2. Introduction CV problems Various updates Proposals and agreements
Current status of the project
Updated schedule
Things to be decided

3. CV problem 1
An extension of the concrete slab behind SR1 (below the current smoke extractor) is needed by EN-CV for the installation of the pre-treatment device.
Alex is in contact with SMB to do this job.
Unfortunately in the same area there is an underground canal (drain? Sewer?).
SMB is now checking the feasibility  Status?

4. CV problem 2
The ducts are placed just over the opening for lights  NOT a problem: either the ducts or the lights will be displaced
TC noticed a lot of conflicts among ducts and the SMB structure as well as among ducts and lighting units. EN-CV is working to update the 3D model of the ducts to avoid these conflicts  Status?

5. Various updates
EN-EL will need a power cut of 1.5 days for Breaker installation + Switchboard replacement. It has been agreed that this power cut will start Wednesday September 20th at 8:00 until the next day at 12:00
In order to remove existing pipes of C6F14 cooling circuit, Piotr is proposing to do the intervention right after EN-EL and to keep the C6F14 cooling OFF until 12:00  on Friday (22/09)  Feasible?
Due to conflicts between the HVAC ducts and the reinforcement of the mechanical structure foreseen by SMB in order to remove the central pillar, it has been agreed to remove the pillar 12 instead of the pillar 14. This will solve the main conflicts.
This has been agreed by the users (see s from Kendall and Eric on 30/08/2017 and from Danilo on 31/08/2017)
Intervention on pressurized air piping has been completed. A new valve has been installed and Piotr can now proceed with pipe removal

8. New proposal for cable trays and enclosures

9. Antistatic floor proposal from SMB
SMB proposed the following flooring solution:
A first layer (primer) made of: Sikafloor 161
A middle layer (with antistatic properties): Sikafloor 220 W Conductive (RG: 103 ≤ R ≤ 104 Ω)
An upper layer (protective and ESD): Sikafloor 262 AS N (RG≤ 106 Ω)
According to Sylvain, the proposed solution is more than enough for the purposes of the cleanroom. Anyway TC would like to have the approval of the users  Kendall
SMB needs a green light by 11/09/2017 (today!)

10. Proposed reinforcement for cleanroom ceiling
The proposal is to reinforce the current cleanroom ceiling with two rows of scaffolding running below the ceiling along the maximum sag of the panels. SMB (Raul Fernandez Ortega) is checking if the proposed solution is compatible with the fake floor and if it is enough to allow people working on the ceiling. The cost estimation for this solution (made by Gianluca Canale) is 2350 € (mounting/dismounting) €/day

11. Current status of the project
SMB completed the concrete slab for extension and the ones in front of the big door. They will need to add the ramp to grant the vehicles access
Pierre confirmed on 01/09/2017 that the work will be completed by 08/09/2017 …what about the ramp?
The access through the emergency door will be closed until 15/09/2017
A corridor in front of this door to exit the fenced area is needed  Pierre
The access through the big door will be closed until 29/09/2017 (T.B.C.)

12. Current status of the project
There is still a lot of works to do, especially from AFP side, ALFA side and Pixel side. According to the overall schedule, SMB should install the temporary protection wall on week 47 (13-17 Nov). In the same week EN-CV should shut down the ventilation.
TC requires that by the end of October (at the very latest) all the devices, services and equipment installed on or close (less than 1.5 m) to the main wall must be removed.
Petr and Sune are ready to move their equipment (AFT and ALFA respectively), but they need a place. TC shall take the final decision  Ludo

13. Updated Schedule Jun 2017: SMB started civil engineering works
Jul 2017: SMB prepare the foundations
Aug 2017: SMB install the concrete slab and the ramp
Sep 2017: EN-EL and IT-CS should remove the cables running on the wall to be dismounted (in between the wall and the building wall)  in progress
Oct 2017: SMB should install the mechanical steel structure and remove the external wall of the building
Nov 2017: SMB should install the temporary partition wall (1m from existing wall) and remove the internal wall of the current cleanroom. CV should start removing the existing components (stop the ventilation for 6 months)
Dec 2017: target for ending SMB works (end of the month)
Jan 2018: TC should start installing the internal clean room extension
Mar 2018: EN-CV should start working on the HVAC system installation. EN-EL, IT-CS should also start working
Apr 2018: target for ending clean room extension installation and commissioning
May 2018: target for ending ducts and HVAC system. IT-CS and BE-ICS should complete their commissioning
Jun 2018: EN-CV should complete the commissioning
Jul 2018: target for commissioning the SR1 clean room extension

