The elevated Morgan Street Station in Chicago contains 12,500 square feet that defi nes the Fulton Market District. Owned by the Chicago Department of Transporta- tion, Chicago, and designed by Ross Barney Architects, Chicago, the choice was made to use steel the predominant material for its combination of high strength, high- recycled content, regional availability and fabrication, durability and ability to provide weather, salt and abuse-resistant fi nishes. 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 sub-
contractors. Western Remac, Woodridge, Ill., installed the structural steel transit panels. U.S. Architectural Glass & Metal in Darien, Ill., in- stalled the perforated panels, guardrails, hand- rails, glazed window wall system, stairs and decking. and Tefft Bridge & Iron Inc., Wheat- fi eld, 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 fl ashing and gutters. Cabworks LLC, Frank- lin 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, in-
Metal defi nes and distinguishes busy metropolitan railway station
stalled the steel doors. Lockport Steel Fabrica- tors, Lockport, Ill., and Binzel Industries, Rolling Meadows, Ill., fabricated most of the miscel- laneous and architectural metals. For the station, track, canopy and bridge
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 fi nish, 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 fi nish 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 sup- port system and features stair stringers, lintels at masonry openings and stair roof support framing. One thousand square feet of galva- nized steel was used for stair enclosures, while cast iron was used for the stair treads. Due to the fact there is not a defi ned build-
ing envelope, sustainable strategies for the project concentrated primarily on materials and resources. Steel and concrete are the pre- dominantly 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 fl ooring was extracted from regional quarries; and glazing was regionally produced. The proj- ect landscaping is drought tolerant and requires no irrigation. New bicycle racks encourage the use of alternative transportation.
