preparation of the reference design report
Preparation of the Reference Design Report
  • Design Cost Board will provide guidance and structure, define depth requirements for the elements of cost effort, develop, advise, lead, review, and manage the preparation of RDR.
  • Area Systems Groups are led by full-time teams, coordinate Technical & Global System Groups, and are responsible for providing detailed designs, text, and cost estimates
  • Work together with Change Control Board, R&D Board, and Cost Engineering Team
  • Final Publication Deadline: end of 2006

interaction w area system groups
Interaction w Area System Groups
  • DCB soon has to tell them what we need.
  • Gotta make sure they have the

manpower resources to do the job

on the needed schedule.

  • Determine scope, schedules, goals,

and deliverables.

DCB definitely reviews and approves!

will require monthly reports

one line attributes for cost est
one-line attributes for cost est.
  • inclusive – can’t neglect anything important
  • “parametric” – quantities, escalation, overheads, labor rates, cost vs size or performance (e.g. gradient)
  • Barry - how does cost vary with a performance parameter? e.g. # bunches?
  • bottom-up – some elements, but many

will be top-down, scaled, parametric, etc.

  • flexible – easily follow any scope changes !!!

ILC-GDE Fracati, Italy

global issues will be important thanks jonathan
Global issues will be important thanks Jonathan!
  • Can’t leave anything out: follow all items from conception, design, procurement, testing, inventory, material handling, installation, commissioning…
  • Be careful at boundaries, interfaces, and hand-offs between groups & systems
  • Performance requirements & specs will determine engineering effort at cost
  • Make sure you specify what you need, but don’t over-specify (driving up costs)

quality of evolving cost estimate
Quality of evolving cost estimate
  • Use whatever we have at any given time:

e.g. today we have TESLA TDR & USLCTOS

  • Update as new and better info is available

a “living” document

  • Need to carry along status & date of estimate

& “basis of estimate” tag for each element

  • Goal is to get adequate and sufficient cost

estimate for RDR deadline

ILC-GDE Fracati, Italy

we do have some prior examples
We do have some prior examples
  • NLC Copper Book, TESLA TDR, GLC,

and the USLC Options Study

  • We should review the approach

and adopt what is good

while improving what is not

ILC-GDE Fracati, Italy

Tor sent suggested WBS - PHG updated (112 active cost packages at this time)will expand to > 1000 internal elements

ILC-GDE Fracati, Italy

ok what did we leave out what do we do next
OK, what did we leave out, what do we do next?
  • Exploit our collective project management experience, both within and external to ILC
  • Your input and collective wisdom

are vital elements in this process!

Please help us prepare the RDR!

ILC-GDE Fracati, Italy

what information do we need
What information do we need?
  • Scope (text/pix), Cost Estimates, Schedule
  • Schedule – input to cost estimates, e.g.

needing 600 klystrons over 5 years

may be substantially more expensive

than same 600 klystrons over 8 years

  • Two funding models: (differ betw regions)

technically limited (no time constraint)

or flat funding – same # $ per year

ILC-GDE Fracati, Italy

cost estimate elements
Cost Estimate Elements
  • How many parallel estimates do we need (from Asia, Americas, Europe)?

3 or 4 or 5 site studies!

  • How do you handle multiple inputs into

determining “value”?

  • World-market cost for common items,

must do studies for unique elements

ILC-GDE Fracati, Italy

industrial cost estimate studies
Industrial Cost Estimate Studies
  • TESLA – content and cost estimates confidential

Dieter Trines promised copy of tender for studies

I requested reports without costs – did not say yes/no

  • XFEL – will have CryoModule Assembly and

RF Coupler studies back by mid-2006

content will be public, cost est confidential

B. Petersen & T. Garvey will send copies of tender

  • U.S. Studies – cavities, CM, coupler, CFS ?

not before latter half of 2006 at earliest

  • Asian Studies – content and status?

ILC-GDE Fracati, Italy

will industrial studies be useful
Will Industrial Studies be useful?
  • Will they be in time to be useful for RDR?
  • Will we get any lower level cost estimates?

or just total cost of XFEL Main Linac?

  • How can we insure confidentiality of

sensitive cost information?

We surely don’t want to bias XFEL bidding!

ILC-GDE Fracati, Italy

nitty gritty
  • What is in/out of cost estimate?
  • How do we present cost/value?

as the lowest value (world-market)

average value, range of estimate, probabilistic? 90% CL?

  • What about different SITE-dependent ests?
  • Gotta DOCUMENT what we are presenting & provide a translation guide for each region

ILC-GDE Fracati, Italy

wws group led by hitoshi yamamoto and jim brau
WWS Group led by Hitoshi Yamamoto and Jim Brau
  • Preparing major physics sections:
    • The Physics case for the ILC
    • Detectors – incorporating 3 ideas
    • Simulations of machine & detector interaction:
      • Detector performance, resolution, backgrounds

initially using model of beam: phase space,

momentum spread, disruption, etc.

will soon need fully simulated beam

value rather than cost approach
Value (rather than cost) approach
  • Value is worth to the ILC project,

rather than worth to contributing country

  • Approach developed by ITER (R. Aymar)

vetted through Dan Lehman (US DOE)

  • Countries bid to provide some piece of

project and not funds. Internally apply their own overheads, contingency, and labor rates

to determine their cost, without changing value

  • Yes, ITER has common fund (some % of value assessment–acts as management contingency)

ILC-GDE Fracati, Italy

iter used 100 cost packages
ITER used 100 cost packages
  • ITER assigned “value units” to only

~ 100 cost packages

a pretty high level WBS roll-up

many more lower level items

had to have been cost estimated

and rolled-up to form these packages

  • upon which member countries could bid
  • Does that number make sense for ILC-RDR?

ILC-GDE Fracati, Italy

although some people will tell you that they know exactly how we should define value
Although some people will tell you that they know exactly how we should define “value”,
  • I don’t think we can possibly know at this beginning stage.
  • We don’t want to leave anything out, or close avenues, so we should gather all reasonable information from multiple studies, and combine/average/select only when we better understand the trade-offs of how to present cost or value.

program management tools
Program Management Tools
  • for Project Definition: EXCEL, SLAC WBS, MS Project
  • we will eventually need to migrate to a more powerful,

integrated cost & schedule management system

  • Primavera is the choice at SLAC, ANL, JLab,

but not at Fermilab, DESY, KEK, CERN, DESY

maybe not so useful for project definition

costs: licenses, business computing support

“experts” (consultants), users (us)

learning curves for us

using sophisticated tool will show that we are serious players
