Construction Project Status

For the period of performance October 1-31, 2017

(updated December 6th, 2017)

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).

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).
