Extent of risk management implementation in some of rock laboratorytests for tunnel projects by means of AHP method

In any project, especially infrastructure ones such as tunnels, tests play a major role in predicting andshowing the properties of the ground built on. For such construction through a rock mountain terrain, it isquite not easy to predict the engineering property of such materials. Since working with rock is a quitechallenge because of the nature of rock materials, it needs a lot of care and persuasion when dealing withsuch. For such rock materials, it needs both of field and laboratory tests to ensure the process of obtainingthe final engineering property of the materials. This paper concentrate on some of the laboratory testsrequired for tunnel project held in rock profile sites. Emphasizing on safety, accuracy that enquired duringsuch tests and try to run those under risk management process by means of AHP to get the respondedweights for those factors such as test procedure with average of weight (49.43%) indicates the caution to betaken during test beside major parameters such as sample size and mass in accurate manner to avoid risk intest and results obtained.
