EMPIRE ENGINEERING & TESTING INC . P.O. Box 776 Telephone Vero Beach, Florida 32961 305-5690153 Proposed Park , Oslo Rd . & 20th Ave'. , Vera Beach , Florida March 160 1987 PURPOSE The purpose of this investigation teras : ( 1 ) to make . soil borings in the area for determining the safe allowable bearing capacity of the soil ( 2 ) to obtain samples of the materials found beneath the proposed structure for acquiring the necessary information needed for their classification according to the Unified Soils Classification System ( U . S . C . S . ) ; and ( 3 ) to make evaluations based on the results of this investigation , consistent with good engineering practices . PROCEDURE The test holes were located at strategic points on the site . The holes were drilled with a combined Jetting and chopping action , using indus- gel drilling mud to prevent the walls of the hole from caving . At regular intervals and/or strata changes , the drilling tools were removed and the material sampled by a 1 . 5 inch I . D . , 2 inch O . D . standard split spoon sampler , driven with a 140 pound hammer falling 30 inches . The standard penetration resistance of the soil ( ASTM D1586- 64T ) was determined by the number of hammer blows required to drive the sampler one ( 1 ) foot . The records of the materials encountered and the penetration resistances are shown graphically on the attached logs. FIELD INVESTIGATION There were five (ar ) test holes made an the site . The ground water table ( GVT ) was allowed to stabilize and the depth of the ground water elevation recorded ( see soil boring logs ) . Also , while at the site , samples of the existing material were obtained and analyzed to aid in their classification according to the U . S . C . S . GENERAL . SOIL PROFILE Please refer to the soil boring logs for specific information relative to the soil descriptions . - i
