The event is being organized by the Pennsylvania Horticultural Society. The workshop is intended to bring together suppliers, processors, and end users of urban wood who recognize the value of the resource and wish to make better use of the material. The workshop serves as a first step toward developing an urban wood network in southeast Pennsylvania to link potential partners.
An advisory committee will be formed as a result of the initial meeting, and will help guide the DCNR Bureau of Forestry in moving the process forward. The targeted audience includes arborists, tree services, municipal public works offices, portable and stationary sawmill owners, dry kiln operators, craftspeople, artists, architects, and educators. Wisconsin Urban Wood is a network of independent businesses and nonprofit organizations that promotes the utilization of urban wood. As a network, WUW is instrumental in working to keep urban ash trees from simply being chipped to minimize the spread of emerald ash borer.
The group also works to connect the supply of the wood to those who can turn the logs into a valuable commodity. In addition, WUW promotes the societal environmental and economic value of urban wood to communities and property owners across Wisconsin. Green Tier is a voluntary program administered by the DNR. They are the basic building blocks for such common structures as balloon-frame or platform-frame housing. Dimensional lumber made from softwood is typically used for construction, while hardwood boards are more commonly used for making cabinets or furniture.
Lumber's nominal dimensions are larger than the actual standard dimensions of finished lumber. Historically, the nominal dimensions were the size of the green not dried , rough unfinished boards that eventually became smaller finished lumber through drying and planing to smooth the wood. Today, the standards specify the final finished dimensions and the mill cuts the logs to whatever size it needs to achieve those final dimensions.
Typically, that rough cut is smaller than the nominal dimensions because modern technology makes it possible to use the logs more efficiently. After drying and planing, it would be smaller by a nonstandard amount. As previously noted, less wood is needed to produce a given finished size than when standards called for the green lumber to be full nominal dimension. However, even the dimensions for finished lumber of a given nominal size have changed over time.
In , at a meeting in Scottsdale, Arizona, the Committee on Grade Simplification and Standardization agreed to what is now the current U. Dimensional lumber is available in green, unfinished state, and for that kind of lumber, the nominal dimensions are the actual dimensions. Individual pieces of lumber exhibit a wide range in quality and appearance with respect to knots, slope of grain, shakes and other natural characteristics.
Therefore, they vary considerably in strength, utility, and value. The move to set national standards for lumber in the United States began with publication of the American Lumber Standard in , which set specifications for lumber dimensions, grade, and moisture content; it also developed inspection and accreditation programs. These standards have changed over the years to meet the changing needs of manufacturers and distributors, with the goal of keeping lumber competitive with other construction products.
Secretary of Commerce. Design values for most species and grades of visually graded structural products are determined in accordance with ASTM standards, which consider the effect of strength reducing characteristics, load duration, safety and other influencing factors.
Canada has grading rules that maintain a standard among mills manufacturing similar woods to assure customers of uniform quality. Grades standardize the quality of lumber at different levels and are based on moisture content, size, and manufacture at the time of grading, shipping, and unloading by the buyer. Attempts to maintain lumber quality over time have been challenged by historical changes in the timber resources of the United States — from the slow-growing virgin forests common over a century ago to the fast-growing plantations now common in today's commercial forests.
Resulting declines in lumber quality have been of concern to both the lumber industry and consumers and have caused increased use of alternative construction products. Machine stress-rated and machine-evaluated lumber is readily available for end-uses where high strength is critical, such as trusses , rafters , laminating stock, I-beams and web joints. Machine grading measures a characteristic such as stiffness or density that correlates with the structural properties of interest, such as bending strength.
The result is a more precise understanding of the strength of each piece of lumber than is possible with visually graded lumber, which allows designers to use full-design strength and avoid overbuilding. In Europe, strength grading of rectangular sawn timber both softwood and hardwood is done according to EN  and commonly sorted into classes defined by EN For softwoods the common classes are in increasing strength C16, C18, C24 and C There are also classes specifically for hardwoods and those in most common use in increasing strength are D24, D30, D40, D50, D60 and D For these classes, the number refers to the required 5th percentile bending strength in Newtons per square millimetre.
There are other strength classes, including T-classes based on tension intended for use in glulam. In North America, market practices for dimensional lumber made from hardwoods [a] varies significantly from the regularized standardized ' dimension lumber ' sizes used for sales and specification of softwoods — hardwood boards are often sold totally rough cut, [b] or machine planed only on the two broader face sides.
