Building 16 and 17 are inside a common environment
with building 153, 162, 18, 173 and 256

• Building 16 is used mainly by PH DT, but also LHCb and some other scattered users (e.g. CLOUD, ATLAS )
• Building 17 is used by AB and PH (1st floor)
• Building 153 is used by PH/DT (assembly hall)
• Building 162 is used by AB and PH (mechanical workshop)
• Building 173 is used by AGEIS, CMS and PH/DT
• Building 256 is used by PH/DT (gas calibration lab, renovated in 2009/10)

In 16 and 17 we have mainly offices with few labs and one meeting room. In 153, 162 and 173 we have labs with workshop and assembly area.
This area is sharing a 40 tones crane and the whole building complex is served by a single heating system and it is an open volume, so noise is shared by all users.

List of urgent renovations need for building 16 and 17 independently of the total area
problematicIn view to have a safe and clean working
environmentInstallation of emergency evacuation lighting.
Building 16 : ground floor and first floor need 2 each.
Building 17: ground floor, first floor and 2nd floor need 2 each.
Total 10 evacuation lamps.
Reparation of almost destroyed water pipes connections (cf picture 1 on following page)

Consolidation of cracks on walls due to crane movement and revision for the maximum load for the crane ( three major cracks identified – two on first floor bldg 16 and one on ground floor of Bldg 16.) the major one is more than 2 meters long and open almost 5 mm!!! Cf pictures7 to 10 on following slides.
Painting of one toilet and reparation of tiles in two toilets.(12m2 painting and 2 m2 tiles)
External blinds reparation or exchange, (10 windows for buildings 16 and 17)
Painting of Copy machine room, bat 16. (10m2)

General problems for Building 16, 17, 153, 162 and 173
• Heating is actually performed by a very old system. Cf picture 4
• Regularly out of order, not efficient and very noisy.
• But very big volume to heat (16, 17 and 153 and 162) and the insulation of the buildings should be reviewed in parallel
• Noise: from heating and heat treatment activity (power supply)
• Cf report at the end

• Water leaks from the roof
• Asbestos dust should be checked
• Bad smell from waste water
