impact of 4d modeling on construction planning process - Chalmers ...

separately the updating task <strong>of</strong> the model becomes hectic and time consuming as the
whole procedure needs to be repeated again.
The temporary structures should also be added into the model for enhanced spatial
configuration and to evaluate the constructability and safety issues to maximize the
efficiency <strong>of</strong> the planning. To ensure that the 4D <strong>modeling</strong> process executes
smoothly, different project teams involved in the project should use inter compatible
s<strong>of</strong>tware tools. Like the 4D tools usually require the 3D model to be imported
separately from some other 3D <strong>modeling</strong> s<strong>of</strong>tware tool. So the 3D model should be
developed in a s<strong>of</strong>tware tool which is supported by the 4D tool being utilized on the
project. This also implies for the schedule if it is being developed in a separate
platform and then imported into the 4D tool afterwards.
The reliability <strong>of</strong> 4D planning can be improved by involving as many project
participants as possible in planning phase. The planning process can learn from
Integrated Concurrent Engineering (ICE) design process where all the design teams
work together at the same time and same place. ICE enables multiple, simultaneous
information flows with short lead time and high level <strong>of</strong> service (Chachere, Kunz, &
Levitt, 2009). With the contribution <strong>of</strong> different project teams working together in the
planning process, the 4D model can be developed which acts as an effective
communication framework to generate a more reliable and efficient construction plan.
Furthermore, for enhancing 4D planning, another vital requisite is to employ high
skilled and experienced staff. The reason is that without knowledge <strong>of</strong> 4D <strong>modeling</strong>, it
is impossible to build it up properly or it would be time and cost consuming. That is to
say, planner should be the one who has enough knowledge and ability to carry on the
work. Therefore, top managers <strong>of</strong> a construction project implementing 4D planning
are recommended to employ potential planners and systematically educate 4D
technology to them. Training programs should be organized regularly to ensure that
the knowledge instructed to planners is continuous and up to date. This solution can
benefit both the project and the company in long-term advantages.
