additional Basic Services (Design) and Additional Services (Start-up, Warranty Phase, SCADA &
Equipment O&M Documentation) for a fee not-to-exceed $39,700.00 for a total restated fee not-to-

designed control system network architecture to improve reliability and reduce complexity of the

PURPOSE OF AMENDMENT NO. 6
The City staff has requested professional services to provide software programming that will test
and verify the RTAC communication to all associated devices and will verify communication points
with the Facility DCS System. The programming service is exclusive to the RTAC (Real Time
Automation Controller— 1 Unit Total) and the associated Managed Ethernet Switches (3 Units Total)
which function as PCR#2 and PCR#3 Power Protection Network Communication devices. This
equipment serves as the interposing communication between the Motor Protection Relays (22 Units
Total) as well as the Feeder Protection Relays (8 Units Total) located in PCR#2 and PCR#3 and the
existing ONSWTP Facility SCADA system. The RTAC unit will be configured to poll for facility
defined data from the PCR#2 and PCR#3 SEL-710 & SEL-751A relays. It should be noted that this
work was originally in the Contractors scope and it was determined during construction that the
Contractor's integrator did not have the capabilities to perform the programming necessary to satisfy
the contract requirements. As a result, the scope of work as specified herein has been taken out of
the Contractors contract at a deducted cost that equals the amount of this amendment.
