Amazon Park (Zig-Zag) Bridge <br /> . OBEC Proposal No. 089P23 <br /> Dear Emily: <br /> OBEC Consulting Engineers, in association with Foundation Engineering, Inc. (FEI), is pleased to <br /> present this proposal for engineering services to the City of Eugene for the proposed Zig-Zag Bridge <br /> located in Amazon Pazk. Following is OBEC's understanding of the scope of work for the bridge <br /> the City desires to build. <br /> PROJECT UNDERSTANDING <br /> The City of Eugene is currently in the planning process for extensive improvements to Amazon <br /> Park. The project is part of a city-wide park improvement bond levy measure that passed several <br /> years ago. The proposed improvements at Amazon Park include the bridge as asite-specific <br /> sculpture and a functional pedestrian bridge crossing Amazon Creek. The Zig-Zag fridge is <br /> proposed ~to meet project requirements for the 1 percent for art program and provide a pedestrian <br /> bridge across the Amazon Creek approximately midway between 29th and 24th avenues. <br /> The art bridge has been conceptualized by Lee C. Imonen, asite-specific sculpture artist and <br /> instructor at Lane Community College. The City provided OBEC with schematic design plans for <br /> the bridge, photos of a scale model of the bridge, a park improvements concept design, and a <br /> preliminary site survey. In addition, OBEC met with you and Carolyn Weiss on site to discuss the <br /> proposed bridge project. <br /> Lee's design consists of a structural steel bridge that is sinuous in plan view (hence the name Zig- <br /> Zag Bridge), on four (4) piers below deck that develop into sculpture ornament above deck. The <br /> deck consists of timber, and the rails consist of steel tubes and galvanized wire. The span <br /> arrangement is approximately 3'-18'-18'-18'-3' for an overall bridge length of 60 feet. From the <br /> conceptual plans the bridge raises approximately 30 inches and meets current ADA requirements. <br /> OBEC has reviewed the plans and find them to be conceptually sound. It is our understanding that <br /> SALEM EUGENE -Corporate Office MEDFORD <br /> (503? 589-4100 1541? 683-6090 {541) 774-55910 <br /> FAX (503) 589-4141 FAX (541) 683-6576 FAX 1541) 774-5591 <br /> <br /> 2235 Mission Street SE, Suite 100 920 Country Club Road, Suite 1006 1335 Poplar Drive <br /> <br /> Salem, Oregon 97302-1295 Eugene, Oregon 97401-6089 Medford, Oregon 97504-5207 <br /> www.cbec.com <br /> <br />
