110

Duxbury is now classified in the 110 mph wind zone for building  purposes.  This means that all buildings have to be built to resist wind uplift, shear and overturning loads associated with this type of wind.  Within one mile of the water all windows need to be made of high impact glass or have ready- made plywood covers available in case a storm is coming.    The added expense incurred has been a damper on new building in our area in a time when building activity is already severely depressed.   Some buildings and configurations of buildings can no longer be built, although a provision is made if an engineer stamps the plans to certify that the proposed building will have sufficient wind resistance.  There are also requirements for shear walls to be integral with new structures and for the shear walls to be incapable of being turned over by the wind.   For one and two story buildings in relatively sheltered locations the amount of effort that goes into tying them to the ground defies common sense.  The manual is at the American Wood Council website  http://www.awc.org/pdf/WFCM_110-B-Guide.pdf

We recently submitted an application for a building permit for a project within the one mile zone from the water.      We had to specify the types of hold down connections from four feet under the ground to the top of the roof.   It will take several applications and jobs done to the high wind specifications for us to learn exactly what the code requires and what each local inspector is going to emphasize.

Wood, Stone and Steel

I was looking at old tools in an antique shop in Wells Maine last Saturday.  There were stacks of beading planes and rabbet planes all made of a maple block with a forged and filed steel blade wedged tightly into the mouth by a separate piece of maple, there were chisels and spoke shaves, adzes, drawknives.  There was a cooper’s plane that was curved to the inner radius of a  barrel.  The carpenter’s trade once involved much more direct contact with basic earthly elements; hand to simple machine to the work.
