The document discusses the evolution and benefits of 4D BIM in construction scheduling, highlighting how technology improves the accuracy and effectiveness of construction schedules. With the integration of time dimension into 3D models, building professionals can better plan and manage resources, reducing the risk of obstacles during construction. Additionally, early project decisions facilitated by powerful scheduling tools prevent costly changes during execution.

1. 4D BIM: Get effective information on time and develop
functional schedules
Development of construction schedules is not a totally new concept in building process, but over
the years there have been drastic changes into their functionality which is majorly due to the
advancement of technology. In other words development of construction schedules always
prevailed for construction projects, but their authenticity, validity and effectiveness could be
questioned, since high end technology that can measure and interpret information effectively was
missing. But with the emergence and adoption of Building Information Modeling, all the major
challenges concerning scheduling are effectively tackled by design and construction
professionals.
BIM enabled the development of digital models which are always very accurate and informative.
The addition of new dimension to 3D which is time, allowed AEC professionals to develop
effective construction schedules. BIM modeling services have the capacity to provide architects,
engineers, contractors, owners and fabricators etc a plethora of information which can tackle all
kinds of construction problems in the design phase itself.
Effective schedules developed with the assistance of 4D modeling services can help building
professionals in project planning and construction. Since schedules provide crucial data related
to actual construction activities such as beginning and accomplishing dates of various
construction modules, contractors and other key building professionals can successfully prepare
for day today activities. Preparing for day today activities means effective arrangement of
materials, resources and equipments on right time in the actual location which can help in
making the final process obstacle free. 4D BIM modeling also assists construction professionals
in developing construction simulations which show complete details about the actual execution
of the process in the proposed location and it can assist them in taking effective project
decisions. All those activities which can cause hindrances to the project can be controlled by
taking effective decisions during early design phase. When project decisions are taken during
preconstruction stage building owners don’t have to spend any extra amount of money for
controlling project outcomes. But if changes are made onsite project cost can increase
drastically.
Last but not least with the assistance of construction schedules, AEC professionals get to know
all the details about project completion.
