CABLE TRAY ON NORTH GABLE: PENDING The possible options of intervention (SMB <-> EL): EL to temporary remove the tray and protect the cables (before mid-July) before the dismantling process start --> Our contractor remove the entire surface of the wall --> You come back to reposition your cables (after CE handover). EL to permanently remove the tray by fixing the hall cable lighting in the steel beam (like the other axis?) and deviate/cut, after your internal evaluation, the other cables (before mid-July) --> Our contractor remove the entire surface of the wall; Our contractor retains inconvenient or unfeasible to operate even without the tray and we finally conclude to dismantle only the portion below the tray and keep the rest there --> No impact for EL. We will deal with the cables protection during the dismantling process.

GRATING STEPS: DONE
