The United States military is constantly evolving into an organization equipped by the latest technology and seeking the greatest protection per cost ratio for its members in harm’s way. While new protection methods are steadily produced by the Engineering Research and Development Command, most protective structure options fall into either very expensive or very labor-intensive structures with widely varying degrees of reusability and transportability. Furthermore, there is currently no widely accepted quantitative approach to help the decision-making process when choosing which system to use in a specific condition. This study will seek to create a framework which can be used to aid the decision-making process based on quantitative calculation of cost benefit of various protective systems. The framework will encompass resource metrics of man-hours, machine hours, and monetary cost. The calculations and assessments will also be affected by quantitative evaluations of military situations which can increase or decrease each value of resource metric. This study will also investigate the potential of using a mass timber product, namely Cross Laminated Timber (CLT) panels, as a protective structure that may be useful in certain military situations. While not designed to replace other systems, it is another option for military commanders and staffs to consider when choosing the most efficient and economical protection method for their soldiers.

The goal of this project is to accelerate the application of structural mass timber, such as cross-laminated timber (CLT), in outpatient healthcare construction. In particular, this project will address concerns related to hygienic and moisture performance of CLT, as well as exploring other challenges faced in mass timber construction. The project will engage with industry partners representing architecture, engineering, and construction (AEC), healthcare professionals, and policy-makers to advance the state of knowledge and market penetration of CLT in healthcare. Healthcare construction is a large and growing sector; pioneering the use of CLT in this market would significantly increase utilization of small-diameter and lower-quality timber. Ultimately, successful implementation of this project would help achieve USFS regional priorities of supporting ecosystem restoration and wildland fire management, as well as Oregon’s State Forest Action Plan goals of protecting communities at risk of wildfire, maintaining the forestland base, and preserving diversity of upland habitats.
The larger intention of this research and the future research trajectory is to expand the conception of wood as a structural building material, encouraging its broader use both within Canada and in emerging markets. When architects and engineers desire a...
Palm trees are a family of plants with hundreds of species. Most important species are coconut palm, oil palm and date palm. Most palms grow in tropical regions, but some species also in semidry regions (date palms). Palms have played an important role for the supply of food and they provide shade for agricultural crops and they are planted in parks and gardens. With exception for coconut wood, the wood from palm trees has not been used to a large extent. But it is considered as an important resource. According to FAO, coco-, oil- and date palms cover over 30 million ha worldwide with a total stem wood potential of 150-200 million m³ per year. Generally this wood resource can play an important role in the regional/worldwide wood supply; mainly in Asia, Arabic countries, Africa and Latin America. The stem of the tree (coconut-, oil- and date Palm) is between 10 and 20 (25) m long, has a lower diameter of 40 – 60 cm and a taper of 0.3 – 0.7 cm/m. Being monocotyledons, palms show distinct differences in the wood structure compared to common wood species.
Across B.C. and Canada, communities are under pressure to create better-performing buildings that meet stringent code requirements while reducing construction waste. Meanwhile, consumers are demanding high-quality structures that are delivered quickly and at a reasonable price. Modern methods of construction that include prefabrication can help construction professionals create buildings that meet all these criteria.
Furthermore, prefabrication provides steady employment and is good for the economy. The market opportunities are present across Canada and in the U.S., but prefabrication is not being used to its potential due to several barriers:
Negative perception of quality
Fear of innovation
Lack of information and understanding
Unclear economic benefits
Limited industry capacity
Planning and regulatory complications
A concerted effort to address these barriers includes:
Improving products through research and development
Researching, documenting, and promoting best practices
Developing guidance documents so prefabrication is easier to incorporate
Providing national-level leadership and resources to promote innovation
Successfully implementing these recommendations will require a broad and deep national perspective, an understanding of all stages and aspects of wood construction, and the vision and skills to bring together diverse experts and stakeholders.

In the development of an architectural concept, the perception of the client is a key element for acceptability. Wood often becomes a dominant architectural element. While decision-making on the choice of materials is often subject to budgetary considerations, it appears that the added value of wood in the building’s design, even on the basis of preliminary sketches and models (physical or visual), is not adequately delivered. The project proposes to explore augmented reality technology as a technique allowing greater acceptability of wood material during the initial design phases. The architectural component will explore the creative potential and quantify public perception when subject to the use of wood material in augmented reality.
