Abstract: NIT Srinagar was requested to carry out Non-destructive test of civil work of Gulmarg Gondola Project (cable car project) at Gulmarg (J&K) under J&K State Cable Car Corporation. So as to assess the present strength of R.C.C. columns of project the non-destructive testing of various columns along with condition survey was carried out to assess integrity of structural members. Investigation was carried out to check the concrete quality, corrosion in reinforcing bars and carbonation of concrete. The concrete quality was found out by using Ultrasonic technique and Hammer Rebound method. The carbonation was determined by use of Phenolphthalein test. The visual examination was carried to find out (locate) the dampness, cracks and other defects in the buildings. The purpose of the survey is to collect sufficient data to pinpoint the cause and source of the problem and to determine the extent of the damage. Durability of concrete is a function of the performance of concrete with respect to time in the service conditions. The concrete is said to be durable when it can withstand the conditions, for which it is designed, over a period of time without getting damaged or deteriorated. Protected concrete has shown more resistance against carbonation and chloride ingress when compared to unprotected concrete. It is myth to believe that concrete is a maintenance free construction material if subjected to different exposure conditions and durability is an actually a function of water entry in concrete. The objective of the investigation is to test the structural integrity of various RCC members by assessing the deterioration with respect to quality and strength of concrete, permeability, corrosion, cracks and other defects causing distress.
