Envelope Parametric Design

Chris O’Hara, Studio NYL

This presentation discusses how Studio NYL’s design process integrates BIM, parametric design, visualizations and integration with the analytical engines the company uses to achieve dynamic designs that both enhance the project’s architectural intent and finds cost savings faster than previously possible. Chris discusses these techniques using case studies of built projects and projects currently on the boards. Achieve better more efficient designs faster on some of the most challenging projects around the world both large and small.

Chris is a founding principal of Studio NYL, a Boulder, Colorado-based structural engineering and façade design firm known for its exemplary skills. Chris and the firm are known for their use of non-traditional materials and systems in unique ways which has them sought out by both Architects and Fabricators around the world. Studio NYL’s team excels at bridging the gap in the design of complex geometries in BIM platforms and their integration with analysis engines; and direct-to-fabrication projects.



Parametric Modeling for Preliminary Design

Mike Bolduc, Simpson Gumpertz & Heger

Early in the design process the structural design is traditionally limited to isolated bay studies and general lateral massing. With parametric modeling, we are hoping to break the typical early limitation on analysis to provide comparative feedback on the structural design models as the architectural model evolves. As structural engineers we can offer valid structural feedback in real time to evaluate and compare different architectural massing features. This early feedback will enable the design team to make more cost effective design decisions when they can provide value to the project costs and schedules.

Mike is a registered Professional Engineer in Massachusetts and a Senior Project Manager at Simpson Gumpertz & Heger Inc. in the Waltham office. He has over sixteen years of structural design experience and has been working in BIM for over a decade on a variety of projects, including healthcare design, commercial design, and precast concrete structures. He works to leverage the power of BIM for coordination, design efficiency and even developing fabrication ready models. He is a co-chair of the Council of American Structural Engineers-Structural Engineering Institute’s BIM committee and active member in the BIMForum.


Tolerances & The Intolerant World of Structural BIM Coordination

David Merrifield, Steelfab Texas

Tolerances are a critical concept in design and construction and a challenge in BIM where objects are normally represented in their theoretical final position. This session introduces the topic of tolerances with BIM, explores some common challenges, and discusses approaches to take on this fundamental topic.

Dave Merrifield has over 50 years of experience in fabrication, engineering, erection and project management of major projects across the United States and in several foreign countries. He joined Alpha Fabrication Services in 1995 as President which is now SteelFab Texas, an AISC Certified Steel Fabricator. He is a Board member of the Nation Institute of Detailing and chairman of the Quality Procedures and CD-BIM committees. He is President of the Texas Structural Steel Institute an AISC affiliate organization. An early member of the BIM Forum, David continues to serve on the LOD Core group as co-chair structures and is a member of the BIMXP task force. As a lecturer and presenter, many of his presentations can viewed at events such as NASCC, Autodesk University, BIMForum and monthly CD-BIM Webinars. His recent article “Quality Procedures in Detailing Offices” was just published in Modern Steel Construction. David was just named NISD “Man of the Year” for 2017 at the NISD annual meeting.


Delivering the GigaFactory in Tesla Time Using HD BIM

Greg Luth, Gregory P. Luth & Associates, Inc.

We believe that the best design is one in which all the important decisions regarding materials, means, methods, sequences, and schedules are made during the design when all the impacts and costs project-wide can be considered and when the design itself can be altered to optimize schedule, quality, cost and supply chain issues.This presentation provides a case study overview of our 11-year odyssey from a CAD to an HD BIM workflow, where we take our design from concept through as-built, including shop drawings production along the way, using a single cloud-based model that is shared and accessible to all members of the design-construct-own team.

Greg Luth is a former US Marine who received his BS degree from the University of Alaska, Fairbanks, and went on to get his MS, Engineer, and Ph.D degrees at Stanford. He has been a consulting structural engineer for 41 years and has his own practice in Santa Clara, California. His practice focuses on a wide variety of commercial projects for which he delivers performance based designs utilizing the HD BIM process.


The Profit: SE Business and BIM Wisdom (Learned the Hard Way)

Will Ikerd, IKERD Consulting

This session teaches how to increase profits while lowering risks. It presents information on thinking beyond being a sub-consultant and how you can bring true value by delivering the structure as early as possible. One focus of the session is on understanding the critical path to process. It includes lean processes for the structural engineering office with BIM using the BIMForum Level of Development of Specification as a tool to manage risk, define scope, and secure profits. The importance of understanding BIM coordination and laser scanning is covered as tools for successful project outcomes. This session provides an update of current trends and an in-depth review of the new BIMForum LOD Specification as it relates to structure. The session also discusses the standard of care and what is currently considered industry standard, and also includes discussions on BIM Execution Plans and how they should include reference to the BIMForum LOD Specification.

Will is principal at IKERD Consulting, an internationally recognized consulting group in buildings, civil, and industrial construction markets specializing in using Building Information Modeling (BIM)-enabled Virtual Design and Construction (VDC). He serves as an expert consultant in design and construction cases involving BIM and VDC processes. He is currently on the board of directors of the national BIM Forum, and was past chair of the Structural Engineering Institute’s national BIM Committee. He has won the Best Speaker award twice from the International Structures conference, and he was named Structural Engineering magazine’s “Top 10 Leaders in Structural Engineering,” Glass Magazine’s “Top 30 under 40,” and Building Design & Construction magazine’s “Top 40 Under 40.” He has served as PCI’s BIM consultant in that industry’s innovation initiatives


Building a Virtual Bridge from Design to Construction

David Aucoin & Matt Sweeney, PES Structural Engineers, Inc.

Structural engineers possess a wealth of knowledge beyond that which can be conveyed in traditional drawings and design intent models. By embracing the BIM process and forging strong relationships with other members of the project team, it has been possible to contribute more value and earn more business. In this presentation, we walk through several brief case studies in which we were contracted to model structure beyond standard design documentation to identify constructability issues before they arise in the field. Our presentation will culminate in a roundtable discussion to help the audience identify opportunities for delivering more value to clients by applying some of the lessons shared throughout the day.

David is a Senior Associate in the New England office of PES Structural Engineers. He has over 12 years of experience in the structural design of steel, concrete, masonry and wood framing systems in a wide variety of markets including hospitality, industrial, multi-family housing, retail, healthcare and religious facilities. As a Studio Director, he serves as the primary client contact for the New England office and oversees a team of project managers and engineers.
