• Topographic Base Map Preparation a. Utilizing available horizontal control and GPS survey equipment, conduct a field ground survey to measure and obtain certain planimetric features within the entire right-of-way. Prepare a full rightof-way topographic survey which will include the following content requirements identified below: i. Vertical elements (trees, hydrants, utility poles, light poles, etc.) should be shot with survey equipment on the street side of the item for uniformity and ease of plan design. ii. Topographic and planimetric information such as pavement, existing sidewalks, driveways, ditch lines, side yard swales, fence lines, traffic signals, and existing structures iii. Elevations obtained at regular intervals. iv. Adequate survey shots shall be taken outside of the right-of-way limits to prove flow direction. b. Locate right-of-way iron pipes or monuments. • Prepare final engineering plans and specifications for bidding. Specifications shall incorporate the City’s details relative to the work to be completed. • Attend a kick-off meeting with City staff. • Prepare an engineer’s estimate of probable cost by individual street location. • Verify no adverse impact related to drainage following installation of sidewalk. • Structural design- The potential may exist to design retaining walls to meet current ADA requirements. This may require structural design to ensure the stability of the wall. • Permitting requirements from DuPage County DOT, DuPage County DEC, IDOT and other governmental agencies will require attending meetings with County staff and the City for application of permits. This will apply for roadways in special managed areas or abutting County or State right-of-way. Deliverables • Submit preliminary plans solely showing the intended side of the street and draft path of proposed sidewalk. Reasons should be provided as to why one side of the street was chosen over the other. These preliminary plans will be reviewed by City staff before moving forward with design. • Submit plans for staff review at 75%, 90% and 100% completion. There will be a span of 1 month between 90% and 100% completion due to the City sending out plans to residents for notification and information. • 90% plans should have labels and/or a legend showing removal and replacement of driveways, removal of trees, removal of landscape areas, etc. as to clearly convey information to residents for notification. • Submit AutoCAD DWG files, points files in an Excel format, and word documents upon completion of plans and specifications.
