The life expectancy of a steel concrete structure is over 100 years. However, this aqueduct was experiencing settling, tilting, and cracking within few years of construction. This was a recurrent theme we saw in many of the other constructions in Korea and the reason was the loss of construction function of the bridge bearings. The bearings that lost their function did not get fixed and the problem kept reoccurring. The problem increased from 1 area to 3 areas. Korea E&C did not just fix the ones that were defected. We researched and analyzed what went wrong and came up with preventative solutions.
increased to 3 areas when the first tilted area did not get taken care of 30 months ago
