Professional Services Proposal: New Brighton, MN – Sanitary Sewer Capacity Improvement Project November 18, 2019 SCOPE OF WORK Task 1: Field Data Collection & Project Documentation $24,470 · Preconstruction/Topographic Surveying A precondition survey of the existing conditions is needed to properly document the upcoming project. The survey will provide information regarding to property lines, easements, surface features, private utility conflicts, and general site layout. The survey will be used throughout the project including final design of the planned improvements. · Internal Pipe Inspection – CCTV Analysis Bolton and Menk will supply a NASSCO certified pipeline inspector to review the internal pipe condition videos for defects and constructability concerns. The City of New Brighton will be required to contract a pipe cleaning contractor (or televise these sewer segments on their own) during the early stages of the project so that we can use this data to select the appropriate replacement method. · Geotechnical Analysis – Soil Borings The City of New Brighton will be required to contract a geo-technical investigation company (such as Braun, A.E.T., NTI, etc…) to provide soil borings along the project corridor. Once completed, Bolton and Menk will provide a geotechnical engineer to review current soil conditions and provide a recommendation for the appropriate trenchless pipeline replacement methods given current soil conditions. · Easement Review and Documentation Bolton and Menk will supply survey staff needed to review existing property corners and easement data to ensure that the new/rehabilitated pipe (and construction activities) remain within City controlled property. At this point it is assumed that no additional easements will be needed to complete this work. As such, this task does not include any time needed to acquire additional temporary or permanent easements. If at a later stage we determine that this is required, the proposal may need to be modified to include additional time to complete these acquisitions. · As-Built Review Bolton and Menk will review existing pipe as-built documents to ensure the newly installed pipe system operates in a manner consistent with the needs of the community and that no property is adversely impacted with the new sanitary sewer pipe installation. · Private Utility Conflict Review Bolton and Menk will request, review, and survey existing private utilities in the project area to determine potential conflicts and will work with these companies to mitigate these concerns or relocate their utilities as needed to allow for the planned sewer capacity improvements.
