In 2013, the Council approved the CBD Sanitary Sewer Rehabilitation Project. Since 2013 the Central Business District has experienced 3 sewer main collapses. The 2015 CBD Sanitary Sewer Rehabilitation Project will address deterioration of the approximately 50 -year old sanitary sewer pipes by relining the pipe with little impact to roadways and minimal excavation. The 2015 Sanitary Sewer Manhole Rehabilitation Project will restore 9 manholes that have deteriorated due to age and hydrogen sulfide gases being released by the sewage flowing through the manholes. As slip - lining sewer mains and restoring manholes is different and specialized work, two separate contracts were prepared. ANALYSIS Seven bids were received on September 29, 2015. Two bids were submitted after the published time that they were due and were not considered. One bid was opened for the slip - lining project and four bids were opened for the manhole rehabilitation project. All bids were reviewed and tabulated (see attached sheet). No errors were discovered in any of the bid submittals. Michels Corporation submitted the apparent low bid of $528,464.52 for the 2015 CBD Sewer Rehabilitation Project and Olson Brothers -Pro Vac, LLC submitted the apparent low bid of $105,068.10 for the 2015 Sanitary Sewer Manhole Rehabilitation Project. Both Michels Corporation and Olson Brothers - Pro -Vac, LLC have previously performed work for the City that was found to be satisfactory. The Engineer's Estimate for both phases of the project was $749,270.00 BUDGET AND BID SUMMARY Engineers Estimate Bid Amount Budget Michels Corporation $ 655,329.03 $ 528,464.52 $ 819,000.00 Contingency 20% 105,692.90 634157.42 Olson Brothers -Pro Vac LLC $105,068.10 Contingency 20% 93,941.15 21,013.62 126 081.72 Grand Total 74 2,, 70.18 7 0.239.14 819 000.00 IV1 W: \PW Eng \PROJECTSW- SW Projects \CBD Sewer Rehabilitation (91140203) \Info Memo 2015 CBD Sewer Bid Award 10 -09 -15 rrt edits mpcgl- sb.docx INFORMATIONAL MEMO Page 2 With the awarding of the two separate bid items at $528,464.52 and $105,068.10 respectively, we also have 820% contingency OO each Uf the projects, ThDCODdDggOCy@DOuOLof812O.O81.72Mk1O5'OO8]U8Od$21,O13.02\isUlg allowable expense that the Mayor will b8 able to approve for any change orders to the construction contracts. |fat any time the project OV8rrUDsih8COOUOggOCy80OUOtStad will return N Committee and Council for approval.

Slip lining the pipe will reinforce the strength with little impact to roadways and minimal excavation. If the pipe collapses, the street will have to be excavated and the cost of the repairs will be significant. In the last five years we have had two major pipe failures on Andover Park West. A Public Works Trust Fund loan was successfully obtained in 2012 for construction. Reduced maintenance and repair costs. The limits of the 2013 project is APW to APE from Minkler Blvd to S 180th St and will now include the repair to the sewer under the railroad tracks. 2015 - 2020 Capital Improvement Program 71 21 22 HCENT fR PARKWAY SO0THCENZE AZTECA LEGEND 2014 MAIN TO RELINED WITH CIPP (COMPLETE) 2015 MAIN TO RELINED WITH CIPP - -- -- 2016 MAIN TO RELINED WITH CIPP 2017 MAIN TO RELINED WIT- CIPP 2018 MAIN TO RELINED WITH CIPP SOUTHCENTER PARKWAY LEVITZ N C� SR 18} WEST VAtt- CASCADE AVE SOUrH ANDOVER PARK WEST,.. ;< ANDOVER PARK WEST INDUSTRY DR.
