Abstract
Foundation materials of Karachi urban areas were sampled from different towns developed on Gaj Formation of Miocene age which is mainly composed of argillaceous limestone alternating with shales and clays of variable thicknesses. During collection of samples of foundation materials from different towns, special consideration was given to the geomorphic features developed in the towns. Geomorphological features investigated have been divided into seven zones to determine the possible impacts of these features on the textural characteristics and other geotechnical properties like bulk density and bearing capacity of the foundation materials. The evaluation of the data estimated for textural characteristics, average bulk density and the bearing capacity of foundation materials have been presented with the help of graphs prepared for the fifteen towns and a newly developed Defence Housing Authority have been described. The geotechnical characteristics of the foundation materials determined would be of great assistance in foundation designing of huge civil structures in different parts of Karachi urban area.
