5 What is BIM?

6 BIM Defined as a Product Physical (Geometry) Characteristics (Information) A Building Information Model (BIM) is a digital representation of physical and functional characteristics of a facility. As such it serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward. National BIM Standard Definition

7 BIM Defined as a Process Building Information Modeling (BIM) is... a new approach to design, construction, and facility management...bim is not a thing or a type of software but a human activity that ultimately involves broad process changes in construction. (BIM Handbook) a process focused on the development, use and transfer of a digital information model of a building project to improve the design, construction and operations of a project or portfolio of facilities. (BIM Project Execution Planning Guide)

8 Some other terminology 4D CAD (3D + time) - Adds temporal dimension for construction process visualization nd Adds any/all attribute information (e.g., cost, material properties, etc.) VDC Virtual Design and Construction IFC Industry Foundation Classes, is a vendor neutral, open data exchange specification. Parametric - Rule based relationships between intelligent objects that enable related properties to be updated when one property changes.

9 There are many BIM applications... Design/Engineering Autodesk Revit Bentley Triforma Tekla Nemetchek All Plan Rhinoceros Graphisoft Many will co-exist on the same project. For a more complete list of software, refer to the BIM Handbook. Integration Navisworks Innovaya Rhinoceros Tekla 4D Modeling/ Construction Management Navisworks Synchro Tekla Vico

10 Evolution of BIM From lines and meshes To 3D graphical models To 3D object models To 3D parametric models

11 The power of parametric modeling The entire building model and complete set of design documents is an integrated database, where everything is parametric and everything is interconnected. Source: Autodesk White Paper, Parametric Building Modeling: BIM s Foundation

13 The big idea Interoperability View

15 Why BIM?

16 Documented benefits of BIM Improved communication Improved coordination Increased productivity Greater prefabrication Elimination of field interferences Less rework Fewer requests for information Fewer change orders Less cost growth Shorter construction period...

24 Example: Laser Scanning to BIM for Existing Buildings Capturing accurate as-built data manually is expensive, time consuming and error prone. In contrast, with 3D laser scanning technology, models of existing buildings can be created to 4mm accuracy in a matter of hours much more cost-effectively and without disruption to the users of the building. While these are not BIM models as such, they can at least be used for 3D coordination to reduce RFIs, errors, and omissions and provide the correct site context for new projects. Figure 4.

26 Some other BIM Drivers Owner Requirements GSA: All major projects that receive design funding in FY2007 and beyond are required to submit a spatial program BIM to GSA State of Wisconsin advances BIM requirements for government contracts State of Texas adopts BIM requirements U.S. Army Corps of Engineers requires BIM on all projects Alberta requiring BIM on all projects starting in 2012 UBC is requiring BIM on more projects Green Buildings LEED requirements (e.g., waste, energy analysis, etc.) More experienced BIM users also tend to be more heavily involved in green projects than others. (McGraw-Hill 2009) More collaborative project delivery methods Integrated Project Delivery

27 Deep usages of BIM require deep collaboration A basic premise of BIM is collaboration by different stakeholders at different phases of the life-cycle of a facility to insert, extract, update or modify information in the BIM to support and reflect the roles of that stakeholder. (National BIM Standard) Integrated Project Delivery (IPD) is a project delivery approach that integrates people, systems, business structures and practices into a process that collaboratively harnesses the talents and insights of all participants to optimize project results, increase value to the owner, reduce waste, and maximize efficiency through all phases of design, fabrication, and construction.

35 How to BIM? (this is where things get really interesting...)

36 Some Critical Questions for BIM Projects How will the BIM model be used? Design coordination? Design analysis (e.g., structural, energy)? Construction coordination? Fabrication? How do you organize BIM Projects? How should the team be formed? When should different team members come on board? What types of contractual relationships? What type of incentives should be used? How do you set up modeling requirements? What will be modeled? Who will model? When will systems be modeled? How will they model? How will progress be tracked? How will change be managed? How do you measure the impact (value) of BIM? Cost savings? Time savings? # of change orders? #of RFI s?

38 Some useful references

39 AGC Contractor s Guide to BIM Whether the design is issued in the form of 2D printed documents or a 3D electronic media or in a combination of both, the responsibilities of the members of the project team remain unchanged. The important issue is to ensure that project team members thoroughly understand the nature and exactitude of the information that is being conveyed.
