6. 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 alloted much time to complete connections and commissioning

7. Work Lists Generic Pre Lowering for +Z Post Lowering
Install in USC55
Install long cables from USC55 to UXC55 plus
Post Lowering
Whatever work can be done
Disk positioned in UXC55
Work on racks
Work on rack to CSC connections
Work on PP to rack routings
Cable chain and ‘services’ to YE+1
Connect from YE+1 hardware to USC55

Cable chain and ‘services’ to YE+2
Same as above for 2
Cable chain and ‘services’ to YE+3
And for 3
Pre Lowering for –Z
Install long cables from USC55 to UXC55 minus
Work within each disk on surface
Seriously consider what temporary services you will need to make full use of this time & to shorten time after lowering
Peripheral Crate Electronics
Pre Lowering for –Z
Test TS4 (8,9) CSCs
Other work finished!!
Post Lowering
Install bottom racks
Disk positioned in UXC55
Continue work on racks

Run LGB tester on all PCs
Cable chain and ‘services’ to YE+1
Connect FO jumpers to modules
When LV and Water available add to CSC Commissioning
Cable chain and ‘services’ to YE+2
Same as above for 2
Cable chain and ‘services’ to YE+3
And for 3
Prepare final racks
PC I&C in final racks with LGB
Develop Little Green Barrack, LGB
Incorporate ME1/3

9. No Balcony
The balcony is missing on the near (+X) side at the far +Z end
Opening to small shaft access from pit
Will present access problems for work
Armando has assurances from infra group that scaffold will be supplied to insure access

10. Safety Underground Extra safety tips: Have a lamp on your helmet
The safety lights are not very bright
Learn your way around the labyrinth
It is easy to become lost because most tunnels curve
Wander around and learn where each room is relative to others and emergency exits
Take first aid training
Required for one or more member(s) of each group working underground
Practical since professional aid personnel are farther away than for surface work

11. Conclusion Beginning to look like an experiment
MTCC finished OK
YE+3, 2 and 1 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
Very different conditions for +Z and –Z ends
-Z Above ground
much the same as to now; cold, dirty and cramped
all external connections to each disk are temporary
+Z Below ground
eventually ‘permanent’ connections but not a first
new experience working underground
