BIM ELEC - Digital models : The cable routing, a sensitive and strategic issue

Triangle Metier

Going paperless is the first essential step in the digital transformation of companies. It consists in replacing paper documents by digital files or in directly creating digital documents and incorporating them into the different processes. Going paperless also means improved business administration and ease of access to data and documents.

Working with BIM involves providing a model of all the information about a building in a digital model, in team mode. Today, all players can see the interest of pooling information about a building in a shared medium.

All the features of the structure, as well as all other aspects, such as electricity, are listed, providing the owner with the chance to see all the building and networks in 3D all through the lifespan of the building. BIM also highlights potential errors during the design phase. Another non-negligible asset is to include all the electrical equipment, without having to re-enter data, providing an accurate and faster overview of electric output.

This is also the best way to save time, as well as ensuring, from the design phase onwards, that each BIM object (electrical cabinets, cable routes, equipment, etc.) will not interfere with other building elements.

  • Designing the different features of the electrical circuits, for both strong and weak currents
  • Choosing the cable routes and junction boxes that are needed to install and supply receivers
  • Keeping bend radiuses under control and adapted to the rigid or flexible cable used
  • Optimising the best possible cable route, which is sometimes the shortest route, but always in line with the mesh network, and respecting the constraints linked to the installation and/or the sector standards

Carrying out accurate measurements of cables in line with their routes is a subject that shows the strategic interest of including cable routing in the digital model… And so BIM ELEC was born!

BIM ELEC - 2nd article: An added value for the electrician

In part one (see our 1st article), we set the scene. But as active participants in this market, our aim is to look at the operational professions in detail and see how we can help them in the digital transformation of companies. While going paperless is the first essential step in providing better management and easier access to data and documents, in this article we will see the added value it provides to electrical contractors.

BIM ELEC - Digital models : The cable routing, a sensitive and strategic issue

Not a day goes by without electrical contractors discussing BIM. Over time, digital models have become an essential element in exchanges at work. The aim is to take account of the lifecycle of a building from the design to the operational phase, while not forgetting the construction phase, of course.

3 essential levers of action during the design phase

BIM is becoming a vital element in joint work, with a goal of including each stage in a building’s lifecycle:

  • Design
  • Construction
  • Use

 There is no doubt about the relevance of BIM in the first two stages, given the large number of projects using digital models. But there is definitely scope for exploring BIM in a building’s operational phases with its dedicated tools.
