1 Overview Building Information Models
National Institute of Building Sciences National Building Information Model Standard Industry Foundation Classes Information Delivery Manuals and International Framework for Dictionaries Based on and supporting Overview Building Information Models Insert your name and the name of the group you are presenting to on this slide. Identify your relationship and you are part of a national team putting together this standard which is being coordinated with the international community. Use the slides in this deck as the basis to tell the story you need to to the intended audience. Be picky and use as few slides as possible… Here are a couple recommendations - If you only have a couple of minutes use only slide #1, 2, 3 & 28 If you have up to 10 minutes then add in slides #11, 15, 16 & 18 If you have a minute presentation add in slides #7, 8, 10, 13, 19, If you have a minute presentation add in slides #9, 12, 20, 21, 22, 23, 24, 25, 26, 27 If you have more time use them all which adds in slides #4, 5, 6, 14 & 17 What makes this a national standard is the national ontologies that already exist that we must coordinate with such as Master format, Uniformat and other similar items unique to North America. This presentation is copyrighted by NIBS to ensure that one coordinated story is being told. NIBS National BIM Standard Project Committee November 2006 This presentation is a collaborative product of the NIBS NBIMS Project Committee.

2 BIM - What is it and why use it?
A BIM is a lifecycle information collection point for a facility A BIM allows for the creation of facility information relationships A BIM is focused on saving resources (dollars, time and materials) during each phase of the facility life cycle The more mature the model the more usable it is – but any collected data is better that how we do business today If you only have time for one slide, this should be it. These are the points you need to get across about BIM A BIM is a collection point for information about a facility – traditional approaches scatter the information about a facility in multiple products so you can’t get a clear picture of what is happening in the one facility you are looking at. Once the above occurs then you can form relationships wit the information about the facility this then yields analysis that could not be previously perfomred The goal of all this is savings pure and simple and the savings are significant, not as much in the design and construction as later in the life of the facility when you need information that was gathered during design and construction.

3 Building Information Model Definition
National BIM Standard Definition of BIM – buildingSMART 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 process to support and reflect the roles of that stakeholder. The BIM is a shared digital representation founded on open standards for interoperability. The National BIM Standard is part of the global buildingSMART Information Delivery Manual Initiative. This is the agreed to “standard” definition for a BIM. Key points are that it is digital so a machine can read and analyze it. It includes the entire life-cycle from inception onward It supports collaboration It is shared information and supports interoperability It is an open standard and free It is part of the overall buildingSMART initiative

8 What is Building Information Modeling [BIM]?
2D Lines and Text Building Is a Verb 3D Polygons BIM Virtual Construction 3D Visual Coordinated dataset Interoperable Lifecycle Knowledge Readily Exchanged Real Objects A BIM provides the ability to see and analyze the facility in near real life fidelity The advantage is having the electronic model which can be mathematically analyzed for compliance with codes This allows the elimination of conflicts which would turn in to change orders It also provides information to the owner for operations and sustainment.

9 How Does BIM Work? For Example… Accurate steel members
Building Is a Verb Accurate steel members - Size, weight, performance, cost. Accurate connections Accurate 3D position Simulation of - Installation process & equipment requirements - lighting - structural performance - etc. Overlap with other 3D elements to identify collisions. - Mech, elec, plbg, - Walls, ceilings, FF&E - Access for maint. & repair Courtesy: Kling Lifecycle Knowledge Readily Exchanged Real Objects Lifelike Properties During the design, shop drawing, fabrication and construction phases nearly all needed information is developed for a facility, unfortunately it currently typically just not captured and stored for future use. If you also capture information from the ordering and invoicing process you will have a very accurate model not only for use during construction but also for its entire lifecycle.

11 How Does BIM Work? All Stakeholders Participate
Legal Data Geospatial Data Financial Data Building Is a Verb Lifecycle Knowledge Readily Exchanged Designer Data Real Objects Lifelike Properties Ongoing Uses BIM Specifier Data Stakeholders all work on their own piece of the project, in their own applications, to accomplish their own deliverables. However, deliverables are changing to streamline the process and deliverables include information. (Following speakers will focus on how this works for Design and Construction phases.) Stakeholders in the building lifecycle process all contribute to the BIM. Each receives and creates value through their participation. The BIM is not typically one big database. More likely it is a number of databases with common key information and data standards. Many uses for many purposes: Design visualization, Reduction of Errors, Collision Detection, Quantity Take Off, 4D Constructability, 5D Cost Estimating, Asset/Equipment Inventory, Facility Operations, Space assignment, Maint/Repair, Emergency response, Many others… Owner / Occupier Data Sustainers Data Environmentalist Data Courtesy of NIBS National Building Information Modeling Standards Committee

