Morgan Street Station in Chicago

morgan_street_stationThe elevated Morgan Street Station in Chicago contains 12,500 square feet that defines the Fulton Market District. Owned by the Chicago Department of Transportation, Chicago, and designed by Ross Barney Architects, Chicago, the choice was made to use steel the predominant material for its combination of high strength, highrecycled content, regional availability and fabrication, durability and ability to provide weather, salt and abuse-resistant finishes. F.H. Paschen, S.N. Nielsen & Associates Inc., Chicago, was the general contractor. TransSystems, Chicago, was the structural as well as civil engineer for the project and the prime consultant.

The large project included a variety of subcontractors. Western Remac, Woodridge, Ill., installed the structural steel transit panels. U.S. Architectural Glass & Metal in Darien, Ill., installed the perforated panels, guardrails, handrails, glazed window wall system, stairs and decking. and Tefft Bridge & Iron Inc., Wheatfield, Ind., furnished the structural steel and W.E.B. Production and Fabricating, Chicago, installed the structural steel. Whited Brothers Inc., South Holland, Ill., fabricated and installed the flashing and gutters. Cabworks LLC, Franklin Park, Ill., installed the customer assistance kiosks. Boom Edam Tomsed, Lillington, N.C., fabricated the rotogates, while Hayward Baker, Roselle, Ill., was responsible for the micropiles. Precision Metals
& Hardware, Milwaukee, installed the steel doors. Lockport Steel Fabricators, Lockport, Ill., and Binzel Industries, Rolling Meadows, Ill., fabricated most of the miscellaneous and architectural metals.

For the station, track, canopy and bridge morgan_street_station_two superstructure, 1.25 million pounds of painted structural steel was used. The platform and stair guardrails feature 5,000 square feet of Type 304 stainless steel with a #4 finish, as do the 1,500 square feet of handrails, 3,500 square feet of ceiling and wall panels, six benches, two customer assistant kiosks, two rotogates and other miscellaneous metals within the public areas. Type 316 stainless steel with a #4 finish was used for 12,000 square feet of perforated panel cladding and support systems. Hot dip galvanized steel was used for 1,200 feet of canopy purlins, gutters, downspouts and windbreaks. In addition, 5,700 square feet of glazed area holds a glazing support system and features stair stringers, lintels at masonry openings and stair roof support framing. One thousand square feet of galvanized steel was used for stair enclosures, while cast iron was used for the stair treads.

Due to the fact there is not a defined building envelope, sustainable strategies for the project concentrated primarily on materials and resources. Steel and concrete are the predominantly used materials, each of which are made up of high amounts of recycled content. Polycarbonate panels have both a high recycled content and are regionally produced; granite flooring was extracted from regional quarries; and glazing was regionally produced. The project landscaping is drought tolerant and requires no irrigation. New bicycle racks encourage the use of alternative transportation.
