1. Previous Minutes

2.1) Grills won’t be added to the doors; alternative arrangements need to be made for air input to the 18kV cell area. One possibility is to take air from the “safe room”, but the routing for the ducting is not clear. Another option would be to add an hole in the wall to the corridor and fit a fire damper.
3.2) The extra input has been added to the two PDUs in the machine room.
3.3) There has been no progress on blocking these cable passages. Little progress is likely no since Wouter van Baaren will be leaving by the end of April.
3.6) TIS Noise in machine room OK.
4.2) Provided. Needs some work. Need clearer phasing of the upgrade now. Need last possible date for various stuff. ST could pay some, but cash flow problem.

2. Substation Status

Belloni have completed the civil engineering work. Schulthess have one barrier section to install; this is now in fabrication.
The transformers have been ordered and are scheduled to arrive in mid-May. The housing has been chosen to meet the needs of the potential barn upgrade. The LV switchboards will arrive in June.
Installation of the general services is somewhat delayed, but there is no problem for the overall schedule provided work starts by the 1^st week of May.
The HVAC specification, including the electrical part, has been circulated for comments.
Anne is now preparing the price enquiry for the “critical” UPS and also the details for the 48V supply as she is now responsible for the overall contract! The 48V installation will be later than foreseen, but this should not impact the commissioning date.

The machine room switchboards have been ordered. There may be a need to store these in B513 as construction will start by mid-June and some will be ready well before possible installation.

The normabarre layout in the internal networking area has been agreed. Anne will now ask for a quote with the intention to have work starting in the 1^st week of September, even if not all normabarres can be removed immediately.
Duct installation work can start from September. Jukka will review the installation of normabarres on RHS and possibly propose modifications for the LHS to increase the possibility of later duct installation. The HVAC work must also cater for the cooling needs in the modem room.
The ceiling under the plenum will be redone once the ducts are installed in the LHS
As there are 3 UPS modules, the machine room PDUs will have to be distributed across these. This will have some impact on equipment installation as it will not be possible to use all the capacity of all PDUs connected to a given UPS switchboard.
