Speedy construction of the highest RCC gravity dam in Lao PDR

The outstanding production rate of RCC placement achieved during the construction of the main dam at the Nam Ngiep 1 hydro project ranks this RCC dam as one of the fastest to be constructed in the world to date, but also ranked it as one of the most efficiently constructed dams in terms of batching plant rated capacity and actual quantities of RCC produced and placed. This paper discusses the construction techniques and solutions adopted during construction to achieve high productivity and efficiency while retaining the required high quality.
