Currently, no model is available that incorporates the spatial variability of soil properties into the design and analysis of pile foundations. Furthermore, only basic rules-of-thumb are available to assist in determining the scope of appropriate site investigations for piles, and limited data are available for the LRFD of piles. The new and unique finite element model, site investigation guidelines and load resistance factors will reduce the over-design and uncertainty associated with pile design, which will lead to more reliable pile foundations and reduced construction cost overruns and delays. Conservatively, it is estimated that this research will result in savings in excess of $10 million per year, in Australia alone.

目前，没有模型可用于将土壤特性的空间变异性纳入桩基的设计和分析。 此外，只有基本的经验法则可用于帮助确定桩的适当现场勘测范围，并且可用于桩的LRFD的数据有限。 新的和独特的有限元模型，现场调查指南和负载阻力系数将减少与桩设计相关的过度设计和不确定性，这将导致更可靠的桩基础和减少建筑成本超支和延误。 据保守估计，仅在澳大利亚，这项研究每年就将节省超过1 000万美元。
