Contract Deliverables (2D, 3D, hybrid)
Typical workflow for information exchange to builder
What role is IFC or other digital formats playing
How would the ACI BIM exchanges affect the current workflow?
What or who are the catalysts for change?
Where do we think cast‐in‐place concrete will be in 5, 10, 15 years?

Concrete BIM Software (By Vendor)
• Modeling in 2D and 3D
• Reinforcement design and layout in 2D and 3D
• Detailing for construction
Data Interoperability (Panel Discussion)
• Native (API) or Neutral (IFC) – Could your market survive with just one or need both?
• Today, where is most of your IFC development/resources? (structural or non‐structural)
• In your opinion, how do you think the ACI 131 work, including the IFC support by GA Tech, will impact the overall industry acceptance of BIM for concrete?
• In your opinion, is this work proceeding on “pace” or “lagging” relative to the Industry? And, if lagging, how could it be accelerated?

ACI 131 ‐ Building Information Modeling of Concrete Structures
Committee Mission: Develop and report information on the application of building information modeling to concrete structures.
Goals: 1) Develop/promote data exchange standards for concrete
2) Develop new work processes for concrete BIM projects
3) Present case studies of successes on concrete BIM projects
4) Develop concrete BIM short course(s)
5) Understand what gaps currently exist in software and workflows
6) Develop standard test models for BIM software
7) Understand legal implications of BIM projects.

ACI 131 ‐ Building Information Modeling of Concrete Structures
Current Work (Next Publication): • IFC Model View Definitions (MVDs) for 3 of the 20 IDM Exchanges
• Deemed “high value” for increasing overall efficiency
• EM‐6: Structural Design (Intent) Model (i.e. Plans & Specs)
• EM‐15: Reinforcement Placement Model (i.e. Rebar Shops)
• EM‐20: Construction Reference Model (i.e. Almost All)
• These MVDs are another big first “hurdle” critical to overall success

EM‐6: Structural Design Model: defines structural intent, specifying concrete profiles, steel reinforcing in members, lap standards, spacing requirements, tendon requirements, major joints and embeds
EM‐15 Reinforcement Placement Model: full detailed rebar layout with ties, laps, from detailer to fabricator; tagged with placement sequence
EM‐20: Construction Reference Model: detailed placement model, with pour objects, finishes and formwork; for final coordination with all other systems.

ACI 131 ‐ Building Information Modeling of Concrete Structures
Status (now through September 2015): • Data Sets for EM‐6, EM‐15, and EM‐20 Model View Definitions (MVDs) • EM‐6 Structural Design (Intent) Model • 90% Complete
• Requires developing some new parameterized objects not in IFC
• EM‐15 Reinforcement Placement Model
• 95% Complete, ready for first review
• EM‐20 Construction Reference Model
• 85% Complete, some further refinement necessary BIM Industry Strategic Meeting

Future Work (now through 2016?): • Documentation/Implementation Phase ‐ EM‐6, EM‐15, and EM‐20 MVDs • Committee
• Fall Convention (Denver) ‐ Draft of MVD data sets/Test Ballot
• Begin work on Publication including TAC review
• GA Tech with Software Vendors (IFC Support)
• Preliminary implementation and testing (GA Tech)
• Implement and debug new rule sets (GA Tech)
• Work with software companies in implementation and testing
• EM‐15 released first, available for use, followed by EM‐20, with EM‐6 released last.

ACI 131 ‐ Building Information Modeling of Concrete Structures
Collaboration with GA Tech: • Long history of IFC expertise (PCI, AISC, ACI)
• MVDs require IFC expertise that users (even software vendors) don’t have
• Expertise in Testing and Validation of MVD’s (neutral party)

ACI 131 ‐ Building Information Modeling of Concrete Structures
Summary: • IDM (Information Delivery Manual) ACI 131.1R‐14
• Comprehensive “Road Map” to Document our Industry for BIM
• MVDs (Model View Definitions) ACI 131.X?
• EM‐6, 15, 20 Cover Major Segments of a Digital (BIM) Workflow
• If adopted by Vendors/Users, may formalize a BIM Transition in Industry
• We believe we are moving forward in transforming BIM for the Concrete Industry
• But, as a Technical Committee, how far should we be going (alone)?
• We need your support.
