Résumé
This review explores the benefits, challenges, limitations, logistics, and cost-effectiveness of different management options to convert conifer-dominated stands to aspen-dominated stands. These alternatives can include overstory removal (harvesting, bulldozing, shear blading, prescribed burning) and site preparation (root trenching, drag scarification, broadcast burning) treatments. On sites where parent aspen trees are not present in the original stand, tree planting will be necessary albeit costly in comparison to regeneration by suckering. While extensive literature exists on the regeneration of trembling aspen through suckering, research on artificial establishment with seedlings and its requirements is still in its infancy and rapidly developing.

Résumé
Hosted by Edouard Proust, this presentation by David Bevly held on February 10, 2021 highlights an important component of FPInnovations' Transportation and Infrastructure group's work. The concept of truck platooning, inspired by pelotons of cyclists and originally developed for highway use to obtain fuel savings, utilizes technology to maintain the desired distance between trucks by controlling acceleration and braking, and the relative lateral position of the vehicles by steering, reacting faster than a driver can. Truck platooning has attracted the attention of the natural resources sector and its implementation is expected to increase the productivity of drivers. By allowing the operation of driverless following trucks replicating the path set by the human operated leader vehicle, the concept could help mitigate the workforce shortage that impact the sector while supporting the supply of lumber to mills across the country.
Résumé
Ce contenu est exclusivement en anglais. Merci de contacter notre équipe si vous souhaitez obtenir de l’information en français. Cette présentation de David Bevly a été organisée le 10 février 2021 par Edouard Proust. Elle met en lumière une composante importante du travail effectué par le groupe Transports et Infrastructures de FPInnovations. Le concept d’opération de camions en peloton est inspiré des pelotons de cyclistes et a été mis au point à l’origine pour des applications autoroutières avec pour objectif une réduction de la consommation de carburant. Les camions sont équipés d’une technologie permettant le contrôle de l’accélération, du freinage et de la direction offrant la possibilité de maintenir la distance de suivi entre les véhicules ainsi que leur positionnement latéral relatif. En autorisant la mise en œuvre de camions suiveurs entièrement autonomes et qui répliquent le tracé du camion de tête opéré par un chauffeur, le concept pourrait à terme aider à minimiser l’impact du manque de chauffeurs dans l’industrie tout en supportant l’approvisionnement en fibre des scieries à travers le Canada.

Résumé
The clean air initiative led by the British Columbia Ministry of Environment seeks to develop innovative methods to improve community air quality by utilizing harvest residues and minimizing the volume of fibre burned at roadside. Retaining processed tops as roadside oriented piles is proposed as an alternative to burning debris. These burn trials have demonstrated that in this unique arrangement of fuels and interaction of site-specific variables, particular areas of the piles will be more vulnerable to ignition sources which can lead to sustained burning and high intensity fire behaviour. In addition to the low fuel moisture conditions, other fuel properties, such as the close proximity of piles, high volume of fine fuels (branches and needles) and orientation of piles to road all contributed to enhanced burning at this site.

Résumé
Building high energy efficiency has become a must to reduce carbon emission from the built environment and to meet needs of consumers. Industrialized construction provides an effective way to produce highly insulated and airtight building envelopes to achieve superior building performance, such as Net Zero Energy. However, it is important that as other attributes (e.g., seismic, wind, fire, vibration, etc.) are being addressed, further research is needed to develop well rounded building envelope solutions. Meanwhile, improvement may be made in automated production equipment and software to optimize and monetize these solutions.

Résumé
Il est devenu indispensable de construire des bâtiments à haute efficacité énergétique pour réduire les émissions de carbone dans l’environnement et répondre aux besoins des consommateurs. La construction industrialisée est un bon moyen de produire des enveloppes de bâtiment bien isolées et étanches à l’air et, par le fait même, d’accroître la performance énergétique des bâtiments (p. ex consommation énergétique nette zéro). Cependant, il est important de tenir compte d’autres attributs (p. ex. charges sismiques, vent, feu, vibrations, etc.). Il faudra poursuivre les recherches pour trouver des solutions durables en matière d’enveloppes de bâtiment. Entre-temps, il est possible d’améliorer l’équipement de production automatisée et le logiciel qui l’accompagne afin d’optimiser et de rentabiliser ces solutions.

Résumé
The USDA Forest Service’s Qualified Product List (QPL) provides guidance on the range of permissible mix ratios for water-enhancer products. Due to the proprietary nature of water-enhancer products, there are several unknowns about the rheology of the permissible mix ratios. This study focused on mapping the viscosity of various suppressant products as a function of their mix ratios. The results revealed a wide range of viscosities across products, with each product showing a different non-linear relationship with different mix ratios. The results from this study can help understand the optimum viscosity range to achieve desired drop characteristics during aerial operations.

Résumé
These concealed or void space cases require installation of elements which represent additional material cost and labour. For wood buildings that rely heavily on prefabrication, these steps can have a significant impact on scheduling. Removing dependence on concrete and gypsum board in certain applications could make wood buildings more cost competitive to similar buildings of steel and concrete and could further enhance the benefits of prefabricated construction.

Résumé
Currently, mass timber building designs commonly incorporate a concrete floor topping. This can improve building accoustics by increasing the mass of the assembly, reduce floor vibration and create a smooth flat surface to install finish flooring on. The installation of concrete requires formwork, pouring and finishing the concrete and time to cure which adds to project schedules. One way to address this is to use mass timber elements that are prefabricated with concrete toppings preinstalled. Replaceing the concrete floor toppings wiht dry alternatives, such as cement board, may also reduce construction timelines, while still ensuring adequate acoustic and vibration performance. Cement board needs only to be screwed in place and can be walked on immediately after installation; this reduction in construction time may reduce overall project costs and help make wood buildings more cost competitive than other types of construction.

Résumé
Cross-Laminated Timber (CLT) is an engineered mass timber product manufactured by laminating dimension lumber in layers with alternating orientation using structural adhesives. It is intended for use under dry service conditions and is commonly used to build floors, roofs, and walls. Because prolonged wetting of wood may cause staining, mould, excessive dimensional change (sometimes enough to fail connectors), and even result in decay and loss of strength, construction moisture is an important consideration when building with CLT. This document aims to provide technical information to help architects, engineers, and builders assess the potential for wetting of CLT during building construction and identify appropriate actions to mitigate the risk.

Résumé
Le bois lamellé-croisé (CLT) est un produit massif de bois d’ingénierie qui est fabriqué à partir de multiples pièces de bois de dimension assemblées en couches orthogonales avec des adhésifs structuraux. Ce produit est conçu pour des conditions de service sèches et est couramment utilisé pour construire des planchers, des toits et des murs. Comme l’humidification prolongée du bois peut causer des taches, de la moisissure, des variations dimensionnelles excessives (parfois suffisantes pour provoquer la défaillance des attaches), et même la pourriture et la perte de résistance, l’humidité est un facteur important dans la construction avec le CLT. Le présent document a pour but de fournir de l’information technique pouvant aider les architectes, les ingénieurs et les constructeurs à évaluer les risques d’humidification du CLT pendant la construction de bâtiments et à prendre les mesures appropriées pour atténuer ces risques.
