Agreed as discussed on the special meeting of last Wednesdays to go ahead b. All parties are reviewing the model provided on Friday by SMB with the new wall c. It was agreed that the tolerance layer cannot be taken out d. EL pointed out that also the halfen rails shall be changed e. Timeline (subject to shift due to COVID-19 impact ) i. Presently: go ahead for wall change ii. For end of March/ beginning of April confirmation on the possible change proposal on the PM iii. Revised metallic and secondary structure for end of June 2) UPR57: following found deviation respect to the foreseen construction plan a. 2 pipes to drain water are getting into the sump on a different wall then the foreseen wall. Fortunately CV can change the integration to manage this b. 2 drainage pipe on another wall get in with different position respect to the foreseen one. CV will change the position of the floaters to manage this c. REMARK. Fortunately these changes can be managed without cost impact. But they have been communicated too late. Documentation and procedure to identify discrepancies shall be refined. THIS DEVIATION WILL BE EXCEPTIONALLY DOCUMENTED AS SMR ALSO IT SHOULD BE AN NCR. 3) SMB asked confirmation that the current distribution of the cast-in channels in the PM from the vertical point of view is ok a. Distribution of halfen channels was analysed. It was agreed to check if possible to have both in P1 and P5 one4 nearer to the PM bottom as presently they are 5 meters away . ACTION SMB ONGOING b. SMB request to use PM57 halfen channels distance of 6.4 meter is accepted. To be documented in SMR 4) EL will provide to SMB with the dates when they need the final 3D models for the UPRs to prepare the drawings for LS2 installation. SMB confirmed that the models will be available on time. Dates from EL accepted a. UPR_UA57: Week 9 (Execution works starting on W19) MODEL provided. SMB to check its content. LATEST construction deviation are not in . See point 1 b. UPR_UA17: Week 12 (Execution works starting on W23) remark it is TODAY. SMB to confirm when available c. UPR_UA13: Week 16 (Execution works starting on W27, to be confirmed) d.

Result of the meeting among fire brigade, HSE, EROS and SMB for the ladders accessing the technical galleries. ECR under preparation. SMB to provide indicative cost for beginning next week 6) SF and SHM: EN-ACE asked it is possible to increase the dimensions of the roller of the sectional doors following contract change. The integration was based on space request coming from EN- ACE and there is not much space available. What can be done from the point of view of INT is in the attached presentation (SHM_SF_DRAW). Please provide any comment for next Monday if not we will use that dimensions as max dimensions for the doors . we stay with present allocation of space . M. Arnaud confirmed that a solution to fit in the foreseen space will be found at the right moment 7) The following dates have been agreed for the next reviews. NEW DATES Due to the implication of the coronavirus perturbation on the above planning it is agreed that we will progress according to the information that will be received from the SMB colleagues 8) SSR: Models done by SMB are ready (from the consultants it might still take a while, but the integration works can start). a. SMB will provide models with the Step 2 review of the SE/SD/SU buildings b. Point 1 IN ANY CASE SMB to move the protection barrier around the He tank to increase protected areas – this has been added to the SMR on the Helium tanks, just for traceability. c. All info to be provided to Timo to write ECR, this should now advance d. NEW Necessary to discuss where to place control of the US sump pump as fire brigade need to switch pump of in case of intervention 9) SD building: elements to protect shaft from falling object a. ACTION: SMB complete proposal and when agreed prepare SMR – SMB informed these will be integrated with the feedback from the phase 3 review. 10) EL informed on a change of dimensions of equipment on the roof of the US safety room. EL prepared 2D drawings that were circulated a. P1: still waiting proposal 11) Grounding technical galleries: a. For the technical trenches to check what is really needed. The problem is not linked to the safety of a person standing on the covers SMB to check with Jose Gascon 12) SHM: CV asked to support the ventilation duct to the overhead cranes beam instead of spitting to the wall. Wax weight 100kg/m. The supporting elements will be connected without welding or making holes on the beam a. SMB confirmed that is ok structurally for 80 kg/meter b. CV to update the models 13) Request for modification from SMB to be documented a.
