Considerations and Assumptions The previous sections of this proposal provided an overview of the design process for the project. Together with the attached fee spreadsheet, a complete overview of the level of service is presented.While preparing the scope and fees, several assumptions were made and discussed with the City. These assumptions are as follows: • Survey information was obtained during a previous phase of design and will be provided to us for use on the project. • Geotechnical exploration and foundation design was completed during a previous phase of design and will be provided to us for use on the project. • Right of Way and property acquisition will be completed by the City. • Community outreach will be performed by the City. • Temporary Traffic Control: o Left and right lane closures (by time of day) will be used as needed for work in the median and on the outside of the roadway. A speed zone will be implemented when workers are present. The MnDOT Lane Closure Manual indicates we can allow a single lane closure from 9 am to 4 pm, and 6 pm to 6 am for Eastbound traffic and from 7 pm to 2 pm for Westbound traffic since the construction will be far enough away from the signal at Ramsey Boulevard. o A regional detour to I-94 via TH 169 and TH 101 will be implemented for actual bridge erection. Westbound and Eastbound closures of TH 10 will be required.The final detour route will be discussed with MnDOT during final design. o A short-term Riverdale Drive detour may be required during bridge erection. o A Traffic Management Plan will be required, although this is expected to be minimal and similar to other work we have completed on TH 10. o No crossovers of mainline TH 10 will be required. Future Work Phases The goal of our work effort is to prepare plans and specifications that are approved and signed by MnDOT.We understand the project will most likely not proceed to the bidding or construction phases at this time.As a result, future work efforts (not included in this proposal)that will be required are anticipated to include: • Potential update to the Project Memorandum, • Potential updates to plans and specifications, • Revisions to MnDOT project numbers based on funding type, • Permitting process through Lower Rum River Watershed Management Organization, • Bidding phase services, and • Construction phase services. The need and extents of the additional work are unknown at this time and will depend upon timing of future funding for the project. Submitted by Bolton&Menk,Inc.
