In 1971 "Micro=Lam LVL" was introduced. "Micro=Lam LVL" consisted of laminated veneer lumber billets 4 feet (1.2 m) wide, 3 + 1 ⁄ 2 inches (89 mm) thick, and 80 feet (24 m) long. Troutner proved the structural capabilities of his Micro=Lam product by building a house in Hagerman, Idaho, using beams made of Micro=Lam.
For every 100 females, there were 96.3 males. For every 100 females age 18 and over, there were 95.1 males. There were 593 housing units at an average density of 178.4 per square mile (68.9/km 2), of which 520 (93.2%) were owner-occupied, and 38 (6.8%) were occupied by renters. The homeowner vacancy rate was 2.4%; the rental vacancy rate was 7.3%.
The span replacement took place between 2002 and 2013, and is the most expensive public works project in California history, [5] with a final price tag of $6.5 billion, a 2,500% increase from the original estimate of $250 million, which was an initial estimate for a seismic retrofit of the span, not the full span replacement ultimately completed.
In engineering, span is the distance between two adjacent structural supports (e.g., two piers) of a structural member (e.g., a beam). Span is measured in the horizontal direction either between the faces of the supports (clear span) or between the centers of the bearing surfaces (effective span): [1] A span can be closed by a solid beam or by ...
In 1961, at a meeting in Scottsdale, Arizona, the Committee on Grade Simplification and Standardization agreed to what is now the current U.S. standard: in part, the dressed size of a 1-inch (nominal) board was fixed at 3 ⁄ 4 inch; while the dressed size of 2 inch (nominal) lumber was reduced from 1 + 5 ⁄ 8 inch to the current 1 + 1 ⁄ 2 inch.
Competitive auctions determine the stumpage fees to be paid. The difference between the cost of acquisition of harvested timber between the United States and Canada is the cause of the ongoing Canada-United States softwood lumber dispute. The United States' representatives claim the Canadian system of determining stumpage fees amounts to a subsidy.
