Pads lighter than designed have been used for supporting beams in HCMC’s metro line No.1. This could have caused cracks seen in October.
The HCMC Management Authority for Urban Railways (MAUR), investor of the first metro line, said EB1 and EB4, two Elastomeric Laminated Bearings pads on the metro line’s elevated section, weigh 117 kilos, nine kilos lighter than the design approved five years ago.
