Description
The ALICE experimental area management team faces various challenges when it comes to
sharing scarce resources, indispensable to any efficient installation in a category
one worksite. Space, cranes, jigs, and personnel with key competences have to be
carefully allocated to activities so as to avoid slowing down work progress. To this
intent, a resource loaded planning has been developed that allows highlighting
coactivities and prioritizing critical tasks. It uses the built-in capabilities of
Microsoft Project. The use of this scheduling tool leads to a more efficient use of
time and a safer work environment. The installation sequence resulting from this
schedule is presented in this paper. The first part of the sequence focuses on the
revision of the coils in the SX2 building. The dipole has then to be installed in the
RB26 side of the UX25 cavern. This complex and resource intensive activity has to be
performed in parallel with the services installation inside the L3 magnet. On the
RB24 side of the cavern the shielding foundation has to be built. Its design includes
the installation of pre-cast concrete slope modules to allow LHC quadrupoles to be
lowered and taken into the tunnel. This additional constraint on the already busy
schedule of ALICE makes it crucial to plan all activities taking into account the
resources they require. The key milestone set as a goal is the beginning of the field
mapping of the ALICE magnets which are scheduled to start on 21 July 2005.
