The design software, GeoStat, allows for statistical methods to be leveraged by practicing engineers in a robust manner and also facilitates estimations of pile/shaft axial resistance quantities, variability, and uncertainty. The program accepts a collection of borings/corings pertinent to a site of interest, performs both spatial variability analysis and method error estimation and permits generation of location-specific output such as through-depth resistance profiles and associated resistance factors. Foundation design data generated in this manner also overcome significant simplifications typical of current practice, where phenomena such as rock layering and area zones (i.e., spatial variability) are either ignored or indirectly accounted for via significantly more conservative (and more costly) configurations. By incorporating this type of software into the design process, quantitative indicators of scope and sufficiency will become available for budgeting, and conducting, geotechnical investigations.
