c.The project schedule must include (but is not limited to) the following information:

Submit final deliverables, preliminary plan/special provisions/estimate review, final plan/special provisions/estimate review (submit to Mn/DOT).

d.The initial schedule must be developed as soon as possible and must be finalized during the design process, based on Mn/DOT’s project timeline (schedules must be submitted to the Mn/DOT Project Manager.)

  1. Project Meetings/Coordination:
  2. Meet with District 3 staff a minimum of 4 times face-to-face at initial project start up and 3 additional times to be determined by both parties. These meetings will be to determine details of project and establish appropriate contact personnel.
  3. Conduct other Mn/DOT contact by telecommunications as appropriate to facilitate plan development.
  4. Set up meetings as needed to coordinate design details/standards with various affected agencies, consultant(s) and other Mn/DOT staff, such as the state signal and sign engineer.
  5. Send meeting minutes, letters, e-mails, notes, etc. to affected parties summarizing project decisions.
  6. Field reviews to gather project information.
  7. Meet with the power company to verify source of power and document the outcome.
  8. Utilize the Mn/DOT Traffic Web Site for appropriate reference material (checklists, sample plan, CADD detail sheets, etc.)
  1. Engineers Estimate:
  2. Work on an estimate with the Mn/DOT Project Manager and final design engineer.
  3. Include in the estimate: A total quantity & cost for each pay item detailing funding splits (state aid funds, local, state, federal etc.), a separate total quantity & cost for non-contract items (state/county/city furnished materials & labor) with funding splits, and a separate tabulation containing a detailed listing of all signal, fiber, signing, lighting and striping quantity proposed.
  1. Signal/Fiber/Lighting Plans:
  2. Prepare plan sheets for a new permanent signal system as shown on the attached layout for the diverging diamond interchange.
  3. Include removal of the existing signal system on the plan sheets.
  4. Design temporary signal systems for construction staging both on the trunk highway and detour.
  5. Signal and lighting plans will be in the proper plan format, coordinate correct, and will contain all necessary design information including (but not limited to) the following: Statement of Estimated, Quantity Tabulation (if applicable), Signature Block, Abbreviations, Symbols, Details (standard & special), Intersection Layout(s) and Wiring Diagram(s), Mast Arm Signing, Interconnect, and “For Information Only” Signal Plans. Incorporate all special needs (R/W limitations, existing sidewalk replacements for conduit and hand hole work, pedestrian ramps, directional boring needs, bridge design needs, special lighting and signal footing needs for retaining wall/ ramp/ bridge / rock or poor soils, etc.) into the design (as applicable) .
  6. Prepare a photometric analysis (lighting level computations) of the interchange and have it reviewed by Mn/DOT.
  1. Special Foundations Work
  2. Design special footings for signal and lighting bases that can be installed into bridges, ramps, retaining walls.
  3. Ensure that a foundations engineer is available to answer questions and prepare a design for Mn/DOT review of special lighting base designs and or special signal base designs. Some light bases may end up in the retaining walls.
  1. Signal Issues
  2. Incorporate two permanent signal systems into the new interchange thatconform to the geometric layout on hand. The design criteria (phasing) of each system will be delivered to the Contractor at initial meeting.
  3. Work closely with Mn/DOT staff to determine the appropriate layout for the signal design. Twosignal cabinets with EVP, battery backup andfiber interconnect are required.
  4. Design one PTZ camera on a signal and connected to the fiber for inclusion in the plan.

Note: The signal design for the project includes 2 temporary signals, to facilitate construction, to be folded into the workzone plan. Mn/DOTdoes not expect to close the intersection of CR120 during construction.

  1. Fiber Issues
  2. Prepare fiber in conduit plans from CR 120, north toStearns CSAH 1 and south to 12th Street North. The final termini of the fiber is at 12th Street .
  1. Utility Coordination
  2. Coordinate with District 3 for signing,workzone, fiber and signal plans, as the final roadway plans will require utility adjustment and relocation. Utility relocation plans, utility tab boxes of existing facilities will need to be proposed and tab boxed by District 3.
  3. Ensure that District 3 is aware of utilities that interfere with the Contractor’s design.
  4. Inform District 3 of what the appropriate utility relocation solution is to avoid a conflict with the Contractor’s design.
  5. Show utility plans on the traffic control plan sheets.
  1. Permanent Signing and Striping Plans
  2. Prepare Pavement Marking and Signing.
  3. Follow all appropriate ,MnMUTCD, AASHTO and federal requirements
  4. Research best practices of governmental agencies for information to appropriately sign and stripe the diverging diamond interchange.
  5. Show existing signsin the plan to be salvaged and or installed on the local road. All existing signs on TH15 will be removed and replaced.
  6. Design new signs to appropriate Mn/DOT standards for installation on U posts, overhead signal mast armsand/ or monotubes. Final sign plans are subject to review by District 3 and the State Sign Engineer.
  7. New pavementmarkings will be ground in poly perform tape on CR120, and ground in epoxy and ground in poly perform tape on TH15.
  8. Design interim pavement markings for construction staging.
  1. Work Zone Plan
  2. Working with District 3 program delivery staff , review Mn/DOT plan sheets on proposed bridge, temporary bypass, detour, r/w, subcuts, retaining walls, proposed tie in of bypasses, final geometric design, roadway profile and location, hydraulic information, final curb and catch basin data, utility company relocation plans, project management team notes, and pavement selection type to design a work zone staging plan that is consistent with the Mn/DOT design engineer verbally suggested staging plan.District 3 will propose a verbal staging and detour plan. Mn/DOT final design squads will prepare a preliminary bypass design for traffic control staging. Later on in the project, the Mn/DOT’s final design engineer will retool the bypass and incorporate the bypass into Mn/DOT’s own final design plan sheet.
  3. Work along with Mn/DOT designers to develop an appropriate staging plan.
  4. Take the basic District 3 staging plan and design temporary signing, striping, and temporary signals to carry TH15 and CR120 traffic safely thru the work zone. The workzone plan will be implemented in the field by the general contractor during construction.
