Report
Summary
The Large Diameter Sanitary System includes approximately 220 miles of pipe with diameter sizes greater than 15 inches and over 1,900 sanitary sewer manholes. The 2019 Large Diameter Sanitary Sewer Condition Assessment Draft Report recommended rehabilitation of 55 pipe segments with a Grade 5 Structural Rating. Grade 5 pipe segments contain severe defects that are the highest priority to rehabilitate. The purpose of this project is to rehabilitate Grade 5 sanitary sewer pipe segments, approximately 17,000 feet, as identified by the assessment report.
The Engineering consultants' services include, but are not limited to: evaluating existing documentation including assessment reports, CCTV video, as-builts, and other investigative data and/or reports that may be available on pipe and manhole condition for the recommended rehabilitation; investigation and recommendation for appropriate repair and rehabilitation methods; and design of the rehabilitation or repair to correct all sewer and manhole defects in identified project locations. The Engineering consultants will assist the City in obtaining all necessary permits, easements and approvals for the work. Project documents will be prepared and submitted for review and approval at 60, 90 and 100 percents including cost estimates, technical specifications, and construction drawings and details. The Engineering consultants will also assist the City during the bidding process.
