Budget Impact
The FY 2016-2021 Capital Improvements Plan (CIP) includes the 2016 Sewer Lining Project (UT-SN-14-06). Funding for the project is included in the approved Sewage Disposal System capital budget. In order to take advantage of favorable pricing received through this bid, a contingency amount of $130,000.00 is being added to the attached resolution, so that additional sewer lining can potentially be added to the project. This contingency amount represents the difference between the low bid and the Engineer's Estimate, therefore there would be no change to the overall project budget.

This project includes the lining of approximately 17,265 lineal feet of sanitary sewer at 19 locations throughout the City. Lining is a trenchless technology which enables the pipe to be repaired without disturbing the surface above. The project also includes contingencies to repair some segments of pipe where lining is not feasible. The 19 locations are combined into one construction contract for efficiency and cost savings.

The sewers included with this project were identified by City staff as being in critical need of repair. Lining is a process by which new material is placed into the existing pipe, creating a new pipe inside the existing one. The process is not only cost effective, but also eliminates the need for extensive excavation and lengthy traffic control measures, thereby minimizing traffic disruption.

In response to the Invitation to Bid (ITB-4441), four (4) bids were received on Friday, May 6, 2016. The low bid from Corby Energy Services, Inc. of $645,403.50 is approximately $130,220.00 under the Engineer's Estimate.
