  • ISSN : 1021-2019



The construction phase of the piled foundations for the Alusaf Hillside Smelter required extensive quality control measures to ensure full compliance with the demanding specifications of the project is a founding environment characterized by highly variable and often adverse subsurface conditions. A carefully planned programme of load testing of special trial piles, proof load testing of working piles and integrity testing of working piles using the impulse frequency response method and the sonic logging method was successful in achieving a level of quality control comparable with the best international standards.
