Ranger completed all the original contract and contract change order work by April 2017 with the exception of the Sports Park booster station procurement. On May 29, 2018, the City released the project retention after completion of a one-year warranty review of the work. DISCUSSION Ranger Pipelines, Inc. completed $16,801,233 of work that consisted of installing the backbone of a recycled water system servicing Hacienda in northern Pleasanton, Ken Mercer Sports Park, and Tennis and Community Park. Approximately 9.7 miles of new recycled water pipelines, two turn outs (metered connections to DSRSD's recycled water system and the City of Livermore's system), 136 customer service laterals, procurement of a booster station, and repurposing of the Tassajara Reservoir and Clean Water Revival Line. Forty-four change orders totaling $2,052,208 were issued, including the balancing change order. Change orders generally were for additional work to extend and improve the recycled water system. The work included the extension of pipeline down Gibraltar Drive, procurement of the Ken Mercer Sports Park booster station, Tassajara Tank valve vault improvements, permanent recycled water system pipe flushing locations, changes to restraint pipe lengths, and various other issues associated with unforeseen conditions. The change order work also included Ranger performing three emergency repairs to the City's potable water system. They were asked to perform the repairs because they were mobilized in the City with the right expertise and equipment to most effectively perform the work. Ranger performed emergency repair work on the potable water system when the water line failed in the planter box areas on the box culverts at Stoneridge Drive at Chabot Canal, West Las Positas at Chabot Canal, and West Las Positas at Tassajara Creek. These failures all occurred due to the soil settlement in the area adjacent to the relatively rigid bridges. The change orders totaled $365,485 and were billed to the Annual Water Line Replacement Project, CIP Nos. 14128/15128. These expenditures are not eligible for loan and grant reimbursement. At the Ken Mercer Sports Park, the pavement restoration limits were extended along the full length of Sports Park Drive and parking stalls to replace failing asphalt. The work included installation of a new asphalt concrete berm to accommodate the overlay. A total of $330,722 was billed to the City Parking Lots-Resurfacing Project, CIP No. 13434. These expenditures are not eligible for loan and grant reimbursement. The recycled water line was extended by Ranger through the intersection of Bernal Avenue and Valley Avenue prior to the resurfacing of the intersection. A total of $58,697 was billed to the Valley Avenue Recycled Water Main Extension Project, CIP No. 16148. This work was outside of the environmental clearance area for the State funded project and not eligible for loan and grant reimbursement. The project included full-lane-width milling and paving to restore the roadway after the pipeline installation. The SWRCB deemed full-width milling non-eligible, and only covered the cost for paving over the trench line. A total of $318,173 non-eligible work for Page 3 of 4
