BACKGROUND The existing sewer siphon was installed in the late 1960s and provides services to a large number of Pleasanton residences west of 1-680, from Puri Court at the north to Bernal Avenue at the south. The siphon had reached the end of its useful life and required monthly maintenance to keep the siphon in operation and prevent sewer overflows. The line had lost capacity due to corrosion and permanent grease buildup as is typically seen in older sewer siphons. On May 16, 2017, Council awarded the contract to the lowest responsible bidder, Manito Construction, Inc. in the amount of$1,012,900. On September 19, 2017, Council authorized a change order to Manito Construction, Inc. to procure the fusible PVC pipe for the Yolanda Court Outfall Structure Repair project, CIP No. 17434. DISCUSSION The project consisted of installation of 790 linear feet of 12-inch fusible PVD casing utilizing directional drilling. An 8-inch fusible PVC sewer main was pulled through the casing pipeline. The project installed an 8-foot diameter, 15-foot deep manhole structure at each end of the new pipeline. The new siphon is now in operation. The Operations Services Department requested that a failing manhole across from the DSRSD plant on the west side of the Arroyo de la Laguna channel be rehabilitated. The work was added to the project by change order and completed. In addition, the contractor purchased the 36-inch fusible PVC pipe for the emergency Yolanda Court Structure Outfall project repairs to ensure the pipe would be delivered to meet the tight construction schedule before the winter rains. The project is complete, the siphon and manholes are in operation, and staff recommends the acceptance of the project. Consulting support services will be required to complete the project closeout with the Department of Fish and Wildlife and the development of easement documents for Zone 7. Mosaic Associates is working on the project completion report to the Department of Fish and Wildlife. Kier & Wright Civil Engineers & Surveyors, Inc. is developing the easement documents to be approved by the Zone 7 Board. A total of $5,531 is recommended to remain in the project to pay for the forthcoming invoices. Once final invoices are received, Finance will be notified to close out the project and return the remaining funds to the fund balance. Budget Project expenditures total $1,312,952 and include the design, construction contract, change orders, consulting services and remaining consultant support services as outlined in Attachment 1. The final construction contract cost, including $92,822.17 in change orders, is $1,105,722.17. The majority of the change orders were associated with the purchase of the fusible PVC pipe, complications from directional drilling, and manhole rehabilitation. Page 2 of 3
