Thank you Jim.
I am in the process of compiling our responses to the
City's 10% Design review comments, which I will get out to you this week,
and these will take care of the first two bullets of BCF item
2. The responses cumulatively took us some time and are lengthy, we
thought it was worth the time to hammer out as much of the detail up front as we
could - but our hope and need is for ensuing review periods to
become more consolidated, in terms of comment
exchange.
On BCF item 2 bullet three, I had a discussion with
Mark a few days ago, and the ability to expedite the BCF schedule to 60% is
possible, but I personally don't think by much. Critical items at the BCF that
we'll need City input and decisions on shortly to keep moving include which odor
control system to design around (4 options were evaluated on a life cycle basis,
and are part of our forthcoming response comments) and the dimensions of
the mixer/conveyor system the City is working to procure.
I think there is ample, and very
realistic, opportunity to expedite the BCF design schedule between 60% and
90% - but we'll keep pushing as efficiently as we can.
I think we can agree that the 10% review period gave rise
to many "mini-evaluations" which we are in the midst of: digestion
SRT/thickening, types of screening technologies, types of dewatering
technologies, odor control methods, evaluation of energy efficient blowers,
interim construction UV/membrane equipment installation options, etc. All these
things have merit to explore, as we want to give Arlington exactly what you
want, but it isn't until we work through them and finalize our design criteria
for all unit processes/equipment that we can really start churning on design.
On budget/schedule issues, please call me at your
convenience. Also on my list of things to do shortly is preparation of our next
invoicing to you.
Let us review your updated status on the action items, and
then I'll attempt to pool together one cumulative current list of issues to
be resolved.
Thanks
