Current construction process planning is done using scheduling
and schedules in Gantt Charts. Whilst the project managers can follow
these complex maps, they are not particularly good commucation tools
for those unaccustomed to them. With the more collaborative way
of working today, building trust through communication is invaluable.
In many cases, problems in any complex project stem from the owners
misconception of reality. This is typical in construction. It is
difficult to explain the interrelationships of forces and construction
elements using two dimensional drawings, particularly in the case
of multi-storey buildings.
4D Construction Plan Models
A 4D model combines a 3D model with scheduling data. A 4D model
can be used to:
increase the quality of the process plans
build better models and simulations of the construction process
duration of the projects
maintain certainty that the schedule is realistic
communicate progress and issues between stakeholders
To automate generation of 4D models computer applications with
reasoning engine[s], together with construction operations knowledge
are able to interpret 3D geometric data and produce a process plan
showing exactly how the building can be constructed.
A linking approach can be sued to create dynamically linked 4D
models. This provides for the updating of schedules and designs
without the need to recreate the 4D model every time a change is
made. Done in this way, the use of the 4D model adds little additional
expense to the program budget.
Both VTT and Eurostep have developed a tool that can create a dynamic
and real-time link between 3D IFC model and a schedule. 4D Tool
development was partially funded by DIVERCITY.
