Construction Project Status

For the period of performance February 1-28, 2019

(updated April 15th, 2019)

Project earned value (EV) toward the MREFC effort rose $7.3million this month to a calculated $296.5million. The cost variance (CV) changed $2.94million this month to -$5.3million, and the cost performance index (CPI) increasedat0.98. The schedule variance (SV) changedby-$4.61million to -$4.1million, which equates to a schedule performance index (SPI) of 0.99. These improved metrics are attributed to change requests implemented to add budget at completion (BAC)to the summit facility construction Work Packages and Dome construction. There were 14project controlschange requests (LCRs) implemented this month; 10had an impact on cost or schedule, resulting in a net contingency drawof $4,026,547. All of these LCRs were accounted for in our bottom up estimate at completion (EAC). As of the end of the month, the Project has allocated 58% of the total contingency to the baseline through the change control process. The remaining contingency of $34.6million is 25% of ETCI1(ETCI=BAC-BCWP2) and 23% of ETCII (November2018 bottom up).
(ETC = Estimate to completion, BAC = Budget at completion, BCWP = Budgeted cost of work performed).
