CITY OF EUGENE CONTRACT #2006-00229 <br /> Amendment One <br /> Exhibit A-Page One of Three <br /> June 6, 2006 <br /> <br /> .~Q~i.~ev-V~lilier <br /> ~teve-6aNup, P.E. <br /> City of Eugene <br /> Public Works Engineering <br /> 858 Pearl Street <br /> Eugene, OR 97401 <br /> RE: Goiden Gardens Bridge over A-2 Channel <br /> Amendment for Construction Engineering Services <br /> OBEC Job No. 89-80 <br /> Dear Steve: <br /> OBEC Consulting Engineers is pleased to present this proposal for construction engineering services <br /> to the City of Eugene for the proposed Golden Gardens Bridge over the A-2 Drainage Channel, The <br /> following is OBEC's understanding of the scope of work for the bridge the City desires to have <br /> designed and built. y <br /> PROJECT UNDERSTANDING <br /> The City of Eugene is currently in the process of planning to construct a bridge over the A-2 <br /> Drainage Channel in Golden Gardens Park just north of Jessen and Goiden Gardens streets to <br /> provide emergency access to the park. <br /> It is our understanding that the City will investigate and acquire the appropriate permits, <br /> endangered species survey, wetland delineation, archaeological field survey, construction <br /> easements, and right-of-way needs and utility coordination. OBEC is prepared to provide the <br /> necessary construction engineering services. <br /> At this time the bridge is anticipated to be agile-supported prestressed precast slab bridge <br /> approximately 70 feet long with pedestrian height guardrails/vehide barrier. Pile foundations are <br /> preferred for their high vertical and lateral capacity, resistance to scour, and low disturbance below <br /> grade (minimizing environmental impacts and associated permitting actions). The bridge will not <br /> require approach guardrails due to its very low volume and restricted access. <br /> <br />
