In their Cambridge Street outdoor atellier the Chinese artisans have set up several tent shelters and work stations.
The long concrete pad shown running from the tent to the foreground has a uniform slope on its right edge. Looking closely, notice the forms are also curved to fit this casting bed. Presumably some parts of the arch require angled surfaces for the front or back of the pieces.
Some of the first cast pieces. Several different designs have now been cast. The arch is symmetrical front to back and side to side, so multiple pieces of each element is required.
Work shelter on the site.
