We also probed sinular locations and were able to verify that the majority of diose <br /> Iocations were very similar in moisture content to what the Private Eye report had reported. <br /> The areas of significant moisture indicated in their report seemed to foilow son�e of joist band areas above <br /> the garage and around the front entry of the home,where it stopped. In addition,there was a significant <br /> amount of moisture indicated at the areas where the downspouts were located. These also seemed to be <br /> interior corners where the changes in the sheet metal coping also existed. Tlie �u-ched areas on the rotunda <br /> at the lower level also indicate high temperature locations centered in the space between the arches. This <br /> appears to follow the rectangular forni of the underIying wood stud structure, which will be denser and hold <br /> the heat longer than the adjacent simple stucca areas. There are a number of indications below windows <br /> such as the radius around the kitchen and the floor below where potential moisture may be present. <br /> Observations <br /> On August 29, 2006,Doug Lawson and Steve Flaten visited the site to review in more detail die <br /> installations and take test cuts in the exterior stucco. These test cuts were going to be to verify actual <br /> conditions presumed to be wet based upon some of tI�e testing from the infrared and moisture probes and <br /> validated by our moisture probe. Six cuts were made on the home to determine the assemblies and the <br /> moisture contents underlying. The following is an outline of the tests that were rnade: <br /> Test Cut Number 1 <br /> Located under the kitchen window, between the first and second units in the radius wall area. In this <br /> location we found no rust on the underlying reinforcing mesh. There were two layers of nun�ber 15 <br /> building paper installed and the moisture content read through the building paper was between 9 and 10 <br /> 1/2 percent. There was a building paper membrane tucked underneath the window flange and a casing <br /> bead was used adjacent to the windowsill as this�vas on a radius and the windowsill was squared into a <br /> tangential line. <br /> Test Cut Number 2 <br /> This cut was located in the column area of the porch,between two archways facing the lake side. When <br /> this area was cut open we found two layers of number 15 building paper and moisture content of the <br /> underling plywood was 14 percent. The wood was solid and undamabed. <br /> Test Cut Number 3 <br /> This cut was Iocated at the joist band on the porch area above test cut number 2. This was selected as it <br /> was directly below the intersection of the paving area and the column intersection to see if there was any <br /> potential for water entry. At this location we identified moisture content between 20 and 24 percent. <br /> There were two layers of number 15 building paper installed in this location. It does not appear there was <br /> any damage to the wood at this point. <br /> Test Cut Number 4 <br /> This test was located at the east side of the family room area at the tower level. This was located at the <br /> center mullion between rivo of the casement windows and over the flange where the windows met. At <br /> this location,we identified that water was present on top and behind the building paper. There was no <br /> sealant provided between the bottom of the window and the top layer of building paper ran over the top of <br /> the flange for the window. The building paper was cut in the center of the opening and pulled up to <br /> reveal 2 layers of building paper. The paper was then split vertically underneath the mullion. At this <br /> point,we identified the building paper was aver the top of the flange. There was no sealant below the <br /> window flange and without sealant around the window perimeter there was potential for water to run <br /> behind the paper at this point as well and water to get into the parting line between the two fixed <br />
