Subsidence Invr;stigation SDII Project Number:3023547 Quiros-Martin��z Residence-Zephyrhills, Florida photographs ,.ind other information obtained by SDII will be retained in the project file and can be provided u.pon request. On the interior of the residence, SDlI observed cracks in the walls of the utility area. There were cracks in the:Eloor tiles of the living room. A crack was noted in the grout joint between the floor tile and the ba.thtub in the northwest bathroom. There was separation between the doorframe and the ceiling in the kitchen. There were also cracks in the grout joint between the wall tiles in the shower of the northwest bathroom. On the exteric:�r, SDII noted cracks in the northeast and northwest wall elevations. There was a crack in the i loor tile of the front porch. There were also cracks in the concrete slab of the driveway. 3.4 Relati��e Floor Elevation Contour Map The data for a relative floor elevation contot�r map was collected on May 14,2010. The methods used to evaluate the floor configuration are described in Appendix A. Figure 5 depicts the contour map stzowing the relative elevations of the floors. Where carpeting, wood, tile, or other floor coverings exist, corrections have been made to obtain the top of slab elevations. The floor elev,ation map indicated that there was a total elevation difference of approximately 1.2 inches across the floor slab of the main living area of the residence. The highest elevation was recorded at tL:e south portion of the floor stab, and the floor elevations generally decreased toward the no7�theast wall of the residence. The pattern of elevation change of the floor slab of the residence is consistent with minor differential foundation movement. The floor slab of the converted garage was constructed 4.0 inches below the finished floor elevation (FFF;) of the living area. The floor elevations in the converted garage have been adjusted to reflect this difference. The floor slab of the garage exhibited a slope of approximately 1.2 inches over a span of 25 feet descending toward the south corner of the garage. It should be noted that the:Eloor slab of a garage would normally be sloped toward the garage door opening to altow proper drainage. Therefore, given that the garage floor does not slope toward the door opening and t�iere is damage present in the garage, it is SDII's opinion that the garage has experienced minor differential foundation movement. 3.5 Evalua tion of Observed Damage The interior s:;parations and cracking observed on the structure is consistent with structural movement tha�r is within a reasonable range for the type and age of construction and the soil types and co,nditions encountered at the site. This structural movement includes minor differential fou.ndation movement, ]ong-term deflection of primarily wood framing members that occurs over t.he life of the structure, and post-construction settlement. Minor differential f'oundation mo�vement typicalIy affects interior and exterior walls and floor level. Long-term deflection typic;ally involves roof/ceiling framing members and affects ceiling finishes. Post- construction structural settlement occurs when the self-weight of a structure and building components is transferred to the design beanng locations. The remaining stress will be 3-2
