Turning BIM Models Into Buildings

December 13, 2010

I have written in the past about the various aspects of as-built construction and the construction process that can’t (and shouldn’t) be represented in a BIM model. While there are countless articles, blog posts and Tweets covering the wonders of BIM in the weeks and months leading up to construction, you never hear any stories about the experiences of the construction managers, consultants and project managers who interact with the model once construction begins.

I am curious to hear about the experiences of others who have ground-level knowledge from BIM projects.

  • How has BIM affected the number of RFI’s that you would normally expect for this type of project if it had been designed using traditional methodology?
  • Are there certain types of RFI’s that prevail despite the use of BIM?
  • What types of issues do you experience when updates to the BIM model become necessary?
  • Where do you see gaps when comparing the BIM model to As-Built conditions on your project?
  • What has surprised you (good and bad) about building to the BIM model?
  • Has BIM had an impact on your coordination or sequencing efforts?
  • How have you utilized the BIM model for regulatory compliance?
  • What will you differently on your next BIM project?

4D 5D Can’t Complete the Picture

July 29, 2010

For all the promise of 4D and 5D BIM technology, users can never capture the reality of jobsite conditions and their impact on a building.  Yes, including the dimensions of time and cost adds a stronger connection between design and construction. But there are many components of “as-built” construction that BIM can never capture. There are certain conditions that can only be accurately and comprehensively recorded in photos and video.

Here’s a partial list of conditions and I welcome you to add others:

  • installation processes
  • access issues
  • sequencing issues
  • use of specified materials
  • fabrication processes
  • water intrusion remediation
  • LEED point qualification

Finally, before you convince yourself that as-built conditions can be completely represented in a BIM model, remember that human beings are the connection between the two.
