3. Material budget update (MTP 2019)
Before MTP 2019: kCHF ( kCHF M2P,  kCHF CtC)
MTP:
additional request 3,320 kCHF
Granted : 2,669 kCHF
OFEN incentives: requested 1,600 kCHF
Granted: 796 kCHF (as not yet available, not included in M budget right now)
After MTP 2019: kCHF
Reprofiling just completed and sent to all GL’s involved.

4. Budget situation on 25.06.19 Too much commitments for 2019
Could block future orders
Adjustment in progress

5. Tech&Safety review #1 Explain the problem in details
Current shielding design exceeds admissible ground loads
Discuss et clarify issues
Propose possible solutions
Or at least identify a way to progress towards some solutions

11. Tech&Safety review #1: outcome
Identify critical areas
Optimize load distribution
Relocate loading areas (avoid the technical gallery)
Optimize mixed area shielding (include magnets in simulations)
Consider local reinforcement (technical gallery)
Consider load & destructive tests (assess concrete composition)
Appeal to Geotechnics company
Define acceptance procedure
Assess seismic response
Propose CERN-wide guidelines (create database)
