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

Conclusion
Beginning to look like an experiment
MTCC finished OK
YE+3 lowered
USC55 looking like an electronics room(s)
Work will now take place on surface and underground
SX5, UXC55 and USC55
Our detector has been split into two detectors
Much different conditions for +Z and –Z ends -Z
much the same as to now; cold, dirty and cramped
all external connections to each disk are temporary +Z
eventually ‘permanent’ connections but not a first
new experience working underground
