7. Work status Handling resources are available via our contractor
Tooling and studies to be provided in the frame of this project:
what
Where
status
Delay from go-ahead
Project
Container for L2 dump? L2
Waiting RP requirements. Design started but incomplete
3 months from RP spec L4
Trolley for BHZ20 removal and installation
Design finished, waiting from final confirmation on compatibility with magnet from MME/MSC
2 months from ok
Tooling to remove the LTL line from L2 and install in the SY
L2 and PS-SY
Design not started. Insufficient resources actually
4 months from available resources

8. Risks / Mitigation
Delay in provision of tooling: essentially linked to missing design resources.
Possible mitigation is reinforcement of design team but experienced designers that already know CERN are difficult to find
Accidents due to inherent danger of handling activities
Work preparation, zone delimitations, etc. these dangers are not specific to this site. Same compensatory measures
The unitary time to perform the handling tasks is short and resources are available till a reasonable limit, but limitation of coactivities in the same area can pile up delays. Especially in the switchyard.
I can’t see mitigation action. It should be avoided to ‘profit’ of LHC lengthy stop to ‘anticipate’ LS2, especially in the PS

9. Additional information
Strong dependence on RP feedback on shielding design (and production of blocks), containers, transports, final destination of dismounted equipment and so. Since proper dose measurement is often done at last minutes, this induces a peak activity to last minute design and provision.
Manpower (CERN + contractor) is not a concern up to a reasonable limit

10. Summary Readiness by end 2016? – NO. Risks / Mitigation summary?
Number of studies are undergoing now and not possible to finish them before the end of 2016
Unclear when we should do the different actions (do we need all the tooling in January 2017 or 2-3 months later?). A staggered planning would be important for us
Depending on feedback of groups to finalise the tooling design, in particular RP
Some tools require longer time like the crane for the SY (3 months from order, meaning available in Feb. 2017)
Risks / Mitigation summary?
Increase design resources will help but not easy to find
Continuing design during installation will be mandatory
As general conclusion we are confident that we can stay in the shadow of all other groups to perform our tasks properly and in a realistic planning
