I’m about 100 messages behind, still. Apologies if this has already been addressed.
If you look at that wall on Google Maps and follow that damage just above the curve, you’ll find many places as the wall height increases where the capstones have failed and need to be replaced/reset. The height and the weight of the stone def make the repairs here a team effort, IMO. I don’t consider it a trivial job.
That said, if you follow the wall to the bridge and go across Flatiron Crossing, the sister wall on the other side appears to have a potentially serious structural problem — either a crack or a shifting of a bunch of stones due to hydrostatic pressure or something. This side of the bridge seems like a much bigger job that what I expected BM to be involved with, TBH.
But who knows. As has been noted previously, we can’t even confirm that this is the job BM had been contracted to do. But both sides of the bridge have retaining walls that are certainly in need of repair.
MOO.
