Abstract
BC Coastal mills will need to diversify the drying technologies currently used and consider new approaches in order to improve productivity, reduce drying costs, regain competiveness and continue to play a significant role in the increasingly stringent quality market for forest products. New demands for drying are related to energy efficiency, low environmental impact and of course, quality of the final product. The specific objectives of the project were: (1) to improve the conventional drying of 4.5” x 4.5” Douglas-fir lumber, (2) to evaluate the superheated steam/vacuum (SS/V) drying of 4.5” x 4.5” Douglas-fir lumber, (3) to develop a green sorting strategy for hem-fir lumber and (4) to determine the time required to reach 56°C in the core of 5¼ x 5¼ lumber using the requirements of CFIA PI-07 Heat Treatment schedule Option D - Generic Phytosanitary Heat Treatment Schedule, Heat Treatment with Moisture Reduction. The results showed that the drying time in conventional drying of 4.5” x 4.5” Douglas-fir lumber can be reduced by up to 25% without compromising the quality of the lumber. This can be achieved by increasing the temperature in the final drying stages and using lower relative humidity at the beginning of the drying process. In addition, final moisture content (MC) variation was reduced from 6.2% to 3.9%. Reductions of drying times from 26% to 41% were observed when drying 4.5” x 4.5” Douglas-fir under SS/V drying. Quality of the lumber at the end of drying was better when compared to the quality of the lumber at the end of conventional drying. In addition, specimens exhibited less final MC variation. Based on drying rate measurements of green hem-fir lumber dried to 9.0% MC, a new database was developed which in turn was incorporated into OASiS 2.0 software to evaluate different pre-sorting scenarios. Pre-sorting simulations allow end users to estimate the impact of kiln productivity, final MC distribution and drying degrade. The results showed that different correlations between the time to reach 19.0% MC and initial weight or initial MC could be established. The best correlation with an R square of 0.77 was made between initial weight and MC. After performing several simulations with the new database an optimum cut-off point of 65% yielded the best results in terms of potential increase of productivity and quality of the final product. Wood heating rate test results showed that CFIA Option D may be extended for 5¼ x 5¼ lumber as long as the dry-bulb = 71°C (= 160°F) for 36 hours at the end of the heat treatment. Total heat treatment time required, including the time required to reach 71°C (160°F), is 72 hours.

Abstract
This report is divided into six (6) subsections related to different building performance attributes. It presents a review of current design provisions as well as an investigation and identification of gaps in current knowledge with respect to performance criteria for wood-based building systems. Lastly, suggestions related to performance criteria are given with respect to, among others, structural, sound, vibration, fire, building enclosure, energy efficiency, durability and environmental performance. The development of such criteria is fundamental for reducing the burden on early adopters and AHJs in demonstrating regulatory acceptance of innovative building systems.

Abstract
Many sites in coastal B.C. have difficult planting conditions as a result of their remote mountainous terrain and helicopter- or boat-only access. The logistical challenges associated with planting containerized stock – seedling ordering and delivery logistics, stock thawing and handling requirements, time constraints, etc. – coupled with the difficulty of access, make reforestation in these remote sites a cumbersome and costly operation.

Abstract
Pour différentes raisons, les moisissures représentent un défi constant lors de la production de bois résineux et feuillus : santé, environnement, qualité et stratégies de production. Elles sont aussi une préoccupation constante pour les consommateurs et à l’origine de réclamations qui peuvent être très coûteuses pour les producteurs. Un sondage en 2014 dans l’Est du Canada révélait qu’en moyenne les coûts annuels liés à la détérioration biologique étaient de 60 000 $ par usine. Dans le cas d’une usine intégrée, spécialisée en transformation primaire et secondaire de feuillus et résineux, ces coûts avaient atteint près de 475 000 $ pour cette même année. Ces coûts sont liés à un ensemble de facteurs : modification du procédé, perte de productivité, réclamations, pertes de ventes (Gignac, 2015). Plusieurs facteurs peuvent contribuer au développement de moisissures dont la teneur en humidité du bois, les conditions climatiques et la durabilité naturelle propre à l’essence de bois. Avec les années, FPInnovations a acquis beaucoup de connaissances, accumulé beaucoup d’information, de données et de savoir-faire à travers ses projets de recherche et son soutien technique à l’industrie. En combinaison avec d’autres données disponibles dans la communauté scientifique, nous proposons de résumer l’information pertinente pour l’industrie et de la présenter sous forme de document de vulgarisation. Ce document se veut un outil simple et pratique pour le personnel de l’industrie de la transformation du bois afin de les soutenir dans la prise de décision concernant les stratégies d’entreposage, de séchage à l’air, séchage au séchoir, gestion du bois sec et transport jusqu’à sa destination finale, le consommateur. Ce document de référence regroupe les connaissances générales en lien avec les problématiques de moisissures.

