Nano Plant Chemical Line Replacment-Fy21-02

The project consists of the following: A. Base Bid (Chemical Piping Improvements) 1. Furnish and install all labor and materials necessary for dedicated chemical feed piping for the sodium hypochlorite, caustic, and zinc orthophosphate systems as well as relocation of existing feedwater piping and fittings within process trench to locate sulfuric acid injection downstream of the bypass flow control valve. Construct approximately 257 LF of ½” ZN3(PO4)2 piping, 274 LF of ¾” NaOH piping, 258 LF of ¾” NaOCI piping, valves, appurtenances, leak inspection port, penetrations, pipe supports, chemical piping relocation, injection ports, insulation, heat tracing, thermostats, associated electrical conduits, boxes, miscellaneous piping, supports, and accessory items necessary to provide a complete operating system. 2. The Contractor shall hire Lord and Company, Inc. to perform the programming, controls, and integration for the proposed changes. The contact at Lord and Company is Derek Mathews and he may be reached at (803) 802-0060 or at e-mail address of dmathews@lordandcompany.com. This work includes recalibration of scale inhibitor, zinc orthophosphate, sodium hypochlorite, caustic and scale inhibitor injection systems and modifications to the HMI screens, as necessary. Currently, there are sufficient spare Input/Output to accommodate new signals, however, it is the responsibility of the Contractor to investigate the main SCADA panel to ensure the spare I/O is available at the beginning of the project.