12 Influence vs Cost Curve
Cost of Changes Virtual Building Design Proposed Entry Ability to Change Typical ‘Value’ Engineering ! Effort BIM can also help move the VE process forward in the process. It is far easier and cheaper to change an electron than it is to use a jack hammer to remove a wall. Strategy Design Construction Operation 25% 75% Lifecycle cost

13 Information Exchange Losses
Management support information should be: Collected continuously throughout facility life-cycle (created once) Managed uniformly in standard framework Securely available 24x7 Information Value Time Value of Improvements To-Be Minimized data loss Maximized information value As-Is Continuous data loss Value of information reduced This cost model shows the current (as-is) conditions with loss of information between each stage of construction due ot lack of interoperability. The next build shows the potential curve if information is retained between phases. The are between the curves shows the savings – estimated by NIST at $15.8B annually Planning Construction Design Operation

14 Notional BIM Project Savings Curve
This is a draft – a team is working to put actual numbers to these notional curves Conception Stage Project Delivery Selection Stage Design Stage Construction Documents Stage Procurement Stage Execution Stage Utilization Stage Closure Stage Optimized approach with virtual modeling and analysis with reduced change orders & delivery time and lower operating and sustainment costs Typical approach failing to do routine maintenance and having to replace items earlier and more often Typical design/build approach with required maintenance The savings we are currently experiencing with faster delivery and fewer change orders This model is not to scale and is under revision, however gives a more life-cycle oriented view of the outcome of implementing BIM than I have seen This is most effective viewed as a slide show using the builds – The gold curve represents the typical process we should now encounter – costs ramp up during planning and development and construction and then drop off during operations and sustainment slowly increasing as the facility ages The red curve represents what happen currently more often as maintenance and sustainment costs are deferred thus causing replacement costs to mount later in the life of the facility The blue cure represents the implementation of BIM and virtually building a facility and analyzing its performance prior to construction. Costs ramp up faster but construction, operations and sustainment costs are lower because energy usage is optimized and more sustainable materials are used. The first green savings identified are those savings that come from faster and lower cost delivery created by reducing the number of change orders and RFI’s. These are the savings we are currently seeing from the implementation of BIM in design and construction. However the significant savings are going to come when we start holding onto and sharing information gathered during various phases of the facilities life-cycle and not re-gathering information for each facility related activity. We have challenged the academic community and others to help validate and make this curve more accurate.

15 Typical BIM Benefits Better understanding of design concepts – shared understanding of issues More focus on value-added tasks Faster cycle times Reduced errors and omissions Less waste: rework, materials, time Fewer translation errors and losses Increased site safety Better estimates – cost and time Building Is a Verb Lifecycle Knowledge Readily Exchanged Real Objects Lifelike Properties Ongoing Uses Based on the information presented thus far we see that BIMs provide the benefits listed here VALUE

16 Who Benefits From BIM Implementation
Facility Information Views Owners Planners Realtors Appraisers Mortgage Bankers Designers Engineers Cost & Quantity Estimators Specifiers Contracts & Lawyers Construction Contractors Sub-Contractors Fabricators Code Officials Facility Managers Maintenance & Sustainment Renovation & Restoration Disposal & Recycling Scoping, Testing, Simulation Safety & Occupational Health Environmental & NEPA Plant Operations Energy, LEED Space & Security Network Managers CIO’s Risk Management Occupant Support First Responders Graphisoft BIM All these players should be able to receive information from a BIM. All are involved and have their own views of a facility that should be able to be satisfied by the BIM. Currently they typically all collect essentially the same information.

17 Facility Data That Could Be Included in BIM
Planning scenarios and site information Architectural program Floor plans Space functions Classified areas, vaults etc. Area calculations Volume calculations Engineering calculations Specifications Contract documents Legal description Change orders Supporting documentation for litigation Shop drawings Procurement documents Progress photographs Alarm diagrams Warranty data Invoices Purchase requests Cost Estimates Organizational occupants Personnel lists Seating plans Handicap designation Network diagrams Hazardous materials Operating manuals Maintenance records Inspection records Electronic 3D model Simulations Continuation of operations plans Disaster Recovery Plans Contingency plans Furniture inventory The listed information could be included in the BIM of a facility to be re-used by others. The problem today is that people do not collect information for others later in the life-cycle. If we do not solve this problem the natural event that will occur is that the facility management firms will end up controlling the process given the current mind set of planners, designers and contractors. There is just too much money to be saved that BIM will not happen.

