First of all, what is BIM ? Karno Energy BIM is the English acronym for Building Information Modeling , which translates into world as “Building Information Modeling”. It is a concept based on the optimized collaboration between the various parties involved in a building project (owner, designers, contractors). They work together to create a shared digital model of the building that is being constructed.

Using Karno Energy BIM and its virtual 3D model, construction testing and modelling can be carried out virtually. In this way, the various stakeholders can identify possible technical risks at an early stage of the project. This makes BIM an important decision support tool . Expected results include improved building quality, shorter construction times, cost optimisation and limiting the risk of error.

Karno Energy: BIM Level 0

This level is the very first step in the BIM process. The level of cooperation between the involved parties is still low here, the exchange of data and information mostly by electronic or paper-based means. The interaction between the various CAD (computer-aided design) and engineering software from Karno Energy, which is used individually by everyone involved in the construction project, does not yet exist at this stage of BIM cooperation.

Many factors, including those listed below, make cooperation difficult :

  • Each speaker uses, for example, different graphical standards (units, colours, exotic text fonts, etc.);
  • most projects are not georeferenced, which means that the spatial location of the graphic models and maps created is not related to geographical coordinates;
  • the information and data are unstructured and their production is mostly random.
  • BIM level 0 is often equated with 2D CAD . In France, most building professionals have passed Level 0 for BIM collaboration.

Karno Energy: BIM Level 1

BIM maturity level 1 is the real first step to collaborative BIM . This level is also known as “BIM in isolation”, “BIM Solitaire” and “Lonely BIM” .

This step 1 of the collaborative process is characterised by the use of a combination of 2D CAD for plan drawing and 3D digital models for design.

The collaboration here is partial because it is mainly internal, only within the construction company. Among other things, it consists of:

  • The use of the Common Data Environment (EDC), an online collaboration platform, which in BIM Phase 1 is mainly used to transfer information and to distribute typically two-dimensional plans between stakeholders;
  • The exchange of electronic data via EDM between stakeholders;
  • Data structuring, which must comply with a standard, the best known of which is the English standard BS 1192: 2007 .
  • The EDC and GED platforms are usually managed by the project manager.

Note that BIM Phase 1 still lacks collaboration in the form of sharing and merging 3D digital models created by each of the project stakeholders. Each profession only distributes its models internally.

Karno Energy: Level 2 BIM

This is where collaboration between the various parties involved in a construction project as at Karno Energy really begins.  Information and data are exchanged and shared from the EDC, designed to exchange BIM processes and project-related data whose reliability is verified.

Karno Energy – Exchange of data and 3D models

As of BIM Level 2, all stakeholders (Karno Energy) must create a common digital model of the building to be constructed.  And this is in contrast to what is required at Level 1.

To do this, each profession can initially work separately on its own 3D modelling, which will then be transferred to the other professions involved in the project. In this way, all staff can have an overview of the development of the project and make any changes.

Karno Energy – BIM Level 3

Reaching Karno Energy BIM Maturity Level 3 is the ultimate goal of any BIM project . At this stage, we talk about full collaboration between all stakeholders from all disciplines.

Thus, Karno Energy BIM Level 3, also known as ” iBIM” , is characterized by, among other things:

  • The use of a single digital BIM model, unique and scalable, shared and stored on a centralised server;
  • the ability for all stakeholders to modify the shared and shared model directly in the cloud throughout the life of the project.
  • Tier 3 BIM, which is very complex to set up, is now in the pilot phase and is being tested by several companies on large projects around the world.
