  Forbidden in the Standard Model, Charged Lepton Flavour Violation is a strong
probe for New Physics. The COMET Experiment will measure one of these
processes: that of COherent Muon to Electron Transitions, where a muon converts
to an electron in the presence of a nucleus without the emission of any
neutrinos. COMET aims to improve the current limit on this process by four
orders of magnitude. Being built in two phases at J-PARC, Tokai, Japan, COMET
will first take data in 2018, where it should achieve a factor 100 improvement.
This report gives an overview of $\mu$-$e$ conversion and the COMET experiment
as well as a summary of the recent progress in construction and design.
