Mr. Steve Gallup <br /> February 1, 2006 _ <br /> Page 3 <br /> Preliminary Bridge Design: This task includes preliminary sizing of structural members and <br /> related details of foundation, superstructure, railing, abutments, gravel connecting road, and <br /> gate. OBEC will be sizing the bridge foundation piling based on an assumption of similar <br /> subsurface conditions to other bridges in the area that we have experience with and their actual <br /> as-built information. We do not anticipate needing a geotechnical consultant for this project. <br /> Preliminary Design Memorandum: This task includes preparation of a preliminary design memo <br /> report including preliminary drawings for Golden Gardens Bridge, construction and <br /> constructability issues and review, and a preliminary construction cost estimate. The <br /> information and design drawings contained in this memo can be used to facilitate any <br /> environmental, floodplain, and stormwater permits. <br /> TASK 4 -FINAL DESIGN, PLANS & SPECIFICATIONS <br /> This task includes final bridge design and the preparation of detailed plans and specifications for <br /> City bidding. All bridge design will conform to the Oregon Department of Transportation <br /> (ODOT) and American Public Works Association (APWA) Oregon Standard Speclflcadons for <br /> Consirucdon, ODOTs Bridge Design and OraRing Manual, AASHTO LRFD Bridge Design <br /> Specification, and. City of Eugene Public Works Standards as applicable. <br /> This phase includes the following engineering services: <br /> ¦ Provide Advance (95 percent) plan drawings including bridge plans and required details, <br /> standard drawings, and other related drawings for submittal to City for review as applicable. <br /> This will include a cover sheet, erosion control sheet and traffic control sheets as applicable. v,i~fr <br /> ¦ Advance Plan corrections as required. All plans will be drafted in English units in AutoCAD <br /> 2002 format. It is our understanding that the plans do not have to meet.City of Eugene <br /> standard practices for fonts, layers, etc. <br /> ¦ Prepare draft and final technical specifications and special provisions. <br /> ¦ Perform independent design check and QA/QC plan review of all drawings and related <br /> quantities. <br /> ¦ Calculate final structure quantities and prepare final estimate of construction costs. <br /> ¦ Furnish final half-size plans, specifications, and estimate (PS&E) for City bidding of project. <br /> ¦ Assist the City in the bidding by answering questions, addendum preparation, etc. <br /> ¦ Provide Plans and Calculations stamped by a Professional Engineer to the City for obtaining <br /> a Building Permit <br /> At this time it is assumed that the City will prepare and collate contract documents including <br /> OBEC-prepared work. It is assumed that the City will print, advertise, and bid the project. <br /> ESTIMATED FEE <br /> <br /> The attached spreadsheet indicates the anticipated hours and associated fee required to complete <br /> <br /> the tasks as outlined above. At this time OBEC proposes to perform the work on atime-and- <br /> material-basis not-to-exceed $31,000 as shown on the fee spreadsheet. Rates are based on <br /> <br /> OBEC's current Cty of Eugene Personal Services Contract for Architecture and Engineering. <br /> ESTIMATED CONSTRUCTION COST <br /> <br />