18 Hierarchical Information Relationships
IAI-IFC Usage Space Natural Asset Linear Structure Structure Building Facility / Built Theatre / World Sub-Systems System Level Site Real Property Asset Country State / Province County Installation / Region Node Segment Room Water / Sea Land / Parcel Underground Air / Space Geospatial Information (GIS) Overlay Building information (Building Information Models) Components City This diagram identifies how information is rolled up from the facility level up to the world view. It is a joint effort from many in the industry including the Federal Real Property Council and OSCRE. It shows how information inside a facility links into the geospatial world.

19 Reports or Extracted Data from BIM (examples from all classifications)
Hierarchical Building Information Relationships Attributes Systems represent the physical entities of the building. Systems use NA classifications such as Omni-Class and Uniformat and are transported/exchanged via IFCs BUILDING Or Structure Metrics IFC objects, relationships, space SYSTEMS –Ex. Structural, MEP, Flooring, Ceiling, Exterior, Walls Attributes Space is physical in nature, but can be unbounded (have no or cross physical boundaries) but it will always be tied to the physical structure or systems in some way Attributes Metrics Sub-Systems (part of systems) Components Metrics Overlays are more abstract data - organizational, operational, functional, financial, non-fixed assets, resources, personnel, etc. that is data tied to the Systems and Space SPACE-Vertical Horizontal, Empty Example SUI,CI Metrics Level (Stories) Room Attributes Standards Void Vertical Metrics Reports or Extracted Data from BIM (examples from all classifications) Attributes From the previous slide we go down into the next level which is at the heart of the BIM. Systems are items such as structural systems, mechanical systems, closure systems and the like. Space is the room as s well as the void and adds up to the total footprint. Overlays are polygons that lay over the space and systems that could be heating zones, fire protection zones, organizations, financial cost centers, etc. It is also important to note that floor plans are only reports off the model. OVERLAYS – Typically associated with building hierarchy elements.

20 Information Exchanges
Programmatic and Project Requirements or Constraints (LEED Silver requested by owner) Normative standards by which data is collected or managed (Such as the IBC, NCS, IFC’s and OmniClass™) The reason for the information exchange (i.e. Desire to buy doors) Report on Door Objects Control BIM Output Input The product of the information exchange (i.e. The quantity and specification data used to purchase and deliver doors. The information exchange BIM In looking at the details of an information exchanges we see the identification of what information is needed to accomplish a task and what the intended product is. We also see that some of the information developed during that process is stored in the BIM to be able to be re-used by a subsequent information exchange. Existing information already in the BIM is used as input and information that is gleaned from the exchange is also stored in the model (i.e. Attributes about the doors purchased, size, material, cost, instructions, fire rating, etc.) NCS, IFC’s, OmniClass More information is added to the building information model in its appropriate spatially related location

