Periodic Inspections of Hilo, Kahului, Laupahoehoe, and Nawiliwili Breakwaters, Hawaii

Abstract

As part of the Monitoring Completed Navigation Projects (MCNP) program "Periodic Inspections" work unit, five breakwaters from the Hawaiian Islands were inspected. The Hilo, Kahului east and west, Laupahoehoe, and Nawiliwili breakwaters were examined by walking inspection in the summer of 2005. Broken, cracked, and shifted concrete armor units and stones were recorded, and overall performance of the structure was noted. Photographs were taken and detailed notes recorded at each damage site. Observations and assessments are included for each of the five breakwaters inspected.
