Clouston, Schreyer Co-Author Definitive Guide on Mass Timber Materials, Design and Construction

February 6, 2026February 5, 2026 by Alexander Schreyer Comment Closed

Peggi L. Clouston and Alexander C. Schreyer, professors in the Building and Construction Technology program at UMass Amherst and experts in wood engineering, have written a comprehensive new book, “Mass Timber: Materials, Design, and Construction,” an extensive 576-page volume that serves as a one-stop resource for the rapidly evolving field of mass timber construction. Published by John Wiley & Sons, the book arrives at a critical time as the architecture, engineering and construction (AEC) industry increasingly turns to sustainable wood products to reduce the carbon footprint of the built environment. Clouston and Schreyer’s book bridges the gap between traditional timber knowledge and modern engineering, covering a wide array of topics essential for students and professionals alike, including: Sustainability: Exploration of the climate-related benefits of wood and forest health Material Science: In-depth technical details on Cross-Laminated Timber (CLT), Glulam, and structural composite lumber Practical Design: Guidance on building codes, gravity and lateral loads, and complex connection detailing Construction Excellence: Insights into procurement, risk management, and on-site hoisting and storage. The book also...

In Memoriam: John W. Olver

March 9, 2023March 7, 2023 by Alexander Schreyer Comment Closed

The John W. Olver Design Building - BCT's home on the Amherst campus - is not just another campus building. The beauty and warmth of the timber structure, and its environmental footprint that treads lightly, represents a visionary approach to contemporary building design in that it integrally respects the responsibility we have towards the earth we live on. None of this would have been possible without the support and environmental consciousness of Congressman John Olver, who was the prime reason that the Olver Design Building was built with Mass Timber, the only naturally renewable building material. John attended a presentation by Peggi Clouston in 2014 about Mass Timber which led to several more meetings and ultimately a meeting of the minds where our technical background combined with John’s long term efforts to support forest health, sustainable construction, and rural economies. Our conversations ultimately led to the idea of creating a timber demonstration structure which would support the UMass Amherst climate action plan and...

MoMA Panel Discussion on Mass Timber with Prof. Clouston Now Available

May 20, 2022May 19, 2022 by Alexander Schreyer Comment Closed

A presentation and panel discussion on "Material Worlds: Mass Timber" was organized by the Museum of Moden Art in New York on Dec 14, 2021 and included BCT Prof. Peggi Clouston. From the MoMA website: Wood construction is ancient, and surprisingly more relevant than ever before. The United Nations predicts that nearly one Manhattan worth of floor area will be built every two weeks globally over the next 40 years (GlobalABC, IEA, and UNEP 2018). Since the built environment is responsible for almost half of global carbon emissions, it is essential that we redesign what these cities are made of. Mass timber laminates small pieces of wood into scalable structural elements that have strength comparable to concrete and steel, enabling urban density, a key component in a low-carbon way of life. It has the potential to be more renewable and carbon-sequestering than any other structural material in existence. But questions remain. Who has access to healthy building materials like this? Are there enough...

Tedd Benson speaks about a better way to build in the 21st Century

November 11, 2020September 25, 2022 by . BCT . Comment Closed

Tedd, founder of Bensonwood (1973) and Unity Homes (2012), has devoted his life to developing a better way to build. A key figure in the revival of timber framing in America, he was one of the founders of the Timber Framers Guild of North America (1984) and authored four books on the subject. Through the decades, Bensonwood established itself as a creative leader in timber frame design, engineering, craftsmanship, and CAD- CAM technology. This work has taken the company to nearly every state in the U.S. (Oklahoma is a holdout), as well as Canada, England and Japan. After having spent many years with the Bensonwood team developing processes, systems, logistics, and technology, Tedd went on to found Unity Homes, now a sister company, with the objective to make high performance homes affordable and normal. Today, Bensonwood continues to lead the industry, pioneering the use of Mass Timber and CLT’s in buildings large and small, and collaborating on innovative projects to...