21 Use of Information Exchanges to Support BIM
Requirement & Goal Standardize on information needed for specific tasks within the building lifecycle Development based upon open data standards used by all Provides requirements to software companies North America data standards CSI, OMNICLASS, Uniformat International Bldg Code CIS/2 and other authorities Here is another view of the benefits of coordinated information exchanges. This capability was demonstrated recently at the buildingSMART Industry Day at the National Academy of Sciences on November 1, 2006. The following companies demonstrated their products all working off the same Norwegian project – HITOS. The following groups were all working on the same IFC model on stage at the same time. - BIM is here Graphisoft - information markers, 3D pdf Bentley - import model - export to Google earth 3D pdf, EliteCAD - Netherlands, new system - simple. The Sketch Up of BIM, just now supporting IFC CRC - Australia Code Checking - did a ground plane related area calculation that is required in Australia Solibri - Accessibility checking, door sizes for routing, toilet wheelchair circles. Navis Works Jetstream - powerful viewer, bring together files of any format. DDS Viewer - free - not only geometry, but information, even edit model by adding information and save updated model. IFD (dictionary) - go to library, chose language, find the item to add something. CSI is working on  US  language version. Design into procurement. Item chosen goes into IFC model. Octaga - high quality visualization model viewer. Change out materials on the fly, what ifs... Not quite Max for IFC but that direction. cRofus - build room data sheet, export raw geometry into CAD, or work in CAD - import BIM IFC into cRofus. Model check between plan / model program - actual Grunland - MEP - Imported BIM, simulation and analysis for MEP, both envelope and inside loads, test things like add window shades / rerun. Also energy performance - can export this back to BIM. Tekla - BIM Structure - analysis to IFC DDS - IFC MEP Software (no details) Electrical safety - circuit diagrams, panels, etc. Interesting because there is no 3D stuff, just diagrams. Fix it and send it back into IFC model. CRC - Australia - Environmental impact model, (also earlier code check demo) change a finish, check, etc. Gemini Terrain - zoning, mapping, GIS / IFC link buildable volume display - Google earth - byggsok permit application to check zoning and EDM model server to share and accessibility check Specification and costing - views broken down by Uniformat or whatever. RAMBygg - Denmark - IFC based FM system focus on grouping building systems in light of maintenance. Digital Alchemy - IFC view in Visio. Not yet released, but important that this is Microsoft / IFC connection - could be useful in many ways. Oracle - collaborative BIM platform, built a web viewer with markups EPM ModelServer - check in - checkout through IDM or ownership / discipline, etc. central hub for various applications Onuma planning system - web based, bubble diagrams, links to excel or whatever, round and round.

22 Case Study – Letterman Digital Arts Center
“Despite numerous design layout changes that were required by Lucas Film Ltd. due to company restructuring, the LDAC project was completed on time and below the estimated budget….over two hundred design and construction conflicts were identified, most of which were corrected before construction, resulting in an estimated savings of over $10 million on this $350 million project.” Key point in this case study was that they had a documented $10M savings on a $350M facility just from eliminating potential change orders We now have hundreds of case studies demonstrating significant savings Most of the savings currently identified come from the elimination of conflicts and the resulting change orders In the future even more savings will come from having detailed information about facilities during operations and sustainment Courtesy of AECbytes "Building the Future" Article (September 30, 2006) Building Owners Driving BIM: The "Letterman Digital Arts Center" StoryMieczyslaw (Mitch) Boryslawski, Associate AIA Founder, View By View, Inc.

24 USCG Integrated BIM/Mission Support Approach
Identifying Mission Requirements… …Using BIM, Web Services and IFC’s to Support Decisions and Cost Effectively Plan for the Future… …To Provide the Right Products to their Customers based on Mission Requirements This case study from the Coast Guard shows how with BIM you can show how facilities directly support a mission.

25 Philosophical change in approach
Planned information relationships Current Lack of Interoperability A B 2 3 Building A Building B Building C 1 3 1 2 4 4 1 3 2 Subject 1 Subject 2 Subject 3 Subject 4 C 4 Start with a “BIM Blob” Add shape Add additional information End up with a mature BIM or obtain a complete BIM with new construction All it takes is a basic cultural/philosophical change. Currently we have multiple applications all working on the same facility, but they are disconnected so sharing of information cannot occur. The shift in thinking is to collect data in a structured way for each facility, then analysis and reporting can still be done across multiple facilities, but it more can be accomplished in the same facility without re-gathering similar information. Once the structure is established then you can grow the BIM, starting with basic information which might not even have a graphic segment – a red BIM blob. As information is gathered then the blob takes shape and matures eventually to a complete BIM, if that is what is desired. It can also be matured only to a pre-determined level. Estimated or less accurate information could be inserted so that the facility could be included in analysis or reporting. Confidence levels can be attached o less accurate information. Since the information is structured, even if you don’t have a complete model you can still report based on the information you do have. Information is available about a subject across all facilities but not about all subjects across all facilities

26 Emerging buildingSMART-NA Initiative
Draft Role A Strategy for Improving Facilities The buildingSMART Alliance will: Act as a focal point for improving facilities efficiency Establish consortia arrangements for conducting research, Conduct forums and workshops, Manage research and research-related projects, Disseminate information, Review work performed by others. Develop and recommend standards, guidelines and certification programs; Stimulate innovation in the industry Promote increased understanding and communications BIM is the result of a higher level of coordination through the facility industry emerging under the title of buildingSMART. This coordination is required to ensure that the same concepts are being promoted in all facets of the facility industry.
