2 . The bridge lengths for each of the replacements will be customized to fit the specific <br /> sites. 5d' Street SW bridge is assumed to be no more than two spans, with a <br /> maximum span length of about 40 feet. Old Dixie Highway bridge and 43 `d Avenue <br /> bridge are assumed to be more than two spans with maximum span length of about <br /> 75 feet. <br /> 3 . Bridge plan geometrics and wingwall configurations will minimize the encroachment <br /> of the bridge ends into adjacent intersections and driveways. Wingwalls will also be <br /> set to allow for utility burial at the bridge ends. <br /> 4 . Slope protection, riprap and/or sheetpiles will be used at the bridge abutments to <br /> stabilize the canal banks in the vicinity of the bridges. <br /> 5 . It is anticipated that the COUNTY will allow road closures at all bridge locations <br /> such that phased construction will not be required. <br /> 6 . Utility coordination will be performed in order to evaluate existing utilities and <br /> accommodate utility crossings on the proposed bridges. <br /> 7 . The bridge design will be performed in accordance with the 1998 Edition of the <br /> AASHTO LRFD Design Specifications with Interim Revisions through 2002, and <br /> the 2002 FDOT Structures Design Guidelines, LRFD Edition . <br /> 8 . Construction and material specifications will be based on FDOT Standard <br /> Specifications for Road and Bridge Construction, 2000 Edition <br /> 9 . All design and plan details will be in the English unit system. <br /> 10 . 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 <br /> reviewed and approved by the COUNTY. Bridge 30% plan will include General <br /> Plan and Elevation views, Typical Sections and Notes. The 90% submittal will <br /> consist of Contract Plans and preliminary quantities and cost estimates . The 100% <br /> submittal will be the Final Plans, with Quantities, Opinion of Cost and <br /> Specifications. <br /> G. Construction Phase Services <br /> There are no construction phase services with this contract. <br /> SECTION IV - TIME FOR COMPLETION <br /> The time for completion of the 90% design drawings, permit applications, and Engineer ' s Opinion <br /> of Probable Construction Cost shall be twelve ( 12) months . Once permits are received, 100% design <br /> drawings shall be completed 90 days thereafter. <br /> 9 <br /> A:\BridgeDesign-ProfServicesAgreement-BridgeDesignAssoc.doc <br />
