    Michel Raymond points:

    • Octogon is not activated to be declared by RP, but machining operations could be.
    • Current slots in the TX1 monoblock are occupied by ATLAS, no additional space. If cabes are left outside the slots, there's a danger to damage them as JFC3 is put in place in a "blind" way.
    • Foreseen guiding for insertion of elements in the VAX modules looks ok, but take into account that  the slope of the cavern is 0.7 degrees, the support structure is not horizontal. Keep in mind when designing the lifting frame and  cabling disconnection. Currently there's a direct line of sight for the crane operators but cabling could increase difficulty of operation.
    • JTT opening-  How long does it take to remove the new shielding?Check if JFC1 could be used as a platform to roll over. 

    Christian Boccard points:

    • that tilt is not importantbut BPM should be centered within  0'3-0'4 mm respect to the beam axis.
