What is 4D BIM?

• 4D BIM is one of the technologies that has found
  importance in the Building Information Modeling
  world.
• It represents building data in form of time line
  featuring duration of construction integrated
  with 3D geometry of building in a simulation
  format. It evaluates the overall design features
  on the construction schedule and workflow.

What is 5D BIM Model?

5D BIM

• 5D BIM represents the costing and budgeting of
  any building that is getting constructing. We can
  extract material take off, quantity take offs,
  list of components with pricing and overall
  schedules using 5D.
• 5D BIM is the process of producing accurate cost
  estimates from the components of the information
  model. The main benefit of 5D cost estimating
  services is it includes all information related
  to the building and its components.

Understanding the Technology

• This technology is extremely useful in the
  pre-construction, construction and
  post-construction phase of the building project
  by analyzing the building information model.
• A 3D BIM modeling gives an additional
  information i.e. four dimensional information
  (time), fifth dimensional information (costs) and
  sixth dimensional information (facility
  management).
• BIM allows the Architects and Engineers develop
  3D digital information model for all type of
  simple and complex building projects.
• BIM model is a 3D database providing end to end
  information related to the building project.

Purpose of 4D BIM Technology

• The main purpose of performing the 4D BIM
  modeling process is to prepare a construction
  task schedule by linking the model elements to
  the timeline.
• 4D BIM creates a simulation video for the
  construction project in 4D environment showing
  every stage of building construction.
• 4D models create virtual mockup of the
  construction system design which identify
  work-flow based clashes and also manage the
  supply chain for materials and labor required on
  the construction site.
• Virtual mockups are also known as sequenced based
  simulations which help contractors to communicate
  the complex processes to whole team improving
  overall productivity onsite.

Purpose of 5D Technology

• The 5D modeling process adds cost information in
  the 3D model. The cost data is integrated within
  the BIM model objects themselves.
• The 5D BIM modeling helps to create a
  relationship between elements and include the
  properties and specification of each element and
  object where we can extract complete and accurate
  information from the model used for costing.

Finally.

• 4D and 5D BIM modeling process assists the
  engineers and architects to detect and resolve
  schedule clashes.
• Schedule clashes mainly occur when the schedule
  for two or more tasks is wrongly arranged at the
  same time.
• If any kinds of modification are made within the
  design, the project task schedule and cost
  information also gets automatically updated
  according to the modified design. Thus 4D BIM and
  5D BIM assist the engineers to prepare a project
  plan and estimate project costs efficiently.
