Nationwide Insuranc8 - Center for Radiation Oncology, 7315 Green Slope Drive, Zephyrhills, FL Lab No. 190442 Page 2 . Perform hand auger borings around the perimeter of the structure to better characterize the shallow soil conditions and to identify any deleterious materials such as buried debris, organic soils, or expansive clays that may be present. . Perform static cone penetrometer tests around the perimeter of the structure to better characterize the penetration resistance of the shallow soils encountered. . Conduct test pit excavations to determine the type of foundation, to measure its dimensions and the depth of embedment. . Perform four (4) standard penetration test (SPT) borings to determine the stability of the soil profile relative to the possible presence of sinkhole activity. . Issue a report of our findings including our opinion as to the cause(s) of the damage to the building. Previous Work A copy of a previously completed engineering report was furnished to our office for review. Bracken Engineering, Inc. completed a report of findings titled "Limited Structure Condition Assessment: Center for Radiation Oncology" at the subject property for Nationwide Insurance in February 2007 (File No. 307-007) that summarized the their limited structure condition assessment and presented an opinion as to the cause of damage to the building. The Bracken Limited Structure Condition Assessment consisted of a cursory, non-destructive visual evaluation with observations documented with photographs. It was the opinion of Bracken Engineering, based on their observations, that the interior wall damages and the water intrusion observed and reported was directly attributable to the stucco control joint deficiencies; that the lack of a protective coating atop the steel control joint served to promote degradation of the steel and subsequent delamination of the stucco, thus promoting water intrusion to the interstitial wall cavities; that the pronounced crack within the foyer floor slab was the result of a shrinkage crack aggravated by differential movement of the structure; that while the cause of the damage was found to be soil displacement, the full cause and extent of the soil displacement remains unidentified. Bracken Engineering recommended that a geotechnical engineer be consulted so as to identify any subsurface anomalies and to develop a subsurface remedial plan to arrest any further differential displacements as deemed necessary. Site Description and Inspection The subject structure is a one story, slab on grade, masonry structure located in southeastern Pasco County in Zephyrhills, Florida.
