The design and construction industry continues to move more and more into the Building Information Modeling (BIM) realm, with benefits ranging from fast delivery, reduced costs and an overall efficient process. But sometimes, there’s a concern that owners don’t always understand BIM, the data or the costs involved, according to a recent post on the BIMhub.
According to Tuan Tran, northeast regional technical advisor for Guardian Industries Corp., resistance to BIM adoption from owners and others in the building team comes from BIM not providing a high level of product detail and performance energy data.
“They need a streamlined, accurate process for producing and viewing custom, project-specific glazing makeups in 3D with the energy performance data in real time early in the design process,” says Tran.
The Associated General Contractors of America (AGC) hosted a webinar recently to discuss how contractors and others in the construction industry working with BIM can help convey that level of understanding to owners. Joe Eichenseer, director of Building Lifecycle Solutions at Imaginit, led the discussion.
Eichenseer explained that when looking at information in a building model, identifying what’s important to the owner, contractor, designer, it’s the data. “It’s information that we care about,”
He said that in the early design stages, the vast majority start as graphics. Then, as we move from design further into construction, that balance (graphics to object data) starts to become more even.
“Then by the time we get into operations, I would argue that the amount of graphic data should be less than what you have working through construction or design,” he said. “By and large object/text-type data becomes much more important than graphics used to generate it. It’s not the graphics as much as the information that’s what counts.”
So, when it comes to the information needed by owners, what are they specifically looking for? Eichenseer said there are three questions to consider.
1: Space management.
2: Assets management.
3: Work orders.
