The Project Earned Value toward the MREFC effort rose $6.24 million this month to a calculated $195.5 million. The cost variance decreased $0.13 million this month to -$4.0 million, and the cost performance index (CPI) held at 0.98. The schedule variance (SV) dropped by $1.54 million to -$5.7 million, which equates to a schedule performance index (SPI) of 0.97. There were 20 project plan change requests implemented this month; 17 had an impact on cost or schedule, resulting in a net contingency draw of - $4,748,822. The majority of this draw comes from the NSF-approved Base Facility change request (LCR- 1016) for $4.0 million. As of the end of the month, the Project has allocated 25% of the total contingency to the baseline through the change control process. The remaining contingency of $61.4 million is 29% of ETCI (ETCI=BAC-BCWP) and 26% of ETCII (2017 bottom up).
