Summary of NCSX
On-Site Fabrication Meeting of Tuesday, July 25, 2006
1.
Cost and Schedule Trends and Issues
- Cost trends on Type C’s
continue to be favorable overall. Occasional setbacks.
- Seeing expected cost uptick
on initial Type A steps.
- We are 12 working days
behind on C5 critical path.
- We will increase to 2
shifts on Station 1b next week.
- Type A cladding is late and
may impact schedule. Action: Larry follow up with supplier.
- Larry is looking for
alternate EDM sources for Type B cladding and chill
plates.
2. Additional winding
fixture
- Costs
(Larry)
- $50K to install
- Awaiting bids for fixture
parts. Assume $40K as a placeholder for now. Also need clamps.
- For discussion purposes,
assume $100k total, and 10 weeks to procure and
install.
Full
implementation scenario (Buy 3rd fixture and staff 2 shifts
per day.)
- Benefit
(Wayne)
- 3.8 month reduction in
the time to complete the balance of the coils, assuming the fixture were
available from today and MCWF deliveries every 20 days. Assume operations
not constrained by staff availability, parts and supplies, or equipment
reliability.
- Risks
- We would increase staff
in effort to speed up the schedule, so we would start spending at a higher
rate. If predicted time savings did not materialize, the predicted
savings would be less. If the larger operation became less
efficient instead of more efficient, it could end up costing money.
- FY-07 schedule is already
at risk due to only $1M contingency. Possibility of a continuing resolution
adds to the uncertainty. If we add winding staff to speed up winding, other
work would get delayed to FY-08, impacting the critical path. Thus, there is
a risk that any cost and schedule benefit to the winding operation would
come at the expense of the project as a whole, resulting in no net benefit
or worse.
- The accelerated scenario
depends on the entire operation running on a precise schedule. If not,
there is a risk of work coming to a halt due to “gridlock” (can’t move a
coil out of a station because of no place to go.) The fact that coils
go thru Stations 1A and 1B on both the front end and the back end means
there is little forgiveness if things don’t go as planned. The autoclave is
busy almost full time and is at risk of becoming a
bottleneck.
Intermediate
scenario (Buy 3rd fixture, but don’t increase
staff)
- Benefit
- Provides and additional
multi-purpose fixture for risk management flexibility to accommodate
problems such as coil re-work, backup for fixture breakdowns, relieve
gridlock. Could add staff later if everything is going well.
- At current staffing
levels, we estimated it would only need to save 2 weeks on the schedule to
pay for the fixture. Action: Wayne estimate time savings. Assume
new fixture available from Dec. 1
Conclusions
- Full scenario has high
potential payoff, but high risk of not succeeding.
- Risks would be less if more
BA were available in FY-07.
- Intermediate scenario may
mitigate risks. Even partial implementation may be beneficial, so
staging may be an option.
- We will follow through on
getting estimates for fixture and clamps.( Larry)
- We will try to quantify
potential benefits of intermediate scenario (Wayne)
- If current assessment
continues to hold up, go ahead with intermediate scenario as resources permit.
Perhaps late August.
Please bring comments or corrections to my
attention.
