Abstract : Great difficulties are usually encountered in the design of pile foundations in marine strata. These difficulties have been attributed mainly to the heterogenous nature and unusual behavior of these strata. Quite commonly, the marine strata have low bulk density and usually consist of weakly cemented calcareous and carbonate soils interbedded with coral rock containing cavities filled with coral debris. Geotechnical investigations show that conventional soil mechanics techniques are not successfully applicable to these formations and sediments. This paper presents a case study of a proposed foundation design for a 380 m long quay. This quay is to be constructed near the city of Jeddah on the east coast of the Red Sea. The initial proposed design by the designer suggested 60 cm square precast concrete driven piles. This proposal was not satisfactory to the geotechnical consultant of the contractor, and instead he recommended bored and grouted piles. This recommendation was based upon field data, load testing of piles and information available in the literature. A critical evaluation of both, the proposed design as well as the alternative put forward by the contractor, is given in this paper along with recommendations envisaged by the authors.
