QRL Problems
• Conflicts between main contractor and installation subcontractor
have caused many delays and finally CERN was informed of a
change of subcontractor in January. Overall delay is now 8 months.
• The contractor has produced a new planning to recover the delays
but this compresses the time for installation and testing.
• A new installation planning is being optimised to recover the
delays. This is based on installation of 3 octants simultaneously.

Planning
• The contract for tunnel installation has not yet been signed. We
will need approval from FC to increase the volume of this contract
by about 30% (3 MCHF). Since we must sign before June, we need
approval of FC chair, with a justification in June 2004 FC.
• We are now re-planning the commissioning on this very
compressed timescale and which requires experienced CERN staff.
We are evaluating the additional resources we need and the means
to procure them.
• We remain fully committed to providing the detectors with a first
run in 2007.
