Non-Destructive Testing of Drilled Foundations at Cove Point using Thermal Integrity Profiling
The Dominion Cove Point LNG Terminal, located in Lusby, Maryland, recently began a $3.8 billion-dollar terminal upgrade to expand capacity and facilitate export capabilities. Given the soil conditions, strict vibration thresholds, and site logistics at the active LNG facility, Dominion and the IHI-Kiewit Cove Point JV selected drilled, cast-in-place elements as the primary foundation type to support temporary/permanent structures. Over 4,750 Auger cast-in-place piles and 700 drilled shafts were installed. Due to the sensitivity of the proposed structures, extensive non-destructive integrity testing (NDT) was required. The initial quality control program included pile echo testing and cross-hole sonic logging (CSL). However, due to site specific limitations, alternative NDT methods were required. Thermal integrity profiling was ultimately selected and the results of large-scale testing highlight this new technology as a highly effective and cost-efficient method of testing drilled, cast-in-place foundations.
