1. Gas Schedules

2. I am sure everybody in the experiments feels - as we do - the increasing work load already today.

3. What is the Situation ? CMS: (3xMuons) ATLAS: (4xMuons + 2xTRT)
MUON EDR, PRR done. (Paperwork in a good state.)
TRT pending. (EDR + PRR may be this Summer)
Manpower: construction should be done with PJAS. (not found for the moment.)
Component purity critical.
Undefined areas:
RPC purifier
MDT purifier, humidity in gas ?
TRT systems (active gas + gas cooling)
CMS: (3xMuons)
EDR done (no PRR). (Paperwork minimal, but good and easy cooperation with CMS)
Production of Distribution racks (going well)
Installation handled by CMS (piping contract)
Undefined areas:
RPC purifier
Could cause delays!

4. What is the Situation ? Cont.
ALICE:
(3 big recirc.+ 5 single pass systems)
TPC construction going well (finished Summer 2003) (Orders often blocked bc Budget in the red )
PRR done except for TRD and TOF (follow this Summer)
Paperwork minimal; designs not all complete; cost and manpower definition not finalized.
LHCb:
(2 Standard + 2 Special (RICH) systems)
MUON system design okay (could be final by June 2003)
OT (to be revised before Summer 2003)
RICH 1 (should have started, but C4F10 availability uncertain in the future.)
RICH 2 tests on membranes have started.
Design specs, cost estimates need update, no manpower estimates yet.
No clear agreement for construction manpower !

5. Gas Installation Periods

6. Remarks on the Installation Schedule:
Serious congestion from end 2004 until early 2006 for us.
From the plan our work would be essentially finished in Spring 2006 (one year before start-up !).
We would like to get to a more consistent milestone plan across the experiments.
If an activity is late, what happens to the following installations ?
The schedule is so tight that we must reduce other work, i.e. support work and development activities.

7. Manpower The integration of external manpower is a great concern!
More and more groups want to do pipe work with people they send to us.
Guidelines for external: "pipe workers" and "cablers":
Pipe workers should have experience with gas equipment and must be able to weld pipes, and hold or acquire the required welding permits (European Standard EN-287-1);
Cablers should have basic electrical education (electrician, or equivalent). They should be able to connect gas system components with the control equipment from a cabling plan.
They must speak either French or English.
They should stay on long-term mission (> 12 months), and they must be integrable in the serial module construction.
The number of external persons shouldn’t exceed 3 or 4 at any given time.
The integration of external manpower is a great concern!

8. Suggestions to optimize the Schedules:
Let us know:
What are your constrains and priorities?
What are the modules, that might not be needed at the first instance ?
What is the part of the work that can be scheduled in 2006 ?
Clarify urgently the uncertainties on manpower availability and component purity.
Should we define a policy of how to react onto schedule shifts or delays ?
Minimize deviations from established standards for all systems !
Piping connections of Distribution racks should be done within the “detector piping” contract (example CMS).
Mostly ATLAS (for now!)
Mostly TA1
