LBNE Far Site Internal Conceptual Design,
Cost, Schedule and Risk Review

6-9 December 2011


Assess the status and adequacy of the conceptual design for LBNE Water Cherenkov Detector (WCD), Liquid Argon Detector (LAr), and the associated Conventional Facilities (CF) at the Far Site (Sanford Lab). This review is to identify areas of weakness, and to recommend actions necessary to bring these elements to the level required for a successful DOE CD-1 review, currently planned for spring 2012. In addition, this review will assess the cost and schedule status of each subproject.

This review will cover only these three subprojects of the overall LBNE Project. (The conceptual design, cost, and schedule for Beamline, Near Detector and their associated Conventional Facilities at Fermilab are covered in separate reviews.) For this review, the four subcommittees will each be responsible for the technical aspects of the subprojects of WCD, LAr, and CF, plus cost/schedule. Each technical subcommittee should respond to the charge questions independently.

See a Brief Introduction to LBNE

Note that LBNE is still carrying three far detector options, a 200kt water Cherenkov detector at 4850L, a 33kt liquid argon detector at 800L, and a 33kt liquid argon detector at 4850L. The decision regarding which detector configuration will be used for LBNE will be made shortly after this review.

Charge to the Review Committee

  1. Are the physics requirements clearly stated and documented? Have these requirements been translated into technical performance requirements and specifications? Is the design technically adequate and is it likely to meet the technical requirements?
  2. Can the design as understood today be expected to be constructed, inspected, tested, installed, operated and maintained in a satisfactory way?
  3. Is there adequate supporting documentation to support the conceptual design and the transition to developing the preliminary design?
  4. Have alternate designs been considered, and has there been sufficient engineering analysis performed to allow evaluation of the relative strengths and weaknesses of the alternates relative to the reference design?
  5. Are the risks (on technical, cost, and schedule basis) of the selected base design approach and alternatives understood and are appropriate steps being taken to manage and mitigate these risks?
  6. Have areas been identified where value engineering should be done? If value engineering has been performed is it documented?
  7. Are the project organization and lines of responsibility clearly defined and sufficient to ensure the successful engineering and design of the project? Are the design interfaces between the Far Detector and Conventional Facilities groups understood and well enough defined to ensure a coordinated effort and an integrated design?
  8. Has the project developed a quality resource loaded schedule that includes the entire project’s scope of work and is it achievable?
  9. Are the estimated cost and proposed schedule ranges realistic, consistent with the technical and budgetary objectives, and justified by the supporting documentation? Has all the work been appropriately identified, estimated and scheduled, including the work associated with performing the preliminary design, final design and value engineering activities?
  10. Are recommendations from past reviews being addressed?
  11. Are there any other issues regarding preparation of the conceptual design for CD-1 that should be addressed?
