Monday, 18 December

08:00 → 10:00 Chamber 1 initial occupancy scenario

- dimensions including tolerances, details of the finishing of the walls and floor, doors - what will be inside chamber (utilities), installed by CF (permanent and temporary utilities: lighting, ventilation, fire detection, fire protection, power distribution, grounding network, evacuation system alarm, phone and wifi …? - which of these items still need better requirements? —>action - what access is available from below? How? - Which emergency services/support we can count on during this phase (emergency, lights and electricity, ventilation, lifts, cranes, access, …)

Speaker: Mr Tracy Lundin (Fermilab)

Slides Interface_Meeting_-_Chamber_1,_Initial_Occupancy_Scenario_December_2017.pdf Interface_Meeting_-_Chamber_1,_Initial_Occupancy_Scenario_December_2017.pptx

10:00 → 10:15 Break

10:15 → 12:15 Chamber 1 cranes and lifts: fresh look, rethinking the monorails

- what functions do cryostat, cryo systems, and FD need to accomplish with cranes? - do we need for the duration of the installation of CF infrastructure, cryostat warm, cryostat cold, cryogenics, detector a set of dedicated and movable elevators? Which type? Who will be responsible? - define an action plan for all of the above

Speaker: Jack Fowler (Duke University)

12:15 → 13:00 Lunch

13:00 → 14:30 SURF surface and underground scenario for storage space

during the construction of the first 2 cryostats and cryogenics and detectors (caverns, drifts, surface building, …)

Speaker: Mr Joshua Willhite (Fermilab)

Tuesday, 19 December

08:00 → 10:00 Scenario of the status of the logistics once cryostat #1 warm structure is constructed

- Who comes next? Which space we will have underground. How access is possible (bridges, ..) - First cold cryostat installation requirements in term of space, material lowering, logistics underground, scaffoldings, amount of people - Second warm structure assembly in parallel? Which additional requirements? - Which infrastructure should be installed at this moment in preparation of the detector installation in the first chamber? - Should mezzanine assembly come at this stage? Define responsibilities.

Speaker: Prof. Marzio Nessi (CERN)

Slides 17-12-19-status-postwarm.pptx

10:00 → 10:15 Break

10:15 → 12:15 Logistics and storage

- Cryostat steel lowering and temporary storage (underground) scenario. manipulation tools, shaft tools, draft transport tools. Define responsibilities and requirements —> action - What is underground personnel requirement during cryostat #1 warm structure construction? - Requirements for assembly & storage space in general off SURF site. Define responsibilities - Transport and logistic issues between these storage areas and SURF. Define responsibilities - Transport top of Ross shaft to underground. Define responsibilities
