Your Steel Bridge Specialists Patrick Allen Adam Ziegler Eric Beier Amanda Stevens RHIT Civil Eng., 5500 Wabash Ave., Terre Haute, IN 47803 December 20, 2002 Ted Hazledine, President Benchmark Fabricated Steel 4149 Fourth Park Way Terre Haute, IN 47804 Dear Mr. Hazledine: We, the engineers at Tacoma Design Company, are excited to be involved with the design and construction of a steel bridge for the ASCE/AISC Steel Bridge Competition. We have considered several design options including cable-stayed, cantilever, suspension, and truss types. We have chosen a design for our bridge and are in the process of designing connections and continuing fabrication. This progress report includes pertinent information such as a description of the competition constraints and Tacoma Design Company’s project approach for producing a competitive bridge. The enclosed progress report outlines Tacoma’s progress to date as well as the items to be completed. It includes all initial design options, advantages and disadvantages of each preliminary design, and a comparison analysis of the predicted deflections. We appreciate your time and commitment to this project. We encourage you to continue to contact us with any questions, comments, or feedback throughout the duration of this project.

Bridge No. 1 Design and Construction Details1.0 Project Description - 1 - Patrick Allen Adam Ziegler Eric Beier Amanda Stevens RHIT Civil Eng., 5500 Wabash Ave., Terre Haute, IN 47803 The American Institute of Steel Construction (AISC), founded in 1921, is a not-for-profit technical institute and trade association whose goal is to serve the structural steel design community. The mission of AISC is “to advance the position of structural steel as a building material by being the leader in steel related technical and market building activities.” AISC has a tradition of more than 80 years of service to the steel construction industry worldwide, providing all the experience and skill needed to make structural steel the material of choice. The American Society of Civil Engineers (ASCE), founded in 1852, celebrates 150 years of service this year. The mission of ASCE is to advance the position of civil engineering in the United States. It offers a wide variety of resources to its members including continuing education materials, conferences, and community events. The AISC, in conjunction with the ASCE and several other co-sponsors, hosts an annual steel bridge competition for civil engineering college students in the United States. The competition is widely regarded as one of the most competitive engineering student competitions in the country. It requires students to design and construct a steel bridge to compete in several categories including stiffness, lightness, construction speed, aesthetics, efficiency, and economy. The competition requirements are changed each year to promote new and creative designs. There are two levels of competition; regional and national. The regional competition serves as an elimination round for national competition. The problem statement given by the competition rules is to build a replacement bridge for an environmentally sensitive river in a short amount of time. Furthermore, the Department of Transportation has required steel as the construction material, and the new bridge must reuse modular decking from an older bridge. Construction is limited by such things as soil conditions, which restrict the weight carried by individual cranes (student builders), and the environmentally sensitive river, which prohibits bridge piers in the river. The1.0 Project Description - 2 - Patrick Allen Adam Ziegler Eric Beier Amanda Stevens RHIT Civil Eng., 5500 Wabash Ave., Terre Haute, IN 47803 piers must be built on the banks and the natural island. The Department of Transportation requests submittals of 1/10th scale models of the proposed design concepts. The models will be constructed under simulated conditions, load tested, and judged for the qualities mentioned above in order to determine the winning design. Benchmark Fabricated Steel, is a full-service fabricator and distributor of structural steel, miscellaneous metals, and related products, located in Terre Haute, Indiana. Benchmark has been certified by the American Institute of Steel Construction Quality Certification Program for Conventional Steel Structures and Complex Steel Building Structures.
