Extremely tough geography and remote location.Over 96 piles were in defective condition with concrete etching out ,pores were there and reinforced steel was visible at 1.5 metre height .The piles were divided into minor ,medium and major defective piles to assess methodology accordingly.It was a high rain density area with many many days of continuous rains leading to water fill and soil in the pile area.This needed to be dewatered again and again before repair work was carried out
3 pronged solution was offered .First all piles were classified as minor defect,medium defect and major defect on basis of comprehensive testing using NDT ,impulse metre test,rebound hammer testing ,half cell potential test and others
We were the only company to bid for this work and completed the entire repair and rehabilitation with strengthening of damaged piles within 5 months in spite of extremely tough terrain.It was a turnkey project
