Approve a General Services Agreement with NorCal Pipeline Services to perform cure-in-place pipe (CIPP) lining for the Freemen Canal Pipeline Rehabilitation project in an amount not to exceed $95,000.

The Field Services Department is preparing to rehabilitate a section of the Freeman Canal Pipeline at Alta Mesa Drive in Auburn. The 460-foot long section of pipeline has been the source of many slow leaks over the years.  This particular section of pipeline is almost exclusively located in customers’ back yards with very limited access, making it a good candidate for a CIPP solution.

Pipeline rehabilitation using a CIPP solution involves cleaning and clearing a section of pipe between two access points and then pulling in a flexible liner infused with resin epoxy.  After the liner is in place, a bladder is then inserted, pressurized, and run the length of the pipe to form the liner to the inside of the host pipe.  The liner then hardens to form a structural pipe within the host pipe.

In accordance with the Agency's Procurement Policy, Field Services solicited for and received three quotes for rehabbing the pipe with CIPP technology.  NorCal Pipeline Services was the lowest of the three quotes at $74,300. Because the overall condition of the entire pipe will not be known until the work commences, there is a contingency fund in the amount of $20,700 included in the not-to-exceed total to ensure the work is completed without delay.  This contingency is for unforeseen conditions only and is not a guarantee of work.
