It was a very busy day on the site today. The second row of walers is being installed around the lower set of tiebacks and is now about halfway completed. This morning, the vertical rows of painted dots on the steel panels were each gone over with what appeared to be a small grinding or sanding wheel; by the end of the day (bottom picture), long bolts* had been inserted at each of the dots. This thing is really being built to last!
* I've just learned that these are shear studs, rather than bolts. [Updated 8 June]
