicago on Lake Michigan. The 25 story condominium is the second tallest building in Evanston and offers residents luxuries that were once only available in downtown Chicago, such as a 54,000 square foot health club, garage parking, ½ acre rooftop garden, and easy access to the El and Metra trains.
The condominium is located on a site that was originally a parking garage with 566 spaces. The new construction will house 253 condominiums, lofts and penthouse residences, 152,000 square feet of retail space, and a new adjoining 1,585 car parking garage. The retail spaces are located on the first two floors and are occupied by retail tenants, such as Barnes & Noble Booksellers, Pier 1 Imports, and Washington Mutual. Residents can choose from a one bedroom condominium, a two bedroom loft, or a 2-4 bedroom penthouse suite with private terrace.

The building is zoned in the Downtown Retail/Development Core in Evanston, IL. There are no historical requirements.

Building Envelope:
The walls of the bottom two retail floors are covered in hard fired natural clay face brick with an encircling three foot base made of precast panels and granite. There is also limestone and cast stone detailing on the first two floors. The face brick continues up to the seventh residential floor and the rest of the walls are primarily smooth formed concrete.
The roofs of the third, sixth and seventh stories are covered with an intensive roof garden as the building steps back. This green roof is comprised of layers of intensive soil, filter fabric, drainage/water retention channel elements, and prefabricated drainage courses. The top three penthouse floors have cast-in-place concrete eyebrow roofs and are covered with a single-ply elastomeric EPDM fully adhered roofing system above 2 inch roof insulation.
Construction:
The site of the Sherman Plaza condominiums was previously a large parking garage. Demolition of the site began in April 2004. The city of Evanston has zoned the area as a “Downtown Retail/Development Core”, which therefore poses no problems for the construction of this building. Construction began in December 2004 and is expected to be finished in April 2006. The project delivery method was design-bid-build.
Structural:
The structural system for the Sherman Plaza residential tower consists of reinforced cast-in-place concrete columns, shear walls, slabs and beams. A typical floor slab for both the lower retail floors and the upper residential stories is 8 inch thick two-way reinforced concrete slab. The column sizes range from a 36”x36” square column at the ground floor to a 20”x20” square column at the roof level. ACI 318-83 was the primary design code used for the structural concrete design.
The lateral loads are resisted by reinforced concrete shear walls, including the elevator core walls, in both the North-South and East-West directions. Lateral loads are also resisted by perimeter moment frames. ASCE 7-98 was the primary design code for lateral loads.
A portion of the lower two story retail building was designed in structural steel. The floor framing is standard rolled structural steel shapes that act compositely with the floor slabs. This composite system provides for additional stiffness and strength. The floor slabs are formed by concrete topping on steel deck, making a composite steel deck slab. Columns are also structural steel. The building is supported by a foundation of belled caissons that extend to hardpan at approximately 70 feet below grade, with an allowable bearing pressure of 30 ksf.
Electrical:
Sherman Plaza’s electrical system is powered by a 480/277 Volt and a 208/120 Volt system. The 480V transformer provides power primarily to the cooling tower and mechanical system. The 208/120V, 3 phase-4 wire voltage system is used to power the rest of the building.
Lighting:
The lighting in Sherman Plaza is primarily standard fluorescent lighting. Accent wall sconces are used in the units’ entryways and bathrooms. The roof gardens have extra lighting features with plant up-lighting, landscape, patio and bollard lighting. The bottom retail floor has surface mounted exterior light fixtures in between storefront windows.
Mechanical:
The primary mechanical equipment for Sherman Plaza is located in the 3rd floor and 26th floor mechanical equipment rooms. A cooling tower plant and two chillers are located on the second story roof of the retail building and are sized to service all 25 stories, including the retail area. Air handling units at 40,000 CFM are located in the 3rd floor mechanical room with another smaller air handling unit servicing the lobby at 2,500 CFM. Each of the lofts, condominiums, and penthouses has an individually controlled in-unit electric heat and air conditioning unit. Each of the residences has a fan coil unit with electrical heating with standard ducts. Exhaust fans in the 26th floor mechanical room provide exhausts for the kitchens, toilets, and in-unit dryers.
Fire Protection:
Sherman Plaza follows the 1996 BOCA National Fire Protection Code. Exterior bearing walls and interior columns have a 3 hour fire resistive rating. Stair and shaft enclosures and floor construction have a 2 hour rating, and dwelling unit separations and exit corridors have a 1 hour fire rating. The building contains a state-of-the-art fire alarm and sprinkler system, as well as basic fire suppression materials.
Transportation:
The building is served by three elevators: two passenger and one freight elevator. The passenger elevators are hydraulic type with a 2500 lb. capacity and a speed of 125 feet per minute. The freight elevator is an electric traction type with a 5000 lb. capacity and a speed of 500 feet per minute. A set of escalators serve the first two floors in the retail area. The escalator is a clat-step reversible type for ascending and descending passenger service with a speed of 100 feet per minute.
