What is BIM?
The Acronym BIM =? Building Information Model or Building Information Modeling
One Common Misconception: CAD = 2D drawings BIM = 3D drawings Not true! With CAD, you can easily create 3D drawings
So What s the Difference? Unlike standard CAD, which is really highly efficient drafting, BIM software involves creating a virtual model that mimics a real building. Ideally this model and its site, if created correctly, will contain all the information necessary to answer any query Source: The BIM (Building Information Model): What is it and where are we going, H. Edward Goldberg, AIA, AUGIWorld, Nov/Dec 2005
CAD CAD vs. BIM CAD elements are purely graphical representations of building components Elements can be tagged with supplemental data Relevance and meaning of elements must be inferred by the viewer from the element s context and from accepted conventions Source: BIM and Process Improvement, Jim Bedrick, Webcor Builders, http://www.aecbytes.com/viewpoint/2005/issue_20.html
BIM CAD vs. BIM BIM elements are simulations of building components The elements know what they are and what their characteristics are Elements can simulate the actual element s behavior Source: BIM and Process Improvement, Jim Bedrick, Webcor Builders, http://www.aecbytes.com/viewpoint/2005/issue_20.html
So What Does BIM do? Modeling Drafting Visualization Animation Simulation Analysis Change management Interference detection Information management Plotting Publishing Collaboration Source: www.bentley.com
For Instance: With BIM, elevations and sections are easily generated. Changes to the model are automatically incorporated. Schedules are easily created and maintained. Models can be analyzed for structural member determination, electrical and mechanical loads, and energy consumption. Cost analysis and component counts can be queried from the BIM.

Cutting Through the Confusion Computer-Aided Design is A tool for project delivery (i.e., AutoCAD or MicroStation are used to create construction documents) While Building Information Modeling is A process for project delivery (i.e., how a team works together to design, build and operate a building)
The Dividing Line
Why BIM?
Study Identifies $15.8B Annual Loss Interoperability problems in the capital facilities industry stem from the highly fragmented nature of the industry, the industry s continued paper based business practices, a lack of standardization, and inconsistent technology adoption among stakeholders. Based on interviews and survey responses, the lack of interoperability costs the U.S. capital facilities market $15.8 billion per year. Of these costs, two-thirds are borne by owners and operators, which incur most of these costs during ongoing facility operation and maintenance (O&M).
Where are these Losses Occurring? Information Value Information is collected during each phase of the facility life-cycle and lost at the handoff points to be partially recollected in many cases at additional cost. The solution is to use a standard framework to collect information as it is generated on a continuous basis. GOAL: Continuous Information Collection WASTE Planning Design Construction Operations, Sustainment Time
BIM is More Efficient for Design

USACE BIM Effort
How the USACE BIM effort took off Realignment/Establishment of Corps Centers of Standardization (COS) memo dated 3/6/06: All 8 COS have to develop and maintain BIM models for each standard facility type A Road Map had to be developed to provide guidance to those sites in implementing BIM.
Overall Reasons Why the Corps Needed to Move to BIM With the current war and economy, the Corps has to find ways to save time and $ because funding is tight. BIM provides the means to succeed With Industry and A-E firms using BIM; moving to BIM is no longer an option for the Corps (as well as other agencies), it is a necessity.
The USACE BIM Road Map https://cadbim.usace.army.mil/myfiles/1/erdc_tr-06-10.pdf
Where We Are Heading with BIM Building Information Modeling U.S. Army Corps of Engineers Road Map Initial Operating Capability (IOC) 8 Centers of Standardization (COS) productive in BIM by 2008 Establish Life-Cycle Interoperability 90% compliant with National BIM Standard (NBIMS) All districts productive in NBIMS Full Operational Capability (FOC) NBIMS used for all projects as part of contract advertisement, award, submittals, construction, O&M, asset management Automation of Life-Cycle Tasks Leverage NBIMS data for substantial reduction in cost and time of constructed facilities 2008 2010 2012 2020..
When We Are Heading to BIM Addresses both Short-term (FY08) and Long-term (FY10) goals Provides Implementation Guidance Addresses MILCON Transformation, Centers of Standardization, and Civil Works Address BIM in Design/Build and Design/Bid/Build
