Downtown South Bend to Notre Dame Trail <br />Scope of Services <br />05/30/23 <br />Page 2 of 6 <br />O:\Proposals\_Indiana\Governmental\City of South Bend\2023\P23-0011 General Proposals\ND to DTSB Trail\ND to DTSB Trail - Scope of Services.docx <br />intervals. A total of 12 benchmarks are anticipated. <br />11. Benchmarks set for the LaSalle Street project that are near to the project limits will be <br />collected to be used to translate datums between projects as necessary. <br />11. Establish property ownership (including property addresses) and apparent property <br />lines through deeds of record and subdivision plats. <br /> <br /> <br />B. Utility Coordination: <br />1. Existing underground utilities will be located as marked by Indiana Underground Plant <br />Protection Service and by available utility maps. <br />2. The following letters will be sent to utility companies: <br />a. Prior to topographic survey, a Notification Letter will be sent to each utility <br />company identified on the 811 ticket to notify them of the project. <br />b. At approximately the 30% plan stage, a letter will be sent showing the locations as <br />identified by field locates with a request to confirm the presence and location as <br />shown. <br />c. At approximately 60% design, an updated sent of plans will be sent with a Conflict <br />Analysis letter asking to confirm and identify potential conflicts. <br />d. After all conflicts have been identified, a Work Plan request will be sent to detail <br />any planned relocations and a schedule of work. <br />3. Utility potholing is anticipated to be necessary to avoid potential conflicts with utility <br />facilities that can be accurately identified and avoided if practical. <br />4. Once the Work Plan has been established and agreed upon, any relocations will be <br />monitored for progress and scheduling and field visits made as appropriate in order to <br />ensure relocations are performed as planned. <br />5. If necessary, the right of way and any critical features will be staked for the utility <br />companies to ensure they are relocated at the correct location. <br /> <br /> <br />C. Geotechnical Investigation: <br />1. Pavement cores will be taken near the outside edge of each side of the pavement <br />and near the center of the pavement in 6 locations for a total of up to 18 cores. The <br />pavement cores will identify the pavement and subbase below the surface at each <br />location. The proposed locations will be sent to the City for review and approval prior <br />to performing the cores. A City permit application will be submitted for the work. <br />2. Abonmarche will estimate the presence of bricks under the existing pavement based <br />on pavement cores, visual evidence at the pavement surface, and information <br />provided by the City. <br />3. The presence of concrete under the existing pavement will be estimated based on <br />City information and visual evidence from the pavement surface. <br />4. Abonmarche will field check the pavements and attempt to determine if rails from an <br />old railroad are buried under pavements. The field check will utilize previous maps and <br />information provided by City staff.
