and grouting costs were increased due to more difficult forming and access for drill rigs. Varty
et al. (1985) indicate that the HEC reverted to the Cethana type layout for the 80 m high
Crotty Dam. This layout was also adopted for the Foz do Areia Dam because, although exca-
vation was increased, this was compensated by better control of rockfill under the perimetric
joint, a more straightforward concreting scheme and simpler drilling of grout holes (Pinto
et al., 1985). Cooke (2000) gives some suggestions on plinth layout.
