Abstract
The objective of this study revolves around the analysis of the safety risks
involved within a large construction project, and the respective economic effects.
This analysis is fundamental for the safety management and cost reduction of
accidents.
The case study is the result of the safety coordination of systems, and of the
harmonization between the project owner, the safety coordinator and the
contractor. The result of this collaboration is and adequate strategy to prevent the
risks during the construction of a large hydro-electric dam in the north of
Portugal. The project is part of a governmental plan to invest in the energy
obtained from hydraulic sources. The dam in the north of Portugal is located in a
river and near the confluence with the river Douro. It will have a capacity of
storage that will be strategic to the electricity generation in the country. It has
two storage-pumped plants equipped with reversible units. The construction
volume covers around 700000 m3 of concrete, 600000 m3 of excavation and an
installed power of 170 MW. This dam presents a strategic value since it will
increase the water supply reserves for domestic and industrial use. It will be the
largest reserve of water in Portugal.
The safety risk evaluation on this construction project was carried out using
simulation tools of the different phases of construction according to the tasks of
the program plan. This overall analysis of the risks related with the planned tasks
provides a sequence of risks over the duration of the project. The simulation
allows the analysis to identify peaks and levels of high risks that are identified.
The method proposes a scale to classify risks that is compatible with probability
of occurrence and gravity of the consequences. There is also a systematic
