This paper deals with the special technique adopted for well foundation construction in maritime environment by creating an island using steel liner and sheet pile cofferdam. By adopting this technique, conventional method of constructing well foundation using steel caissons was eliminated. This technique of well foundation construction provided quantum reduction in steel quantities as well as construction time. This paper gives an insight to design and construction technique adopted for well foundation construction of long span steel bridge Package CTP 15B across river Narmada, Gujarat using sheet pile and steel liner cofferdam.
