ABSTRACT: This paper describes a case study presenting geotechnical aspects of wharf construction with a marine dock as part of developing nickel-copper-cobalt ore processing facilities at Voisey’s Bay mine site in 2004. The face of the wharf foundation is constructed using four AS 500 circular cells joined together with six arcs, which also act as a retaining structure for backfill materials. The very soft clay deposit at the sea bottom within the cellular cells and connecting arcs were not dredged, necessitating instrumentation and wharf construction monitoring. The paper summarizes the subsurface conditions in the proposed wharf area based on numerous boreholes drilled. Details of the instrumentation program consisting of inclinometers, earth pressure cells, piezometers, and strain gages are presented. The data from the instrumentation obtained during construction and post-construction demonstrates the successful application of the observational approach for constructing the wharf structure in challenging subsurface conditions coupled with a short construction season.
