Bored cast-in-situ RC pile technology is the most popular deep foundation construction method, which introduced in the country, by few foreign companies, since mid fifties of last century. Unfortunately, no significant advancement have been accomplished to improve quality, rather than acquire few hydraulic powered rotary boring rig by general contractors in last three to four years. Introduction of such sophisticated hydraulic rigs is definitely a forward step but
machines by themselves do not ensure good quality. We are Emphasising on the construction technique that may ensure quality of bored pile as well as the economy.
