System shall include fuel system status display through <br />the plant’s existing SCADA system. System shall include a local HMI displaying status of the <br />fuel system. <br /> <br /> <br /> <br />Purpose of WCD-010: 1. The per design fuel system had a TMC 3000 leak and level <br />monitoring device "controlling all other fuel system controllers" Ref. M104 and M301. The <br />specified TMC 3000 can monitor leaks and levels but does not appear capable of controlling <br />other fuel system controllers. 2. There was no local display for alarms. A local display will <br />allow operators to see what the problem is. 3. The fuel distribution system diagram on M301, <br />shows a manually operated valve on the fuel supply line to the generator from the day tank. <br />An electric powered solenoid valve, controlled by the generator is required. 4. No conduits or <br />wiring are called out for the fuel equipment. 5. The design provided no requirements for status <br />display or control of the system through SCADA. 6. Per Cummins and the fuel equipment <br />supplier, a low-low fuel level float is required in the day tank and monitored by the generator. <br />This was not accounted for in the design. 7. M101 and M102 have conflicting pipe size <br />callouts. <br /> <br />If a claim is made that the above change(s) have affected Contract Price or Contract Times, any <br />claim for a Change Order based thereon will involve one or more of the following methods of <br />determining the effect of the change(s). <br /> <br />Method of determining change Method of determining change <br />In Contract Price: in Contract Times: <br /> <br /> Lump Sum Contractor’s records <br /> <br /> Time and Material Engineer’s records <br /> <br /> Other - Other <br /> <br /> <br />Estimated increase (decrease) in Contract Price: Estimated increase (decrease) in Contract Times: <br />$69,522.06 Substantial Completion 0 days: <br />If the change involves an increase, the Ready for final payment 0 days: <br />estimated amount is not to be exceeded If the change involves an increase, the <br />estimated without further authorization. times are not to be exceeded without further authorization. <br /> <br />
