Systems Information

Architecture:

This 25 story condominium complex was constructed using a steel frame structure which is contrary to the typical concrete structures used in residential high rises. The parallelogram shape that this building has assumed was dictated by the intersection of W. Erie St. and N. Kingsbury St. The unique shape and steel structure have allowed for very innovative and flexible floor plans. This structure also provides unobstructed floor to ceiling views of the great Chicago cityscape, and the stepping back of the upper floors allow for expansive terraces. The architecture is focused on images and views. The steel and glass façade with the large chevrons provide an image of modernity and make the structure seem light and graceful. The 30' lobby gives the image of the grand entrance. Even the interior décor of stainless steel appliances, granite counter tops, and European cabinets give a modern feeling to the individual units while the floor to ceiling windows and the steel braces frame spectacular views of the surrounding areas.

Structure:

The structural system employed by Erie on the Park begins with a foundation consisting of bell caissons that were drilled 85 feet to rest on soil with an allowable bearing pressure of 30,000 psf. Grade beams tie the tops of the caissons together to provide greater lateral stiffness to the foundation and to aid against uplift. The first three stories are two-way flat slabs supported against gravity loads by cast-in-place concrete columns and walls. At the third story the concrete columns transition to steel W-shapes. The fourth through sixth stories are 4" slabs on 3" metal decks that are partially composite with the beams and girders. Floors 7 through 25 are constructed of 2" concrete slabs on 14" deep open-web steel joists. The steel joists are in turn supported by steel W-shapes. The roof is 3" metal deck on W12 steel beams and girders.

The lateral system consists of 18 inch shear walls for the first 3 floors; two running North-South between the stair towers and the elevator core and three running East-West along the exterior of the building. These concrete shear walls transition to steel braced frames at the third floor which continue to the roof above the 25th floor. The steel braced frames are three story triangular braces that can be seen in the façade of the building.

Electrical:

The electricity for 'Erie on the Park' enters the building through four conduits from the city's power grid. One of the conduits goes through a metered switchboard that distributes power to the buildings common areas. This power is distributed through four separate panels to (1) the mechanical penthouse, (2) the two elevators, (3) the emergency lighting, and (4) the receptacles and lighting of the corridors and common areas. The second conduit enters an unmetered switchboard that distributes power to the different floors and through a 1600Amp busduct. At each of the floors this power is split and metered before it ultimately reaches each of the tenant units. The third of the four supply conduits is dedicated to the emergency lighting for the entire building, and the fourth supply is dedicated to the fire pump and controller. There is also a 450kW gas powered generator that in the event of a power outage would service the elevators, the emergency lighting, and the fire pump and controller.

Lighting:

The typical lighting scheme in 'Erie on the Park' is 6" recessed downlights in the public and private corridors on the tenant levels. The living rooms, kitchens and dining rooms of the tenant units have track lighting that range in length from 4' to 20', in increments of 4', depending on the size and layout of the condominium. The service areas and parking levels typically use 8' fluorescent strip lights. The lighting in the lobby and around the entrance incorporates more artistic lighting in the form of directional, accent and floor recessed lighting. The entrance to the building has recessed pathway lights that light your way into the lobby. There are also a number of accent lights that illuminate the shear wall that lines the entrance to the building. In the lobby there are directional and accent lights that add to the grandeur of the 30' ceiling.

Mechanical:

The mechanical system supply air is brought in at the 25th through two 4'x6' louvers to a pair of Carrier air handling units. Each AHU is capable of supplying 9,000 cfm each to the lower floors. Vertical fan coils to move conditioned air vertically between the 25 floors of this building. The air is distributed to each of the tenant rooms through 12 inch circular ducts. These ducts are suspended under the floor slabs by running through the openings in the open-web steel joists that support the floor slab. The ducts terminate at three foot linear distributors that are capable of 300 CFM.

Transportation:

There are two elevators that service the ground floor to the 24th floor.

Fire Protection:

The only information available about the fire protection is that the entire building is sprinklered.

Telecommunications:

Television and telephone services are provided in each of the units. There is an outlet for both services in each room of the residential units.

Special Systems:

As a security measure there is a 24 hour doorman.
