1 General description General description of the tasks to be accomplished Each Muon Station is composed of two parts: one on the Cryo side (US), the other on the opposite side. The detectors are mounted on Aluminum support walls. There are five Muon Stations and ten support walls, one on each side and for each station. Each wall is constituted of five aluminum panels, which have maximum dimensions (in station M5): H 2080mm x L 6180 mm x T 24 mm and maximum weight 260 kg each. The first (top) panel of each wall will be fixed to a lifting system, while the following panels (2-5) will be glued and riveted on the previous one. The installation will be accomplished in two main steps, described in the two “Fiche de tache”. The personnel from INFN will participate to the work in groups of about 4 persons, organised with shifts.
