The first thing we need to do is compleat the Super Conductor work and the power supply shipment for 12 GeV. This needs to take place tommorrow and Fri due to the fact of the Region 2 stringing fixture is due on Fri and needs to be put in the warehousr. Volker and Dave will need to set what I need to put on the schedule. If these items are added to the schedule we need more time and the run will need to be delayed. We have no slip in the schedule and no manpower. Gary is forklift and crane trained. and your guys know were the items are in storage. DOUG
