Construction challenges at the Portugues RCC dam, Puerto Rico

  • R. Ibanez de Aldecoa, D. Hernandez and E. Carlsson
  • Vol. 22 - Issue 5, 2015

The Portugues dam was completed in late 2013. The scheme included construction of a 67-m high single centred arch-gravity structure with a crest length of 375 m and 270 000 m3 of RCC. This paper addresses particular constraints encountered during construction, including: a lack of local, experienced personnel; limited availability of materials and equipment; complex geology at the dam foundation; a very seasonally wet climate with frequent river floods during the wet season; and, high temperatures for placing the concrete.
