Exhibit B -Scope of Work <br /> Contract 2006-00229 <br /> March 2, 2006 <br /> Steve Gallup, P.E. <br /> City of Eugene <br /> Public Works Engineering <br /> 858 Peari Street <br /> Eugene, OR 97401 <br /> RE: Golden Gardens Bridge over A-2 Channel <br /> OBEC ]ob No. 89-80 <br /> Dear Steve: <br /> OBEC Consulting Engineers is pleased to present this proposal for engineering services to the Gty <br /> of Eugene for the proposed Golden Gardens Bridge over the A-2 Drainage Channel. The following <br /> is OBEC's understanding of the scope of work for the bridge the City desires to have designed and <br /> built. <br /> PRO.7ECT UNDERSTANDING ~ <br /> The City of Eugene is currently in the process of planning a bridge over the A-2 Drainage Channel <br /> in Golden Gardens Park just north of Jessen and Golden Gardens streets to provide emergency <br /> access to the park. OBEC met with you on-site to discuss the proposed bridge project, project <br /> limits, and roadway required. <br /> It is our understanding that the City will investigate and acquire the appropriate permits, <br /> endangered spedes survey, wetland delineation, archaeological field survey, construction <br /> easements, and right-of-way needs and utility coordination. Presently, no easements or right-of- <br /> way needs are anticipated. We do not antidpate any monumentation will be disturbed and, <br /> therefore, a recovery survey will not have to be filed with the County. OBC-C is prepared to provide <br /> the necessary surveying, hydraulics analysis and bridge design (induding the gravel connection <br /> road and restriction gate). OBEC understands that the City wants us also to perform specific <br /> construction engineering services but that those services will be contracted later in the project <br /> because of City budgetary issues. <br /> At this time the bridge is anticipated to be apile-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). We anticipate that <br /> the bridge will not require approach guardrails due to its very low volume and restricted access. <br /> <br /> Chevron boards or reflectors on the bridge comers and a restrictive posting "closed to public <br /> access" may be appropriate. <br /> <br />
