Details: conducting ultra sonic pulse velocities tests, at all locations prepared after chipping the plaster, on columns, beams and portal frames to assess the integrity of concrete as per bis/astm specifications etc. complete. conducting rebound hammer test as per bis/astm standards etc. complete. conducting half-cell potential meter test at all locations to assess the risk of corrosion including exposing the reinforcement for carrying out the test. the test shall be conducted as per bis/astm specifications. the quoted rate shall include charges for filling back areas chipped for exposing the reinforcement with polymer modified mortar. 5 potential observations taken at one location will form a unit for measurement purposes. extraction and testing of concrete drill dust samples from the structure. three drill dust samples from depths 0-15mm, 15-30mm and 30-45mm shall be collected from each location. the samples shall be tested for chlorides, sulphates, ph and alkalinity. conducting carbonation
