Trees is among the oldest of mans development fabrics, yet as the development scene at the present time is ruled through concrete and metal, many designers are strange with the houses of bushes and its structural vocabulary.
This new ebook starts with a longer advent to bushes as a construction fabric: its a variety of varieties and homes, its reaction to environmental stipulations, and the development rules with regards to its use. It is going directly to keep on with the overall series of labor, beginning with the fee, after which facing the survey, the research and the appraisal

For preservation to be eective, therefore, it must be applied to the pro®led member. Hazard class 4: ground contact, is the most severe hazard class. Fence posts always fail at ground levelÐabove, the post is too dry, and below ground too wet. The transition zone will inevitably produce at some point the optimum moisture content for the development of rot. Timber properties and preservative treatments for the design of timber in dierent building locations are given in BS 5268: Part 5 for structural work and in BS 5589 for non-structural work.
