(updated July 24th, 2020)
Project earned value (EV) toward the MREFC effort rose $3.9 million this month to a calculated $365.4 million. The cost variance (CV) changed $1.1 million this month to -$6.7 million, and the cost performance index (CPI) held at 0.98. The schedule variance (SV) changed by $0.5 million to -$2.9 million, which equates to a schedule performance index (SPI) of 0.99. There were 4 project controls change requests (LCRs) implemented this month; 2 had an impact on cost or schedule, resulting in a net contingency draw of $93,830. As of the end of the month, the Project has allocated 65% of the total contingency to the baseline through the change control process. The remaining contingency of $28.9 million is 38% of ETCI (ETCI=BAC -BCWP ), 34% of ETCII (monthly bottom up), and 26% of (TPCII -BAC-CV)/(EACII -ACWP ).
(ETC = Estimate to completion, BAC = Budget at completion, BCWP = Budgeted cost of work performed).

Financial support for LSST comes from the National Science Foundation (NSF) through Cooperative Agreement No. 1258333, the Department of Energy (DOE) Office of Science under Contract No. DE-AC02-76SF00515, and private funding raised by the LSST Corporation. The NSF-funded LSST Project Office for construction was established as an operating center under management of the Association of Universities for Research in Astronomy (AURA). The DOE-funded effort to build the LSST camera is managed by the SLAC National Accelerator Laboratory (SLAC).
The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 to promote the progress of science. NSF supports basic research and people to create knowledge that transforms the future.
NSF and DOE will continue to support LSST in its Operations phase. They will also provide support for scientific research with LSST data.
