Building Information Modeling (BIM)

The 1970s introduced BIM, a more evolved digital representation of the physical and functional characteristics of a facility. By the 2000s, giants like Autodesk and Bentley Systems had already recognized BIM's potential and began championing it. Where BIM shines is in its collaborative framework during the design and construction phase. It bridges the understanding gap among architects, engineers, and contractors, ensuring everyone is on the same page. This united front translates to numerous advantages: minimized errors, streamlined project timelines, and more accurate budgeting. But, it's essential to note that by design, BIM primarily targets the construction phase rather than the continuous operation and upkeep of a facility.

Evolving from the foundations laid by CAD, BIM augments facility operations with intricate, data-intensive 3D models. In contrast to CAD's limited scope, a BIM model—take a wall as an example—incorporates a comprehensive spectrum of details, from its material makeup to financial considerations. 

Like CAD, there are some key issues when it comes to BIM and the efficiency and feasibility with how it works for the day-to-day management and operations of spaces within a building.
