  1\.    Magnet Braking     With all the weight on the cart and magnet mover going down this slope, what are    G. Gentry    Mayling Wong 
         Systems            the chances of magnet falling off or a load breaking away. How are the braking                                
                            systems for these two machines, what are the possibilities of this systems failing.                           

  2\.    Zero Layer         Need to decide \"early\" (How Soon?) if zero layer installation is to be changed    D. Ayres     I.T.         
         Schedule           from 1 shift/day to 2 shifts/day. If decide to accelerate schedule too late,                                  
         Acceleration       following tasks may not be able to get ready in time. (Man power resources

  3\.    Magnet Steel       Ultimately, the magnet is aligned relative to the beamline. What I think I heard    J. Kerby     Sam          
         Installation       was that the stands are installed, and then the magnets on the stands. Consider the              Childress    
                            tolerances needed on the stand placement, and your ability to move the stands when                            
                            doing the final placement at the magnet off the transporter. (Goes for other                                  
                            components too)                                                                                               

  4\.    Magnet Status      Confirm the individual magnet (& other tech components) are Ok\'d to go into the    J. Kerby     Sam

  5\.    Block Transporting Having two forklift drivers and one truck driver appears to be very inefficient.    P. Martin    I.T.         
                            The forklift drivers are going to be sitting & waiting most of the time. A second                             
                            truck driver would be much more efficient - one could be being loaded at the                                  
                            railhead while the other is being unloaded at MI-65. (Analyze this cost benefit of

  6\.    Scheduling         Nice scheduling layout. How much flexibility is there for tasks that sit later in   M. Wong      Tom Prosapio 
         Question           the schedule can be moved up when there is available time/resources?                                          

  7\.    Access             Is there keyed access to the stairs at MI-65?                                       J. Cassidy   Mike Andrews 

                                                                                                                                          

  8\.    Ventilation        How will the configuration of the ventilation system at MI-65 & target hall affect  J. Cassidy   Elaine       
                            the ventilation system currently in place a the absorber room and MINOS hall?                    McCluskey    

  9\.    Radio              Tom Prosapio said that the 2-way radio system works well for the 2 following        W.           Bob Ducar    
         Communications     conditions: 1) in the access shaft from top to bottom 2) in the tunnel from one end Boettinger                
                            to theother, but not from inside the tunnel to the surface. Is it possible to use a                           
                            repeater (signal booster) in the access shaft so that someone in the tunnel can                               
                            talk to the surface and vice-versa. This communication ability would be great to                              
                            have in an emergency.                                                                                         

  10\.   Air Seal           The air seal in the target hall pit is made of a material by the name of galveneal  W.           Andy         
         Installation -     which galvanized sheet metal. It was mentioned that the air seal is to be welded    Boettinger   Stefanik     
         Galvaneal welding  along the bottom seams. My question is actually two. 1. Is it a good idea to weld                             
                            on a galvanized material seeing as wehn welding may poisionous gases are produced?                            
                            (maybe the bottom seam could have a mechnical lock, like is done in ductwork in                               
                            HVAC work) 2. What would be the expected life of the air seal given that 1) the                               
                            welded areas are no longer galvanized, 2) corrosion ususally starts in the heat                               
                            affected zone, 3) the humidity of the area that the welds will be in, 4) the area                             
                            will probably never be able to be repaired to to the high radiation?                                          

  11\.   Magnet List?       Need a list of magnets, with serial numbers & status, that will be installed in     W. Smart     Sam          
                            NuMI (carrier & pretarget).                                                                      Childress    

  12\.   Installation of    How are transporter rails attached to 1/2 inch steel plate on the target access     W. Smart     Jim Hylen &  
         Transporter Rails  area floor? How many times will the transporter rails be installed & removed?                    Tom Prosapio 

  13\.   MI65 Hardstand     With 304 blocks on hardstand (week 4) are they going to be arranged so first blocks W. Smart     Tom Prosapio 
         blue/green blocks  needed (for installation) are available?

