Table 8 Pohoiki Breakwater Pohoiki Bay, Hawaii, Hawaii Date(s) Construction and Rehabilitation History A 90-ft dolos-armored structure with a concrete rib cap was con- structed in 1979 at a cost of approximately $335,500 (Figure 19). The structure was designed for 12-ft depth-limited breaking waves at the structure. The wave condition has reportedly occurred on several occasions since completion of construction, and the struc- ture shows no signs of deterioration. The 6-ton unreinforced dolosse (two layers) exceeded the needed weight for the design conditions but were found to be more economical than a lighter weight in that fewer units were needed. All existing dolosse breakage (5 units) occurred during construction and were left on the structure. Figure 20 is an aerial photograph of the break- water taken in 1984. TYPICAL BREAKWATER SECTION.
