FLORIDA GEOLOGICAL SURVEY


 2. May choose to explore only those geophysical anomalies
 nearest the structure, preferably near areas of greatest
 damage with adequate justification.

 3. If no anomalies are detected or if the anomalies are distant
 from the damage identified during the initial site visit,
 locate the SPT tests in close proximity to the damaged
 portions of the structure.

 4. If sinkhole loss related geophysical anomalies or known or
 suspected sinkholes are distant, a SPT boring can be placed
 between the feature and the house in order to determine if
 the house has been affected by the processes that may have
 caused the remote feature.

 ii. Ensure that all potential subsurface causes of the damage are
 adequately characterized. Adequate characterization will include
 enough testing to reasonably confirm any subsurface causes) of
 the damage.

 iii. Site and location specific drilling equipment (truck or trailer
 mounted models, hand augers, and tripod) should be used. The
 only rationale for not drilling where the cause of the damage is
 likely to be manifested should be human health and safety or
 inability to obtain legal access. These should be documented in the
 report.

 iv. Utility location procedures should be followed to ensure the safety
 of drilling crews and others on site as well as the structure. Where
 local or state requirements exist for utilization of the services of
 utility location providers, they will be utilized. (note that utility
 location services will usually only work on public right-of-way and
 not on private property)

 v. The boring materials recovered and their depths should be
 documented and described in the drilling log. It is recommended
 that these shallow soils be tested by a calibrated manual cone
 penetrometer in order to complete documentation of the relative
 strengths of materials encountered in the boreholes.

 vi. All test holes should be backfilled or grouted in general accordance
 with applicable procedures established by the county or water
 management districts in Florida.

e. Cone penetration tests mechanical (CPT), electric CPT, piezocone
 (CPTU), seismic piezocone (SCPTU), resistivity piezocone (RCPTU) and
 horizontal stress cone (HSC). Location criteria same as for d. above.
