43 of 49 Construction of Giresun Wastewater Treatment Plant  Tender Dossier Volume 3 Employer’s Requirements  Section 05: Earth Works, Pipe Works and Ground Improvement   pile structural integrity; extent and location of damage   maximum energy transferred to the pile   blows per minute for hammer check   blow number   input and reflection of force, velocity, upward and downward force waves   load versus deflection of cushions and of pile toe bearing   deformation properties, ultimate capacities and soil damping parameters for each soil segment  of normally 1 m length   unit skin friction for each segment and end bearing   maximum of tension and compression forces and stresses   pile structural damping   dynamic pile toe displacement   graph on bearing capacity and pile stresses versus blow count  CAPWAP or similar programs determines that set for soil resistance parameters which produces the  best match between measured and computed pile top force and velocity. After CAPWAP analysis ad- ditional information than above for CASE is accomplished as:  An introductory program (WEAP) can be utilised before pile driving to assess preliminary combina- tions of sets and bearing capacities for specified pile, driving equipment and soil conditions.  The data processing shall be carried out by well experienced experts.  The piles to be tested are selected as in 5.4.6.14. The Contractor shall notify the Engineer at least two weeks prior to dynamic testing.  The Contractor shall submit a qualified testing Consultant and his experience to the Engineer for ap- proval.  The Engineer shall determine if the test is to be performed or if some pile waiting periods at the pro- posed site is required before a decision will be made.  b) Dynamic Load Test Procedure  The Engineer will establish a date for the tests and will also determine the location of all piles to be  dynamically load tested.  c) Dynamic Load Test Procedure on Driven Piles  The Contractor shall supply all personnel and equipment needed to strike the test pile with the ham- mer.  The Contractor shall provide the hammer (drop, diesel, etc.) or the mobile crane to lift a steel ram  weight by a single non-twisting cable and be able to strike to the pile top by mean of full-gravity-fail.  The instrument for the dynamic load test shall conform to ASTM D 4945.  Approximately two driven piles will be tested in one day. The testing Consultant personnel will drill  holes into the pile to be tested so that transducers (two accelerometers and two strain gauges) can be  attached. Testing procedures shall be conformed to ASTM D 4945.  When the transducers have been placed in position and the recording and processing equipment has  been made ready to receive the acceleration and strain measurements, the Engineer will instruct the
