The NDCT is designed in detail as per tender stipulation after post award stage to find the variation in quantity due to modified technical conditions. The variation in quantity has been evaluated for all the elements and design, drawings and BOQ have been prepared. The total saving in concrete is worked out 5% and for reinforcement 8% despite the fact that raker piles were considered in tender condition vis-à-vis vertical piles in revised design. This significant saving has helped our client to settle extra claim on account of additional provisions in post bid design stage.
