September 4 , 1998 <br /> page Two <br /> Near the top of the pedestal construction there should be two <br /> horizontal dowelled connections into the corner of the foundation. <br /> The depth of holes for the dowels should be approximately 6"- <br /> Additionally, we recommend the pedestal be reinforced .in the center <br /> with a *4 steel reinforcement bar. All dowelled connections and the <br /> steel reinforcement shall be provided with a minimum of 1 1/2" of <br /> concrete cover in the construction. A pinned connection should be <br /> provided between the wooden column and the pedestal as previously <br /> described in our report of August 24 , 1993 . <br /> The extension of the brick masonry construction for the column <br /> support must be isolated from the replacement, construction of the <br /> concrete stoop. The isolation joint construction between the brick <br /> masonry and the stoop should be sealed with a high grade ,point <br /> sealant to prevent moisture migration into the joint construction. <br /> The structural distress in the existing stoop most likely was the <br /> result of moisture absorbed by the wooden column which caused <br /> swelling of the wood. The swelling resulted in tension failure in <br /> the surrounding concrete . <br /> Respectfully, <br /> Professional EEigineerin consultants , Inc . <br /> J n F.
