Site work and new construction of a mixed-use development in Auburn, California. Completed plans call for the construction of a pre-engineered storage facility; and for site work for a water / sewer project.

**As of June 9,2021 This project has been awarded. Start date and completion date has not yet been established.** The project consists of constructing a new pre-fabricated metal building and an engineered loading dock for the wastewater treatment plant sludge dewatering process. Including a mechanical equipment package consisting of a screw press, conveyors, polymer feeders, sludge flowmeter and motorized throttling valve. Other upgrades include new plant water pumps, outlet modifications on the oxidation ditch, a gravity sewer bypass pipeline with a metering manhole, solar ready carports, installation of owner provided EV charging stations, and other miscellaneous site-work The bid must be accompanied by a bid guarantee in the amount of 10% of the total bid by 3:00 p.m. ON THE DATE ADVERTISED FOR THE OPENING OF BIDS. More specifically, pursuant to Public Contract Code 20170 and 20171, all bids for the project shall be presented, under sealed cover and shall be accompanied by one of the following forms of bidder's security in the amount of ten percent (10%) of the bid: (a) cash; (b) a cashier's check made payable to the City of Auburn; (c) a certified check made payable to the City of Auburn; or (d) a bidder's bond executed by an admitted surety insurer made payable to the City of Auburn.

The City of Auburn (City) is proposing to upgrade their Wastewater Treatment Plant (WWTP) sludge mechanical dewatering process to provide additional redundancy to an essential component of the treatment plant process. The proposed 2020 Sludge Dewatering Upgrades project provides an additional screw press and other ancillary dewatering equipment, new buildings and new truck solids loading system. The new system is more efficient, consumes less power than existing equipment and provides needed redundancy to the treatment plant. The dewatered sludge or "cake" is hauled to the Western Regional Sanitary Landfill in Lincoln for disposal. Miscellaneous ancillary plant improvements are also included with the project. Upgrades to plant water pumps are planned to provide additional water supply capacity as a result of the screw press and polymer system water demands. Secondly, a new outlet box level transmitter and motor operated outlet control valve will be installed at the Oxidation Ditch outlet to minimize air entrainment in the water during period of high flows. The project will also construct a new sewer to bypass the aging Pond 1B pump station and measure diverted flow using a Parshall flume. And finally, the project includes solar ready parking shade structures and installation of Owner provided electric vehicle chargers, with provisions to augment the existing solar voltaic systems and to add additional chargers in the future.
