Hi Rebecca, I have finally gone through my findings as we were laying out the areas and developing installation plans. As a result, I have the following requests; 1. As we found some potential interferences with HVAC and cryolines in Hall D. We request that a contractor layout be done of the North wall before concrete is poured. 2. After reviewing installation plans in the collimator area, it was determined that we would need some type of gantry system for installation and repairs. Attached is a sketch showing the approximate requirements for ceiling supports. This can also be layed out before concrete pour. This requires plates mounted in the ceiling that can handle up to a 20,000 lb load. 3. After reviewing the plans for installing the tagger magnet, it was also determined that some type of gantry system would be required. Attached is a sketch showing the approximate requirements for ceiling supports. This can also be layed out before concrete pour. This requires plates mounted in the ceiling that can handle up to a 20,000 lb load. This probably entails a new design for the ceiling plate. I am not sure where the money is for this. Thanks, Tim
