This case study outlines the evaluation of load transfer from a monopole foundation to an earth retention structure (three pile diameters away) and a deep utility (one pile diameter away). In the absence of as-built detail for the existing infrastructure, two design approaches were considered. Initially, a cautious estimate of the anticipated load transfer on each structure was evaluated using a combination of computer modelling and simplified analysis. In the second approach, load transfer within the influence of the existing infrastructure was eliminated with a double casing design approach. The end result was the successful completion of a pile foundation that mitigated risk stemming from unknown design and construction details of surrounding infrastructure. The case study also provides insight on the lessons learned that could be incorporated into future projects.
