1 PUBLIC WORKS DEPARTMENT David A. Jones, P.E., Director January 25, 2017 Franklin Pasture Sanitary Sewer Cure-In-Place Pipe Lining Bid Bid Date: 2/7/17 ADDENDUM NO 1 SPECIFICATION REVISIONS: QUESTIONS AND ANSWERS: 1. Are inspection videos available? Inspection videos are available and can be sent upon request. 2. Can the City provide rim/invert elevations for the manholes within the scope or is there a profile available? The only rim/invert elevations the City has are from sewer as-built plans (dated June 1973) for the downstream section of the sewer. A profile from the City s Stormwater Management Model (SWMM), which was created for analysis of the city sewer interceptors, is attached to this addendum. The profile is corrected between MH 4170 and MH 4173 based on the 1973 as-built information. The rim elevations shown in the rest of the profile are based on an aerial survey and invert elevations are assumed. Manhole reports for MH s 4168, 4169, and 4170 are also attached to this addendum and will provide additional information on existing invert depths. 3. Can the City provide the depth of ground water or an assumed depth for design purposes? - The City does not have any surveyed groundwater depth information but the sewer line is located adjacent to a stream so the groundwater is near the existing surface. 4. Can the city provide any flow data for this line? The City does not have any measured flow data. Included with this addendum is SWMM modeling output for Pipe ID The flow seen in the videos will provide the best estimate of base flow rates. 103 Adams Ave, Lewiston, ME Tel.
