progress planners make use of 2D
drawings and integrate it with their
corresponding component schedules
in GIS software [3].
New advancements in GIS software
help planners in depicting real world
components. Reference [4] explored
the uses of GIS for CPM scheduling.
Using 3D models and CPM schedules
as inputs, linkage between the two
has been made possible in GIS to
develop a 4D model. Reference [5]
suggested that GIS acts as a platform
in which both spatial and non-spatial
data, that is, drawing components
and their activity schedules, are
integrated for successful execution
of the project by providing good
visualisation.
Advanced visualisation techniques
such as 4D (3D geospatial + time

component) and virtual reality
should be utilised for more effective
evaluation and communication
of construction project schedule
information. Therefore, it becomes
easy to find errors in schedules,
and small activities can also be
completed without any delay. This 4D
GIS view provides better visualisation
progress of a construction project
and makes the planning sequence
and execution easier to understand
and allows a planner to visualise the
construction process in the way it
would actually be built [3].
Comprehensibility in the project
schedule will decrease the potential
errors and conflicts in the schedules
during the construction. A building
plan with the corresponding themes