  14\.   Pre-Installation   Develop a plan for certifying magnets before they are delivered into tunnel.        P. Martin    Sam          
         Checkout           Possible checks included: 1. Hi-pot, 2. Flow test, 3. Leack check, 4. Basic                      Childress    
                            electrical (l, r,)                                                                                            

  15\.   Entry Procedure    Realize that discussion of entry procedure may not be in full agreement with the    B. Ducar                  
                            final \"approved\" procedure.                                                                                 

  16\.   Daily Work         The daily work planning meetings should include a short term forecast of \"new\"    B. Ducar                  
         Planning Meetings  work to be started. Knowing of new work a few days in advance can really help to                              
                            smooth out the installation.                                                                                  

  17\.   Target Chase Liner The apparent new choice of a galvanite liner for the target chase brings            B. Ducar                  
                            significant safety concerns given its being welded. In the whole, this could really                           
                            be a big time penalty to near critical path work. Material choice being driven by                             
                            corrosion for a chase. This is now fundamentally dry & will get quite warm during                             
                            operation!                                                                                                    

  18\.   Roof Panning       Concern that copper pipe from new roof panning to be installed by ragnar benson     B. Ducar                  
                            will clog with calcites & rusticles. This is also a concern for existing panning.                             

  19\.   Maintainng         Debris must be kept clear of the ? System. What measures will be taken to assure    E. McCluskey Greg         
         Cleanliness        this condition of cleanliness (nuts, bolts, wire, debris)?                                       Lawrence     

  20\.   Accomodating RBI   How will this be handled?                                                                        Tom Prosapio

  21\.   Ventilation System Should be operatble 2 weeks prior to beneficial occupancy (so we can ? The tunnel)               Tom Prosapio 

  22\.   Magnet Stands      How heavy are they, and what is the provision for moving them up the slope of the                Mayling Wong 
                            tunnel?                                                                                                       

  23\.   Evacuation of      The power supply and RAW water utility room has only one exit to the bottom of the  D. Tinsley                
         Power Supply Room  shaft. Egress must be made past the elevator cage to get to the emergency exit                                
         in Case of Fire    stair well. It was noted during the review that there is water sprinkler system in                            
         and or Smoke       the area that would help suppress fire. There is still a problem with smoke. In                               
                            case of smoke I would suggest that PPE hoods with air supply be kept in the power                             
                            supply and RAW water utility rooms. This would enable the personnel to evacutate to                           
                            the stairwell.                                                                                                

  24\.   Welded Gaveneal    [The following two paragraphs are taken from International Zinc Association web                               
         Air Block Seal     page: http://www.iza.com/zwo_org/Applications/Continuous_Galv/030609.htm The AWS                              
         Between Block      specification calls for welds to be made on steel that is free of zinc in the area                            
         Layers             to be welded. Thus, for galvanized steels, the zinc coating should be removed at                              
                            least 2.5 to 10 cm (1 - 4 inches) from either side of the intended weld zone and on                           
                            both sides of the work piece. Grinding back the zinc coating is the preferred and                             
                            most common method. Burning the zinc away or pushing back the molten zinc from the                            
                            weld area also are effective. However, while a zinc free weld area is preferred, it                           
                            is not an absolute requirement. All welding processes produce fumes and gases to a                            
                            greater or lesser extent. However, galvanized steels will produce added fumes from                            
                            the vaporized zinc coating. Welders must identify the hazards associated with                                 
                            welding coated and uncoated steel and must be trained to maintain work practices

