ABSTRACT
The use of 4D CAD has increased in the indus-
try and 4D simulations have been implemented in
growing number of projects. Currently the projects
utilise 4D as a planning review tool, rather than
integral to the initial construction planning proc-
ess (Zhou 2009). It appears that planning is done
as earlier but the outcome in relation to schedule
is presented also in 4D. Now that the technologi-
cal maturity of applications has increased, the
4D technology is able to prepare the way to new
project management tools.
