H:\ORNO\$2023 New Projects\Fee Estimate - Partenwood Forcemain Improvements .docx May 31, 2023 City of Orono Attn: Adam Edwards PO Box 66 Orono, MN 55323 RE: 2023 Forcemain Improvements - Partenwood Road– Design and Bidding Services Dear Adam: As requested, we have prepared a scope of services and design fee estimate for the addition of Partenwood Road Forcemain to the 2023 Tonkawa Forcemain Improvements. It is our understanding that the scope of the project will include the replacement of approximately 1,500 feet of forcemain along Partenwood Road. Proposed Scope of Engineering Services To assist the City with this improvement project, Bolton & Menk proposes the following scope of services: Topographic Survey – We will document existing conditions and location of the watermain as necessary to construct the proposed improvements. Staff Design Meetings – Our team will work with City staff to develop the scope of the project and to get input on design details. The goal of these meetings is to ensure that the project is designed consistent with City standards and that the City’s maintenance practices and operations are considered throughout the design process. Detailed Design and Bidding – Once the final scope of the project is determined, Bolton & Menk will prepare detailed plans and specifications and obtain all necessary permits. This work will include coordination with private property owners as needed. Upon authorization, the project will be advertised for competitive bids. Bolton & Menk will administer the bidding process and will ultimately make a recommendation to the City Council about awarding the project. Trenchless Design – Due to the curvilinear alignment of Partenwood, we propose to utilize a combination of push camera, crawler, and a sonde to determine an accurate location and alignment on the forcemain to better guide the trenchless design. Should it be determined to exceed the tolerances of pipe bursting, we will proceed with an alternative trenchless design. Temporary Conveyance – The addition of Partenwood to the 2023 Project will necessitate a more robust and complex design for temporary conveyance of wastewater to accommodate the construction of the proposed project.
