An Overview of BIM standards

The definition of a BIM standard states that building information modeling is: “a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition”.

BIM is making a lot of noise in the construction industry at the moment, and everyone is interested in what BIM can do when it comes to construction and building expos. The history of BIM technologies and ideas goes back 50 years in the past, and it’s still evolving.

The more these technologies evolve, the more innovative solutions they bring along. BIM technologies allow for representing the intrinsic and physical properties of any building by tying buildings, as object-based models, to a database.

can improve the rendering power of engines and make the building of model components much more efficient by optimizing program environment and taxonomy with specific features.
Every time a change is made in the model during the project development phase, all changes and project drawings correspondingly adjust to all the updates and upgrades.

First international BIM standards

have been published by the International Organization for Standardization (ISO). These new standards include:

• Part 1: Concepts and Principles
• Part 2: Delivery phase of the assets

These are the new standards of ISO 19650, and they refer to digitization and organization of data about civil engineering works and buildings, including BIM. ISO 19650 is based on two British standards:

• BS 1192
• Public standard PAS 1192-1

Both standards significantly contributed to reducing user construction costs. According to ISO, these new global standards are aimed at providing a more effective framework to help contractors and designers by making their collaboration more efficient, improving all phases of construction.

Part 3 is on its way, and it will be focused on managing the operational phase of assets while Part 5 will deal with asset management, digital built environments, and BIM security.

There’s a massive potential for BIM in industries like construction, engineering, and architecture. In fact, these industries have been increasingly integrating BIM technologies for digital construction and virtual design due to its amazing features like generative design, cloud computing, augmented reality, human-computer interaction, and sustainable design practices.

The trend of integrating BIM across different industries is affecting the process of the evolution of BIM. The more these modern and advanced building information modeling technologies continue to develop, the more industries will witness the rise of the construction tech that will change the way we design, develop, build, and construct.
