9. First the floor !
second trucks already on the road !

11. First assemble the floor on concrete blocks !!

12. First prepare the floor NP04 (1/3)
Week 33 : for details 
Unload the 2 trucks outside EHN1-NE
Prepare the lab in pitB (cabinets, tools, shims, …)
Bring the concrete blocks in pitB + blocks positioning tool
Position and survey the concrete blocks in position
Pre-position the floor modules on the concrete blocks
Fix the concrete floor non conformity (SMB)
Prepare elastomers and G10 isolation sheets
Prepare grounding safety line needed needed during assembly
Prepare hydraulic to be used for bolting
Prepare for vacuum test and dye penetrant test on SS
Test all tools

15. First prepare the floor NP04 (2/3)
Week 34 : for details 
Assemble and bolt the floor on the concrete blocks
Prepare welding procedure
Survey shape and dimensions
Not done!!!
If possible pre-position cryostat floor in its final location
Weld in between modules the SS plates
Dye penetrant tests and vacuum tests
Glue G10 as isolator below the beams
Pre-position elastomers and rubber

16. First prepare the floor NP04 (3/3)
Week 35 : for details 
If not already done position the floor in its final position
Connect safety ground
Survey position
If necessary correct position by shimming
Receive next 3 trucks (29th)
Start the same type of activities for the first wall as described for the floor week 33-34
Week :
Repeat the schedule of the floor for each wall and roof
Weld SS vessel corners
Where necessary machine SS plates holes and weld local flange (on the roof)
Check overall gas tightness
Make a laser scan of the inside to define the final geometry when assembly is finished

17. Membrane cryostats
SS 1.2 mm primary membrane in contact with the liquid (primary containment)
secondary membrane : composite laminated material (secondary containment)
Insulation : reinforced polyurethane foam (5-6 W/m2)
Full engineering study contracted to the firm GTT in Paris (CERN contract)
All the material necessary contracted to Korean licensed firms (CERN contracts)
Material will arrive in ~16 sea containers 40’ between the 15th October and 10th November
Installation contracted to a GTT licensed firm (CERN contract) which will start beginning of November. Both vessels will be operated at the same time. 15 person will be on side
3 persons of GTT will overview and control the process, including the QA
We will do the final He leak checks with the mass spectrometer
We have to provide all transport and cranes operation and garbage disposal
One CERN Neutrino person will be the link between CERN and the firm for all what has to do with CERN services, daily planning and safety

18. LAr pump and valves
Special valves engineered with GTT and a specialized firm
2 valves contracted by CERN
LAr pumps on FNAL responsibity, already ordered
Installation of pumps and valves part of the contracts
Scheduled for January-February 2017

19. Clean rooms

20. Clean rooms

21. NP04 clean room In the final design phase
We have some preliminary offers
These are class 100’000 grey rooms
To be better defined are the rails and cranes inside for the detector QA and installation
We should start a DO in September
Installation in early 2017
NP02 room not yet designed

27. What is urgent from our side
To get all yellow barriers in place
To get a decent temporary light
To have all building doors installed with the access system operational
To have a decent WIFI coverage
To define space in the hall where we can store for a few months (2-3) material
To define parking space and access for workers to the building

28. A provocation!!! We need restrooms inside the hall
No way in winter to have people to go out to baracks in the fields
The RP requirements should be put in discussion. If it is really true then all the beverage, coffee, water dispensers should go out too.
I think there is room for a rational discussion!
