Hi Julie/Ross,
Sorry for the delay. Here are the answers (in Bold);
The question has to do
with the calculation of the magnetic
field as discussed in the paragraph of the SOW at the bottom of page
2.
The SOW states that “…University
of Glasgow to
compute the
magnetic fields based upon models provided by the contractor.” If
the design is already 35% completed by UoG and complies with the
requirements
in Section 1 of the Technical Specification document, and UoG did the
design
work (assuming their name in the drawing title block indicates they did
the
design work), what modeling is left to be done by the contractor? It
seems that UoG should already have enough information to calculate the
magnetic
fields. The only thing I can think of is that the contractor has to
revise the model/drawings to suit the 35% review comments, then use
that as the
“final” design for the purposes of re-calculating the magnetic
field.
There has been an analysis completed on the initial design. If there
are any changes made to the geometry during the 100% design, the
analysis would have to be redone.
We also have a
question regarding the length of time UoG
needs to do their work. While you have accepted responsibility for
their
performance, it would greatly benefit us to know what the turnaround
time is
for their work so we know how many weeks we’ll have to complete the FEA
work that follows, to make any drawing revisions and still support your
July
DoE review.
UoG can do the work in 2-3 weeks.
Cheers,
Tim

Tim,
Here are a couple of follow-up questions. Please send your
response to Ross, as I will be out of the office after today for hand
surgery, returning Feb. 4.
Many thanks,
Julie
