Schedule Comments

• Fast schedule to Build/Assemble/Test relies on
  significant reuse of design
• Orders MUST be placed in January with expected
  9-12 month lead times for gratings/grisms/optics
• Procurements before CDR of items with 4-6 month
  lead times (i.e. major machining)
• Installation at WHT requires early facility
  agreement/processing
• Design verification requires early prototype
  and/or field work ( i.e. fiber run/rotator)

ING/WHT Facility Questions

• Facility Modifications and Installations
• What does the ING/WHT require in terms of
  building modification processes, documentation,
  building code review, inspection or other?
• Does the ING/WHT recommend we use local
  contractors or can we make arrangements for staff
  support?
• Site preparation, electrical preparation, general
  labor for construction services
• Prototype of Fiber Routing
• Will access to the WHT be available for
  prototyping?
• When is the best time (least impact to WHT
  operations)?
