Q: We hear a new software is being used more and more in healthcare project design. Roger, what is BIM?
A: "BIM is a cutting edge technology for computer aided design known as Building Information Modeling. Called "BIM," this new tool uses three-dimensional, real-time, dynamic building modeling hardware and software to increase productivity in building design and construction. Some top cited benefits of BIM are: easier project coordination; improved project team productivity; improved communication; and improved project quality control."
Q: How is BIM different from CAD?
A: "At its basic level, BIM represents a change from traditional 2-D drawing to a dynamic 3-D model built around a database of a project's physical and functional characteristics. The more data input into the model the more benefits that can be gained from it. The model includes building geometry, spatial relationships, geographic information and quantities and properties of building components."
Q: But what does all this mean for healthcare design?
A: "At our firm IKM Incorporated, all new projects are designed with BIM software. This software facilitates designing all elements in three dimensions. It enables systems and assemblies to be shown in a relative scale within the entire facility. Modeling provides representations of the actual parts and pieces, called "intelligent objects," used to build a building rather than drawing lines that combine to represent objects. Once placed in a building model, these intelligent objects are automatically represented in any plan, elevation, section, detail, rendering, or even a maintenance plan."
Q: As a healthcare professional, where do I see the benefits?
A: "The model is where we see the benefits in healthcare design. We are able to share a three dimensional model with the client much earlier in the process. This helps the healthcare staff at all levels to better understand what is being designed and proposed for their new space“ the staff can visualize how much space is between the handwash sink and the patient bed, for example. It is very effective. "
Q: So, BIM provides powerful visualization capability. You mentioned that IKM is using BIM to communicate design intentions to all parties by taking advantage of its 3-D visualization capabilities.
A: "Previously, we presented projects primarily with 2-D images and occasionally a perspective drawing. If you don't look at plans every day, they can be difficult to read. Now with BIM, you can see just how large a window is going to be, and where the placement of the fixtures may occur in the room. It makes it much easier to convey the design intent."
Q: Are there other benefits to using BIM?
A: "Using BIM enables the architect and engineering design team to produce a single model. This means each team member (electrical engineer, structural engineer, plumbing engineer, and so on) adds their own discipline-specific knowledge and the model tracks the changes. By working on the same model, the design team realizes greater collaboration and communication in the early stages of the design process. This increases coordination between disciplines and results in fewer conflicts between trades during construction."
Q: So, its like building a 3-D model and everybody is working on the same puzzle.
A: "The software allows the use of conflict detection where the computer actually informs team members about interrelated parts of the building through detailed computer visualization of each part in relation to the total building. For example, MEP engineers can detect where duct work or plumbing might conflict with the structural systems. This capability allows the design team to collectively resolve issues during design reducing contentious, expensive and time-consuming conflicts in the field during construction. "
Q: Any last comments?
A: "IKM has used this software on minor renovations in hospitals and on the design of a new 100,000+ square foot specialty hospital in Ohio. We're still learning all of the benefits the software brings to the design process. Overall, we believe that BIM is driving an unprecedented revolution in the building and design industry transforming the way projects are designed, built and managed."
