ABSTRACT

The effective organization of the whole risk management process, based on the early coordination between all the stakeholders, plays a fundamental role in underground works. To define the risk management process during the construction and for the durability of the Pakal Dul Hydroelectric Project structures, two main references have been considered: the “Joint Code of Practice for Risk Management of Tunnel Works in the UK” (BTS), and the “Recommendation on the characterization of geological, hydrogeological and geotechnical uncertainties and risks” (AFTES). This process has been organized in four levels, that are: Risk Management System, Risk Management Plan, Risk Assessment, and Mitigation Measures Management. The effective communication and the early coordination between the parties, as well as the prompt and precise definition of a coding system, are fundamental to limit all shortcomings in the risk management process. To this purpose, a Risk Management Committee supporting the construction process should be established.
