DElpending on this test result, the previous recommendations may have to be modified. TESTING AND MONITORING Construction monitoring and testing are essential to proper site construction and performance. Gompliance with the recommended construction specification for compaction and soil types must be verified by our engineering technician familiar with the project construction. Observation of site I>reparation work is an integral part of the engineering recommenclations contained in this report, Density tests should be performed for each lift of structural fill placed and per Pasco County Specifications. LIMITATIONS This report has been prepared for the exclusive use of Willingham Architecture, PA for the specific application to the project previously discussed. Our conclusions and recommendations have been Irendered using generally accepted standards of geotechnical enginee.ring geology practice in the state iOf Florida. No other warranty is expressed or implied. Our conclusions and recommendations are based on the design information furnished to us, the data obtained from the previously described subsurface exploration, and our experience. They do not reflect variations in the subsurface conditions that are likely to exist in the region of our borings and in unexplored areas of the site. These variations are due to the inherent variability of the subsurface conditions in this geologic region. Should variations become appamnt during construction, it will be necessary to re-evaluate our conclusions and recommendations bas.~d upon our on-site observations of the conditions. The site is underlain by limestone bedrock that is susceptible to dissolution and the subsequent development of karst features such as voids and sinkholes in the natut"al soil overburden. Construction in a sinkhole prone area is therefore accompanied by some risk that internal soil erosion and ground subsidence could affect new structures in the future. It is not possible to investigate or design to completely eliminate the possibility of future sinkhole related problems. In any event, the Owner must understand and accept this risk. The scope of our services does not include any environmental assefisments or investigations for the possible presence of hazardous or toxic materials in the soil, groundwater or surface water within or in the general vicinity of the site studied. Any statements made in this mport or shown on the test boring logs regarding unusual subsurface conditions and/or composition. odor, staining. origin or other characteristics of the surface and/or subsurface materials are strictly for the information of our client and mayor may not be indicative of an environmental problem, If changes are made in the overall design or the location of the proposed facilities, or if the finish grades differ from those discussed herein, the recommendations presented in this report must not be considered valid unless the changes are reviewed by our firm and recommendations modified or verified in writing, We should be given the opportunity to review the fc)undation plan. grading plan and the applicable portions of the project specifications when the design is finalized. This review will allow us to check whether these documents are consistent with the intent of our recommendations.
