SEMINARS AND SPEAKERS
Progressive Wood Construction: The Evolution from Low-Rise to Tall Wood
Dean Lewis, PE, SE, DCI Engineers
As a structural building material, wood has been a staple in the US for hundreds of years. However, recent decades have seen a dramatic change in the type and scale of wood projects. As codes have evolved due to recognition of the fire and life safety, structural, and resilient capabilities of wood-construction, new doors have opened that allow larger and taller wood buildings. Concurrently, advances in the technology behind the production of wood products and components have led to the introduction and increased use of off-site construction and mass timber. This opening plenary will take attendees through the progression of wood construction—from light-frame low-rise, to mid-rise, to mass timber and tall wood. With an emphasis on design topics and code provisions applicable to all of these building scales, this session will set the stage for the in-depth technical talks taking place throughout the day.
Dean Lewis is a licensed structural and civil engineer and Associate at DCI Engineers. He is a crucial member of DCI’s San Francisco office, which, within a 5-year timespan, has amassed a portfolio of more than 5,000 units of multi-family housing at various stages of design and construction. Dean’s expertise spans a wide variety of prefabrication and modular construction methods. His earliest work involved prefabricated steel projects in Africa, Indonesia and South America. Later, in Seattle, his experience included both light wood-frame projects and the Bullitt Center—the largest modern mass timber project in the US (at the time) and the first office building to achieve Living Building Certification. Since calling the Bay Area home, Dean continues to emphasize prefabrication and modular approaches utilizing materials such as mass timber, and integrate these techniques into office, residential, commercial and industrial projects.

A New Path Forward for Tall Wood Construction: Code Provisions and Design Steps
John “Buddy” Showalter, PE, American Wood Council and Scott Breneman, PhD, PE, SE, WoodWorks
We are at an exciting confluence in timber construction. The need for sustainable, urban construction has never been higher. Concurrently, mass timber products such as CLT have opened the door to many new opportunities for construction, one of which is tall wood. In January 2019, the International Code Council (ICC) approved a set of proposals to allow tall wood buildings of up to 18 stories as part of the 2021 International Building Code (IBC). This presentation will introduce the new tall wood code provisions in depth. Starting with a review of the technical research and testing that supported their adoption, it will then take a detailed look at the new code provisions and methods of addressing the new requirements. Topics will include fire-resistance ratings and allowances for exposed timber, penetrations, sprinklers, connections, exterior walls and much more. Designers can expect to take away the knowledge they need to start exploring tall wood designs on their projects.

Knock on Wood: Acoustical Solutions in Mass Timber Structures
Denis Blount, CTS-D, ARUP
The use of mass timber in multi-family and commercial buildings presents a complex set of acoustic challenges. While laboratory measurements of the impact and airborne sound isolation of traditional building assemblies, such as concrete, steel, and light wood-frame, are widely available, fewer resources exist that quantify the acoustic performance of mass timber assemblies, including CLT and nail-laminated timber (NLT) systems. Furthermore, acoustical professionals are not typically retained for mass timber projects, placing the acoustic responsibilities on the design team. This presentation will review common mass timber assemblies and acoustical rules of thumb for architects and designers. Topics will include detailing strategies, options for eliminating flanking paths, and best-practices for achieving good acoustic performance in mass timber buildings.

Structural Mass Timber Design: The Engineer’s Role in Optimization
Gregory R. Kingsley, PhD, PE, KL&A Structural Engineers and Builders
Achieving the highest level of cost efficiency possible with mass timber requires an understanding of both material properties and manufacturer capabilities. When it comes to laying out a structural grid, the square peg/round hole analogy is pertinent. Trying to force a mass timber solution on a grid laid out for steel or concrete can result in member size inefficiencies and the inability to leverage manufacturer capabilities. Knowing how to best lay out the grid—without sacrificing space functionality—allows the designer to optimize member sizes, but cost efficiency for a mass timber building goes beyond column spacing. This presentation will examine the structural engineer’s role in optimizing a mass timber structural layout by taking a systems vs. product approach. Topics will include known parameters for mass timber design, design challenges, connections, grid spacings, and lessons learned from the structural design of Colorado mass timber projects.

Urban Solutions for a Global Carbon Challenge: Timber City
Alan Organschi, Gray Organschi Architecture
By 2050, sixty six percent of the world’s population is expected to be living in cities. Accordingly, the need for more construction in urban areas is expected to rise. This presentation explores how new uses of wood and new techniques of carbon accounting for individual projects might be applied more broadly to address exploding demand for buildings and infrastructure. It will start by looking at new uses of mass timber through the lens of the recently completed science and art building at Common Ground High School in New Haven, Connecticut, one of the first educational buildings in the US to use CLT in its primary structure. It will then review the efforts of Timber City, an ongoing research project that explores the environmental efficacy and the industrial, structural, and architectural potential of urban mass timber construction technologies.

Code-Compliant Fire-Resistance Design for Wood Construction
John “Buddy” Showalter, PE, American Wood Council
Determining the proper code application for fire-resistant wood-frame assemblies and exposed wood structural members can be challenging and is often further complicated with increases in a project’s size and scale. In a building environment where the ability to maximize height and area is key to cost effectiveness, designers must understand the gamut of fire protection considerations applicable to wood structures. This presentation will include code requirements, compliance options and nuances related to assembly selection for required fire resistance-rated floors/ceilings and roofs/ceilings, interior and exterior walls, fire barriers, fire partitions, and fire walls. Topics will also include distinctions between fire-resistive elements for separation vs. type of construction.

CLT in the US: Manufacturing and Applications
Architects around the world are using mass timber construction systems to build taller wood buildings, incorporate the aesthetic of exposed wood, or increase the amount of prefabrication on their projects. Many use CLT panels and glue-laminated timber (glulam) beams as the building structure, often as a carbon-friendly alternative to conventional materials such as steel, masonry and concrete. In this presentation by an Oregon-based CLT manufacturer, successful US projects will be highlighted to demonstrate the variety of commercial and multi-family applications available for CLT under today’s building codes. Topics will also include CLT manufacturing, benefits such as structural versatility, and potential future uses.

Cost Dialogues: The Contractor Perspective on Mass Timber Buildings
Ankit Sanghvi, DBIA, LEED-AP, PCL Construction Services, Christopher Evans, LEED AP, Swinerton Builders, Shawn Brannon, Adolfson & Peterson Construction
Innovation isn’t necessarily new, but it should always be better—and that’s certainly been the case for mass timber. Environmental performance, lighter weight, speed of construction and aesthetics are all cited as reasons for its use over traditional materials. However, one of the hurdles left before mass timber can become mainstream is cost. Cost of materials, manufacturer capabilities and efficiencies, erection processes, pre-planning and the level of prefabrication all play a role in the final cost of a mass timber project, and yet there is little widespread knowledge of these topics. This panel of three experienced installers and contractors will provide insight on the cost of real mass timber buildings in the US. Preconstruction planning, construction phasing, erection techniques and lessons learned will all be covered to help building designers assess the viability of their own mass timber projects.
