The Stage 1 layout can be used for discussion
with authorities for formal approval. In moving to
Stage 2 it is necessary to take account of local
regulations, which not only vary by country but by
region within a country. Thus regulations regarding
height, site coverage and fire regulations will require
local expertise and excellent communication with
the relevant authorities. On the completion of the
Stages 1 and 2, the design can now considered to
be 95% of the final design.
