In recent years, land reclamation works have been extensively implemented along the coastal lines for a variety of purposes. This paper relates to the case history of a land reclamation project for a steel mill complex construction in Korea. Site improvement techniques used in this project include construction of sand drains and pre loading. Construction procedures of sand drains are described as well as staged loading process along with field observations. Field measurement of settlement and theoretically estimated values are compared. The results of standard penetration tests and unconfined compression tests at various depths of soil, and time intervals are presented. Finally, the methods of construction quality assurance are discussed
