From the Dynamic Assay, 10 precast piles in metallic profile of a 28-storey commercial building in the city of Belém/PA were analyzed, executed in soil, consisting mostly of sandy clay and silty sand. This study has as methodology the analysis of the geotechnical investigation of the studied area through the Standard Penetration Test; load transfer analysis; methods for predicting load capacity and settlement in driven steel piles, where the executive process and method and control were described.

From the Dynamic Assay, 10 precast piles in metallic profile of a 28-storey commercial building in the city of Belém/PA were analyzed, executed in soil, consisting mostly of sandy clay and silty sand. This study has as methodology the analysis of the geotechnical investigation of the studied area through the Standard Penetration Test; load transfer analysis; methods for predicting load capacity and settlement in driven steel piles, where the executive process and method and control were described. The concept, preparation and obtaining of dynamic test results (the study of the wave equation, Smith model, CASE and CAPWAP method). From the results, the graphs of mobilized force versus displacement were analyzed. The results obtained in the dynamic tests were compared with the design static load capacity obtained by the semi-empirical Aoki-Veloso and Decourt-Quaresma load capacity prediction methods. The values obtained in the tests reached satisfactory levels close to the values calculated by the semi-empirical methods, proportionally to the length of the tested piles.
