HAWC Budget

• Total Project 9.1M
• Hardware/Construction Cost 7.4M
• This dominated by the tank subsystem 4.6M
• The remaining 2.8M is half site infrastructure
• The Mexican contribution will 1.5M mostly
  covering the site infrastructure costs
• In addition, this budget includes US project
  Management and technical support (1.7M)

Contingency (DoE rules from D0 rebaseline)
0 on items that have been completed, about
10-15 on items that have been ordered, but not
delivered (this accommodates change orders,
delivery costs, etc.), about 15-45 on items
that can be readily estimated based on quotes for
a detailed design, about 45-65 on items for
which a detailed conceptual design exists, but
which may vary due to scope changes such as
channel count, and about 65-85 on items for
which there does not yet exist a detailed
conceptual design, but which is an item required
for the Project.

Contingency Calculation

• Tanks -
• 25 (we have a bid)
• Instrumentation
• 15 (we have significant experience and built in
  some contingency)
• Computing
• 10 contingency as most computation is in later
  years where costs typically drop significantly
• Site Infrastructure (excluding water)
• 25 Our estimate is based on a LANL engineering
  design where US labor rate was used so there is
  internal contingency
• 25 On other estimates come from LMT experience
• The road/electrical is being done for 83k less
  than estimated
• Water
• Add cost of local well to total with 25
  contingency
• Use cost of piped water system as a source of
  contingency funds

Contingency (continued)

• How would we handle a 25 tank contingency
  (1.16M)
• Several possibilities (all assuming other
  contingency is full used)
• Get more money
• 15 supplement from NSF in last year
• Ask the Mexicans
• Get other groups to join
• Reduce number of tanks - _at_ 5k/tank we would
  have to cut back to 650 tanks
• This means twice as long to 5?
• Could populate 250 tanks with two tubes for
  better low energy sensitivity
• Or deploy 170 outriggers we already have for
  better high energy sensitivity
• Go to smaller tanks - 3.7m tanks are available
  from many vendors at 4k (before bulk pricing)

MRI Proposal

• MRI development proposal from Maryland
• Proposal is 2M development proposal
• 30 Match required
• 450k funding from Maryland
• 150k Mexican contribution
• HAWC core array of 256 counters
• Mostly complete (installation, electronics, etc)
• No personnel
• Proposal is competing on campus

MRI Proposal

• Significantly better than Milagro
• Probably move some outriggers (100)
• Can be built in 2 years

Project Management

• Collaboration Spokespeople
• During construction they will be Jordan Goodman
  and Alberto Carramiñana, the PIs
• When the project begins operations, two
  spokespeople will be elected by the collaboration
  to staggered two-year terms.
• Institutional Representatives Board
• a representative from each institution
• This board will make decisions such as
  collaboration membership and authorship of
  papers.
• Project Management Board
• Role will be directing construction and operation
  of HAWC.
• The two spokespeople, the US construction manager
  (Brenda Dingus), and the analysis coordinator
  (Magda González).

33
Project Management

• Maryland will manage all NSF construction and
  operations funds (a role we had in Milagro)
• Jordan Goodman will be PI
• Subcontracts from Maryland will fund construction
  activities at other US institutions
• DoE funds will flow through Los Alamos
• Brenda Dingus will be PI
• The Mexican contribution from CONACyT will be
  managed by the lead institutions in Mexico
  (INAOE, UNAM and BUAP)
• Alberto Carramiñana will be PI
• He will coordinate Mexican funding

34
HAWC Operations Costs

• Milagro Ops budget was 800k/yr (560k to UMD)
• 260k went to Los Alamos through Maryland
• Scott and Michael were paid through UCI UCSC
  240k
• Of the remaining 300k a significant amount went
  to computing and data archiving
• Some went to filters and maintenance
• Los Alamos contributed significantly
• Electricity etc
• We anticipate that HAWC will cost the NSF
  approximately the same to operate as there will
  be Mexican technical support and monetary support
  (like LANL did for Milagro)

35