Abstract
La coupe de jardinage 1-2-3 a d’abord été conçue comme solution sylvicole pratique et peu coûteuse pour une gestion efficace de peuplements résineux. À cause de l’historique de perturbations dans la plupart des forêts feuillues, plusieurs peuplements candidats n’ont pas la structure souhaitée entre les cohortes pour appliquer un traitement de jardinage conventionnel. L’approche Jardinage 1-2-3 propose une alternative qui peut être envisagée dans ces peuplements à structure débalancée. Dans le cadre des travaux de FPInnovations, des essais opérationnels ont été réalisés dans des peuplements à prédominance feuillue pour mesurer l’efficacité de la méthode 1-2-3 dans de telles conditions. Lors du déploiement opérationnel, les paramètres tels que le réseau de sentiers, le taux de prélèvement et la gestion de la vigueur des tiges furent respectés. La performance de l’opérateur de l’abatteuse était bonne au cours des essais, autant pour la productivité en termes de tiges ou de m³ récoltés par HMP. Bien que seule une mise en application à grande échelle puisse réellement en révéler le plein potentiel, les résultats de ces essais permettent de croire que la méthode de jardinage 1-2-3 convient bien à la récolte de forêts feuillues dont la structure ne se prête pas bien aux approches jardinatoires habituelles.

Abstract
Dans l’esprit des Guides sylvicoles développés par le Ministère des Forêts, de la Faune et des Parcs du Québec (MFFP), les coupes progressives deviennent un outil complémentaire en vue de traitement de la forêt mélangée. Une approche multitraitement (Meek et Lussier, 2008) est particulièrement appropriée pour le traitement des forêts mixtes, car les conditions y sont si variables qu’un seul ensemble de directives ne peut être appliqué sur une grande surface. En forêt mélangée, les proportions des essences varient beaucoup dans l’espace et le fait que la maturité de ces essences ne soit pas la même entrainent un niveau de complexité additionnel. La coupe progressive avec l’approche multitraitement fut proposée par FPInnovations pour ce type de forêt. L’approche multitraitement a un caractère clairement opérationnel. Elle vise à limiter les coûts et faciliter l’implantation de coupes partielles lorsque les conditions de peuplements sont particulièrement hétérogènes. L’approche proposée confie à l’opérateur de l’abatteuse le choix des tiges à prélever. Celui-ci analyse l’état de la forêt entourant son abatteuse et applique les actions prévues selon une liste de critères préparés pour le massif sous traitement. Il change d’action lorsque les conditions changent. Le présent rapport présente les résultats de plusieurs implantations d’approche multitraitement qui s’appuient sur la méthode 1-2-3 qui a déjà été décrites (Meek et Cormier, 2004; Meek, 2006; Meek et Lussier, 2008; Meek et Roy, 2009; Meek, Lussier et Roy, 2012).

Abstract
Traction-assist (also called winch-assist, or tethered-assist) technology for steep-slope harvesting and forest operations has increasingly been implemented worldwide over the past four to five years. Industry involvement and the need for relevant information in western Canada have dramatically expanded in the last year alone. FPInnovations attended the Western Region Council on Forest Engineering (WR.COFE) seminar in January 2016, where one of the technical sessions focused on steep-slope tethered-assist technology. More than 300 attendees received updates from an academic (Oregon State University), a manufacturer (Summit Attachment & Machinery), a contractor (Technical Forest Solutions), a regulator (Oregon Occupational Safety and Health Administration), and a cable logging specialist(Brian Tuor)

Abstract
In 2015, FPInnovations initiated a research program to explore potential uses of low-cost unmanned aerial system (UAS) or drone technology for the Canadian forest industry. To date, uses for the technology have been identified by forest industry stakeholders from simple mapping to visual reconnaissance of forestry activities in forest operations. In October 2015, FPInnovations observed a UAS being used to supplement a safety auditing process. The safety audits took place at Lemare Lake Logging, a large stump-to-dump logging contractor currently operating on the mid-coast of British Columbia. In the coastal forest industry, manual tree falling is the first step for old-growth tree removal on steep ground. To ensure that safe work practices are adhered to at all times during falling operations, WorkSafeBC regulations require that fallers be audited on a regular basis while they are working.

Abstract
There is a need to demonstrate how novel timber-concrete composite floors can span long distances and be a practical alternative to other traditional structural systems. Better understanding of the fire behaviour of these hybrid systems is essential. To achieve this, the fire-resistance of a timber-concrete composite floor assembly, using BC wood products, will be evaluated in accordance with CAN/ULC-S101 [2]. A 2 hr fire resistance rating will be targeted, as this is the current requirement in high-rise buildings for floor separations between occupancies. The structural behaviour of this type of system will also be assessed from conducting pull-out tests of the shear connectors. In conjunction with previous test data, the results of this test will be used to develop an analytical model to assess the structural and fire-resistance of timber-concrete composite floors. 301010618
