Rather than plan outfit installation on a total ship system basis, it is
today common practice to plan this work for zone installation, the zone
corresponding to a main compartment area which may e broken down into blocks or
smaller assemblies. Pre-outfitting of each assembly or block may be or the
order of 85-90 percent. Both steelwork and outfit are highly planned for each
assembly and block unit, and fabrication and outfit installation is undertaken
at a work station where the facilities and material are supplied.
