i <br />F. Structural Plans <br />The Consultant shall prepare preliminary and final bridge plans for the demolition and <br />replacement of bridges on Oslo Road as detailed below: <br />Bride Section <br />Lateral "J" 5 -Lane <br />Lateral "C" 5 -Lane <br />1. The proposed typical section will be similar to the section designed for the Oslo Road <br />bridge over the Lateral B canal, which includes five lanes, 8 ft. sidewalk on the north side <br />only, and utility shelves on both sides of each bridge, with an estimated overall width of <br />88'-6". <br />2. The bridge lengths for each of the replacements will be customized to fit the specific <br />sites. Both bridges are assumed to be no more than two spans, with a maximum span <br />length of about 40 feet. <br />3. Bridge plan geometrics and wingwall configurations will minimize the encroachment of <br />the bridge ends into adjacent intersections and driveways. Wingwalls will also be set to <br />allow for utility burial at the bridge ends. <br />4. Slope protection, rip -rap and/or sheetpiles will be used at the bridge abutments to <br />stabilize the canal banks in the vicinity of the bridges. <br />5. Both of these bridges will be phase constructed in order to maintain traffic on the existing <br />structures during the construction of the replacement bridges. <br />6. The bridge design will be performed in accordance with the 1996 Edition of the <br />AASHTO Standard Specifications for Highway Bridges, and the 1987 FDOT Structures <br />Design Guidelines, Revision H. <br />7. Construction and material specifications will be based on FDOT Standard Specifications <br />for Road and Bridge Construction, 1991 Edition with published 1994 Supplements. <br />8. All design and plan details will be in the English unit system. <br />9. Bridge plan submittals are anticipated at the 30%, 90%, and 100% stages. The 30% <br />submittal will occur after the 30% roadway and intersection geometry has been reviewed <br />and approved by the County. Bridge 30% plans will include General Plan and Elevation <br />views, Typical Sections and Notes. The 90% submittal will consist of Contract Plans and <br />preliminary quantities and cost estimates. The 100% submittal will be the Final Plans, <br />with Quantities, Opinion of Cost and Specifications. <br />G. Certification <br />1. Certification will be made to St. Johns River Water Management District based on <br />AsBuilt data provided by Indian River County. <br />7 <br />
