Abstract

Redevelopment of the eastern section of the Viaduct Basin in downtown Auckland, New Zealand, provided the stopover base for the 1993/1994 Whitbread Race. This required the construction of a new quay structure, dredging and a reclamation. An intregal part of the whole project was the use dredged marine mud for the reclamation. To gain strength and to minimise leaching of the contaminants, the marine mud was stabilised with ordinary Portland cement to become known as mudcrete. This paper discusses the design methodology for the sizing of the structural elements in the quay wall and outlines the benefits of using mudcrete. The paper also outlines investigations undertaken to assess the effects of leachate released from the reclamation to the natural environment. Finally, the paper compares measured strengths and water quality pa
