BACKGROUND
Process Control Systems Upgrade, Project No. J-120, will replace the existing Human-Machine-Interface (HMI) system and data historian with an ABB distributed control system (DCS). The HMI system is the graphical user interface for Orange County Sanitation District's (OC San) treatment plants and collections facilities control systems.
The new DCS requires computer workstations, monitors, and ancillary items which were not included in Project No. J-120 under the Master Services Agreement with ABB Inc. and were planned as owner-furnished equipment. The items selected meet ABB's recommended specifications and OC San's standards.
RELEVANT STANDARDS
* 24/7/365 treatment plant reliability
* Participate in local, state, and national cooperative purchasing programs
* Ensure the public's money is wisely spent
* Maintain a culture of improving efficiency to reduce the cost to provide the current service level or standard
* Protect OC San assets
PROBLEM
The new DCS system requires computer workstations and monitors to be functional. The existing workstations used for the existing HMI system do not meet ABB's recommended specifications. Staff will not be able to use the new system if workstations are not purchased.
PROPOSED SOLUTION
Approve a purchase order for computers and monitors utilizing a cooperative agreement.
