National BIM Standard Definition - 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. 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. The BIM is a shared digital representation founded on open standards for interoperability. The US National BIM Standard promotes the business requirement that this model be interoperable based on open standards. If business processes are changed the following benefits have been demonstrated: Better visualization by the Owner Elimination of conflicts, RFI s and change orders Significantly faster project delivery times Elimination of construction drawings and going straight to shop drawings Numerical controls passed directly from the model to fabrication Data collected during design & construction used for operations, sustainment and contingency planning Information flows when standards exist 2

Earlier Decisions are Less Expensive BIM modeling costs vary based on several factors: Purpose of modeling effort Phase of project design Level of detail of the model Number of updates to the model As rule of thumb BIM modeling will range between.1% to.5% of the project construction value Conservatively BIM can save projects 3% to 5% of the construction value 6
Overall savings in MEPF coordination of $184,940 as a result of shorter meetings and reduced downtime from travel Avoidance of 450 RFI/COs through model constructability review Average cost of major change order is $10k means a cost avoidance of approx. $4,500,000 Cost of modeling the Ritz Carlton approx. $285,000 Modeling ROI = $4.4 Million BIM Project Execution Planning Guide This BIM Project Execution Planning Guide is a product of the BIM Project Execution Planning buildingsmart alliance (bsa) Project. The bsa is charged with developing the National Building Information Modeling Standard (NBIMS). This guide was developed to provide a practical manual that can be used by project teams for designing their BIM strategy and developing a BIM Project Execution Plan. The core modeling and information exchange concepts are developed to complement the long term goals of the bsa in the development of a standard that can be implemented throughout the AECOO Industry to improve the efficiency and effectiveness of BIM implementation on projects. The Model Progression Specification Identification of the BIM author (also referred to as the Model Component Author). It should be noted that in the early phases of a project, BIM objects may be created by one party at a lower LOD as a placeholder, and at later phases, then may be replaced by a higher LOD object created by the party responsible for the actual design. A description of the file formats used by the modelers to deliver the BIM, as well as the software applications and their version number used to create the BIM. A description of the appropriate uses (and decisions) that can be made based on the project phase and LOD of the BIM. A description of what LOD a particular BIM object is required to use for a particular phase of the project. A description of the Level of Detail (LOD) for model objects based on UniFormat assemblies. There are five defined levels of detail for BIM models (defined as 100, 200, 300, 400, and 500). 7

Not only can the BIM model provide accurate visualization of the design intent, but we have accurate information of every architectural element as well as structural & MEPF elements Cut-aways and renderings help client understand construction issues 10
Coordination meetings now taking place via GoToMeeting sessions and Navisworks Subtrades work from their offices Meetings are shorter 1½ to 2 hours vs. 4 to 5 hours in the traditional 2D process PDF digital signatures of coordinated drawings Overall savings of $184,940 as a result of shorter meetings and reduced downtime from travel 11

The vertical work in the 2 pour sequence causes an uneven flow of work between the of work. The 3 pour sequence provides a better flow and completes the work 10 weeks earlier. 2 POUR SEQUENCE 3 POUR SEQUENCE Project Complete 12/31/07 Project Complete 03/13/08 The Swinerton contracted Vico Services to deliver Virtual Construction Services for the 719 Ash Hotel & Residences project located in San Diego, CA. The proposed building contains three stories of mixed use office/retail/restaurant space, 16 stories of guest suites and condominiums, and three stories of underground parking. The structure is primarily cast-in-place reinforced concrete with structural steel supporting the penthouse roof. The exterior finish contains panel and plaster systems, glazed curtain wall and aluminum window systems. This scope of Virtual Construction services on this project is limited to architectural and structural building systems only. Interior construction and finishes are limited to framed walls and ceiling elements, interior doors, and stairs. The project was divided into three phases for delivery. Phase 1: 3D Model, Constructability Analysis, Rendered Images Phase 2: Knowledge Database, Modelbased Quantity Report and Estimate Phase 3: Schedule Optimization and 4D Construction Simulation 13

Prototype Project Target Large and Complex Projects Science Buildings Medical Centers Complex Renovations Establish BIM Standards Engage Facility, A&E, GC and Sub Trade Partners Define goals, uses for the model, integration/change campus processes What are our BIM standards? Who maintains the standards? Who hosts the BIM model? Are the Facility standards loaded into the BIM platform? Is our BIM solution integrated into the Institution s Enterprise system? Should it be? Is our culture capable of greater collaboration, teamwork and sharing of information? 16
