Summary
The CLT Handbook provides vital “How to” information on CLT for the design and construction community, and is a great source of information for regulatory authorities, fire services and others. The CLT Handbook is also a good textbook for university level timber engineering courses. In summary, the Canadian CLT Handbook will remain the most comprehensive reference for sharing the latest technical information on North American CLT. The Canadian edition of the CLT Handbook, first published in 2011 under the Transformative Technologies Program of the Natural Resources Canada, played an imperative role in accelerating the use and acceptance of CLT in North America. Its introduction subsequently led to the publication of the US Edition. The Canadian Edition supported the early use of CLT products from Canadian manufacturers in many small to large projects across Canada and the US, and paved the way for CLT and other wood products to be used in new applications like tall and large buildings, and bridges. Since then, additional research has taken place globally and substantial regulatory changes have occurred enabling more wood to be used in construction. Those developments highlighted a need for the CLT Handbook to be updated. The 2019 Edition of the CLT Handbook, for example, augments the recently developed CLT provisions in CSA Standard in Engineering Design in Wood and it includes a design example of an 8-storey CLT building. It helps expand the knowledge base of the designers about CLT enabling them to develop alternative solutions for taller and larger buildings that are beyond the boundaries of the acceptable solutions in building codes.

Summary
This guide provides reference data and methodology advice for cost engineering activities directly and indirectly associated with the design, procurement and installation of wood structures in Australia, especially with reference to mid-rise buildings (four or more levels). There has been a rapid growth in the use of Engineered Wood Products (EWPs) across the property industry. Since the delivery of Australia’s first mid-rise contemporary wood building – Forté Living from Lendlease – structural wood products have been used to construct a variety of buildings across the country. This trend has been supported by amendments to the National Construction Code (NCC), which since 2016 has provided a Deemed-to-Satisfy (DtS) solution for timber construction to an effective height of 25 metres (from 2019 applicable to all building classes), and has been further backed by the WoodSolutions free advisory program in this field. While many detailed guides have been published on the design and maintenance of timber structures, there has been relatively little focus on the specifics of costing and ultimately building them. This guide has been prepared to address the specific cost-related knowledge and approach that needs to be considered throughout the development process, with respect to the Australian Cost Management Manual and other relevant publications. Written in conjunction with Rider Levett Bucknall, a leading independent organisation in cost management, quantity surveying, project management and advisory services, this guide has been divided into sections associated with the typical activities of a cost engineer. While each section is complete on its own, the reader will gain most benefit by considering them to be inter-related, and it is recommended that the document is read as a whole. This guide refers to projects that are based on either individual Wood Products or systems, or their combinations. Further information on the nature, performances and design of such products and systems can be found, with a comprehensive and comparison-based approach, in WoodSolutions Technical Design Guide #46 Wood Construction Systems. Other guides within the WoodSolutions library offer more detailed information specific to a given application.

Summary
Fire separations and fire-resistance ratings are often required together but they are not interchangeable terms, nor are they necessarily mutually inclusive. The National Building Code of Canada (NBC)1 provides the following definitions: A fire separation is defined as “a construction assembly that acts as a barrier against the spread of fire.” A fire-resistance rating is defined as “the time in minutes or hours that a material or assembly of materials will withstand the passage of flame and the transmission of heat when exposed to fire under specified conditions of test and performance criteria, or as determined by extension or interpretation of information derived therefrom as prescribed in [the NBC].” In many buildings, the structural members such as beams and columns, and structural or non-structural assemblies such as walls and floors, are required to exhibit some degree of resistance to fire in order to prevent the spread of fire and smoke, and/or to minimize the risk of collapse of the building in the event of a fire. However, fire separations are assemblies that may or may not be required to have a specific fire-resistance rating, while structural members such as beams and columns that require a fireresistance rating to maintain the structural stability of a building in the event of a fire are not fire separations because they do not “act as a barrier against the spread of fire.”

Summary
In recent years, the science and engineering for controlling sound transmission in buildings have shifted from a focus on individual assemblies such as walls or floors, to a focus on performance of the complete system. Standardized procedures for calculating the overall transmission, combined with standardized measurements to characterize sub-assemblies, provide much better prediction of sound transmission between adjacent indoor spaces. The International Standards Organization (ISO) has published a calculation method, ISO 15712-1 that uses laboratory test data for sub-assemblies such as walls and floors as inputs for a detailed procedure to calculate the expected sound transmission between adjacent rooms in a building. This standard works very well for some types of construction, but to use it in a North American context one must overcome two obstacles – incompatibility with the ASTM standards used by our construction industry, and low accuracy of its predictions for lightweight wood or steel frame construction. To bypass limitations of ISO 15712-1, this Guide explains how to merge ASTM and ISO test data in the ISO calculation procedure, and provides recommendations for applying extended measurement and calculation procedures for specific common types of construction. This Guide was developed in a project established by the National Research Council of Canada to support the transition of construction industry practice to using apparent sound transmission class (ASTC) for sound control objectives in the National Building Code of Canada (NBCC). However, the potential range of application goes beyond the minimum requirements of the NBCC – the Guide also facilitates design to provide enhanced sound insulation, and should be generally applicable to construction in both Canada and the USA. This publication contains a limited set of examples for several types of construction, to provide an introduction and overview of the ASTC calculation procedure. Additional examples and measurement data can be found in the companion documents to this Guide, namely NRC Research Reports RR-333 to RR-337. Furthermore, the calculation procedure outlined and illustrated in this Guide is also used by the software web application soundPATHS, which is available for free on the website of the National Research Council of Canada (see the references in Section 7 of this Guide for access details).