14. Things to be decided
The users required to have a minimum height of the ceiling of 3.7 m
Lowering the current ceiling (4.15 m) by 1m is NOT possible  too low
Lowering the current ceiling less than 1m in the existing portion is not advisable (access problems, working/cabling conditions, etc.)
 The option of lowering the current ceiling has been discarded
Two options are left:
- Option A: keep the ceiling as it is in the existing portion and continue the ceiling into the extension
- Option B: remove the ceiling in the existing portion and supply a brand new ceiling over the extended cleanroom
TC prefers Option B, but it depends on the costs. Decision will be taken after Tender

15. Things to be decided Number and position of Ethernet inputs: 25? (tbc)
Total expected power consumption (Pixel/Strip integration, testing, standard activities): (tbc)
Amount of cables and services needed by the user (total cross section, distribution, feasibility of reusing part of the existing cables, etc.)  tbc
Path for cables and services (below fake floor and along pillars or cable trays etc.)  tbc (in September)

20. Safety coordinator
John Robert Etheridge (164647) is the safety coordinator of P1. He will help TC to ensure that all the works will be done according to the CERN safety rules. For all WPs, a VIC shall be prepared after the design phase and presented by the responsible of each WP to the safety coordinator before starting the works. John is invited to this follow-up meeting so that he can be informed about on-going activities and can control that all foreseen/incoming activities are properly planned from the safety point of view.

21. Various solved / agreed points
Susanne re-checked (04/07/2017) and the foreseen future consumption is around 6 kW. Calculation was updated by Alex.
Pierre presented the SMB VIC to the safety coordinator on 12/07/2017.
During the HVAC stop, EN-CV will supply the temporary AHU Trane TSH060 (ordered from November 2017 to June 2018 to be sure to cover the whole period). The device will be stored outside with the duct(s) inside the new room R-C04-A. The R-C014 (rad lab) will be cooled by opening the lateral door, as agreed before. Additional costs will be charged to TC.

EN-CV needs to open a hole of about 50 cm x 50 cm to install the duct for the temporary AHU in the test room. The proposed location of the hole is shown in the pictures above. It has been approved by Didier on 21/08/2017

25. Temporary AHU in R-C04-A
More details and information about the TSH060 unit can be found here
This temporary AHU will be placed outside SR1 (back side) to supply fresh air (hot and cold) in the test room (R-C04-A). The unit will be in use from November 2017 to June 2018.

26. Electrical matters
Current 160A switchboard will be replaced by a 250A switchboard (maximum possible considering actual electrical consumption, future general needs and current transformer capacity).
The order for the new switchboard has been sent on 07/07/2017. Total cost is ≈35kCHF
According to Thierry calculations (see of 30/06/0217) a maximum of six 380V-32A sockets can be used simultaneously in exceptional cases:
4 devices running on 380V-32A sockets can work at the same time with no constraints
It should be possible to add 2 more temporary
Grounding works are completed

27. Electrical study
Thierry completed the preliminary study for WP3: Regarding lighting, he propose to add 36 of this LED lights:
The lights will be installed below the ceiling (as they are now) and not embedded into the ceiling.
The cost estimation is: ≈10 kCHF (cabling excluded)
In case the ceiling is lowered, new lights will be needed. The additional estimation is done for:
Disconnection and removing existing lights
Buying new lights (33 units)
Connexion and fixing new lights (using existing cables)
≈10 kCHF
Regarding sockets boxes, the job will be done in two steps: 1) disconnecting cables and removing existing boxes; 2) installation of boxes on metal pillars and connection of cables (after the external wall will be dismounted)  1 or 2 hours of power cuts will occur

28. Existing socket boxes
Currently, there are several sockets boxes on the external wall in existing room.
Position 1 :
3 boxes with 400V - 4x16A socket (x2).
2 boxes with 230V – 2x10A (CH) socket (x4). One on UPS network.
1 box with 230V – 2x16A (CE) socket (x2).
Position 2 :
No need to reuse these, but in case they can be added on the pillars (opposite to the requested boxes)

