What is 4D BIM and how to associate the “time” property to a BIM model object

4D BIM: let's see how a technician can analyze and monitor project timing and execution thanks to this powerful tool

As we know, BIM isn't a tool, but a process based on a digital model containing all the information concerning the entire life cycle of a building from the design to construction phase leading through to demolition and disposal.

A series of processes that facilitate collaboration between the various roles involved in the different phases of a structure's life cycle.

One of the many advantages of using BIM is that we can continuously update the information model with new data, offering greater degree of detail (read our previous articles: "The dimensions of BIM" (part 1) and “The 7 dimensions of BIM“ (part 2) ).

4D BIM adds even more information to the model: it can provide additional project management tools too optimize planning and timing during execution of works.

The fourth dimension of BIM (4D BIM) brings project management to a whole new level allowing the design team to analyze and monitor construction timing and execution in order to coordinate the various construction resources and tasks.

The advantages are obvious in terms of viewing and optimizing construction site activities already in the design phase such as:

  • verification and optimization of project execution and timing
  • verification of any critical overlapping tasks
  • the possibility to simulate and assess different scenarios and solutions.

The new 4D BIM environment, implemented in Edificius allows the user to analyze construction site phasing by linking up the individual BIM objects or groups of objects to a "time property". A temporal correlation between each task to simulate the entire construction process by means of a timeline and consequently optimize their timing; an efficient tool for avoiding interferences between each discipline present on-site.

How to optimize planning and project management with Edificius

The specific GANTT environment in Edificius is now accessed by means of a new tab in the integrations menu. It includes various 4D management tools to easily configure a timing task bar for each BIM object used during the modelling process.

Simple to use tools in just a few steps.

The Edificius GANTT environment is organised into two main areas where at the top you have the entire 3D model and at the bottom the GANTT diagram with its timeline and animation functions.

The panel on the right hand side contains the "GANTT tools" section where other object related functions can be activated for simulation purposes.


4D-GANTT environment interface

Here we can create the GANTT structure by adding a given activity and assigning an appropriate name (then define a start date and a duration). If we repeat this process for each object or group of objects, we then obtain a project WBS (Work Breakdown Structure). Each elementary period is connected to the realing objects by means of Drag & Drop operations; an intuitive user-friendly working method widely used in Edificius and many other ACCA software solutions.

This simplified workflow speeds up object to time-period linking, especially when connecting groups of objects even in 3D view too. In fact, from the "GANTT toolbox" we can quickly identify objects and drag & drop them to their relating time-period.

Once each BIM model object is completed with its fourth dimension info, we can move on to a construction phase simulation with integrated animation tools with impressive visual impact when launched with the“Real Time Rendering”engine.
