Some Symbolism in Historic French Carpentry
This presentation structures observations made on my recent 2018 travels in France about the evolution of overhanging roof dormers and what they say about the development of the individual craftsperson in society. Guitardes and capucines display a complexity and, sometimes, seeming frivolity of design usually associated with political, economic, or ecclesiastic architecture. Interpretation in their historical contexts, however, shows a... read more

The History of Agriculture as Told by Barns
The evolution of barn architecture tells the story of New Hampshire agriculture. Barns changed from the early English style, to Yankee style, to gambrel and then pole barns to accommodate the changing agriculture. This presentation will be a chronological walk through time, with photo illustrations of barns around the state that are examples of these eras of agricultural history. read more

Dry Stone Walls and Foundations: Evaluating, Repairing and Building
Learn about what to look for when evaluating the structural stability of old dry stone walls, retaining walls, and foundations. Understand methods for repairs and the hands on do’s and don'ts when building structural stone walls without mortar. We will also touch on using lime mortar when mortar is appropriate. read more

Chris Carbone

Fire and Timber
Chris will cover the basic dynamics of fire and flame spread, and how timber performs when exposed to fire conditions. Heavy Timber (type IV construction) has been recognized as a good performing structural system due to the size of the members and their inherent ability to develop protective charring as fire progresses. Unlike other structural materials, that char... read more

Preservation Timber Framing

Using the National Register as a Preservation Strategy
Preservation of buildings, landscapes and open places is usually undertaken at in individual level. In many instances one person or family works to save a building out of personal desire. But how do you get a larger group, for example, a neighborhood, to embark on a mission of preservation when each building is individually owned? Many times... read more

A Computational Tool for Determining Design Values
As demonstrated by Tom Nehil and Ron Anthony in TFEC Technical Bulletin 11 and Tom’s article in issue #127 of Timber Framing, it is possible to generate design values for lumber and timber species that are not listed explicitly in the NDS Supplement. The approach relies on the computational procedures embedded in ASTM Standard D245 – Standard Practice for... read more

A Truly American Form: Anglo Dutch Houses their Roots, Form and Legacy
A new house form arose in the later years of the 18th century, in the areas formally comprised of New Netherland and the adjoining land in the North Eastern US. This house form would become a common sight in New England and much of the North in the first half of the 19th Century. This talk will focus on the... read more

Why Your Two Hundred Year Old Timberframe Doesn't Meet Current Code
“Over engineered.” The phase often used by a timberframer to express their frustration with the reviewing engineer, one that is often driven by a divergence in design priorities. A representation of a historic craft versus the legal minutia of code expectations and lawsuit liability. This quagmire only becomes more muddled with the continued evolution and expectations of timberframe... read more

Unconventional Timber Framing
Traditional timber framing is long steeped in traditional vernacular for timber layout, sizing, and joinery - be it the story-and-a-half capes from New England, canted queen post barns throughout the Midwest or half-timbered houses of Europe. With the advent of computer design software removing the designer from the traditions of the past, designs are straying more and more from the... read more

Preserving Old Barns
John Porter has written a second edition of his book: Preserving Old Barns. It is a testament to the preservation of barns and farms across New Hampshire. John spent his career at the NH cooperative extension working directly with farmers to keep their farms viable and their buildings repaired and efficient. This new book expands into the best... read more

Blenheim Covered Bridge – Innovations in Construction and Reconstruction
This presentation will address the Blenheim Covered Bridge in North Blenheim, NY, originally built by Nicholas Powers in the 1850’s. We will discuss the history of how the bridge was constructed and the innovative approach to the design and construction methods utilized at that time. This bridge is a contender for the title of the longest single span covered... read more

Reflections on Timber Framing Past and Future
After founding Timber Framing at the dawn of the Guild and editing 127 quarterly issues, Ken Rower will reflect on the evolution of our quarterly journal and lessons learned along the way. What makes a good topic for a journal article? Has this changed over time? Michael Cuba and Adam Miller, current journal editors, will join Ken to provide perspective... read more

Volunteerism in Historic Preservation
The future of historic preservation in the United States is being threatened due to the economic and political realities of consistent budget cuts coupled with a decrease of skilled labor. Currently, the practice of historic preservation is portrayed as a monumental undertaking requiring an immense amount of training and education to become involved. Realizing this outlook as well as an... read more

The Roofs of Notre Dame, Paris.
Having spent many hours in the 1980s recording the roofs of Notre Dame, I feel the destruction of the medieval carpentry like a personal loss. Roofs above the high vaults of medieval cathedrals were never meant to be seen; yet, ironically the world just saw the timberwork ablaze against the evening sky. For those interested in historic carpentry, the... read more

New Skin for Old Bones: Enclosing Antique Timberframes
The design and installation of building envelopes around antique timberframes can be a complicated job. Driven by the deep experience of Foard Panel's installers and designers, this session will discuss some of the most common "situations" tradesmen and designers encounter. Most of the time, an antique frame is being restored to fit a different purpose. Large barn frames can... read more

Evolution of Workflows: From Paper and Framing Squares to Digital Transfer of Building Data
The timberframe community is uniquely suited to take advantage of offsite construction and to do more with it than build boxes. In this presentation, timber framers will be challenged to tap into their existing skill set and imagine how a structure could come together without the use of a traditional frame. What if components could be assembled without the use... read more

New Tall Wood Code Provisions: Understanding Advanced Design Topics
In January 2019, the International Code Council (ICC) approved a set of proposals to allow tall wood buildings as part of the 2021 International Building Code (IBC). Based on these proposals, the 2021 IBC will include three new construction types—Type IV-A, IV-B and IV-C—allowing the use of mass timber or noncombustible materials. These new types are based on the previous... read more

Turning Focus Away from Emissions and Towards Sequestration
It’s accepted wisdom that building more energy efficient enclosures is good for the environment. But what if it isn’t? What if, as energy efficiency standards rise, the actual embodied energy of the materials we use during construction has a bigger short term impact than the emissions of the energy used to condition the building during it’s lifetime? Can we make... read more