                            If it is not possible to weld on steel with the zinc coating ground back away from                            
                            the weld area, OSHA permissible exposure limits (PELs) for zinc oxide and lead may                            
                            be exceeded. Every precaution, including high-velocity circulating fans with                                  
                            filters, air respirators and fume-extraction systems suggested by AWS, should be                              
                            employed. Concerns: 1. Welding zinc coated steel will produce undesirable fumes. 2.                           
                            Welding zinc coated steel will burn away the zinc and the steel will corrode in the                           
                            weld area. 3. Welding steel sheet will warp the sheet. Recommendations: 1. Hot dip                            
                            galvanized steel has better corrosion protection than electrolytic galvanized or                              
                            galvanneal steel sheets. 2. Cost comparison should be made with stainless steel                               
                            sheet. 3. Slip together connection between the sheets should be made like in the                              
                            HVAC industry.  These connections have a moderately low leak rate. 4. Soft solder                             
                            can be used to make the connection leak tight in high radiation areas. 5.                                     
                            Construction techniques of the copper roof industry should also be looked at.                                 

  25\.                      If the installation of the zero layer will really take a month, we should look at   Jim Hylen                 
                            whether ramping up a second shift after the first week would make sense.                                      

  26\.                      A rigorous procedure is needed to keep the tunnel floor drains from getting         Sam                       
                            clogged. This should include identification of responsibility and method to         Childress                 
                            accomplish and maintain these.                                                                                

  27\.                      At the target region presentation, the plate welding to provide an air seal could   Sam                       
                            potentially have a significant a schedule impact which may not yet be incorporated. Childress                 
                            Careful understanding of this effort is needed                                                                

  28\.                      Identification of all early stage alignment resource efforts are needed. For an     Sam                       
                            initial period of \>/=1 month after target region BO, all alignment people will be  Childress                 
                            committed to accelerator shutdown activities. We should attempt to accomplish all                             
                            initial alignment requirements prior to BO,                                                                   

  29\.   Overall            I was somewhat disappointed in the lack of detail presented. This makes it hard to  Phil Martin               
         presentation       make comments on the nitty-gritty aspects of the installation. In particular, the                             
                            biggest task of the target pile installation was not described in sufficient detail                           
                            to allow me to judge as to whether the time estimates are at all realistic. My gut                            
                            instinct tells me this job will take longer than planned. If there are sufficient                             
                            crews, and if there is adequate fixtures, etc. then it could go as planned. I                                 
                            understand (from some discussion afterwards) that the plan is to lower two blocks                             
                            at a time. To go smoothly, this requires at least two people upstairs and at least                            
                            two downstairs during this process. If there is another separate crew to transport                            
                            these blocks, and if there are several of the baskets or whatever are being used to                           
                            transport the blocks, then it might work. But none of this sort of detail was                                 
                            presented.                                                                                                    

  30\.   Organization       This is one area where I am please to see a lot of progress, and of course it HAD   Phil Martin               
                            to be there by now since this effort is really getting underway in less than two                              
                            months. However, the supervisor/task manager structure still seems a bit thin,                                
                            especially if, as you told me on Thursday, the expectation is that Tom Prosapio                               
                            will only be involved till the end of the year or so. I don't think a floor manager                           
                            needs to be present on the evening shift, but if not, then the lead task manager                              
                            needs to be a very capable one and everyone needs to understand his added role of                             
                            responsibility. Since I believe there is only one task going on second shift, this                            
                            should be OK. I would worry about not having enough task managers to cover two                                
                            shifts, with sick leave, vacations, etc.                                                                      

  31\.   Access Control     The plan of allowing only medically qualified individuals, and of using special     Phil Martin               
                            access passes, with employee or contractor ID cards left in MI-65 appears to me to                            
                            be a good solution. Since there will only be a limited number of access passes,                               
                            this controls the total number of people in the tunnel. The only issue I see is                               
                            enforcement. People need to understand that they have to treat this as seriously as                           
                            controlled accesses into accelerator enclosures.                                                              

  32\.   13-Month           If we are starting installation in Oct '03 and ending in Aug '04, what happened to  Bruce Baller              
         Installation       allow the schedule to be shortened by 3 months? Do we have all the tasks?                                     
         period             (checkout, hot horn handling, etc.)?
