CE Status: Activities executed until 03/08 and ongoing 19/07/2016 03/08/2016 (1) INSIDE HALL: Removal of last cladding separation and columns towards EHN1 completed. Rainwater pipes deviation and crane connection are done on Saleve side. Same activities are ongoing and scheduled for next week on Jura side. Removal of concrete wall is ongoing (~15m of 50m are done). Activity is supposed to be completed next week. Finishing works inside pits ongoing. Priority is given to Pit_B whose access has been asked by EP from 15/08  Upcoming Tasks: Slab btw existing and extension ; Metallic platform connecting w/ existing one at Jura side ; Finishing works Pit_A ; Overall finishing works on the slab and painting on metallic structure ; Materials disposal using existing Saleve door ; Skydômes commissioning ; Smoke screens installation

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).

New platform connecting existing one -> ISSUES 1) Implantation of 4 columns are inside “Supervised Area” OPTIONS: Either modify barrier position or we allow local intervention of SMB contractor beyond “declassified zone” ? 2) Two beams HEB200 will be placed btw axis 25 and 25b and connected to the side concrete wall. Conflict with existing services are detected. SOLUTION: Is it possible to temporarily or permanently remove them ?
