The LSST achieved a significant milestone August 4-6, 2015, with the Camera passing a critical independent review that evaluated the project's readiness for seeking approval of Critical Decision (CD)-3, Approve Start of Construction. The review committee found the LSST Camera to meet all requirements and recommended immediate CD-3 approval. Specifically the committee found the project team to be "expert and very capable. The team is well managed and can effectively deliver on the construction phase tasks, manage the procurements, interfaces, and risks. The management structure and resources are in place to successfully deliver the project within the cost and schedule." The LSST camera final design (including all interfaces) was found to be capable of achieving the previously approved science objectives and sufficient to begin construction. Led by Camera Project Manager Nadine Kurita at SLAC National Accelerator Laboratory and Camera Deputy Project Manager Vincent Riot at Lawrence Livermore National Laboratory, the entire Camera team and LSST Project should be congratulated for this outstanding effort and outcome!
