If brick is in bad condition, the last thing you do is sandblast it; sandblasting destroys hard surfaces and exposes the rougher, more porous interior of bricks to the elements, making them deteriorate even more quickly. It's done very rarely these days since the industry learned that lesson, and when it is, the pressure is generally lower than it used to be, water is used more often than sand now. and it's mainly done in select spots now that have an overabundance of surface accumulation, and not applied overall until a brick facade looks entirely 'clean' again. Generally a patina is left these days.They could have just sandblasted the brick and stabilized the mortar, and left it at that. The imperfections and texture would provide character in a city that desperately needs it.
At the same time, the life of damaged brick can be extended by painting it, and that requires a thorough cleaning before applying a masonry primer, and then generally a thick latex paint with elastodynamic properties to cope with heat, cold, and wet weather without fracturing... which is what naked, damaged brick with a crumbling surface will do if you don't paint it.