29. Position of power boxes in SR1 cleanroom
ACCEPTED

30. Position of the openings for grounding
4 openings (one at each corner) have been requested (by Thierry on 30/05/2017) on the sandwich panels of the walls in order to install and access the grounding loop. On 24/08/2017 Thierry sent the following picture
ACCEPTED
1100 mm
Tolerance regarding dimensions in red is ± 0.5 m

31. Schedule for ITk Pixel tests in SR1
April-August 2017: test of prototype with one full cooling line ~375 W in SR1 (August 2017)
September 2017: commissioning of system setup in SR1 (power needed, few days of outage can be discussed, CO2 partially needed for commissioning)
October-November 2017: assembly of prototype in SR1 (power and CO2 needed, days of outage can be discussed)
November 2017-November 2018: systematic evaluation of demonstrator in SR1, dedicated test bench for comparison of DAQ, readouts, powering, cooling (power and CO2 needed). Short periods of outage can be discussed: a possible solution is to run power extension cables from the nearest building, if needed(tbc)

32. Schedule for ITk Strips tests in SR1
April-September 2017: Testing of pre and post irradiated modules in SR1 + Testing cold (-35°C) with chiller
September-December 2017: assembly of parts for system test setup for a Strip Stave in SR1
January-November 2018: Commissioning of system tests of a stave (CO2 cooling, interlock, DCS, DAQ, cabling)
As agreed with Susanne and Jens, short periods of outage can be discussed

34. Ceiling Lowering
A rough cost estimate has been asked to ER2i and STIC (ER2i did not do a survey, while STIC came and studied the situation):
ER2i
STIC
Assumptions:
no intervention is foreseen on electricity (drillings and cuttings are included, but not the equipment, lightings…)
No dismantling of the existing ceiling
CERN shall remove first cable trays
Rough cost estimation:
Handling structure: 32 K€
PU ceiling, 80 mm thickness: 48 k€
Cuttings / drillings: 6 k€
Survey, lifting, project management: 10 k€
Assumptions:
Lighting is quoted separately
Ceiling will have a rigid structure that allows one person to work on it
No dismantling of the existing ceiling
CERN shall remove first cable trays
Rough cost estimation:
Handling + structure + sandwich panels + scaffolding: 63 K€
Lighting embedded in the ceiling (60 units LED): 25 k€
96 k€
88 k€
TC will add the ceiling lowering of the existing part (not the radiation lab) as an option in the TS for the internal envelope

35. Proposal for openings to access the ceiling
NOT NEEDED: ACCESS CAN BE DONE FROM OUTSIDE

36. Taken decisions
Services cannot arrive from below the fake floor into the pillars: pillars do not go through the fake floor, but they are loading the concrete floor. Openings are present in the concrete floor, but far away from the pillars.
The only possible solution is to run the cables over the ceiling and enter from there into the enclosures.
Cable trays and enclosures shall not cross the rails in order not to lower the ceiling in the assembly region.

37. Taken decisions The clean room will be ISO 8 according to ISO 14644-1
All cable trays shall be covered
WP3 (EN/EL) will take care of all the cable trays related to main electrical services, while WP4 (TC) will take care of the cable trays for electrical controls. Users shall specify their needs ASAP
ESD precaution will be obtained with mats, people grounding and NO new antistatic floor is foreseen in the radiation lab
The SR1 radiation lab can be used by ITk tasks, but needs to be cleared with 1-2 months notice in case of TC/detector needs during EYETS

38. Taken decisions
13 power boxes will be installed by EN/EL. One power box at each of the 4 pillars between existing room and extension (the central pillar will be removed) and one power box every 3-4 m on the wall (evenly distributed). Each power box shall have at least:
4x 220V - 16A (CH standard)
1x 400V - 32A
Local differential switch for each sockets group (one for 4 sockets 230V-16A  and one for socket 400V-32A)
2 existing sockets boxes will be kept on UPS network (in the pillars area). No additional sockets on UPS network are required
Existing UPS network details: 100kVA lasting approx 10 minutes at 80kW (see from Thierry sent on 28/06/2017)
Lighting will provide the same illumination of the actual clean room (≈400 lux)
Type of lights: LED (to minimize the maintenance)

