The opening photo of the 2 men walking on the viaduct tells me all I need to know about this project. Both men are wearing reflective vests (that's good) both men are not wearing protective hard hats (that's bad)  they also don't appear tp be wearing steel toe boots(that' bad) which tells me there is not much regard for safety on this rail system. I worked on 4 major rail projects throughout SEA and the middle east. Come on my projects looking like that and I would put you on the first plane home
