--- BIM MODELING ---------------------------------------------------
2D -CAD DRAWING
The 2D dimension is the oldest form of building models. It constitutes a simple X axis and a Y axis. These models are generally made by hand
through manual processes or through the use of CAD drawings.
3D - ARCHITECTURE AND ENGINEERING
3D BIM Dimension (The Shared Information Model)
3D BIM is arguably the most popular BIM dimension that all construction companies are familiar with. It is also known as the coordinate model.
3D represents the three-dimensional geographic structures of a building, that is, the X axis, Y axis and Z axis of a building.
BIM 3D involves the creation of graphical and non-graphical building information for the sole purpose of sharing it in a common data environment (CDE).
3D BIM models are used for schematic designs, design development and documentation, construction documentation, and registration drawings.
By using 3D BIM, you will be able to keep your workers up to date on the latest design trends.
What are the benefits of 3D BIM dimension?
Visualization: Throughout the entire project, 3D BIM would give you a full three-dimensional visualization.
Helps to check possible collisions.
Promotes communication between workers.
Guarantees transparency throughout the project.
Create a detailed model of the impact the project would have on the environment.
4D - TIME AND PLANNING
Construction time estimation and planning is essential to optimize resources during the construction phase.
In fact, it is always recommended, if not mandatory, to prepare the schedule of the works, the Gantt and Pert chart, etc.
for the management of the duration of a construction project or, more generally, of a commission.
These traditional methods, however, do not contemplate the possibility of reducing/managing/reorganizing the order time in a dynamic and open way.
For clients, designers and contractors it would be useful to be able to "visualize the work" already during the design phase, in order to predict and plan all activities based on time.
BIM, and in particular BIM 4D modeling, can be the solution to these demands and can represent a valid support to reduce delays and inefficiencies in the work.
4D BIM modeling is the process that creates intelligent connections between the 3D digital model (which defines the geometry of the work) and the information related to the
execution time of the different activities necessary to execute the work.
5D - COST ESTIMATE
Traditional estimating budgeting requires time, precision, and attention. Often it is also necessary to manually update it as
that project options change, with the risk of increasing the probability of errors.
5D BIM modeling makes these operations faster and safer, as it automates cost estimation processes, calculating quantities
directly from the BIM model.
5D BIM modeling is the process that creates intelligent connections between the 3D digital model (which defines the geometry) and the cost information.
of construction of the work.
With a BIM model available, cost estimation can be done automatically, since the prices of each process or supply are associated
directly to the parametric objects of the 3D geometric model.
