Civil studies cost issues for Snowmass

• Introduction
• SLAC Conventional Facilities (CF) group
  consists of three (3) FTE (4 FTE until
  recently).
• We are complementary to Fermi lab CF group.
• All are experienced licensed professionals in
  their respective fields
• ILC/U.S. Conventional Facilities efforts at
  SLAC continue in full collaboration with Fermi
  lab colleagues.
• A weekly video meeting is held every Tuesdays,
  to increase interaction and consistency in the
  overall work efforts.
• Collaborated with colleagues at KEK and
  Europe.
• Visited their sites and participated in many
  international conferences and work shops in order
  to coordinate our efforts.

• Goals/Tasks
• Primary
• Continue general development of concepts, sites,
  costs, and schedules for ILC conventional
  facilities.
• Identify and perform civil engineering option
  studies.
• Perform baseline site characterizations for U.S.
  sample site.
• Prepare clear scope descriptions, technical
  requirements and needs, as well as option studies
  to initiate U.S. CDR.
• Secondary
• Support ILC RD with related facilities
• Support ILC Working Groups
• Support and participate in ESH activities at SLAC

• Accomplishments
• Primary Tasks
• Prepared Conventional Facilities Design
  Summaries and Drawings and option studies for
  Superconducting (SC) and Normal conducting (NC)
  for the U.S. Linear Collider Steering Group
  (LCSG).
• This activity comprised of about 50 full size
  drawings and 100 pages of text and included
  cost-estimate studies.
• Assessed Dekalb-IL and Logan Ridge-CA sites for
  SC and NC machine configurations.
• Performed option studies for one tunnel vs. two
  tunnels
• Performed vibration characterizations of the
  Logan Ridge-CA site for NC machine, as well as
  parametric evaluation for the Dekalb-IL site.

• Plan through Calendar Year 2006
• Three milestones are envisioned for the U.S.
  Civil Design Effort.
• Milestone No. 1 - Snowmass Conference August
  2005
• Investigate prospective sites at or near Fermi
  Lab that have been identified for their
  topographic or geologic advantages.
• Develop a reference site by utilizing available
  data from a real site with ideal attributes for
  comparison.
• Prepare a matrix tool in order to identify and
  assess the salient features of the prospective
  and reference sites.
• Collaborate with colleagues at KEK and DESY for
  inclusion of their site assessment criteria into
  the comparative matrix.
• Identify and assess civil design solution for
  alternative machine configuration and options.
• Present a complete and collaborative sets of data
  for the assessment of ILC sample sites, as well
  as for civil option studies at Snowmass.

• Conventional Facilities Site Considerations
  Draft
• Purpose To develop suitable criteria to assess
  the identified sample regional sites in order to
  chose a sample regional site for preparation of
  CDR.
• Following is a top level list of criteria that
  have been considered

1. Site Impacts on critical Science Parameters
2. Scientific/Institutional Support Base
3. Land Acquisition
4. Environmental Impacts
5. Construction Cost Impacts
6. Operation Cost Impacts
7. Environmental, Safety Health
8. Regional Infrastructure Support
9. Risk Factors

• Civil Option Studies Considered Draft
• To present a detailed assessment of major
  trade-off choices in order to reach decision at
  Snowmass or soon after (in time ) for preparation
  of CDR.
• Following is a partial list trade-off choices
  that have been considered

1. Provision for extension for upgrade to 1 TeV
2. Linac tunnel depth
3. Tunnel vertical profile
4. Linac tunnel and service tunnel arrangement
5. Damping ring style
6. Damping ring construction
7. Crossing angles and dumps
8. Number of IRs (one vs. two)
9. Dual IR issues

• Milestone No. 2 December 2005
• Refine and complete the assessments of all the
  identified Northern Illinois site.
• Down select to one factual well documented sample
  site.
• Compare the sample site with the reference site
  in details.
• Clearly define and explain trade-offs and
  alternatives.
• Prepare an assessment report covering the above.
• This report will be reviewed with DOE for
  determining the U.S. regional sample site.
• The chosen U.S. regional sample site along with
  the other international regional sample sites
  will be used for the CDR.

• Milestone No. 3 December 2006
• Combine with the machine and detector
  configuration and parameters to formulate a
  complete sets of requirement.
• Characterize clearly major options for the
  trade-off studies.
• Develop the U.S. sample site CF of the CDR
  including the detailed evaluation of the
  trade-off studies.
• This CDR is not envisioned to be in accordance
  with the DOE Project Management Order at this
  time.
• DOE Rule of Thumb is 1 of Civil Cost Estimate
  for Conceptual Design Report.
• For a 1B Construction Project that Represents
  a CDR Cost of 10M.
• Hence the Need for Definition of the Deliverable
