For #1, manpower will likely not be the limiting factor, rather the cure time for whatever repairs are needed, assuming they are structural. and not aesthetic issues.I'm guessing three things:
1) A Sept 4 go-live of the LRT line may not be likely unless TransEd invests some serious manpower and overtime on rectifying this issue
2) There will be second thoughts about above-grade LRT (favored by Vinesh Pratap) vs ground-level LRT
3) Above-grade LRT is another master stroke of competency by TransEd
Depends what the problem is, and I don't think anyone here knows enough to even speculate what might be a fix or not. Besides, bracing onto a cracked concrete surface sounds like a recipe for more cracking and won't so much if the pier has any major issuesI wonder if there's a way to add additional bracing to the supports.
