Time To Go In-Depth

Bimcast by Catenda is a podcast series on open BIM and the possibilities of digitizing the construction industry. We will invite knowledgeable and inspiring guests to talk about topics related to open BIM, digitization and open international standards in the world of construction and infrastructure. This series is part of our ongoing efforts to make the construction industry worldwide ready for the work processes and digital flow of the future. Available on all major podcast players.

Ep 8 - What is a good BIM?

The guest in episode 8, which is also the very first episode of Bimcast Season 2, is Frode Mohus. He is in charge of BIM at Statsbygg (The Norwegian Directorate for Public Construction and Property). The conversation with Håvard Bell from Catenda covers topics like how does Statsbygg plan for the new type of BIM model or digital twin that is emerging? What does it take to make a great BIM manual? Does Statsbygg focus on phase per phase or do they plan for the life span? What are the most important requirements to include for the future of BIM?

Do you want to know more about what to think about to get your model just right? Here is a collection of resources that will get you started.

Top tips to make an optimal BIM manual

  • Be exact when specifying the requirement sets so they can be validated in software.
  • Validate automatically as much as possible in order to free time for what still needs to be done by humans.
  • An example: fire rating - there is general fire requirements and a there is a precise property description, use the latter to validate correctly. Specify that there is such a thing as fire rating, make sure you also validate the quality of the data within mvdxml and/or bSDD.
  • Statsbygg divides the BIM manual template into four basic requirement sets, one for each of the main domains: architectural, structural, mechanical, electrical. Then nine milestones are set on the timeline depending for you to validate depending on how far along you are in the construction process.
  • Make a manual template that is flexible, that can quickly change depending on the project at hand.
  • Connect to GTIN numbers and other G1 standards, use databases to find out everything about the product, linking it to the model and at the same time minimising the information size in the model.
