Agreed date Next steps: Activities scheduled until 15/08 and after delayed EP activities in

Agreed date Next steps: Activities scheduled until 15/08 and after delayed EP activities in Pit_B CERN activities has been reviewed after 15/08, following access requested by EP • Permanent barriers installation (EN/ACE) delayed after CE handover ; • Final light installation (EN/EL) delayed after CE handover ; delayed • EP needs to get access on Pit_B from 15/08 onwards 04/08 See Mo. M held on 02/08 btw SMB/EN/EP, URGENT ACTIONS TO EP 15/08 Only CE contractors on site 05/09 CE activities w/ EN -HE and EP teams Pit_B handover to CERN before the 15/08 if possible! + Flatness works on the slab are still needed to reach EP needs

Conclusions: ACTIVITIES AFTER 15/08: § All CERN activities scheduled after 15/08 inside the worksite

Conclusions: ACTIVITIES AFTER 15/08: § All CERN activities scheduled after 15/08 inside the worksite area need to respect Safety Conditions imposed by a worksite of Category 1 § EP and EN/HE must submit their procedures and the PPSPS to SOCOTEC for approval before works start § EP and EN/HE reference persons must participate at the VIC, scheduled for the 09/08 at 15: 30, with SOCOTEC, MOE and SMB § SMB activities have the PRIORITY during this period. Claims generated by conflicts due of CERN activities must be avoided. The common goal of “Final CE Handover” for 05/09 has to be pursued REMIND: § To access the CE worksite area, particular safety rules need to be respected, therefore for any visit, intervention, work, etc. . , everyone is invited to taking contact w/ SMB reference person (Estelle FONTAINE or Martin MANFREDI).
