• Ressources: • Applus : 2 engineers & 2 technicians
• CERN : 1 engineer, 1 technician, 1 crane operator (punctual, first 2 days) and 2 alignment specialists (1.5 days)
• Starting conditions: Tooling unpacked and pre positioned
Day 1: unpacking, wiring, pre- alignment
Day 2: alignment, floor drilling
Day 3: floor drilling, grouting
Day 4: grouting, wiring review
Day 5: control tests, cleaning
Issues:All went as planned except for a few issues:
• Alignment with the floor plates junction -> bench moved by 25mm
• Surface roughness of the rails: polished by hand
• Communication problem with one of the winches: electric, PLC or software issue to be solved.
