With the advancement in underground construction, the construction technology for deep excavation is gaining importance. Excavation support is generally required to be planned specifically when the depth of excavation exceeds 10 to 20 feet or if the excavation is not sloppy. Excavation support systems help in minimizing the excavation area and to maintain the stability of the sides of the deep excavation. Steel sheet piling is one of the earth retention system which is made up of long structural section that uses steel sheets with interlocking edges to retain earth or water. Sheet pile walls have been used to support excavations for underground parking structures, basements, pump houses, and foundations, to construct cofferdams, and to construct seawalls and bulkheads. This paper describes the cost involved in the method of steel sheet piling to support the sandy soil with different site conditions. A relationship between the cost and parameters like retention height, embedment depth, bending moment, section sizes is obtained which could help in assessing the cost implication of steel sheet piling on the project, hence helping in the forecasting cost, both for client and other building contractors.
