According to Panos Prevedouros, a professor of civil engineering at the University of Hawaii, “they should have a minimum life of 30 years, not much maintenance, but anywhere between 30 and 50 years, they ought to be replaced.”
Prevedouros says there could be more culverts nearby that will eventually need repairs.
“Some of them are susceptible because Kakaako part of the time it’s under the water horizon [water table], so a lot of them are under conditions that they lead to deterioration, faster deterioration,” he said.
