ROADWAY PLANS: Title Sheet(s), typical sections, plan-profile sheets, traffic control sheets, special design sheets where needed, phase construction sheets as required (plan & elevation). The CONSULTANT will investigate all local roads within the project limits to determine if realignments are necessary. Factors which may dictate realignments include, but are not limited to, angle of intersection, sight distance, crossover locations, and offset intersections. Survey for realignments will be performed prior to printing Preliminary RIGHT-OF-WAY plans to ensure approval by the COMMISSION (a site visit by the CONSULTANT may be needed prior to survey). If CONSULTANT is not performing the survey, any proposed realignment will be sent to the COMMISSION to ensure accurate alignment information. One (1) set of conceptual plans and cross sections, including all tiff files, shall be submitted to the COMMISSION for review and approval. Allow approximately three (3) weeks for review by the COMMISSION. Part 3 - PRELIMINARY RIGHT-OF-WAY PLANS The CONSULTANT shall prepare and submit preliminary right-of-way plans in accordance with the COMMISSION’S format based on the approved conceptual plan. The preliminary right-of- way plans shall contain the title sheet, typical sections, and plan and profile sheets showing all geometrics, profile grades, construction limits, and preliminary right-of-way limits. The preliminary right-of-way limits should be set to provide approximately twice the normal right-of- way border width, which should represent what is expected to be the worst-case right-of-way for the project. Part 4 - FIELD INSPECTION PLANS The CONSULTANT shall prepare and submit field inspection plans in accordance with the COMMISSION’S format based on the approved conceptual plan. The field inspection plans shall contain, as a minimum: A. ROADWAY PLANS: Title sheet, typical sections, preliminary listing of pay items, plan and profile sheets showing all geometrics, profile grades, construction limits, cross-sections, right-of-way limits, size and location of all drainage structures, as well as any traffic control that will be required during construction. Cross drain structures will be plotted on the cross sections. The right-of-way limits will be based on the normal border width, and will represent the actual proposed right-of-way for the project. After the field review is conducted, the CONSULTANT shall provide the COMMISSION with written updated right-of-way and construction cost estimates. These estimates shall be based on historical cost data from similar MDOT projects. When field inspection plans are submitted, all hydraulic calculations (for drainage areas under 1000 acres) shall be included. 7 B. ROADWAY AND BRIDGE: Any other incidental drawings needed to show pertinent topographical features or special treatments shall be included with these field inspection plans. Any remedial measures required by the COMMISSION’S S.O.P. TMD-20-14-00- 000, Standard Procedures for Construction of Roadways Through High Volume Change Soils, must be identified and incorporated into the design of right-of-way plans. The CONSULTANT shall submit one (1) set of plans for review by the COMMISSION prior to requesting the field inspection. The COMMISSION shall mark on these copies of the plans all revisions or changes required and return same to the CONSULTANT. Allow approximately three (3) weeks for review by the COMMISSION. After completing any revisions, the CONSULTANT shall submit to the COMMISSION one (1) set of field inspection plans for a field inspection with representatives of the COMMISSION and the CONSULTANT at a date mutually agreed upon by both parties. Allow approximately three (3) weeks from the submittal date of the reproducibles for scheduling and completing the field inspection. Part 5 - FINAL RIGHT-OF-WAY PLANS Subsequent to the field inspection, the CONSULTANT shall make all necessary changes which arise during the inspection. After completion of all revisions and changes requested by the COMMISSION, the CONSULTANT shall furnish tiff files of the of draft final right-of-way plans and cross-sections for review by the COMMISSION. The COMMISSION shall note all revisions or changes required and return same to the CONSULTANT. Allow approximately four (4) weeks for COMMISSION review. Upon completion of any and all changes, the CONSULTANT shall submit plan sheets of the project which show the right-of-way and all public and private utility locations and ownerships which will be affected by the construction. The CONSULTANT shall submit one (1) set of cross sections for the project. All related electronic files for these right-of-way plans shall be submitted along with the plans on CD/DVD with a project description (including Project Number, Route, County) listed on the exterior of the disk along with the words “Final RIGHT-OF-WAY.” In lieu of CD/DVD, the CONSULTANT may transmit the files by FTP or e-mail. The electronic CADD files may be in a compressed (zipped) format. The CONSULTANT shall, if requested by the COMMISSION, attend any meetings concerning the project. Any changes or revisions required as a result of the above reviews shall be considered as part of the covered work. NOTE: Preliminary Right-of-Way Plans, Field Inspection Plans, Final Right-of-Way Plans and Revised Right-of-Way Plans shall be submitted in the following two formats: a) Black & White TIFF images (22”x36”, 300DPI) on CD/DVD or other approved media as described in Roadway Design Division’s CADD Manual. b) Printed ½ Scale Plan Sheets. 4.
