The City of Duluth is seeking a consultant to provide engineering services to complete a condition report for the hillside tunnels that convey Coffee Creek, Buckingham Creek, Clarkhouse Creek, Greys Creek and Oregon Creek through Duluth. To facilitate the Citys selection of a consultant, we are requesting that interested parties submit a proposal for this work as outlined in this RFP. The City of Duluth has numerous streams and creeks that run through the city and outfall into Lake Superior or the Duluth Harbor. The creeks and associated tunnels for this project extend from the west at 23rd Ave West - Coffee Creek, to the eastern creek, Oregon Creek at 23rd Ave East. Each of the creeks conveyance system is unique and is a combination of culverts, storm sewer pipes / tunnels and open channel sections that traverse between City of Duluth right-of-way and private property. The project will be broken into 5 phases or segments, with Phase 1 starting with Coffee Creek and subsequent phases: Phase 2 being Buckingham Creek, Phase 3 -Clarkhouse Creek, Phase 4 - Greys Creek and the final Phase 5 being Oregon Creek. The exhibits attached as Appendix B show each creek conveyance system that include sewer segment data (structure size, material and alignment), aerial image and street names. The information provide in the exhibits is the current GIS data; actual sizes and material may differ in the field. Inspection of the storm sewer for each phase and each segment of each phase as shown. The selected Consultant will provide all equipment and staff needed to perform the work meeting OSHA standards. The Consultant is responsible for all safety precautions that include training and equipment. The inspection shall require personal to enter the storm sewer system to conduct the work. For storm sewer sections that are too small for human entry, the consultant shall provide inspection through remote camera inspection systems. Stationing shall be established for each segment to establish a point of reference for the inspection report. Stationing will be physically marked on the sewer ceiling/roof every 25 and at each point where size, construction type and/or material changes occur. Verification / documentation of the storm sewer cross sectional configuration and material type by station. The City will provide all information it has on the current alignment, pipe material and configuration, but the information is aged and has not been confirmed within the City. This shall be included in the final report. Locate all manholes and pipe penetrations (including pass-thru pipes, i.e. gas, watermain, sewer mains, steam) and note stationing and entry location within the sewer, material type, diameter, active or not (if possible) and condition of pipe connections and manholes. Prepare an inspection / condition report discussing condition issues and general repair and/or replacement recommendations referenced to the sewer stationing, and to include photographs of general condition, general issues and significant condition issues. An example condition report is attached for reference and provides the level of detail the City is seeking. A structural integrity determination shall be made for each portion of the sewer that is located below or within a buildings foundation bearing zone. All 5 phases of the work shall be completed by September 1, 2023. Each phase shall be completed as a separate report and submitted by the date shown below. Each phase shall be considered completed with the submittal of a final draft condition report containing the items discussed above. Below are the dates that each phases final draft report is due. The order of phasing can be discussed with the exception of Phase 1, Coffee Creek, this shall be the first phase due. The goal is for the City to start addressing condition issues as each phase is completed. All questions concerning the project shall be submitted by email to: Tom Johnson, Project Engineer City of Duluth - Engineering Division 411 W. 1st Street, Room 240 City Hall Duluth, Minnesota 55802-1191 tajohnson@duluthmn.gov This Request for Proposal does not commit the City of Duluth to award a contract or pay costs incurred in the preparation of the proposal, or to procure a contract for services or supplies.