39. Taken decisions
EN-CV will switch off the air conditioning and ventilation for at least 6 months (schedule should meet SMB’s one)
EN-EL will switch off the electricity for small periods of time (schedule should meet global schedule and users’ schedule)
Overpressure targets:
Overpressure of extended clean room (R-C04-B) is ≥15 Pa
Overpressure of radiation lab (R-C14) is ≥15 Pa
No overpressure in the test zone (R-C04-A), changing room (R-202), other areas
Overpressures of R-C04-B and R-C14 can be manually regulated in order to create slight overpressure of the clean room over the radiation lab if needed

40. Taken decisions
The proposal of extending the changing room R-202 by ≈1m has been accepted. The drawings have been modified
To be removed
≈1 m

41. Taken decisions Eric agreed on 16/05/2017
Two rails are required to drive the coaxial installation of the ITk.
These rails will be:
2 different rails, one flat and the other with a V shape (see drawings from Roberto)
Parallel to the extension long side (centered wrt the opening)
36m long and 2m apart ending 7.5m outside the building
Embedded into the floor
No particular tolerances have been added (default tolerances are considered)
There will be a 3m x 8m concrete slab that will host the outside rails and will create a flat area (currently there is a slope) at the same level of the inner floor
SMB shall update the design of the concrete slab
Eric agreed
on 16/05/2017

42. Taken decisions Eric agreed on 16/05/2017
An additional door has been required on the North-East-short-side wall of the extension, to ease the extraction of the ITk assembly.
SMB will design an opening (2.8m wide and 3.5m high) centered in the N-E short side of the extension .
This opening will be closed with a removable wall (not with an external door). This removable wall can be removed using a crane.
The cleanroom will have a correspondent opening of the same dimensions and will present either an internal double door or another system to guarantee the sealing.
Eric agreed
on 16/05/2017

43. Cooling and Ventilation stop
The stop of CV system for at least 6 month announced by EN-CV and due to the replacement of the AHU and upgrade of the CV system will cause major problems in the ID test area
Didier, Anatoli and Dave agree that during such a long stop of the air conditioning, the test cannot be performed
A solution has been discussed among Didier, Alex and myself. It has been presented to all involved people and it has been agreed (see next slide)

44. Temporary solution for R-C04-A during CV stop
The main points which have been agreed from both parties are listed below:
EN-CV will switch off at first only the portion of the system close to the demolished wall (where they have to work), keeping on the system on the other side of the cleanroom (test area and radiation lab). This will lower at the minimum the amount of time people working in SR1 are affected from the CV stop.
To grant fresh air (especially when the R-C04-A will be divided from R-C04-B), the upper door above the emergency door of R-C04-A can be kept open (see attached file).
Being an internal building (building into a building), the SR1 cleanroom should not have huge problems regarding the temperature. Especially in winter time and considering the power dissipated into the test area, the temperature should not drop drastically. Anyway, just to be sure to have always acceptable working conditions, one or two mobile inverter air conditioner can be provided (the cost estimate is roughly around 3-4 kCHF each) so that also people in the radiation lab can adjust the temperature in their working area.
Alexandre will add these points (even if they are related to a temporary solution) into the “Upgrade of SR1 clean room” document prepared by him and circulated for approval.

45. Anti-static floor
The current cleanroom (R-C04-A and R-C04-B) has an antistatic (ESD) fake floor, while the radiation lab (R-C14) has not. Tests have been performed by Sylvain Kaufmann (TE-MPE-EM ) on 24/05/2017 in the presence of Marco Ciapetti and Susanne Kuehn. The results are positive:
Even though the resistance to ground vary from tile to tile, it was always 108 ≤ R ≤ 109 Ω
Variation is caused by the cleanliness/dirtiness of the floor: in the same spot, it has been measured before cleaning ≤ R ≤ 108 Ω, while after cleaning (with a humid tissue) 107 ≤ R ≤ Ω. Measures were in some cleaner spots even R ≤ 107 Ω (best result that the used instrument can measure). On top of the ESD pads, we found similar results (even worse than the floor itself, when the pad was not clean).
