Construction Project Status

For the period of performance June 1-30, 2018

(updated August 17th, 2018)

Project earned value (EV) toward the MREFC effort rose $8.3 million this month to a calculated $248.2
million. The cost variance (CV) changed $0.1 million this month to -$4.4 million, and the cost performance
index (CPI) held at 0.98. The schedule variance (SV) improved by $1.4 million to -$5.1 million, which
equates to a schedule performance index (SPI) of 0.98. There were 17 project change requests (LCRs)
implemented this month; 10 had an impact on cost or schedule, resulting in a net contingency draw of
$629,536. As of the end of the month, the Project has allocated 53% of the total contingency to the
baseline through the change control process. The remaining contingency of $38.6 million is 21% of ETCI1. (ETCI=BAC2-BCWP3) and 20% of ETCII (April 2018 bottom up).
 
(ETC = Estimate to completion, BAC = Budget at completion, BCWP = Budgeted cost of work performed).
