BIM from Concept to Completion Presented by: Darren R. Hartman, P.E., LEED AP (Vice President) Thornton Tomasetti November 16, 2010

Who We Are

Our Mission To collaborate with clients to create the best building solutions for the entire building lifespan. Our Values  Collaboration: Listening is not a spectator sport. We seek out ideas and goals and build upon them.  Creativity: We are driven by original ideas.  Commitment to excellence: Attention to the details, while keeping our eye on the big picture.  Caring: Doing the right thing for our clients, our colleagues and our communities.  Our Vision Always reinvent how buildings are imagined - and built. Our Guiding Principles

Where We Work  12 U.S. Offices, Abu Dhabi, Dubai, London, Moscow, Shanghai, Hong Kong

Our Market Sectors Aviation & Transportation Commercial Cultural & Institutional Education Healthcare Hospitality & Gaming Parking Residential Special Structures Sports & Entertainment Our Practice Areas Building Structure Building Skin Building Performance

The BIM Concept

The Current BIM Concept  Who’s Involved?  Architect  Engineer  Mechanical  What’s Involved?  Clash Detection  3-Dimensional Modeling  Coordination of Mechanical Systems It is a Linear Process

Our BIM Concept BIM is more than just clash checking and 3D modeling. This is a process that’s maintained throughout the entire project. By doing more of the process, we establish expertise for each of the disciplines. We can do the work ourselves or we can coordinate the work more effectively.

Construction Support Services Integrated Modeling Services

Detailing During Design Using Tekla  Phase I (Mill Order Model)  Phase II (Connected Model)  Phase III (Drawing Extraction)  Precast and Cast-in-Place Construction Support Services Integrated Modeling Services

Steel Detailing During Design Using Tekla Structures Integrated Modeling Services

 Main framing members in Tekla  Digital model used directly by contractors –Advanced Bill of Materials (ABM) –More accurate material take off for bid –Reduce overall schedule Phase I – “Mill Order Model”

Integrated Modeling Services Phase I – Design Drawings

Integrated Modeling Services  Selected connections completely detailed in Tekla  Lateral system major details  Long-span major details  Others are project-specific  Connection designs in 3D model  Fabrication starts sooner  Design intent clear  Project complexity clear  Owner gets digital 3D model file  Ready for steel fabricator detailers to create shop drawings Phase II – “Connected Model”

Integrated Modeling Services Phase II – Design Drawings

Integrated Modeling Services  Drawing Extraction  Often delegated to fabricator  Then out-sourced -- Low cost labor  Thornton Tomasetti can/should self-perform on select projects Phase III – “Drawing Extraction”  Performing here can speed schedule on some projects  Shop drawings complete at Award  CNC Downloads readily available  Speeds Shop Drawing Review

Phase III – Drawing Extraction Integrated Modeling Services

As Part of Design Projects (Add service or basic fee)  Partial reinforcement detail of congested areas  Deliver detailed reinforcing details as design deliverables  Required on several current international projects Stand Alone Service to Contractors  Design and detail precast Precast and Concrete Modeling

Integrated Modeling Services Precast and Concrete Modeling  Model different structural elements  Enhances clash detection  Better trade coordination  Full profile element models  See clearances and connections  Single model: Steel, concrete, wood  Coordinating for much more intuitive design  Becomes basis for RFID control

 The use of Tekla-driven Building Information Modeling (BIM) allows for enhanced design and visualization of complex structural conditions  Model (or components of) can be delivered to reinforcement subs that embrace technology Integrated Modeling Services Precast and Concrete Modeling

The Production Model The BIM Model

The Production Model  One model design process  One model to carry through the detailing  One location for all of the information  One model to maintain and coordinate

One Model Design Process  One model is used to house the geometry as a master model  Pieces of this model are used for analysis  Analysis results are incorporated into the master model  Trades are coordinated with exports of the master model

One Location for the Information  All of the history and the data about a member is in the model  Size, location, end loads, camber, RFI and anything about a specific member is located in the model  The data is maintained and expanded throughout the process

One Model to Maintain and Coordinate  No more making sure the models match  This reduces hours of review and copy check time  Exports from one model to other trades ensures that all trades get up to date information

Case Study: Washington Nationals Park  Design/Build (IPD Approach)  Change in Ownership  3 Months – Start to Mill Order  Architect Early Sign-off  26 Months – Concept to Handover  Result: Team Wins!  Nationals still lose…
