The quality of construction work on the actual site has to be controlled and maintained. For this purpose sample of construction materials are taken to examine and verify different quality aspects. The method adopted for this task is termed as ‘Sampling Technique’. The sampling technique gives the procedure, intensity and methods of sampling as per the given programmers. Samples are collected and properly tested. The results obtained in testing are compared with the standard specifications.
