Page 3 of 4 There will be additional routine annual operation and maintenance costs for the upkeep of the newly installed system. Staff will need to open or close four isolation gate valves at Val Vista Park, depending on the weather and irrigation needs. If debris and sediment build up in the newly installed pipeline, flushing operations will be required to clean the pipeline. Consultant Services Pakpour Consulting Group, the project’s design consultant, prepared the plans and specifications, provided construction support services to review shop drawings, responded to requests for information, and provided periodic inspections and design clarifications. Under an existing on-call materials testing agreement with the City, Geocon Consultants provided testing services. These services included required specialty testing of the materials for the backfill and compaction of the trench backfill associated with the pipeline installation. Change Orders During the project's construction, several unforeseen conditions were encountered, requiring four change orders for a total of $25,010, including a balancing change order. The additional work under these change orders is described below: Change Order No. 1 relocated a streetlight conduit to avoid conflict with a manhole installation. The existing streetlight conduit was 24 inches below the top of the curb and ran through the center of the proposed manhole. The manhole location could not be adjusted, as it intercepted an existing storm drain for recycled water. The total cost for this change was $6,711. Change Order No. 2 relocated an existing 4-inch Schedule 40 PVC potable water line to avoid conflict with a manhole installation and modified five force main cleanouts, which are part of pressurized sewer pipes that convey wastewater, on the paved area to allow better access for the ball valve, a flow control device, operation. The total cost for this change was $11,773. Change Order No. 3 provided a lump sum credit to the City in the amount of $1,226 for supplying material testing services during the corrective work to address a sag that occurred during the installed horizontal directional drilling line at the southern field. The City’s on-call contractor that performed the material testing for the project was utilized to perform compaction testing for the restoration of the open trench segments. Change Order No. 4 was a balancing change order. This change order was issued to revise the contract amount based on the adjusted quantities measured in the field to complete the work. The total cost for this change was $7,752. All the work and project close-out documentation has been completed to the satisfaction of the Interim Director of Public Works. Staff recommends that the City Council accept the project as complete. EQUITY AND SUSTAINABILITY Approval of this action advances the Citywide Climate Action Plan 2.0 (CAP) - Natural Systems by avoiding the discharge of recycled water into the creek thereby enhancing the ecosystem’s health.
