Canadian expert for international timber bridge conference

6 May 2025

The International Conference on Timber Bridges, to be held in Rotorua, New Zealand, in June, will include a competition for design and building of model timber bridges.

David Moses, Canadian timber bridge expert, will be a keynote speaker at the International Conference on Timber Bridges, in Rotorua, New Zealand, in June. He will talk on “Breathing New Life into Timber Bridge Engineering in Canada”

David is the founder of Moses Structural Engineers a Toronto-based firm whose core purpose is a “Lasting Impact” on cities and communities. David has over 25 years of experience in structural engineering design of many large timber structures and bridges across Canada and the United States.

David will present recent timber highway bridges and pedestrian bridges, new and restored, across Canada, showcasing the engineering and craft of timber engineering.

David says that “many new timber bridges have been built in recent years – these serve as examples that inspire a new generation of bridge designers to consider building with wood.”

The conference in Rotorua is expected to have 200 participants, with more than 40 papers on many aspects of design and construction of timber bridges, for main highways, railways, walkways, and cycle tracks.

    Welcome

    Greetings from your WoodWorks news team. We have a case study of the Court Theatre rebuild in Christchurch and how addressing the design-construction gap led to increased efficiency. From ANZ we have statistics showing a decline in the New Zealand construction sector. The SH26 Onetai Stream Bridge, New Zealand’s first modern timber bridge has been completed. From the French Pyrenees a self sufficient back country ‘hut’ has been reimagined with CLT pieces flown in by helicopter, hopefully the photos will inspire readers from DOC’s design team. Lastly, David Moses, a Canadian timber bridge expert, will be a keynote speaker at the International Conference on Timber Bridges in Rotorua this June.

    Builders and installers of mass timber structures can enhance productivity and reduce risks by addressing the design-construction gap. Many builders overlook this gap as an opportunity, often pushing trade coordination and shop drawings downstream to suppliers, leading to costly on-site issues. Builders who engage in technical coordination alongside timber shop drawings can achieve greater efficiencies, avoiding redundancy and enhancing project outcomes.

    In Q4, construction activity contracts saw a decline, with overall building work decreasing by 4.4% quarter-on-quarter. Residential work fell by 4.9%, while non-residential activity decreased by 3.1%.

    The SH26 Onetai Stream Bridge, New Zealand’s first modern timber bridge has been completed. To replace the deteriorating old bridge this project involved a full highway closure to facilitate construction. All bridge elements – full precast abutment beams, settlement slabs, retaining wall blocks, glulam timber beams, and plywood decking — were fabricated entirely offsite.

    At an elevation of 1866 meters in the French Pyrenees, the Wallon Marcadau Refuge has been reimagined—a fusion of tradition and modern timber construction. With no access roads, an earthquake-prone location, and extreme weather conditions, the project was a logistical masterpiece.

    Lastly, David Moses, a Canadian timber bridge expert and founder of Moses Structural Engineers, will be a keynote speaker at the International Conference on Timber Bridges in Rotorua, this June. He will discuss “Breathing New Life into Timber Bridge Engineering in Canada,” showcasing recent timber highway and pedestrian bridges across Canada.