Summary
This guide was developed by FPInnovations and its partners to assist in the design and construction of durable and energy-efficient wood-frame buildings in Alberta. The Province adopted the National Energy Code for Buildings 2011, as of November 1, 2016, in order to comply with the energy-efficiency requirements for large buildings (Part 3). It is now also possible, with new building regulations, to build wood structures with a maximum of six storeys or 18 m height in Alberta. This guide aims to provide solutions for the building envelope (enclosure) of Part 3 wood buildings, particularly five- and six-storey wood-frame buildings, to meet the prescriptive thermal requirements of the new energy code. A range of wood-based exterior wall and roof assemblies are covered, based on light wood frame or mass timber, and various thermal insulation materials are discussed. Effective R-values are calculated based on typical thermal insulation values of commonly used materials. This document also covers key considerations for building envelope design to maintain long-term durability in Alberta’s varied climate.

Summary
This chapter provides information related to commonly used wood construction methods (i.e., light-frame, post-and-beam, and mass timber) and mass timber products. It briefly discusses the manufacturing of four major lumber-based mass timber products (i.e., glue-laminated timber, nail-laminated timber, dowel-laminated timber, and cross-laminated timber), and their available dimensions and typical applications. The discussion also addresses primary lumber products, such as dimension lumber, machine stress-rated lumber, and finger-joined lumber, which are the building blocks from which mass timber products are manufactured. Advantages of using wood in construction are illustrated by examples largely from North American practices. The life cycle assessment concept is also introduced.

Summary
The rate at which flame spreads on the exposed interior surfaces or a room or space can have an impact on the rate of fire growth within an area, especially if the materials of the exposed surfaces are highly flammable. Therefore, the National Building Code of Canada (NBC) regulates the surface flammability of any material that forms part of the interior surface of walls, ceilings and, in some cases, floors, in buildings. Based on a standard fire-test method, the NBC uses a rating system to quantify surface flammability that allows comparison of one material to another, and the ratings within that system are called flame-spread ratings (FSR).

Summary
Mass timber and CLT construction offers many advantages, such as enhanced modularity, reduced construction schedules, improved thermal performance, and material sustainability. However, mass timber’s propensity to absorb moisture from the environment and the relative vapor impermeability of CLT panels introduces unique challenges when incorporated with the building enclosure. These challenges should be considered during design and construction phases to ensure long-term performance. The VaproShield Mass Timber Building Enclosure Design Guideline covers the best practices for the design and construction of high-performance CLT wall and roof assemblies. RDH is the principal author and editor of the guide and within its capacity, we do not purport to endorse any specific material or technical matter within this guide.

Summary
The next generation of heavy timber building systems is about to transform the design and construction of many buildings in Australia. Products that make up heavy timber construction include: Cross-laminated timber (CLT) Expan: post-stressed frames and box beams Glulam and LVL beams, planks and floor systems An engineered timber building product, CLT is widely used internationally, particularly in Europe. Although it is not currently widely used in Australia, the potential for its specification in dividing walls, floors and ceilings is increasingly evident, particularly for multi-storey residential buildings. These buildings have acoustic requirements, stipulated in Australia by the National Construction Code, Building Code of Australia (BCA) or by a relevant Local Government Authority. Previous acoustic research programs covering CLT have been conducted in Europe and North America. The applicability of this data to the Australian market is limited due to the design of the testing to address codes that are not relevant to Australia. The overseas test elements also often include construction materials that are not available or not in widespread use here.

This state-of-the-art report has been prepared within COST Action FP1402 Basis of structural timber design from research to standards, Working Group 3 Connections. The Action was established to create an expert network that is able to develop and establish the specific information needed for standardization committee decisions. Its main objective is to overcome the gap between broadly available scientific results and the specific information needed by standardization committees. This necessitates an expert network that links practice with research, i.e. technological developments with scientific background. COST presents the ideal basis to foster this type of joint effort. Chapter 8 Connections presents an integral part of Eurocode 5 and is in need of revision. This state-of-the-art report shall provide code writers with background information necessary for the development of the so-called Second Generation of the Eurocodes, now aimed to be produced in 2022.

Summary
Mass Timber / Design and Research presents new research and design work with Mass Timber, a new construction technology, well-known in Europe, but relatively unfamiliar in the United States. Leading the Mass Timber design dialogue in the US, the author, Susan Jones, an architect in Seattle, Washington, has been pioneering the new, innovative use of wood over the past six years, since she built her own family’s house from cross-laminated timber in 2015 in a neighborhood in Seattle. The book presents her Seattle firm, her family, and her University of Washington students’ years of research and design. Opening with the story of three generations of her family’s own sustainable forest practices, the book presents research into Pacific Northwest forestry, timber and Cross-Laminated Timber manufacturing practices, to carbon analysis and carbon comparisons between standard building construction assemblies and technologies; and concludes with the design of model buildings both designed and built by her firm, atelierjones and her University of Washington students: including a single-family house, a church, schools, multi-family housing, and a twelve-story Tall Timber Wood Innovation tower on the University of Washington campus in Seattle.

Summary
The report describes a new structural system in wood that is the first significant challenger to concrete and steel structures since their inception in tall building design more than a century ago. The introduction of these ideas is fundamentally driven by the need to find safe, carbon-neutral and sustainable alternatives to the incumbent structural materials of the urban world. The market for these ideas is quite simply enormous. The proposed solutions have significant capacity to revolutionize the building industry to address the major challenges of climate change, urbanization, sustainable development and world housing needs.
