Abstract
In the construction of buildings, the timber-concrete (TCC) system can be a cost-competitive solution for floors with longer spans, since the mechanical properties of the two materials are used efficiently. Furthermore, the additional mass from the concrete improves the acoustic performance compared to a timber floor system alone. Nevertheless, TCC floors are not commonly used in buildings in Canada, due to the absence of technical guidelines for such types of structural systems in this country.

Abstract
There is a need to evaluate TCC systems under fire conditions to understand how shear connectors will perform and might affect the fire performance and the composite action of the assembly. This project evaluates the fire performance of TCC assemblies based on their structural resistance, integrity and insulation when exposed to a standard fire, as well as how mass timber and concrete interact. This study involves full-scale fire resistance tests on composite wood-concrete floors using two types of shear connectors. 301009649

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

Abstract
Canada’s northern forested landscapes feature numerous wetlands, such as fens, bogs, and swamps that present environmental and operational challenges for resource roads. The effects of these roads on the many ecological functions of wetlands are of increasing concern to Canada’s resource industries, governments, northern communities, and conservation organizations. Among the difficulties in the planning and construction of resource roads which cross wetlands are the low bearing capacity of the subgrade material and the placement and installation of adequate drainage and water-crossing structures. However, both wetlands and resource roads should be able to function with careful planning, knowledge of the various wetlands and their ecological functions, and the development and use of best management practices. FPInnovations, in partnership with EACOM Timber Corporation, undertook a study to assess a method for improving culvert foundations (Partington 2014, 2015). At the study site, the poor bearing capacity of the deep organic soils is a particular challenge that required improved culvert foundation techniques. It was known that in other areas of Canada biaxial geogrids have been used in an attempt to reinforce the culvert foundation. The forest company and contractor decided that at this site, since the geogrid was going to be used as subgrade reinforcement in the road, it would also be installed directly under two of the culverts while the remaining culverts would be installed on the forest floor with no provision for an improved foundation (see Figure 1). On soft, compressive soils like this, the entire road embankment is expected to settle; the amount will depend on the fill thickness (i.e., total mass of the fill) and on the bearing capacity of the native soils. Geosynthetics are often used to help minimize differential settlement by bridging weaker sections along the road. It was believed that the geogrid could act as a type of hammock by supporting the culvert and preventing any significant settlement due to the dead load of the road fill material. In addition, a woven geotextile was placed under the geogrid, a practice that was standard for the operations at this site.

Abstract
L'environnement forestier du nord du Canada compte de nombreux milieux humides, tel que des marécages, des tourbières et des marais, représentant des défis sur le plan environnemental et opérationnel pour la construction de routes d'accès. Les effets de ces routes sur les nombreuses fonctions écologiques des zones humides constituent une préoccupation grandissante pour l’industrie, les gouvernements, les collectivités du Nord et les organismes de conservation du Canada. La faible capacité portante des sols, le choix de l’emplacement ainsi que l’installation adéquate des structures de drainage ou traverses de cours d’eau sont des exemples de défis associés à la planification et à la construction de routes en zone humide. Cependant, grâce à une bonne planification jumelé à une connaissance des zones humides et de ses fonctions écologiques, ainsi que l’utilisation de pratiques exemplaires de gestion, il est permis de croire que les zones humides et les routes d'accès peuvent fonctionner comme il se doit en cohabitation. FPInnovations, en partenariat avec EACOM Timber Corporation, a entrepris une étude visant à améliorer la fondation des ponceaux (Partington, 2014, 2015). Sur le site à l'étude, la faible capacité portante du sol organique profond représentait un défi de taille nécessitant des techniques supérieures de construction des fondations des ponceaux. Dans d'autres secteurs du Canada, on a utilisé des géogrilles biaxiales pour tenter de renforcer les fondations des ponceaux. L’entreprise forestière et l’entrepreneur ont décidé que, sur ce site, étant donné que la géogrille était utilisée dans la base de la route, elle serait installée directement sous les deux ponceaux, tandis que les autres ponceaux seraient installés directement sur le tapis forestier, sans amélioration de la fondation (voir Figure 1). Le tassement (enfoncement) total de la voie en remblai est à prévoir sur des sols mous comme celui-ci, et il varie en fonction de l’épaisseur du remblai (masse totale du sol) et de la capacité portante du sol existant. Les géosynthétiques sont fréquemment utilisés pour minimiser tassement différentiel, en effectuant des pontages là où la route est plus faible. La géogrille fut utilisé pour créer l’effet « hamac » visant a supporter le ponceau, et ainsi empêcher tout tassement supplémentaire en raison du poids mort associé au matériau de remplissage de la route. De plus, un géotextile tissé a été placé sous la géogrille; il s’agit d’une pratique normalisée pour ce site.
