Masonry construction, safety: Bricklayer holding trowel and level erects end block on wall. The mason stands on 2-2"x10" wood planks supported by side brackets attached to vertical tubes of welded tubular steel walk-thru scaffold. Mason is unsafe, because he is exposed to 20' fall without fall protection.
5-2"x10" planks form material platforms below and above, just behind mason, on which mortar boxs, mortar boards, and stacks of concrete block are placed to provide masons the materials they need to erect wall.
Extending out from the exterior side of concrete block wall are the corrugated steel wire eye segment of a 2-piece adjustable tie system into which the pentile segment embedded in the mortar of the brick veneer exterior wall surface to provide lateral support (support against wind) to the brick.
