Telescope Assembly, Integration and Verification (AIV) WBS 04C. 14 J Telescope Assembly, Integration and Verification (AIV) WBS 04C.14 J. Sebag August 2016

Maximize vendor testing and verification Telescope AIV Summary Maximize vendor testing and verification Work with contractors on Factory Acceptance Tests and On-Site Acceptance Tests Include Handling and Safety Hazard from the start to ensure safe and efficient AIV Surrogate masses and Handling procedures verified Rely on Intimate knowledge of Telescope subsystem designs for faster AIV Fully integrated AIV Team Optimize overlap between sequenced activities to avoid schedule conflicts Regular reviews to keep track of construction progress Demonstrate most telescope performances before commissioning Coordination with commissioning and operations

Robust AIV Sequence in Phase with Subsystem Delivery Three Major Phases Organized for efficient and Safe integration and test: Phase 1 (P1): Dome/Mount/Coating Plant (“Heavy Construction”) Phase 2 (P2): Mirror Coating and Mirror Assemblies Integration Phase 3 (P3): Alignment and Testing Phase 1 (P1) ~2years until end of 2018 Phase 2 (P2) ~1year until April 2019 Phase 3 (P3) ~6 months until Sept 2019 START END P1 P3 P2 From LTS-104 AIV Plan

Telescope AIV is Ramping Up AIV sequence has started with preparation of PFlow platform lift tower installation on the summit AIV Equipment is being selected and purchased AIV Integration instrumentation is being designed and contracted AIV team is being consolidated AIV sequence is being updated Example of Assembled Frame Example of Crane being investigated Filter exchanger for commissioning camera PFlow platform lift tower

PFlow Tower Installation Procedure Work with Platform Lift vendor PFlow to define tower installation procedure on site Work with subcontractor to install tower and to verify installation

In the Process of Building Telescope AIV Team Build core AIV team in Chile that will continue during commissioning and operations Include as much as possible current team members into AIV team Some LSST Team members are already present in Chile (Site Manager, Admin, Engineering, Software) Continuing the process of identifying/hiring AIV team Recent Hiring includes Freddy Munoz, Mechanical/Integration engineer (in Chile) James Howard, Mechanical/Integration Instrumentation engineer (in Tucson) Interviews and more job openings this year

Envisioned Roles Needed for Telescope AIV Team Project Roles: Telescope Team Management, Summit Site Manager, Resource Allocation (PMCS-EV), Safety Coordinators (2), Administration, Facility Operations Deputy Project Manager for AIV, System Engineer, Documentation Specialist, Data Analyst Scientific Roles (Telescope, Calibration, Scheduler) Engineering Roles: Mechanical (5), Electrical (4), Software (7), Optical (2), Coating, Network, IT, Computer, Calibration/Site Monitoring Technician Roles: Mechanical (4), Electrical/Electronics (3), Optical, Coating, Network/IT, Calibration, Telescope Assistants (2)
