BIM from the Construction Manager General Contractor Viewpoint

BIM from the Construction Manager General Contractor Viewpoint Barnhart, Inc. a Heery International Company Sumeet Gadi Senior Vice President Randy La. Near BIM Manager ACCM Conference June 19 th – 20 th Newport Beach CA.

Barnhart, Inc. a Heery International Company n n n Founded in 1983, celebrating our 25 th year Headquartered in San Diego 6 Regional Offices throughout California 4 th Largest Educational Builder in the Nation Largest K-12 Educational Builder in the Nation A pioneer in use of new technologies for the construction industry

Why Barnhart implemented BIM n Strategic Considerations n n n We are committed to being a Leader in technology use in our industry We have historically been in the forefront of new technology adoption BIM is the wave of the future Increasing awareness and desire among Owners Tactical Considerations n n n Design Validation – Constructability Analysis – Interference Detection Construction Planning – Visualization Construction Coordination – Trade Collaboration

How Barnhart implemented BIM n Strategic Considerations Level of Corporate Commitment n Baby Steps Vs. Deep End of the Pool n Resources n n Tactical Considerations Project Selection n Decide Extent of Modeling n Define Deliverables n

How Barnhart implemented BIM n Strategic Decisions Full Corporate Commitment n Deep End of the Pool n In-house Core Competency with Out-sourced Augmentation n n Tactical Decisions Del Norte High School n Complete Architectural/Structural/Systems Model n Construction / As-built / Facilities Model n

Construction Management Real Life Applications Of BIM / VDC / IPD n n n BUILDING INFORMATION MODELING VIRTUAL DESIGN CONSTRUCTION INTEGRATED PROJECT DELIVERY BIM / VDC / IPD How does it provide Advantages and Benefits And What Challenges to Expect Project Examples n n Del Norte High School, Poway Unified School District Oceanside High - Performing Arts Center, Oceanside Unified School District BIM Topic n n Project scenarios Defining the BIM Process

BIM Current Real World Use CD’s, Drawings, Plans, Models, Projects & Workflows How are we utilizing BIM and what BIM tools are we using n n Constructability (clarification, interference detection, ) Scheduling Timeliner in Navisworks 4 D Quantity Takeoffs 5 D LEED Certified Projects Today’s Tools & Workflows n n n Revit Architectural, Structural, & MEP 2009 Navisworks Manage 2009 Auto. CAD MEP 2009 VE – Toolkit USGBC LEED Planned Future Tools and Possible Work. Flows n n n Autodesk 3 Ds Max Innovaya or Quantity Takeoff Integrated Project Delivery

Construction Challenge for Del Norte High School Production Studio Room A 150 n n Sloped Structure above Space No Section Cuts in Construction Documents How to fit everything into the space had been only conceptualized @ best Mechanical Return Air duct to adjoining space wouldn’t fit across the Supply air duct and between the Suspended ceiling and the pipe batten system. Architectural Elevation Architectural Floor Plan Mechanical Floor Plan

BIM Solutions for Del Norte High School Production Studio Room A 150 Coordination n n Suspended Gyp Board Ceiling Tight Space Requirements Pipe Batten Grid For Production Studio Original Design would not fit Interference Resolution n n Space Requirements verified by Model Placement reviewed with Field personnel Pipe Batten Hardware Rep able to visualize space and equipment in relation to structural Navisworks files created for full visualization and communication of the space New Routing and layout per collaborative BIM review effort

OHS Performing Arts Center n n n n Three disciplines Modeling the Project in Autodesk Revit Architectural, MEP & Struct. First BIM Project for all Three Architect Self taught in Revit MEP consultant had basic training Structural Consultant had basic training The Challenge BIM to CD’s Mechanical floor plan that clearly shows the ducts penetrating the Auditorium Floor Right ?

Overcoming Project Challenges and changing Industry Mindsets n BIM Model really does clearly showing the ducts penetrating the Auditorium Floor !

How Barnhart utilizes Navis. Works n The Views n Seeing is Believing n Graphical communication n Viewer for team members n Collision detection n Time Liner n Renderings n Presentation n Speed

BIM as a Project Approach Utilizing a BIM Workflow on a Project will Naturally bring about Collaboration n Responsibility n Accountability n With a BIM Workflow and BIM models the focus becomes project focused not CD focused and Drives an integrated Project Delivery Process Mutual Respect and Trust n Mutual Benefit and Reward n Early Involvement of Key Participants n Early Goal Definition n Intensified Planning n Open Communication n Appropriate Technology n Organization and Leadership n With a BIM model you can produce your CD’s from the BIM model and everything matches between the BIM Model and the CD set

BIM Advantages and Benefits Leveraging BIM for Coordination n Visualization n n Coordination Review n n Between Linked Files and Within Single File Project Review / Quality Control n n Monitor other Disciplines work (Grids/Levels/Walls/Floors/Columns) Interference Check n n Coordination and Design / Improved Workflow Project Managers Coordination Schedule Downstream Usability n Construction Industry – Data Shared for Phasing Coordination, Facilities Lifecycle Management

BIM Challenges and Obstacles Summary n n n Change (Human nature you know) Current Practices (Construction Project Delivery Systems) Interoperability (Between existing software platforms) Qualified People Legal Considerations Industry Understanding of just what BIM is and is not Industry Acceptance and application of these understandings Initial Cost to Change (hardware, software, training, implementation) Defined Deliverables Defined BIM Processes Defined BIM Project Roles

BIM Advantages and Benefits Summary n n n n Design Visualization Design Assistance & Constructability Review Site Planning & Site Utilization “ 4 D” Scheduling and Sequencing “ 5 D” Quantity Takeoffs / Cost Estimating Integration of Subcontractor and Supplier Data Systems Coordination Layout and Fieldwork Prefabrication Facilities Operation and Maintenance Project Delivery Methodology Time Savings Cost Savings Mitigated Risk
