Conclusion
Conclusion:
Huge amount of work for CV in the PS Complex during LS2
Priority is given to the achievement of the projects. Needs of operation will be treated if possible.
Please anticipate your request for works and operation needs
Services will be interrupted for long period of time (even ventilation).
All projects and works can not be done in parallel => some of them must be postponed to 2020
CV have to recuperate Bldg. 141 to comply with LS2 Booster planning.
