19-April-05 Schedule Milestones There are several ‘external events’ that drive our schedule Pre Lowering Now through movement to shaft Permanent work only within a disk, no disk to disk work Post Lowering (Dec-Feb) Arrival in UXC55 and movement to +Z end of pit Same as above but now have a moving target Disk positioned in UXC55 (Jan-Mar) In position at +Z end but no connections done May have special access problems Cable chain and ‘services’ to YE+1 (April) Cable chain and ‘services’ to YE+2 Cable chain and ‘services’ to YE+3 Ditto for –Z Most time here is pre-lowering Everyone’s schedule will be impacted by these Milestones Services ONLY through CABLE CHAINS include Power to turbines Power to LVPS Cooling water to racks and chambers Fiber Optic installation Dates with Milestones are gross guesses really & mine alone Milestones are for USC55 as well HV cannot be applied until cable chains and services connected to a disk LV cannot be applied … Fiber optic links cannot be installed … The pre lowering of –Z can be split into significant periods Now through finish DT installation No face work But scaffold on YE-1 DT finished through YB0 lowering May open somewhat for face work Scaffold? YB0 lowering through –Z Endcap lowering Wide open spaces SX5 is ours But once minus endcap starts its lowering it will probably be on critical path and not allowed much time to complete connections and commissioning 11-Nov-19 PC I&C
