Opening a Window of Discovery on the Dynamic Universe

Construction Project Status

November 2016

For the period of performance October 1-31, 2016

The Project earned value toward the MREFC effort rose $8.8 million this month to a calculated $130.2 million. The cost variance rose $1.9 million this month to $6.2 million and changed to a cost performance index (CPI) of 1.05. The schedule variance improved by $1.4 million to -$5.1 million, which equates to a slightly improved schedule performance index (SPI) of 0.96. There were 13 change requests implemented this month resulting in a net contingency return of $107,674. At the end of the month, the Project still has allocated only 10% of the total contingency to the baseline through the change control process. The remaining contingency of $74.2 million is 28% of the estimate to complete. 

There are 29 control accounts beyond the plus/minus $100,000 reporting threshold contributing to the cost variance. The highest value of +$1.8 million is from the Summit Facility control account due primarily to the favorable currency exchange rate. There are 14 control accounts with a reportable schedule variance. The primary contributor remains the Summit Facility at -$3.03 million. This control account has improved slightly this month but is essentially unchanged in five (5) months even though the number of parallel activities has increased – a good sign the effort is stable and moving at the appropriate rate of accomplishment. 

Technical progress is being made across the project. In addition to the fabrication, construction and software development efforts showing visible progress, work to detail the Commissioning phase and to develop the updated Operations plan has also progressed this month. Commissioning planning focused on the handoff interactions from the Camera and Telescope and Site subsystems into the Commissioning phase, detailing handoff milestones and system conditions. The Telescope and Site team will have an internal review of their Assembly, Integration and Verification phase in November. This is important predecessor work for Commissioning and will provide vital contributions to preparations for the agency led Commissioning review scheduled for 24-26 January 2017. The Operations Plan has made significant progress this month as the team prepares for the internal review scheduled for 7-9 November 2016.

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).
