More problems on Honolulu light rail.

Spport columns have observed cracks showing up.  The question becomes are the cracks too deep to allow water and some salty mist to get to te re bar and cause premature rusting.  some how poor inspections, slump tests, concrete mix, among other possibilities.

Cracks found in columns at Honolulu’s rail line (msn.com)

"Cement Job"  What resorces does Hawaii have for native cement manufacturing? In Ravena NY the Cement Factory is HUGE with its own barge and rail terminal

It's not supposed to result in a rail line, it's a way to shovel money to the unions and contractors

While not tremendously exciting, this ACI video discusses how Hawaii gets cement - spoiler: large ships from the mainland are involved.

Cannot imagine the cost of cement in Hawaii.  Its heavy weight which is one reason cements plants all over US to limit rail or sometimes trucking to haul shorter distances.  Much heavier than coal or even Brightline's import of Canadian ballast.  Costs by ship must be high and then trucking to concrete plant.  Gives incentative to scrimp on cement for concrete.

Scrimp with the potential to reenact Champlain Towers South - yep thats the ticket to build you engineering cred.
