Background: In 2023, construction began on the Ramsey Gateway Highway 10 project,which includes grade separation of Highway 10 at the intersections of Sunfish Lake Boulevard and Ramsey Boulevard, frontage road improvements on both sides of Highway 10, and grade separation of the Burlington Northern Santa Fe (BNSF)railway crossings of Ramsey Boulevard and Sunfish Lake Boulevard. Construction of this project is scheduled for completion by the Spring of 2026. Numerous City utilities have been and will continue to be constructed and/or reconstructed as part of this project per the approved construction plans. However, during construction, revisions are sometimes required to account for unforeseen conditions in the field, or to provide for future considerations that were unknown at the time the plans were prepared and approved. Change Order No. 23 addresses such required revisions as identified in this case and in attached Change Order No. 23,which has been signed by representatives of the Minnesota Department of Transportation(MnDOT) and the Contractor. In summary,buried sheet pile was encountered during the excavation for sanitary sewer manhole#20. The buried sheet pile was in conflict with the proposed sanitary sewer alignment and needed to be removed in order to install the proposed sanitary manhole and sewer pipe. The Contractor therefore had to remove the buried sheet pile in order to install the proposed sanitary manhole and sanitary sewer pipe per the approved plans. Time Frame/Observations/Alternatives: Observations: This was an unforeseen condition and the Extra Work was necessary in order to construct the proposed sanitary sewer improvements per the approved plans. Alternatives: Adopt Resolution#24-251 approving Change Order No. 23 for Improvement Project#20-11, Ramsey Gateway Highway 10 Improvements. Funding Source: The Extra Work associated with Change Order No. 23 results in a lump sum project cost increase of$68,137.15. Sanitary sewer funds are proposed to pay for this Extra Work.
