Drilled shafts are widely used in Dubai as the primary foundation option for high-rise towers and bridges. Hundreds of meters of drilled shafts are installed in Dubai daily. The piling industry has grown significantly in Dubai over the past two decades. Piles with large diameters up to 2.5 m and lengths reaching 100 m are common. Current practice for geotechnical axial load capacity estimation is generally conservative, with actual pile axial load capacities demonstrated by static and dynamic loading tests often substantially higher than theoretical design capacities in most cases. The main objectives of this study are to review the shortcomings of commonly used theoretical axial load estimation procedures, examine the factors and parameters controlling estimated axial capacity (input parameters), and suggest optimization of conservative design procedures through careful selection of key input parameters and calibration to static loading tests.
