Setting Owners Expectations & Defining Project Scopes with the Sample LOD Model

David Merrifield, Steelfab Texas

Project owners in BIM are facing an emerging challenge of how they set expectations and defining project scope in the area of Level of Development. The BIMForum Level Of Development has gone a long way in providing a dictionary for object definitions in a BIM project. This sample model goes to the next step by providing a training example a sample “Story” of LOD using the BIMForum LOD “dictionary”. This session provides a LOD sample model as part of the CD-BIM curriculum that illustrates the progression of a Medical Office Building in a Design-Bid-Build scenario at 6 key project milestones of Schematic Design (SD), Design Development (DD), 50% Construction Document (CD), 90% CD, Permit Documents – 100% CDs and Issued For Construction (IFC) Documents. It is a clear, well documented example that any owner can reference as an example a implementation of the BIMForum’s LOD on a project realistic project. The sample LOD model will highlight structural development of element form LOD 100 through 300.

This presentation shows how the model provides a reference for the latest 2016 Level of Development Specification, using a three-story medical office building. Input is incorporated from a fabricator and architect for guidance as the structural model is developed through four key stages.



Building Envelope Enclosures That Work, What Owners Want!

Will Ikerd, IKERD Consulting

Building Envelope Enclosures are one of the largest risks monetarily that an owner faces with their buildings. This issue is also one of the number one reasons contractors are called back to projects, and the leading reason of construction lawsuits. Designers are at the point of the spear of this issue as their designs flow into construction. Coordinating designer’s enclosure details is an ever-growing challenge for them as building systems become increasingly more complicated with materials and integrating lighting and mechanical systems with the enclosures performance. The challenge is further highlighted when we consider that physical mockups of enclosures seldom work at their first test.

This session provides a detailed review of the use of BIM and Virtual Design and construction (VDC) in addressing the BE challenges. It highlights the use of the BIMForum LOD specification, and how it is used with the design and construction teams. It outlines best practices for Building Enclosure Review Meetings with BIM. It discusses VDC through the entire process of design, construction, and enclosure maintenance. The audience walks away with practical and usual steps they can take on their projects to provide building owners enclosures that work with best practices with virtual mock ups and BIM enclosure process.

Mid-rise Wood Frame Coordination

Steve Bumbalough, ITW Building Components Group

Companies are using BIM on wood frame mid-rise projects. They design, collaborate on, prefabricate and install foundations and wood framing for multifamily projects with exceptional quality. Part of the process includes a comprehensive architectural review and model, as well as a complete structural model. Once the structural model has been developed, it is clashed with mechanical, plumbing and other BIM content to fully coordinate the structure.

LOD continues to be a main point of focus as BIM savvy owners and builders advance requirements contractually for BIM content. For example: provide a model containing elements at LOD 200 for preliminary clash and coordination, whereas the elements are enhanced to a LOD 350 at the construction stage when deliverables are generated for field use.

Successfully using BIM on numerous mid-rise wood framed projects continues to provide enhanced clarity, from concept through construction for all project stakeholders. As technology and collaboration tools are further developed, the use of BIM will continue to grow. This session shows how educated owners and developers will be able to select BIM capable dynamic teams that can effectively design and build midrise wood frame projects with enhanced schedules and elevated levels of quality with less risk.

Learning Objectives:
– How BIM can be used to add value and eliminate construction issues that typically create problems in wood framed mid-rise construction.
– How BIM is being used today specifically for mid-rise wood frame construction, allowing prefabrication and offsite construction techniques.
– Why owners and developers should require BIM criteria on mid-rise wood framed projects while addressing contractual requirements and the LOD Specification.
– How BIM is used throughout the design and construction process for wood frame mid-rise projects.
– How the LOD specification should be addressed in mid-rise wood frame RFP’s.

Based in the DFW area of Texas, Steve Bumbalough is a Product Manager for the development of software solutions for Light Frame Structural Detailing on the Autodesk Revit platform. He brings almost 30 years of experience with fabricated wood structures to his position. His background includes not only design and engineering, but manufacturing and installation of all types of wood structures including custom and production single family and multifamily and podium construction. Having operated multiple fabrication facilities and providing turnkey installation with his own framing crews, Steve brings a pragmatic approach to off-site prefabrication of timber structures.


Validating Coordination: Present and Future

Kelly Cone, ClearEdge3D

Virtual coordination is only as good as the field installation that follows it. With 3D Coordination now a commonplace on most large vertical construction projects, the industry as a whole is bumping into a seldom talked about challenge in construction – quality assurance. We spend tens or even hundreds of thousands of dollars in man-hours developing detailed coordination models to enable pre-fabrication, reduce our schedule risks, and hopefully offer a higher level of quality to our clients. But, how much time do we spend validating that what gets installed actually matches what we coordinated? Why does it matter? How can we efficiently check installation of work and conformance to tolerances? Can laser scanning or other reality capture tools help? To explore this topic we show two quick case studies of projects with in-depth coordination efforts that required field validation and the interesting results that were discovered.
