Abstract
Given the continuing efforts underway to develop the market for the use of mass timber in building construction (FPInnovations, 2014), restoring the use of timber in bridges can complement this effort and help to provide more opportunities for the developing mass timber supply chain.

Abstract
Manufacturing equipment ranges from manual, semi-automated to fully automated. Software developers have developed suites of applications for structural design, computer aided design/drafting (CAD), computer aided manufacturing (CAM), building information modeling (BIM), and communication protocols to link production machineries. To further improve production process and material handling, it is essential to rationalize the sectors, review the current status, and identify technology gaps.

Abstract
The biomass yield per hectare predicted for the Prince George TSA is 25.7 oven-dried tonnes per hectare (odt/ha) from harvest residues. Over the next 20 years a total of 14.5 million odt of available biomass could be generated by harvest in the Prince George TSA, or approximately 725,000 odt/yr. Of this, 23%, approximately 3.3 million odt in total, or 165,000 odt/yr, is expected to be available at the economic price of $60 per oven-dried tonne. Delivery of biomass from the most expensive (distant) block is projected at $163/odt and the average delivered price for all biomass is $73.72/odt. Delivery locations were the mill sites at Prince George, Dunkley, Bear Lake, Vanderhoof, and Fort St. James.

Abstract
The biomass yield per hectare predicted for the Williams Lake TSA is 22.5 oven-dried tonnes per hectare (odt/ha) from harvest residues. Over the next 20 years a total of 8.3 million odt of available biomass could be generated by harvest in the Williams Lake TSA, or approximately 414,000 odt/yr. Of this, only 2%, approximately 169,000 odt in total, or 8,500 odt/yr, is expected to be available at the economic price of $60 per oven-dried tonne. Delivery of biomass from the most expensive (distant) block is projected at $160/odt and the average delivered price for all biomass is $99.02/odt. Delivery location was the mill site at Williams Lake, and for the scenario a location was added at Anahim Lake. If biomass is delivered to Anahim Lake, the economic amount could increase by 8.6 times.

Abstract
The biomass yield per hectare predicted for the Cranbrook TSA is 18.0 oven-dried tonnes per hectare (odt/ha) from harvest residues. The biomass ratio, which is the ratio of recovered biomass to recovered merchantable roundwood, is estimated at 31.2%. Over the next 20 years a total of 1.16 million odt of available biomass are predicted to be generated by harvest in the Cranbrook TSA, or approximately 58,000 odt/yr. Of this, 76%, approximately 879,000 odt in total, or 44,000 odt/yr, is expected to be available at the economic price of $60 per oven-dried tonne. Approximately 99% of the total predicted volume is expected to be available at $90/odt: a total of 1.15 million odt, or 57,550 odt/yr. Delivery locations modelled were the mills at Cranbrook, Skookumchuk, and Elko.

Abstract
n collaboration avec l’Université de Victoria, on a mis au point un mur de cisaillement à haute capacité comportant deux rangées de clous au périmètre du revêtement. On a mené un programme d’essais pour évaluer la performance du mur de cisaillement proposé, ce qui comprend la résistance aux charges latérales et aux déplacements, le comportement hystérétique, la rigidité et la ductilité.

Abstract
The widespread availability of genomics data and molecular tools for pathogen detection and identification provides scientists and regulators a powerful toolbox for pathogen monitoring. However, this raises questions and concerns regarding the use of these tools in import and export of forest commodities. Discussions around implementation and standardization have highlighted knowledge gaps around their efficacy and suitability in wood and their applicability to forest commodities. This study compared detection efficacy of various emerging tools on artificially infected forest and wood commodities, focusing on Phytophthora pathogens, an important group of invasive and sometimes difficult to detect species. In situ detection was more sensitive than traditional isolation, and for some methods, 100% of infected samples were positive. Detection efficacy varied by tissue type and detection method. The data generated from this study is important in addressing knowledge gaps around pathogen detection in wood.
