Summary
The objective of this project is to identify the risk factors taken into account in the pricing of an insurance contract for a construction site. This project aims to synthesize the quantitative approaches used in practice and presented in academic research for the pricing of home insurance and commercial insurance. Then, we aim to identify the preventive measures that can be taken to reduce the impact of different perils in the insurance of a construction site in wood or other.

Summary
Michigan State University (MSU) will develop a construction time and cost estimating tool for the use of cross laminated timber (CLT) in commercial building construction. This responds to a significant barrier to adopting such buildings among the architecture, engineering, and construction (AEC) industry, which has been reported since 2014. Despite broad agreement that first costs (and by extension time) and life cycle costs are an important facet of CLT buildings, over one third of architects were uncertain about this topic. Nine out of ten architects also listed costs and cost information as a significant barrier. This project will expand wood products markets by addressing this significant AEC industry barrier, and as a result, encourage more designers and constructors to specify CLT in their buildings. The project includes the development of a web-based predictive cost and time tool; this is quite common during the conceptual design stage, and as such, these tools exist for steels and concrete buildings, yet very little information exists for CLT. The team will also develop up to 20 CLT building case studies, with a focus on as-built costs, life cycle costs (building maintenance, energy, and carbon), construction time, and green building certification. These cases will be used to develop continuing education training modules for designers and constructors. Finally, in an attempt to motivate current students to become more knowledgeable about CLT, MSU will sponsor a 4- and 2-year CLT construction management competition. We expect these efforts to reach over 300 designers and constructors, and up to 75 AEC students.

Summary
To ensure the acoustic performance of wood constructions, the research group at the Sustainable Building Institute at Napier University has established a series of proven solutions. The advantage of this approach is to provide designers with solutions that have been technically validated, thus allowing them to overcome the burden of proposing to the manufacturer an acoustic solution. The tools to develop this concept will involve an understanding of the propagation of impact and airborne noises in the main CLT building design typologies, validating the main solutions through laboratory testing and providing proven solutions. Many NRC (National Research Council of Canada) trials could have been avoided. Conducting tests is expensive, and it would be interesting to link the test results to the modeling results.

Summary
Currently, only light frame wood-based shearwall and braced and moment-resisting frames are given in the NBC 2015 as acceptable solutions, with the height limit for these SFRSs in high seismic zones being 20 m (6 storeys). There is no acceptable solution for using Timber SFRS in buildings more than 20 m high in high seismic zones. The Tall Wood building projects in Canada have been following the “Alternative Solution” path with supporting test data and analysis that could demonstrate equivalent or better performance than building and fire code or local condition requirements, and were approved on a case-by-case basis by the Authority Having Jurisdiction (AHJ). The Tall Wood projects have been and will be faced with different level of difficulties and challenges depending on the familiarity of AHJ with tall wood construction. Furthermore, there are no consistent procedure and performance criteria to analyze and evaluate the Timber SFRS in tall mass timber buildings that could be referenced by the AHJ. This project is to undertake the work related to: Phase I: development of a Technical Guide with a procedure for evaluation of the seismic performance of Timber SFRS in tall mass timber buildings. Phase II: evaluation of an example solution of Mass Timber SFRS in accordance with the developed Technical Guide as a “Demo” project.

Summary
This project will generate three benchmark data sets for multistory CLT building moisture performance in different climate zones. Data will include moisture contents at key wood components and high moisture risk locations throughout the buildings. A relatively simple, but fully validated, numerical model for analyzing similar building moisture performance will be recommended. These results will be useful for structural engineers and architects to accurately consider moisture in their design of mass timber buildings.

Summary
The Nature Conservancy is leading a multi-institution collaboration to quantify the potential for innovative mass timber materials to support improved forest management, revitalize forest economies and mitigate greenhouse gas emissions. Life cycle assessments (LCAs) of engineered timber products such as glued laminated timber (glulam) and cross-laminated timber (CLT) in construction have highlighted their environmental advantages over conventional materials such as concrete and steel. However, there is little understanding of how developing new markets for such materials could support the wood product sector and the management of US forests. This applied research will assess in detail the potential impacts of large-scale growth in mass timber demand on wood product markets, timber harvest, forest management and climate change mitigation in key wood-producing regions across the USA and globally, as well as opportunities to leverage these markets to support US forest management and rural economies. The findings will be used to produce peer-reviewed publications and design a suite of targeted stakeholder engagement materials and programs, providing an objective, credible fact base to inform the design of policies and programs to maximize environmental and economic benefits of mass timber use for the forest sector.
