Main scopes of the work

• construction of a cooling unit at demineralised
  water for the Outer Tracker sub-detector
• 2. installation of
• - supply/return transfer lines and distribution
  manifolds for the OT
• - supports for pipelines on the RB84 side of
  the cavern
• supply and installation of pipelines and
  equipments for primary water networks and
  compressed air line
• control and electricity works for the OT
• tests on hydraulic performances and control
  functionalities
• commissioning, training and validation of both
  the OT and primary systems
• supply of all required technical documents

Pipe works in the UX85 experimental cavern

• Activities related to WORK LOT 1
• fixation of the supports for 16 transfer lines
  (OT included) along the RB84 side and on top of
  the vault TX84
• installation of the OT transfer lines in
  stainless steel (multilayer pipes use to be
  quoted as an option)
• installation of the supply/return OT
  distribution manifolds
• Activities related to WORK LOT 4
• - installation of pipelines for chilled and mixed
  water (RB86), demineralised water (RB84),
  compressed air (both sides) networks, including
  supports and required equipments

Due to INTEGRATION matters the detailed
activities shall be scheduled and performed
during JUNE JULY 2005

Integration in the SCADA local supervision
IT 3307 Paragraph 4.2.2.1 Communication Four
additional cooling systems will also be locally
supervised and operated from the SCADA local
supervision platform. These cooling systems are
controlled by 3 PLCs, which are also built on
Schneider Premium TSX equipment. These PLCs are
not included in the scope of the supply of this
Technical Specification. 1 PLC Inner Tracker
- Tracker Trigger 1 PLC RICH 1 2 1
PLC VELO The Contractor shall integrate in the
SCADA local supervision platform database the
process data from these 3 external PLCs. The
Contractor shall develop, test, install and
validate on-site the local supervision means
corresponding to these external cooling
stations...
Provided commissioning of the cooling systems
whose PLCs shall be integrated end of FEBRUARY
2006
