Axoncad engineering company can provide you with BIM services for plumbing, heating and ventilation design for residential buildings, multi-family houses, office buildings, hospitals and renovation projects.

Almost 50% of all companies report using BIM tools for a number of projects [3]. Despite the popularity of these systems, there are a number of factors that hinder their widespread use.

The use of BIM requires a lot of effort in creating the initial structure in advance of the project. There are two reasons for this:

1. BIM software is more complex than traditional CAD systems. Some believe that they need a completely different vision of the virtual design of buildings. Professionals who are used to working with traditional two-dimensional or three-dimensional CAD systems may have difficulty switching to BIM programs. The new workflow that will be required to use BIM will become accustomed to designers who monitor the latest state of the art, as well as practitioners who have recently been trained in new design tools.

2. BIM programs require the input of such a large amount of information that the average designer can become tired of this process. To accurately calculate the thermal properties of a building, you must enter many accurate values. If you do not enter all the data or enter it incorrectly, the thermal analysis will not be performed correctly. BIM programs are introducing more and more “model validation”. These functions convey data to the end user on the quality of the information about the model, but are far from reliable.

BIM programs allow changes to be made to the data in an easy way, so the parameters can be changed later in the project, affecting the construction costs and the project. The parametric concept of BIM programs allows you to easily transfer the data that is distributed along the chain to other models and analysis tools. This can lead to confusion, problems with non-parametric tools, as well as problems coordinating elements further down the chain in the building’s functional cycle.

BIM files are larger than regular CAD programs. In addition, BIM systems process more complex and extensive information than standard 3D CAD models. Therefore, BIM tools require hardware with a higher data processing speed and more RAM. Many complex BIM programs only work on computers with a 64-bit operating system and at least 8 GB of memory. Such computers are much more expensive than regular office computers.

BIM programs require the ability to represent three-dimensional systems and clearly see the final result even before design begins. Both novice and experienced users of BIM systems must complete mandatory training for these programs. Since BIM systems are relatively new, good courses are rare and usually expensive.
