C -- NOTICE FOR STATEMENT OF INTEREST FOR HIGHWAY BRIDGE DESIGN PROJECT SOL NH 0016(34)11 DUE 021497 POC Point of Contact -- John Cole, Chief Bridge Engineer, SDDOT, 605-773-3285 The South Dakota Department of Transportation (SDDOT) is soliciting Statements of Interest from consulting engineering firms for the design of a US Highway 16 bridge to span Hell Canyon approximately 20.9 km east of the Wyoming State line in Custer County, South Dakota. This project is federally funded through the Federal Highway Administration. The proposed bridge location is on a new alignment of US Highway 16 crossing picturesque Hell Canyon near Jewel Cave National Monument in the Black Hills of South Dakota. The proposed alignment locates the two lane (12 m width) roadway bridge deck approximately 112 m above the canyon floor and requires the structure to span approximately 640 m across the canyon. There will be separate grading, bridge and surfacing projects to complete this 9.5 km segment of highway. This Statement of Interest is for the bridge project only, and includes preliminary engineering and plans preparation. Currently, the bridge project is programmed for early FY 2000. The SDDOT will be responsible for field survey, geotechnical investigation and environmental studies. The Consultant will be required to provide the following engineering services: Phase 1 -- Bridge type study including preliminary designs, layouts and cost estimates for alternate structure types to allow a comprehensive evaluation of alternatives with respect to economy, aesthetics and impact to the site. Phase 2 -- Final design and plans preparation for the selected alternative. This is a request for Statements of Interest only. The SDDOT requires that the Consultant submit a copy of a current GSA Standard Form 255. In addition, the consultant must include information that describes the firm's previous experience with similar projects, particularly long span high profile type structures in environmentally sensitive locations. Identification of the proposed design team members, including specific team member experience with projects of this type, is helpful. A minimum of two equally qualified bridgedesign engineers is required for SDDOT bridge design. SDDOT will invite proposals from a short list of those responding to this Statement of Interest that appear to be the most qualified. The firm selected from the short list shall have a Certificate of Authorization to practice engineering in the State of South Dakota at the time of contract signing. The SDDOT will afford equal opportunity to all those who submit Statements of Interest and will not discriminate in its selection on the grounds of race, sex, color or national origin. (0015)
