1.6 TASK 4 -INTERMEDIATE DESIGN The Engineer will: 1.6.1 Prepare an intermediate design plan and supporting documents for the Project, including plan and profile, in sufficient detail to indicate clearly the problems involved including approximate locations of the existing utilities within the Project site or right-of--way and anticipate the design, if appropriate, of solutions to minimize conflicts. 1.6.2 Show on the plan existing topographical features including improvements within and outside the right-of--way necessary for the design of the Project. Also show any fence or structural encroachments, and identify whether or not removal is necessary for construction and/or utility relocation. 1.6.3 When applicable, show adequate existing property-line elevations, proposed top-of--curb elevations, proposed top-of-channel elevations and adequate proposed flow-line elevations on the profiles. 1.6.4 Under separate cover, submit one set of hydrological and hydraulic calculations to support the proposed drainage design. Also plot and submit the energy lines and hydraulic grade lines on one set of prints for review by the City. 1.6.5 When both drainage and street reconstruction are included in the Project, show the proposed drainage facilities and street improvements on the same plan and profile sheets. 1.6.6 Include street and drainage cross sections for every fifty-foot station (plus any intermediate stations if field conditions so dictate) at a scale of 1" = 40'-0" horizontally and 1" _ 10'-0" vertically unless otherwise directed by the City. These designs will combine the application of sound engineering principles with a high degree of economy. Design standards of other agencies, when approved by City, will be used when so directed by the City's Project Manager. 1.6.7 Unless directed otherwise by the City, provide drawings that include, but are not limited to plan and profile sheets with the plan portion at a scale of 1" = 40' - 0" and the profile portion at a scale of 1" = 40'-0" horizontally and 1" = 10'-0" vertically. All scales should be conveniently located on each sheet and have the scaled number ratios on corresponding horizontal or vertical scales readily noticeable. All drawings will be submitted on standard 11" by 17" sheets (untrimmed). 1.6.8 Furnish a cost estimate based on the plan and supporting documents of the proposed construction (excluding land costs). The cost estimate will be based on the latest unit prices for similar work as provided by the Engineer. The City will assist in providing unit prices and approve any adjustments to reflect the ease or difficulty of constructing the Project. ~~IB;e.iS'x6; 1c,£'4Slaa~ii 6
