What is LOD 500?

LOD 500 is a fun one 😅
On a typical project we start with an idea, propose and coordinate with others, go build it and then operate and maintain everything for the life of the building.
The example below (from Trimble) shows a Building Information Model (BIM) progressing with more elements, more detail, and also maybe more maturity, reliability, accuracy, information - you get the idea.
As we move from left to right it's more more more:
The concept of LOD 100 through 400 can help us to define that project progression - however...
LOD 500 has been more difficult to define and understand.
Should LOD 500 define the requirement for more elements, more geometry, more accuracy and more information?

What is BIM?

Image
Building Information Modeling   (BIM) is a set of technologies, processes and policies enabling multiple stakeholders to collaboratively design, construct and operate a Facility in virtual space. As a term, BIM has grown tremendously over the years and is now the ‘current expression of digital innovation’ across the construction industry. It is an intelligent 3D model-based process that usually requires a  BIM execution plan for owners, architects, engineers, and contractors   or construction professionals to more efficiently plan, design, construct, and manage buildings and infrastructure. When I was at school…   my technology teacher Mr Ormrod taught me all about the benefits of building prototypes. I learnt that building something quickly at low cost before actually building it at full scale would save time and money. In most other industries, such as manufacturing cars or phones, they make many prototypes all built and rebuilt to perfection before production is even st

BIM Challenges - The Top 10 "Evil BIM"​ List

Image
BIM is essential for improving our industry's efficiency however when BIM is not implemented correctly teams can experience some severe BIM challenges. We call these challenges "Evil BIM" 😊 Evil BIM is: 1. Owners Just Requesting "BIM" When  an  Owner requests "BIM"  without understanding what they're asking for - solely because a technology vendor has promoted never ending BIM benefits. 2. Not Enough BIM When  not enough BIM  is authored and  BIM Uses can not be completed thoroughly  - for example: proactive coordination, accurate quantity takeoff or the perfect 4D schedule. 3. Too Much BIM When  teams produce more BIM than can be used  by the customer/end users - doing anything that's not needed is wasteful (and evil 😉). 4. Unclear Model Element Authors When project teams are unclear about what BIM they should be modeling and sometimes  incorrectly model each other's scope  ( who's supposed to model the
