Puerto Rican Dam a First for Roller-Compacted Concrete Technology
Located 3 miles northwest of Ponce, Puerto Rico, the Portugues Dam was constructed as part of a flood control project. The $216.8-million project included the construction of a 220-ft-high, roller-compacted concrete single-center thick arch dam with a crest length of 1,230 ft and a 110.6-ft-thick base. Construction required an estimated 367,000 cu yd of roller-compacted concrete (RCC), an approach that lowered costs. The dam is the first single-center arched RCC dam built in the U.S. and the first RCC project in Puerto Rico.
