The tem excavation can be simply defined as a form of earthwork including all the earthworks like underground working, tunneling, shafting, and trenching. It is the responsibility of the authorities to perform risk and hazards assessment before starting the process of excavation. The outcomes of this method depend on the evaluation of the risks. It is essential that risk assessment of the project is carried out by the authorities for the assessment of risks and hazards related to the project (Hughes and Ferrett, 2012, pp.234-238).
